  • Why is there no life on Mars? Nasa’s rover finds mineral clue in Martian desert

    Why is there no life on Mars? Nasa’s rover finds mineral clue in Martian desert

    PARIS, July 3 — Why is Mars barren and uninhabitable, while life has always thrived here on our relatively similar planet Earth?

    A discovery made by a Nasa rover has offered a clue for this mystery, new research said yesterday, suggesting that while rivers once sporadically flowed on Mars, it was doomed to mostly be a desert planet.

    Mars is thought to currently have all the necessary ingredients for life except for perhaps the most important one: liquid water.

    However, the red surface is carved out by ancient rivers and lakes, showing that water once flowed on our nearest neighbour.

    There are currently several rovers searching Mars for signs of life that could have existed back in those more habitable times, millions of years ago.

    Earlier this year, Nasa’s Curiosity rover discovered a missing piece in this puzzle: rocks that are rich in carbonate minerals.

    These “carbonates” — such as limestone on Earth — act as a sponge for carbon dioxide, pulling it in from the atmosphere and trapping it in rock.

    A new study, published in the journal Nature, modelled exactly how the existence of these rocks could change our understanding of Mars’s past.

    Brief ‘oases’

    Lead study author Edwin Kite, a planetary scientist at the University of Chicago and a member of the Curiosity team, told AFP it appeared there were “blips of habitability in some times and places” on Mars.

    But these “oases” were the exception rather than the rule.

    On Earth, carbon dioxide in the atmosphere warms the planet. Over long timescales, the carbon becomes trapped in rocks such as carbonates.

    Then volcanic eruptions spew the gas back into the atmosphere, creating a well-balanced climate cycle supportive of consistently running water.

    However, Mars has a “feeble” rate of volcanic outgassing compared to Earth, Kite said. This throws off the balance, leaving Mars much colder and less hospitable.

    According to the modelling research, the brief periods of liquid water on Mars were followed by 100 million years of barren desert — a long time for anything to survive.

    It is still possible that there are pockets of liquid water deep underground on Mars we have not yet found, Kite said.

    Nasa’s Perseverance Rover, which landed on an ancient Martian delta in 2021, has also found signs of carbonates at the edge of dried-up lake, he added.

    Next, the scientists hope to discover more evidence of carbonates.

    Kite said the best proof would be returning rock samples from the Martian surface back to Earth — both the United States and China are racing to do this in the next decade.

    Are we alone?

    Ultimately, scientists are searching for an answer to one of the great questions: how common are planets like Earth that can harbour life?

    Astronomers have discovered nearly 6,000 planets beyond our Solar System since the early 1990s.

    But only for Mars and Earth can scientists study rocks which allow them to understand the planet’s past, Kite said.

    If we do determine that Mars never hosted even tiny micro-organisms during its watery times, that would indicate it is difficult to kick-start life across the universe.

    But if we discover proof of ancient life, that would “basically be telling us the origin of life is easy on a planetary scale,” Kite said. — AFP

  • Cervical Cancer Risk Overlooked After Age 65

    Cervical Cancer Risk Overlooked After Age 65

    TOPLINE:

    Analysis of over 2.1 million women in China revealed that those aged 65 years or older vs those younger than 65 years had significantly higher rates of high-risk human papillomavirus (hr-HPV) infection (13.67% vs 8.08%) and cervical cancer (0.092% vs 0.01%) although most guidelines recommend discontinuing screening for women aged 65 years or older with a normal screening history.

    METHODOLOGY:

    • Researchers conducted a retrospective analysis of cervical cancer screening data from Shenzhen, China (2017-2023), to assess hr-HPV distribution and cervical intraepithelial neoplasia grade 2 or worse (CIN2+) prevalence in women aged 65 years or older vs those younger than 65 years.
    • Data collection encompassed 628 healthcare facilities, including 496 community health centers, 94 hospitals, 11 maternal and child health hospitals, and 27 other medical facilities.
    • Clinical records included demographic information, cytology results, HPV testing covering 14 hr-HPV genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68), and colposcopy/biopsy outcomes.
    • Analysis included 2,152,766 complete records from an initial collection of 2,580,829, yielding an 83.4% data validity rate.

    TAKEAWAY:

    • Analysis of 2,152,766 records revealed that women aged 65 years or older (n = 17,420; 0.81%) vs those younger than 65 years showed higher hr-HPV prevalence (13.67% vs 8.08%), CIN2+ detection rate (0.333% vs 0.155%), and cancer rate (0.092% vs 0.01%; P for all < .001).
    • Single, double, and triple hr-HPV infections were found in 10.56%, 2.32%, and 0.57% of women aged 65 years or older, with CIN2+ detection rates of 2.01%, 2.73%, and 4.04%, respectively, all exceeding rates in those younger than 65 years (P < .001).
    • A significant dose-response relationship emerged between hr-HPV infections and CIN2+ risk in women aged 65 years or older (P for trend < .001), with odds ratios being 55.86 (95% CI, 21.81-143.07), 65.95 (95% CI, 22.63-192.18), and 85.45 (95% CI, 24.15-302.35) for single, double, and triple infections, respectively.

    IN PRACTICE:

    “Currently, there is a significant global gap in cervical cancer prevention for older women, and urgent action is needed. First, screening and early diagnosis for women aged ≥ 65 should be strengthened, including affordable screening services and age-appropriate technologies to detect and treat precancerous lesions. Additionally, community engagement, health education, and media campaigns can raise awareness of cervical cancer risks and prevention among older women, encouraging active participation in screening programs,” authors of the study wrote.

    SOURCE:

    The study was led by Zichen Ye, He Wang, and Yingyu Zhong, who served as joint first authors. It was published online in Gynecology and Obstetrics Clinical Medicine.

    LIMITATIONS:

    The study faced several limitations despite using high-quality, large-sample, real-world cervical cancer screening data collected over 7 years in Shenzhen. Because women aged 65 years or older were not included in the national target screening population, participants may have had symptoms or concerns, introducing potential selection bias. The low number of hr-HPV infections in this age group led to some results trending toward extremes, affecting result stability. Additionally, data from a single region in China limited generalizability to other populations. The researchers could not obtain specific information about the types of cytologic detection products and HPV genotyping products used, which may have affected result precision and comparability.

    DISCLOSURES:

    The study was supported by the Sanming Project of Medicine in Shenzhen (SZSM202211032). The authors reported having no relevant conflicts of interest.

    This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

  • Cable laying about to resume at 725-kilometer link to connect UK and Germay for the first time

    Cable laying about to resume at 725-kilometer link to connect UK and Germay for the first time

    Italian cabling giant Prysmian Group will soon kick off the second phase of cabling works in UK waters for NeuConnect, a high-voltage submarine cable that will create the first direct energy transmission link between the UK and Germany.

    The 725-kilometer land and subsea cable system is said to create an “invisible energy highway” capable of transferring 1.4 GW of electricity, enough to power 1.5 million homes, in either direction, with converter stations on the Isle of Grain in Kent and Wilhelmshaven in northern Germany.

    Construction work at the UK site on the Isle of Grain began in the summer of 2023, with construction in Germany following in May 2024.

    Prysmian completed the first phase of cabling works in UK waters in November 2024, installing 56 kilometers of onshore and subsea cables.

    The Italian company will on July 7 recommence cable installation operations using its cable laying vessel (CLV) Leonardo da Vinci. This second campaign is expected to be completed in September.

    The third phase of cabling works is planned to begin mid-November, with completion slated for January 2026.

    NeuConnect is expected to be operational by 2028.

  • UK insolvency service reframes view on ‘creditor’ definition

    UK insolvency service reframes view on ‘creditor’ definition

    The Insolvency Service, the government agency responsible for administering bankruptcies and liquidations in the UK, has published updated guidance that reframes its previously held view that a creditor is set at the point of entry into an insolvency procedure and remains a creditor even if payment in full is subsequently made.

    The guidance, which was published in its most recent ‘Dear IP’ issue at the end of June, confirmed that the term “creditor” will be context specific and the office holder will be permitted to exercise their professional judgment in relation to whether paid creditors remain creditors. The update reframes the agency’s view on what defines a creditor and follows two court cases last year that found that the consent of paid secured creditors was not required in the context of an administration extension.  

    In 2024, the court in cases Boughey & Anor v Toogood International Transport and Agricultural Services Ltd and Re Pindar Scarborough Ltd (in administration) – commonly referred to as ‘Re Pindar’ and ‘Re Toogood’ – was asked to consider the issue of paid secured creditors in the context of administration extensions.

    An administration automatically ends after one year, however, few administrations are concluded so quickly, so the administration can be extended by the court or for a period of up to one year by creditor consent.

    Approaching secured and preferential creditors who have been repaid in full for their approval or consent has been a thorn in the side of administrators for a number of years. Many secured creditors, understandably, consider that once they had been repaid, they no longer have an interest in decisions in the insolvency process – so neither approve nor object to the request. 

    Consent refers to the actual consent of both secured and unsecured creditors unless the administrator has made a statement under paragraph 52(1)(b) of schedule b1 to the Insolvency Act 1986, in which case the consent of each secured creditor is required, or, if a distribution to preferential creditors is to be made, then the consent of each secured creditor and the preferential creditors of the company is required. The rationale is those creditors with an economic interest in the company are the decision makers.

    In the Re Pindar and Re Toogood cases the court said that the definition of “secured creditor” in the Insolvency Act 1986 should be read in the present tense so that a secured creditor for decision-making purposes would only be a creditor who holds security in relation to a debt that is still owed.

    In Re Toogood, the judge commented: “There is no reason why a commercial organisation such as a bank that has been repaid in full should have to be bothered thereafter with making administration decisions that do not affect it. Why should it spend its time, unremunerated, in doing so?” 

    The court’s view in these cases conflicted with the Insolvency Service’s interpretation at the time. In April 2022, the agency said: “It has been the government’s position for some time that the classification of a creditor is set at the point of entry to the procedure and that this remains, even if payment in full is subsequently made” – so underlining the need to obtain paid creditors’ consent, notwithstanding the practical difficulty obtaining it.

    The judge in the Re Toogood case, His Honour Judge Matthew, challenged this view, stating: “If the government wishes there to be a different result, then it must legislate more clearly than it has done and moreover explain why those with no economic interest in the outcome of an administration should nevertheless determine what happens.”

    In its latest guidance, the Insolvency Service stated it will no longer contend that the meaning of the word ‘creditor’ is fixed and crystallised at the date of entry into an insolvency procedure. The agency said it will be a matter for the officeholder’s professional judgement, with reference to the specific circumstances of the insolvency case in question, to determine whether an interpretation of the word “creditor” in an insolvency law provision will exclude a creditor whose debt has been repaid. 

    The update also highlighted that the officeholder should give “particular consideration” to whether the creditor in question may be prejudiced or disadvantaged by losing their status upon full repayment, in which case their creditor status should not be detached from them.

    Commenting on the development, James Hillman, restructuring and insolvency expert at Pinsent Masons said: “The Insolvency Service’s reframed view will be welcome news for officeholders and brings its view closer to the view of the courts in relation to an issue that has been problematic for a number of years.”

    The updated guidance provides welcome clarity on the definition of a ‘creditor’ in insolvency legislation, but Hillman said there are likely to be further court decisions on other procedural matters where uncertainty remains. “It does not deal with issues around obtaining consent where all secured creditors and preferential creditors have been paid or there weren’t any secured creditors to begin with, so we may see more court applications in this area,” he said. “However, the latest guidance is a positive step forward.”

  • Your essential guide to climate finance

    Your essential guide to climate finance

    The global ecosystem of climate finance is complex, constantly changing and sometimes hard to understand. But understanding it is critical to demanding a green transition that’s just and fair. That’s why The Conversation has collaborated with climate finance experts to create this user-friendly guide, in partnership with Vogue Business. With definitions and short videos, we’ll add to this glossary as new terms emerge.

    Blue bonds

    Blue bonds are debt instruments designed to finance ocean-related conservation, like protecting coral reefs or sustainable fishing. They’re modelled after green bonds but focus specifically on the health of marine ecosystems – this is a key pillar of climate stability.

    By investing in blue bonds, governments and private investors can fund marine projects that deliver both environmental benefits and long-term financial returns. Seychelles issued the first blue bond in 2018. Now, more are emerging as ocean conservation becomes a greater priority for global sustainability efforts.

    Carbon border adjustment mechanism

    Did you know that imported steel could soon face a carbon tax at the EU border? That’s because the carbon border adjustment mechanism is about to shake up the way we trade, produce and price carbon.

    The carbon border adjustment mechanism is a proposed EU policy to put a carbon price on imports like iron, cement, fertiliser, aluminium and electricity. If a product is made in a country with weaker climate policies, the importer must pay the difference between that country’s carbon price and the EU’s. The goal is to avoid “carbon leakage” – when companies relocate to avoid emissions rules and to ensure fair competition on climate action.

    But this mechanism is more than just a tariff tool. It’s a bold attempt to reshape global trade. Countries exporting to the EU may be pushed to adopt greener manufacturing or face higher tariffs.

    The carbon border adjustment mechanism is controversial: some call it climate protectionism, others argue it could incentivise low-carbon innovation worldwide and be vital for achieving climate justice. Many developing nations worry it could penalise them unfairly unless there’s climate finance to support greener transitions.

    Carbon border adjustment mechanism is still evolving, but it’s already forcing companies, investors and governments to rethink emissions accounting, supply chains and competitiveness. It’s a carbon price with global consequences.

    Carbon budget

    The Paris agreement aims to limit global warming to 1.5°C above pre-industrial levels by 2030. The carbon budget is the maximum amount of CO₂ emissions allowed, if we want a 67% chance of staying within this limit. The Intergovernmental Panel on Climate Change (IPCC) estimates that the remaining carbon budgets amount to 400 billion tonnes of CO₂ from 2020 onwards.

    Think of the carbon budget as a climate allowance. Once it has been spent, the risk of extreme weather or sea level rise increases sharply. If emissions continue unchecked, the budget will be exhausted within years, risking severe climate consequences. The IPCC sets the global carbon budget based on climate science, and governments use this framework to set national emission targets, climate policies and pathways to net zero emissions.

    By Dongna Zhang, assistant professor in economics and finance, Northumbria University

    Carbon credits

    Carbon credits are like a permit that allow companies to release a certain amount of carbon into the air. One credit usually equals one tonne of CO₂. These credits are issued by the local government or another authorised body and can be bought and sold. Think of it like a budget allowance for pollution. It encourages cuts in carbon emissions each year to stay within those global climate targets.

    The aim is to put a price on carbon to encourage cuts in emissions. If a company reduces its emissions and has leftover credits, it can sell them to another company that is going over its limit. But there are issues. Some argue that carbon credit schemes allow polluters to pay their way out of real change, and not all credits are from trustworthy projects. Although carbon credits can play a role in addressing the climate crisis, they are not a solution on their own.

    By Sankar Sivarajah, professor of circular economy, Kingston University London

    Carbon credits explained.

    Carbon offsetting

    Carbon offsetting is a way for people or organisations to make up for the carbon emissions they are responsible for. For example, if you contribute to emissions by flying, driving or making goods, you can help balance that out by supporting projects that reduce emissions elsewhere. This might include planting trees (which absorb carbon dioxide) or building wind farms to produce renewable energy.

    The idea is that your support helps cancel out the damage you are doing. For example, if your flight creates one tonne of carbon dioxide, you pay to support a project that removes the same amount.

    While this sounds like a win-win, carbon offsetting is not perfect. Some argue that it lets people feel better without really changing their behaviour, a phenomenon sometimes referred to as greenwashing.

    Not all projects are effective or well managed. For instance, some tree planting initiatives might have taken place anyway, even without the offset funding, deeming your contribution inconsequential. Others might plant the non-native trees in areas where they are unlikely to reach their potential in terms of absorbing carbon emissions.

    So, offsetting can help, but it is no magic fix. It works best alongside real efforts to reduce greenhouse gas emissions and encourage low-carbon lifestyles or supply chains.

    By Sankar Sivarajah, professor of circular economy, Kingston University London

    Carbon offsetting explained.

    Carbon tax

    A carbon tax is designed to reduce greenhouse gas emissions by placing a direct price on CO₂ and other greenhouse gases.

    A carbon tax is grounded in the concept of the social cost of carbon. This is an estimate of the economic damage caused by emitting one tonne of CO₂, including climate-related health, infrastructure and ecosystem impacts.

    A carbon tax is typically levied per tonne of CO₂ emitted. The tax can be applied either upstream (on fossil fuel producers) or downstream (on consumers or power generators). This makes carbon-intensive activities more expensive, it incentivises nations, businesses and people to reduce their emissions, while untaxed renewable energy becomes more competitively priced and appealing.

    Carbon tax was first introduced by Finland in 1990. Since then, more than 39 jurisdictions have implemented similar schemes. According to the World Bank, carbon pricing mechanisms (that’s both carbon taxes and emissions trading systems) now cover about 24% of global emissions. The remaining 76% are not priced, mainly due to limited coverage in both sectors and geographical areas, plus persistent fossil fuel subsidies. Expanding coverage would require extending carbon pricing to sectors like agriculture and transport, phasing out fossil fuel subsidies and strengthening international governance.

    What is carbon tax?

    Sweden has one of the world’s highest carbon tax rates and has cut emissions by 33% since 1990 while maintaining economic growth. The policy worked because Sweden started early, applied the tax across many industries and maintained clear, consistent communication that kept the public on board.

    Canada introduced a national carbon tax in 2019. In Canada, most of the revenue from carbon taxes is returned directly to households through annual rebates, making the scheme revenue-neutral for most families. However, despite its economic logic, inflation and rising fuel prices led to public discontent – especially as many citizens were unaware they were receiving rebates.

    Carbon taxes face challenges including political resistance, fairness concerns and low public awareness. Their success depends on clear communication and visible reinvestment of revenues into climate or social goals. A 2025 study that surveyed 40,000 people in 20 countries found that support for carbon taxes increases significantly when revenues are used for environmental infrastructure, rather than returned through tax rebates.

    Climate resilience

    Floods, wildfires, heatwaves and rising seas are pushing our cities, towns and neighbourhoods to their limits. But there’s a powerful idea that’s helping cities fight back: climate resilience.

    Resilience refers to the ability of a system, such as a city, a community or even an ecosystem – to anticipate, prepare for, respond to and recover from climate-related shocks and stresses.

    Sometimes people say resilience is about bouncing back. But it’s not just about surviving the next storm. It’s about adapting, evolving and thriving in a changing world.

    Resilience means building smarter and better. It means designing homes that stay cool during heatwaves. Roads that don’t wash away in floods. Power grids that don’t fail when the weather turns extreme.

    It’s also about people. A truly resilient city protects its most vulnerable. It ensures that everyone – regardless of income, age or background – can weather the storm.

    And resilience isn’t just reactive. It’s about using science, local knowledge and innovation to reduce a risk before disaster strikes. From restoring wetlands to cool cities and absorb floods, to creating early warning systems for heatwaves, climate resilience is about weaving strength into the very fabric of our cities.

    By Paul O’Hare, senior lecturer in geography and development, Manchester Metropolitan University

    The meaning of climate resilience.

    Climate risk disclosure

    Climate risk disclosure refers to how companies report the risks they face from climate change, such as flood damage, supply chain disruptions or regulatory costs. It includes both physical risks (like storms) and transition risks (like changing laws or consumer preferences).

    Mandatory disclosures, such as those proposed by the UK and EU, aim to make climate-related risks transparent to investors. Done well, these reports can shape capital flows toward more sustainable business models. Done poorly, they become greenwashing tools.

    By Narmin Nahidi, assistant professor in finance at the University of Exeter

    Emissions trading scheme

    An emissions trading scheme is the primary market-based approach for regulating greenhouse gas emissions in many countries, including Australia, Canada, China and Mexico.

    Part of a government’s job is to decide how much of the economy’s carbon emissions it wants to avoid in order to fight climate change. It must put a cap on carbon emissions that economic production is not allowed to surpass. Preferably, the polluters (that’s the manufacturers, fossil fuel companies) should be the ones paying for the cost of climate mitigation.

    Regulators could simply tell all the firms how much they are allowed to emit over the next ten years or so. But giving every firm the same allowance across the board is not cost efficient, because avoiding carbon emissions is much harder for some firms (such as steel producers) than others (such as tax consultants). Since governments cannot know each firm’s specific cost profile either, it can’t customise the allowances. Also, monitoring whether polluters actually abide by their assigned limits is extremely costly.

    An emissions trading scheme cleverly solves this dilemma using the cap-and-trade mechanism. Instead of assigning each polluter a fixed quota and risking inefficiencies, the government issues a large number of tradable permits – each worth, say, a tonne of CO₂-equivalent (CO₂e) – that sum up to the cap. Firms that can cut greenhouse gas emissions relatively cheaply can then trade their surplus permits to those who find it harder – at a price that makes both better off.

    Environmental, social and governance (ESG) investing

    ESG investing stands for environmental, social and governance investing. In simple terms, these are a set of standards that investors use to screen a company’s potential investments.

    ESG means choosing to invest in companies that are not only profitable but also responsible. Investors use ESG metrics to assess risks (such as climate liability, labour practices) and align portfolios with sustainability goals by looking at how a company affects our planet and treats its people and communities. While there isn’t one single global body governing ESG, various organisations, ratings agencies and governments all contribute to setting and evolving these metrics.

    For example, investing in a company committed to renewable energy and fair labour practices might be considered “ESG aligned”. Supporters believe ESG helps identify risks and create long-term value. Critics argue it can be vague or used for greenwashing, where companies appear sustainable without real action. ESG works best when paired with transparency and clear data. A barrier is that standards vary, and it’s not always clear what counts as ESG.

    Why do financial companies and institutions care? Issues like climate change and nature loss pose significant risks, affecting company values and the global economy.

    Investing with ESG in mind can help manage these risks and unlock opportunities, with ESG assets projected to reach over US$40 trillion (£30 trillion) by 2030.

    However, gathering reliable ESG information can be difficult. Companies often self-report, and the data isn’t always standardised or up to date. Researchers – including my team at the University of Oxford – are using geospatial data, like satellite imagery and artificial intelligence, to develop global databases for high-impact industries, across all major sectors and geographies, and independently assess environmental and social risks and impacts.

    For instance, we can analyse satellite images of a facility over time to monitor its emissions effect on nature and biodiversity, or assess deforestation linked to a company’s supply chain. This allows us to map supply chains, identify high-impact assets, and detect hidden risks and opportunities in key industries, providing an objective, real-time look at their environmental footprint.

    The goal is for this to improve ESG ratings and provide clearer, more consistent insights for investors. This approach could help us overcome current data limitations to build a more sustainable financial future.

    Environmental, social and governance investing explained.

    Financed emissions

    Financed emissions are the greenhouse gas emissions linked to a bank’s or investor’s lending and investment portfolio, rather than their own operations. For example, a bank that funds a coal mine or invests in fossil fuels is indirectly responsible for the carbon those activities produce.

    Measuring financed emissions helps reveal the real climate impact of financial institutions not just their office energy use. It’s a cornerstone of climate accountability in finance and is becoming essential under net zero pledges.

    By Narmin Nahidi, assistant professor in finance at the University of Exeter

    Green bonds

    Green bonds are loans issued to fund environmentally beneficial projects, such as energy-efficient buildings or clean transportation. Investors choose them to support climate solutions while earning returns.

    Green bonds are a major tool to finance the shift to a low-carbon economy by directing finance toward climate solutions. As climate costs rise, green bonds could help close the funding gap while ensuring transparency and accountability.

    Green bonds are required to ensure funds are spent as promised. For instance, imagine a city wants to upgrade its public transportation by adding electric buses to reduce pollution. Instead of raising taxes or slashing other budgets, the city can issue green bonds to raise the necessary capital. Investors buy the bonds, the city gets the funding, and the environment benefits from cleaner air and fewer emissions.

    The growing participation of government issuers has improved the transparency and reliability of these investments. The green bond market has grown rapidly in recent years. According to the Bank for International Settlements, the green bond market reached US$2.9 trillion (£2.1 trillion) in 2024 – nearly six times larger than in 2018. At the same time, annual issuance (the total value of green bonds issued in a year) hit US$700 billion, highlighting the increasing role of green finance in tackling climate change.

    By Dongna Zhang, assistant professor in economics and finance, Northumbria University

    Just transition

    Just transition is the process of moving to a low-carbon society that is environmentally sustainable and socially inclusive. In a broad sense, a just transition means focusing on creating a more fair and equal society.

    Just transition has existed as a concept since the 1970s. It was originally applied to the green energy transition, protecting workers in the fossil fuel industry as we move towards more sustainable alternatives.

    These days, it has so many overlapping issues of justice hidden within it, so the concept is hard to define. Even at the level of UN climate negotiations, global leaders struggle to agree on what a just transition means.

    The big battle is between developed countries, who want a very restrictive definition around jobs and skills, and developing countries, who are looking for a much more holistic approach that considers wider system change and includes considerations around human rights, Indigenous people and creating an overall fairer global society.

    A just transition is essentially about imagining a future where we have moved beyond fossil fuels and society works better for everyone – but that can look very different in a European city compared to a rural setting in south-east Asia.

    For example, in a British city it might mean fewer cars and better public transport. In a rural setting, it might mean new ways of growing crops that are more sustainable, and building homes that are heatwave resistant.

    Loss and damage

    A global loss and damage fund was agreed by nations at the UN climate summit (Cop27) in 2022. This means that the rich countries of the world put money into a fund that the least developed countries can then call upon when they have a climate emergency.

    The World Bank has agreed to run the loss and damage fund but they are charging significant fees for doing so.

    At the moment, the loss and damage fund is made up of relatively small pots of money. Much more will be needed to provide relief to those who need it most now and in the future.

    Mitigation v adaptation

    Mitigation means cutting greenhouse gas emissions to slow climate change. Adaptation means adjusting to its effects, like building sea walls or growing heat-resistant crops. Both are essential: mitigation tackles the cause, while adaptation tackles the symptoms.

    Globally, most funding goes to mitigation, but vulnerable communities often need adaptation support most. Balancing the two is a major challenge in climate policy, especially for developing countries facing immediate climate threats.

    Nationally determined contributions

    Nationally determined contributions (NDCs) are at the heart of the Paris agreement, the global effort to collectively combat climate change. NDCs are individual climate action plans created by each country. These targets and strategies outline how a country will reduce its greenhouse gas emissions and adapt to climate change.

    Each nation sets its own goals based on its own circumstances and capabilities – there’s no standard NDC. These plans should be updated every five years and countries are encouraged to gradually increase their climate ambitions over time.

    The aim is for NDCs to drive real action by guiding policies, attracting investment and inspiring innovation in clean technologies. But current NDCs fall short of the Paris agreement goals and many countries struggle to turn their plans into a reality. NDCs also vary widely in scope and detail so it’s hard to compare efforts across the board. Stronger international collaboration and greater accountability will be crucial.

    Natural capital

    Fashion depends on water, soil and biodiversity – all natural capital. And forward-thinking designers are now asking: how do we create rather than deplete, how do we restore rather than extract?

    Natural capital is the value assigned to the stock of forests, soils, oceans and even minerals such as lithium. It sustains every part of our economy. It’s the bees that pollinate our crops. It’s the wetlands that filter our water and it’s the trees that store carbon and cool our cities.

    If we fail to value nature properly, we risk losing it. But if we succeed, we unlock a future that is not only sustainable but also truly regenerative.

    My team at the University of Oxford is developing tools to integrate nature into national balance sheets, advising governments on biodiversity, and we’re helping industries from fashion to finance embed nature into their decision making.

    Net zero

    Reaching net zero means reducing the amount of additional greenhouse gas emissions that accumulate in the atmosphere to zero. This concept was popularised by the Paris agreement, a landmark deal that was agreed at the UN climate summit (Cop21) in 2015 to limit the impact of greenhouse gas emissions.

    There are some emissions, from farming and aviation for example, that will be very difficult, if not impossible, to reach absolute zero. Hence, the “net”. This allows people, businesses and countries to find ways to suck greenhouse gas emissions out of the atmosphere, effectively cancelling out emissions while trying to reduce them. This can include reforestation, rewilding, direct air capture and carbon capture and storage. The goal is to reach net zero: the point at which no extra greenhouse gases accumulate in Earth’s atmosphere.

  • FCA policy statement and consultation on non-financial misconduct published

    FCA policy statement and consultation on non-financial misconduct published

    FCA rule changes will clarify that serious bullying and harassment at any financial institution, including in some instances where it takes place in an individual’s private life, may affect whether they satisfy conduct rules and meet the fit and proper test.

    As we previously explained, in 2023 the PRA and FCA each published consultation papers (CP 18/23 and 23/20 respectively) on diversity and inclusion (D&I) in financial services, highlighting the continued regulatory concern in this area. The 2023 consultation papers proposed reforms that included requiring financial services firms to maintain a D&I strategy, mandating that firms set diversity targets, and implementing additional D&I disclosure requirements for large firms. However, in March this year, we reported that the PRA and FCA announced that they were dropping these plans in an effort to boost growth in the UK. 

    Another important focus of the 2023 consultations was non-financial misconduct (NFM), a topic that had been on the regulators’ radars for some time as part of a broader focus on culture. The outcome of the NFM aspects of the consultations has been highly anticipated.

    The FCA has now published in a policy statement its proposed rules on NFM alongside a consultation on draft guidance to support firms to apply its NFM rules if needed (CP 25/18). The policy statement extends the scope of the FCA’s NFM rules while the consultation sets out amended guidance in relation to NFM for the purposes of the conduct rules and fitness and propriety (F&P) assessments.

    Extending existing NFM rules to include non-banks

    The FCA Code of Conduct (COCON) sets out conduct rules for staff and provides guidance about those rules to firms whose staff are subject to them. The FCA has statutory powers as an enforcement body for breaches of COCON. 

    While NFM can amount to a breach of FCA rules in any firm, under the current rules, NFM will more commonly breach COCON in a bank than in a non-bank. To address this, yesterday’s publication confirms that the FCA is widening the scope of its rules for non-banks to align the approach across all SM&CR firms and bring more instances of NFM into its regulatory remit.

    The NFM rule covers unwanted conduct that has the purpose or effect of violating an individual’s dignity or creating an intimidating, hostile, degrading or humiliating or offensive environment for an individual, or conduct that is violent towards an individual. 

    The new rule comes into effect on 1 September 2026 and will not apply retrospectively. 

    Consultation on additional Handbook guidance

    The 2023 proposals included new guidance aimed at integrating NFM within the workplace and, in some circumstances, similarly serious behaviour in an individual’s personal or private life, into: (i) F&P assessments (for individuals performing a Senior Management Function or a certification function); (ii) COCON; and (iii) the suitability guidance on the Threshold Conditions for firms to carry on regulated activities.

    Yesterday’s consultation sets out amended proposals for potential new Handbook guidance in COCON and the Fit and Proper test for Employees and Senior Personnel (FIT), which aims to make it easier for SM&CR firms to interpret and consistently apply the conduct rules and to clarify statutory and FCA requirements for F&P. The FCA is seeking views on whether additional guidance is needed at all and, if so, on the form it should take. The FCA will only take the guidance forward if there is clear support for it to do so.

    The consultation on draft guidance closes on 10 September 2025.

    How has the COCON guidance changed since 2023?

    In 2023, the FCA made clear that not every instance of misconduct would amount to a breach. Factors to take into account when deciding whether misconduct was serious enough to amount to a breach included whether the conduct was repeated, the duration of the conduct, and the extent of the impact on the subject. Yesterday’s consultation contains new guidance and additional examples, including examples of scenarios illustrating the boundary between work and private life, material about the factors for determining whether NFM is serious enough to amount to a breach, and examples of reasonable steps for managers.

    The boundary between work and private life

    For instance, misconduct by a manager in relation to a member of the workforce at a social occasion organised by their firm would be in scope of COCON, but misconduct at a social occasion organised by them in their personal capacity would not. What was unclear in 2023 was what the FCA’s stance would be if misconduct occurred at a social occasion that took place after a firm-organised event. The proposed guidance now states that an occasion organised by the manager may be within the scope of COCON, taking into account that the manager’s direct reports may feel obliged to attend. If the event takes place after a firm event but at a separate location or venue, it may be within scope if it is a continuation of the first event or if the conduct started at the first event and continued in the new venue. Otherwise, COCON is likely to cease to apply because the connection between the event and the activities of the firm has been lost. 

    Further guidance is also provided on the use of social media. The FCA suggests that publishing material on a personal social media account is an example of how it is not possible to give a definitive answer to a scenario based on a single element. However, factors to consider include whether the material is directed at a fellow member of the workforce, whether the content of the social media posts is related to work at the firm, and whether the person uses a work-issued device. The fact that the person uploads the posts during working hours or while on the firm’s premises is not a strong factor pointing towards the application of COCON.

    Determining whether NFM is ‘serious’

    The use of the term ‘serious’ in COCON meant that the NFM had to have a seriously negative effect to amount to a potential rule breach. Following the 2023 consultation, there were concerns over the subjectivity of the term ‘serious’. Yesterday’s consultation confirms that the use of the term ‘serious’ is aimed at ensuring that minor incidents of poor workplace behaviour were not brought unnecessarily into scope of the FCA’s rules. The FCA has provided more guidance on factors for determining seriousness and the need to take an objective view. The FCA also clarifies that not all misconduct for which a firm might reasonably take disciplinary action under its own disciplinary policy will amount to a breach of COCON. The revised guidance makes it clear that seriousness is not the deciding or distinguishing factor in determining whether NFM is a breach of Conduct Rule 1 (acting with integrity) or Rule 2 (acting with due skill, care and diligence). In line with regulatory law, only deliberate or reckless misconduct is considered a breach of Rule 1. This means that in the absence of those factors, NFM is likely to be a breach of Rule 2. 

    Reasonable steps for managers

    The FCA makes clear in the updated guidance that a manager should try to prevent harassment and other kinds of misconduct and will not be in breach of Conduct Rule 2 if they have acted reasonably. Examples of conduct by a manager that might be a breach include failing to intervene to stop such behaviour where appropriate if the manager knows or should know of it and failing to take seriously or to deal appropriately with complaints of behaviour. The wider context is important here, for example any limits or constraints on a manager’s ability to act if it is the firm’s policy that the HR function deals with allegations of misconduct.

    How has the FIT guidance changed since 2023?

    FIT sets out factors to which the FCA and firms should have regard when assessing whether an individual is fit and proper to perform their role. 

    In 2023, the FCA proposed that serious NFM in work and personal life could be relevant to F&P assessments. The rationale used was: (i) the risk that if conduct occurred at work it could go to F&P; (ii) the conduct may show that the individual lacks moral soundness, rectitude and steady adherence to an ethical code, which in turn raises doubts as to whether they will follow the requirements of the regulatory system; or (iii) conduct that is so disgraceful or morally reprehensible or otherwise sufficiently serious could undermine public confidence in the financial sector. According to the FCA, there was considerable support for its 2023 FIT proposals. However, key concerns included how the FCA would expect firms to deal with NFM in private life, the intersection between work and private life and the language used in the FCA’s draft instrument. 

    NFM in private life

    In the new draft guidance, the FCA makes it clear that a firm will normally rely on formal findings, such as criminal convictions or the findings of a court, tribunal, regulator, arbitrator, public enquiry or other body, when assessing whether wrongdoing in private life has taken place. The FCA also clarifies that it does not expect firms to monitor their employees’ private lives to identify anything that is relevant to fitness. However, a firm may become aware of information about an individual’s private life that would – if substantiated – call into question their F&P. In these circumstances, the firm should consider what steps it can reasonably take to assess the possible impact, such as asking for an explanation from the member of staff where appropriate.

    As above, social media activity may be relevant to F&P for the same reasons as other conduct. The FCA makes clear that, in principle, a person can lawfully express in their private or personal life their views on social media, even if those views are controversial or offensive and even if work colleagues are upset by those views, without calling into question their fitness under FIT. However, if a person’s social media activity in their private life indicates a real risk that the person will breach the requirements and standards of the regulatory system, then such activity will be relevant to their F&P. Examples could include threats of violence or clear involvement in criminal activities.

    Subjective language and technical detail

    Terms used in 2023 such as ‘moral soundness’ and ‘disgraceful’ have been replaced with more neutral language in yesterday’s publication and the FCA has also included more examples of the types of conduct both inside and outside work or a regulated role that may be relevant to F&P, such as conduct that is dishonest or shows a lack of integrity as well as repeated minor breaches of law. 

    Proposals not taken forward 

    In 2023, the FCA proposed to extend the guidance on the Suitability Threshold Condition in its COND sourcebook to make it clear that NFM and discriminatory practices in firms are relevant to its assessment of their suitability to undertake regulated activities. It also consulted on updating the guidance around regulatory references in SYSC to make it clear that it might be necessary to provide information on NFM or misconduct outside work to a firm requesting a reference.

    Having considered the feedback, the FCA has decided not to proceed with its proposals for COND or SYSC. In relation to SYSC, the FCA’s existing rules on regulatory references require firms to disclose all breaches of the conduct rules for which disciplinary action was taken. Similarly, firms are required to provide any other information they reasonably believe to be relevant to the F&P assessment.

    Comment

    In 2023, the FCA and PRA set down a clear marker that they considered NFM as misconduct for regulatory purposes and that even conduct that occurs outside of the workplace could be relevant in certain circumstances. That was a significant, albeit not surprising, confirmation of the regulators’ approach. Yesterday’s publication only serves to underline the importance of NFM not just for banks, but for all firms bound by the SM&CR regime. Affected firms should consider taking steps now to ensure compliance ahead of the new rules taking effect next year.

  • Apple Makes Official Entry to Threads Platform

    Apple Makes Official Entry to Threads Platform

    It took time, but Apple has now joined Meta’s social media platform, Threads, nearly two years post-launch. Threads. Over 4.8 million people followed the verified @apple account right away. This resulted from Meta’s Instagram auto-follow function. All of the company’s Instagram followers were instantly added to the Threads account. The same strategy boosted Threads at its launch.

    Threads is still considered a growing alternative to X, formerly Twitter. However, its long-term engagement remains to be seen. Apple’s new account has not yet shared any posts. Its function and potential applications are currently unknown. However, as was done on X in the past, the business may employ Threads for promotional content.

    There, the company has over 9.8 million followers, though it does not engage in regular posting on that platform. However, Apple actively posts to its 34 million+ Instagram followers as part of its “Shot on iPhone” campaign. Now, threads could be used as a placeholder or as a new home for upcoming announcements or campaigns.

  • Bird flu: EFSA analyses situation in US and tracks possible routes of spread

    Bird flu: EFSA analyses situation in US and tracks possible routes of spread

    EFSA’s scientists highlight that key European stop-overs with high-density bird congregations, such as Iceland, Britain, Ireland, western Scandinavia, and large wetlands like the Wadden Sea on the Dutch, Danish and German coasts would be useful places for early detection of the virus during the seasonal migration of wild birds.  

    The report also addresses the potential for the virus to be introduced into Europe through trade, concluding that the importation of products with raw milk from affected areas in the USA cannot be completely excluded and therefore could be a possible pathway. The importation of dairy cows and bovine meat could also be a potential route for virus introduction. However, the virus has rarely been found in meat, animal imports are very limited, and very strict trade regulations are in place for meat and live animals entering the EU. 

    EFSA’s report also provides an overview of the situation in the USA, where 981 dairy herds across 16 states were affected between March 2024 and May 2025. The report, which was reviewed by the US authorities, highlights that cattle movement, low biosecurity, and shared farm equipment contributed to the spread of the virus.  

    By the end of the year, EFSA will assess the potential impact of this HPAI genotype entering Europe, recommending measures to prevent its spread.
