A study published in the journal npj Climate Action by researchers from Boston 探花直播 (BU) and the 探花直播 of Cambridge, evaluates two promising tools to fight misleading native advertising campaigns put forth by big oil companies.</p> <p>Many major news organisations now offer corporations the opportunity to pay for articles that mimic in tone and format the publication鈥檚 regular reported content. These 鈥榥ative advertisements鈥 are designed to camouflage seamlessly into their surroundings, containing only subtle disclosure messages often overlooked or misunderstood by readers. Fossil fuel companies are spending tens of millions of dollars to shape public perceptions of the climate crisis.</p> <p>鈥淏ecause these ads appear on reputable, trusted news platforms, and are formatted like reported pieces, they often come across to readers as genuine journalism,鈥 said lead author Michelle Amazeen from BU鈥檚 College of Communication. 鈥淩esearch has shown native ads are really effective at swaying readers鈥 opinions.鈥</p> <p> 探花直播study is the first to investigate how two mitigation strategies 鈥 disclosures and inoculations 鈥 may reduce climate misperceptions caused by exposure to native advertising from the fossil fuel industry. 探花直播authors found that when participants were shown a real native ad from ExxonMobil, disclosure messages helped them recognise advertising, while inoculations helped reduce their susceptibility to misleading claims.</p> <p>鈥淎s fossil fuel companies invest in disguising their advertisements, this study furthers our understanding of how to help readers recognise when commercial content is masquerading as news and spreading climate misperceptions,鈥 said co-author Benjamin Sovacool, also from BU.</p> <p>鈥淥ur study showed that communication-led climate action is possible and scalable by countering covert greenwashing campaigns, such as native advertising, at the source,鈥 said co-author Dr Ramit Debnath from Cambridge鈥檚 Department of Architecture. 鈥 探花直播insights we鈥檝e gained from this work will help us design better interventions for climate misinformation.鈥</p> <p> 探花直播research builds on a growing body of work assessing how people recognise and respond to covert misinformation campaigns. By better understanding these processes, the researchers hope that they can prevent misinformation from taking root and changing people鈥檚 beliefs and actions on important issues like climate change.</p> <h2>鈥 探花直播Future of Energy鈥 ad</h2> <p>Starting in 2018, readers of 探花直播New York Times website encountered what appeared to be an article, titled 鈥<a href="https://www.nytimes.com/paidpost/exxonmobil/the-future-of-energy-it-may-come-from-where-you-least-expect.html"> 探花直播Future of Energy</a>,鈥 describing efforts by oil and gas giant ExxonMobil to invest in algae-based biofuels. Because it appeared beneath the Times鈥 masthead, in the outlet鈥檚 typical formatting and font, many readers likely missed the small banner at the top of the page mentioning that it was an ad sponsored by ExxonMobil.</p> <p> 探花直播ad, part of a $5-million-dollar campaign, neglected to mention the company鈥檚 staggering carbon footprint. It also omitted key context, <a href="https://theintercept.com/2019/10/31/exxon-mobil-massachusetts-climate-change-lawsuit-greenwashing/"><em> 探花直播Intercept</em> reported</a>, like that the stated goal for algae-based biofuel production would represent only 0.2% of the company鈥檚 overall refinery capacity. In a lawsuit against ExxonMobil, Massachusetts cited the ad as evidence of the company鈥檚 鈥渇alse and misleading鈥 communications, with several states pursuing similar cases.</p> <h2>Putting two interventions to the test</h2> <p> 探花直播researchers examined how more than a thousand participants responded to 鈥 探花直播Future of Energy鈥 ad in a simulated social media feed.</p> <p>Before viewing the ad, participants saw one, both, or neither of the following intervention messages:</p> <p>An inoculation message designed to psychologically 鈥榠noculate鈥 readers from future influence by broadly warning them of potential exposures to misleading paid content. In this study, the inoculation message was a fictitious social media post from United Nations Secretary-General Antonio Guterres reminding people to be wary of online misinformation.</p> <p>A disclosure message with a simple line of text appearing on a post. In this study, the text 鈥淧aid Post by ExxonMobil鈥 accompanied the piece. Studies have shown that more often than not, when native ads are shared on social media, this disclosure disappears.</p> <h2>Bolstering psychological resilience to native ads</h2> <p> 探花直播team found that the ad improved opinions of ExxonMobil鈥檚 sustainability across the study鈥檚 many participants, regardless of which messages they saw, but that the interventions helped to reduce this effect. Some of the key findings include:</p> <p> 探花直播presence of a disclosure more than doubled the likelihood that a participant recognised the content as an ad. However, the participants who had seen a disclosure and those who had not were equally likely to agree with the statement 鈥渃ompanies like ExxonMobil are investing heavily in becoming more environmentally friendly.鈥</p> <p>Inoculation messages were much more effective than disclosures at protecting people鈥檚 existing beliefs on climate change, decreasing the likelihood that participants would agree with misleading claims presented in the ad.</p> <p>鈥淒isclosures helped people recognise advertising. However, they didn鈥檛 help them recognise that the material was biased and misleading,鈥 said Amazeen. 鈥淚noculation messaging provides general education that can be used to fill in that gap and help people resist its persuasive effects. Increasing general awareness about misinformation strategies used by self-interested actors, combined with clearer labels on sponsored content, will help people distinguish native ads from reported content.鈥</p> <h2>Reference</h2> <p><em>Michelle A Amazeen et al. 鈥<a href="https://www.nature.com/articles/s44168-025-00209-6"> 探花直播鈥淔uture of Energy鈥?

For example, in many countries, women are less likely to own land and resources to protect them in post-disaster situations, and have less control over income and less access to information, resulting in increased vulnerability to acute and long-term climate change impacts.</p>&#13; &#13; <p>They are also particularly at risk from climate-related threats to their health, say the researchers. For example, studies have linked high temperatures to adverse birth outcomes such as spontaneous preterm births, pre-eclampsia and birth defects. Extreme events, which are expected to become more likely and intense due to climate change, also take a severe toll on women's social, physical, and mental well-being. Numerous studies highlight that gender-based violence is reported to increase during or after extreme events, often due to factors related to economic instability, food insecurity, disrupted infrastructure and mental stress.</p>&#13; &#13; <p>Dr Kim Robin van Daalen, a former Gates Cambridge Scholar at the 探花直播 of Cambridge, and researcher at the Barcelona Supercomputing Center (BSC), said: 鈥淕iven how disproportionately climate change affects women, girls and gender minorities 鈥 a situation that is only likely to get worse 鈥 we need to ensure that their voices are heard and meaningfully included in discussions of how we respond to this urgent climate crisis. This is not currently happening at anywhere near the level it needs to.鈥</p>&#13; &#13; <p> 探花直播team summarised the inclusion of gender, health and their intersection in key decisions and initiatives under the United Nations Framework Convention on Climate Change (UNFCCC), and analysed gender representation among representatives of Party and Observer State delegations at COPs between 1995-2023. Progress has been slow, they say.</p>&#13; &#13; <p>They highlight how previous scholars have consistently noted that emphasis remains mainly on achieving a gender 鈥榥umber-based balance鈥 in climate governance, over exploring gender-specific risks and vulnerabilities and addressing their root causes. They also discuss how there remains limited recognition of the role climate change has in worsening gendered impacts on health, including gender-based violence and the lack of safeguarding reproductive health in the face of climate change.</p>&#13; &#13; <p>Although the situation is slowly improving, at COP28, almost three-quarters (73%) of Party delegations were still majority men, and only just over one in six (16%) showed gender parity (that is, 45-55% women). In fact, gender parity has only been achieved in the 鈥榃estern European and Other鈥 UN grouping (which also includes North America, Australia and New Zealand). Based on current trends, several countries - particularly those in the Asia-Pacific and Africa regions - are expected to take at least a decade from COP28 before reaching gender parity in their delegations.</p>&#13; &#13; <p>Dr聽Ramit Debnath, former Gates Cambridge Scholar and now an Assistant Professor at Cambridge, said: 鈥 探花直播urgency of climate action, as well as the slow understanding of climate, gender, and health connections, is cause for concern. Institutions like the UNFCCC must recognize these disparities, design appropriate methods to improve gender parity in climate governance, and keep these representation gaps from growing into societal and health injustices.鈥</p>&#13; &#13; <p>Beyond ensuring that their voices are heard, more equitable inclusion of women has consistently been suggested to transform policymaking across political and social systems, including the generation of policies that better represent women鈥檚 interests. Previous recent analyses of 49 European countries revealed that greater women鈥檚 political representation correlates with reduced inequalities in self-reported health, lower geographical inequalities in infant mortality and fewer disability-adjusted life-years lost across genders.</p>&#13; &#13; <p>Similar positive findings have been reported related to environmental policies, with women鈥檚 representation in national parliaments being associated with increased ratification of environmental treaties and more stringent climate change policies. For example, women legislators in the European parliament and US House of Representatives have been found to be more inclined to support environmental legislation than men.</p>&#13; &#13; <p>Dr Ronita Bardhan, Associate Professor at the 探花直播 of Cambridge, said: "Achieving equitable gender representation in climate action is not just about fairness - it's a strategic necessity with significant co-benefits. We can shape climate policies and infrastructure that address a broader spectrum of societal needs, leading to more inclusive solutions enhancing public health, social equity, and environmental resilience."</p>&#13; &#13; <p>While the researchers鈥 analyses focused on achieving gender balance, studies on women鈥檚 involvement in climate governance suggest that increased representation does not by itself always lead to meaningful policy changes. Even when formally included, women鈥檚 active participation in male-dominated institutions is often constrained by existing social and cultural norms, implicit biases and structural barriers.</p>&#13; &#13; <p>Dr van Daalen added: 鈥淚f we鈥檙e to meaningfully incorporate gender into climate policy and practice, we need to understand the risks and vulnerabilities that are gender-specific and look at how we can address them and their root causes at all phases of programme and policy development.</p>&#13; &#13; <p>鈥淏ut we also need to resist reducing women to a single, homogenous group, which risks deepening existing inequalities and overlooks opportunities to address the needs of all individuals. It is crucial to recognise the diversity of women and their embodiment of multiple, intersecting identities that shape their climate experiences as well as their mitigation and adaptation needs.鈥</p>&#13; &#13; <p> 探花直播team also highlights that gender-diverse people face unique health and climate-related risks due to their increased vulnerability, stigma, and discrimination. For example, during and after extreme events, transgender people in the United States report being threatened or prohibited access to shelters. Similarly, in the Philippines, Indonesia, and Samoa, gender-diverse individuals often face discrimination, mockery, and exclusion from evacuation centres or access to food. Yet, say the researchers, there are major gaps in knowledge about the health implications of climate change for such groups.</p>&#13; &#13; <p>Find out how Cambridge's pioneering research in climate and nature is regenerating nature, rewiring energy, rethinking transport and redefining economics - <a href="/climate-and-nature">forging a future for our planet</a>.</p>&#13; &#13; <p><em><strong>Reference</strong><br />&#13; Van Daalen, KR et al. <a href="https://doi.org/10.1016/S2542-5196(24)00270-5">Bridging the gender, climate, and health gap: the road to COP29.</a> Lancet Planetary Health; 11 Nov 2024; DOI: 10.1016/S2542-5196(24)00270-5</em></p>&#13; </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p>Climate governance is dominated by men, yet the health impacts of the climate crisis often affect women, girls, and gender-diverse people disproportionately, argue researchers ahead of the upcoming 29th United Nations Climate Summit (COP29) in Azerbaijan.</p>&#13; </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">Given how disproportionately climate change affects women, girls and gender minorities, we need to ensure that their voices are heard and meaningfully included in discussions of how we respond to this urgent climate crisis</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Kim van Daalen</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="https://commons.wikimedia.org/wiki/File:Flood_survival.jpg" target="_blank">Hansel ohioma</a></div></div></div><div class="field field-name-field-image-desctiprion field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Surviving the flood at Ahoada in Rivers state Nigeria</div></div></div><div class="field field-name-field-cc-attribute-text field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p><a href="https://creativecommons.org/licenses/by-nc-sa/4.0/" rel="license"><img alt="Creative Commons License." src="/sites/www.cam.ac.uk/files/inner-images/cc-by-nc-sa-4-license.png" style="border-width: 0px; width: 88px; height: 31px;" /></a><br />&#13; 探花直播text in this work is licensed under a <a href="https://creativecommons.org/licenses/by-nc-sa/4.0/">Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License</a>.

Survey participants also differed in their personal income, with half of participants belonging to the top 10% of income in their country.</p> <p> 探花直播vast majority of participants across the four countries overestimated the average personal carbon footprint of the poorest 50% and underestimated those of the richest 10% and 1%.</p> <p>However, participants from the top 10% were more likely to support certain climate policies, such as increasing the price of electricity during peak periods, taxing red meat consumption or subsidising carbon dioxide removal technologies such as carbon capture and storage.</p> <p> 探花直播researchers say that this may reflect generally higher education levels among high earners, a greater ability to absorb price-based policies or a stronger preference for technological solutions to the climate crisis. 探花直播<a href="https://www.nature.com/articles/s41558-024-02130-y">results</a> are reported in the journal <em>Nature Climate Change</em>.</p> <p>Although the concept of a personal carbon or environmental footprint has been used for over 40 years, it became widely popularised in the mid-2000s, when the fossil fuel company BP ran a large advertising campaign encouraging people to determine and reduce their personal carbon footprint.</p> <p>鈥淭here are definitely groups out there who would like to push the responsibility of reducing carbon emissions away from corporations and onto individuals, which is problematic,鈥 said co-author Dr Ramit Debnath, Assistant Professor and Cambridge Zero Fellow at the 探花直播 of Cambridge. 鈥淗owever, personal carbon footprints can illustrate the profound inequality within and between countries and help people identify how to live in a more climate-friendly way.鈥</p> <p>Previous research has shown widespread misperceptions about how certain consumer behaviours affect an individual's carbon footprint. For example, recycling, shutting off the lights when leaving a room and avoiding plastic packaging are lower-impact behaviours that are overestimated in terms of how much they can reduce one鈥檚 carbon footprint. On the other end, the impact of behaviours such as red meat consumption, heating and cooling homes, and air travel all tend to be underestimated.</p> <p>However, there is limited research on whether these misperceptions extend to people鈥檚 perceptions of the composition and scale of personal carbon footprints and their ability to make comparisons between different groups.</p> <p> 探花直播four countries selected for the survey (Denmark, India, Nigeria and the US) were chosen due to their different per-capita carbon emissions and their levels of economic inequality. Within each country, approximately 1,000 participants were surveyed, with half of each participant group from the top 10% of their country and the other half from the bottom 90%.</p> <p>Participants were asked to estimate the average personal carbon footprints specific to three income groups (the bottom 50%, the top 10%, and the top 1% of income) within their country. Most participants overestimated the average personal carbon footprint for the bottom 50% of income and underestimated the average footprints for the top 10% and top 1% of income.</p> <p>鈥淭hese countries are very different, but we found the rich are pretty similar no matter where you go, and their concerns are different to the rest of society,鈥 said Debnath. 鈥淭here鈥檚 a huge contrast between billionaires travelling by private jet while the rest of us drink with soggy paper straws: one of those activities has a big impact on an individual carbon footprint, and one doesn鈥檛.鈥</p> <p> 探花直播researchers also looked at whether people鈥檚 ideas of carbon footprint inequality were related to their support for different climate policies. They found that Danish and Nigerian participants who underestimated carbon footprint inequality were generally less supportive of climate policies. They also found that Indian participants from the top 10% were generally more supportive of climate policies, potentially reflecting their higher education and greater resources.</p> <p>鈥淧oorer people have more immediate concerns, such as how they鈥檙e going to pay their rent, or support their families,鈥 said first author Dr Kristian Steensen Nielsen from Copenhagen Business School. 鈥淏ut across all income groups, people want real solutions to the climate crisis, whether those are regulatory or technological. However, the people with the highest carbon footprints bear the greatest responsibility for changing their lifestyles and reducing their footprints.鈥</p> <p>After learning about the actual carbon footprint inequality, most participants found it slightly unfair, with those in Denmark and the United States finding it the most unfair. However, people from the top 10% generally found the inequality fairer than the general population, except in India. 鈥淭his could be because they鈥檙e trying to justify their larger carbon footprints,鈥 said Debnath.</p> <p> 探花直播researchers say that more work is needed to determine the best ways to promote fairness and justice in climate action across countries, cultures and communities.</p> <p>鈥淒ue to their greater financial and political influence, most climate policies reflect the interests of the richest in society and rarely involve fundamental changes to their lifestyles or social status,鈥 said Debnath.</p> <p>鈥淕reater awareness and discussion of existing inequality in personal carbon footprints can help build political pressure to address these inequalities and develop climate solutions that work for all,鈥 said Nielsen.</p> <p> 探花直播study also involved researchers from Justus-Liebig- 探花直播 Giessen, Murdoch 探花直播 and Oxford 探花直播. 探花直播research was supported in part by the Carlsberg Foundation, the Bill &amp; Melinda Gates Foundation, the Quadrature Climate Foundation and the Swiss National Science Foundation.</p> <p><em><strong>Reference:</strong><br /> Kristian S Nielsen et al. 鈥<a href="https://www.nature.com/articles/s41558-024-02130-y">Underestimation of personal carbon footprint inequality in four diverse countries</a>.鈥 Nature Climate Change (2024).

However, missing information from certain locations on the planet, time periods or societal dynamics create 鈥渉oles鈥 in the data that can lead to unreliable climate predictions and misleading conclusions.</p>&#13; &#13; <p>Primary author and Cambridge Zero Fellow Dr Ramit Debnath said that individuals with access to technology, such as scientists, teachers, professionals and businesses in the Global North are more likely to see their climate priorities and perceptions reflected in the digital information widely available for AI use.</p>&#13; &#13; <p>By contrast, those without the same access to technology, such as indigenous communities in the Global South, are more likely to find their experiences, perceptions and priorities missing from those same digital sources.</p>&#13; &#13; <p>鈥淲hen the information on climate change is over-represented by the work of well-educated individuals at high-ranking institutions within the Global North, AI will only see climate change and climate solutions through their eyes,鈥 Debnath said.聽</p>&#13; &#13; <p>鈥淏iased鈥 AI has the potential to misrepresent climate information.</p>&#13; &#13; <p>For example, it could generate ineffective weather predictions or underestimate carbon emissions from certain industries, which could then misguide governments trying to create policy and regulations aimed at mitigating or adapting to climate change.聽</p>&#13; &#13; <p>AI-supported climate solutions which spring from biased data are in danger of harming under-represented communities, particularly those in the Global South with scant resources. These are often the same communities who also find themselves most vulnerable to the extreme weather events caused by climate change such as floods, fires, heatwaves and drought.</p>&#13; &#13; <p>That is a combination which could lead to 鈥渟ocietal tipping events鈥, the paper warns.聽</p>&#13; &#13; <p>However, these 鈥渄ata holes鈥 can be filled by human knowledge. 探花直播authors advocate for a human-in-the loop design to offer AI climate change programmes with a sense check on which data is used and the context in which it is used, in an effort to improve the accuracy of predictions and the usefulness of any conclusions.</p>&#13; &#13; <p> 探花直播authors mention popular AI chatbot model ChatGPT, which has recently taken the world by storm for its ability to communicate conversationally with human users. On ChatGPT, the AI can ask its human users follow-up questions, admit mistakes, challenge incorrect premises and reject inappropriate requests.</p>&#13; &#13; <p>This 鈥榟uman-in-the-loop鈥 style AI allows bias to be noticed and corrected, the authors said. Users can input critical social information, such as existing infrastructure and market systems, to allow the AI to better anticipate any unintended socio-political and economic consequences of climate action.聽</p>&#13; &#13; <p>鈥淣o data is clean or without prejudice, and this is particularly problematic for AI which relies entirely on digital information,鈥 co-author, Cambridge Zero Director and climate scientist Professor Emily Shuckburgh said.</p>&#13; &#13; <p>In highlighting the importance of globally inclusive datasets, the paper also promotes broadband internet access as a public necessity, rather than a private commodity, to engage as many users as possible in the design of AI for contemporary conversations about climate action.</p>&#13; &#13; <p> 探花直播paper concludes that human-guided technology remains instrumental in the development of socially responsible AI.</p>&#13; &#13; <p>Less-biased AI will be critical to our understanding of how the climate is changing, and consequently in guiding realistic solutions to mitigate and adapt to the on-going climate crisis, the authors said.</p>&#13; &#13; <p>聽Professor Shuckburgh, who also leads the UK national research funding body鈥檚 (UKRI) Centre for Doctoral Training on the Application of AI to the study of Environmental Risks (AI4ER), said that recognising the issue of data justice is the first step to better outcomes.聽聽</p>&#13; &#13; <p>鈥淥nly with an active awareness of this data injustice can we begin to tackle it, and consequently, to build better and more trustworthy AI-led climate solutions,鈥 she said.</p>&#13; </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p>Biased artificial intelligence needs human help to avoid harmful climate action, Cambridge researchers say.</p>&#13; </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">No data is clean or without prejudice, and this is particularly problematic for AI which relies entirely on digital information</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Professor Emily Shuckburgh</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/" target="_blank">Photo by NOAA on Unsplash</a></div></div></div><div class="field field-name-field-image-desctiprion field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Vehicles with weather observation equipment track a storm</div></div></div><div class="field field-name-field-slideshow field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/sites/default/files/graphic.jpg" title="" class="colorbox" data-colorbox-gallery="" data-cbox-img-attrs="{&quot;title&quot;: &quot;&quot;, &quot;alt&quot;: &quot;&quot;}"><img class="cam-scale-with-grid" src="/sites/default/files/styles/slideshow/public/graphic.jpg?itok=7WnfLRAk" width="590" height="288" alt="" title="" /></a></div></div></div><div class="field field-name-field-cc-attribute-text field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"><p><a href="https://creativecommons.org/licenses/by-nc-sa/4.0/" rel="license"><img alt="Creative Commons License." src="/sites/www.cam.ac.uk/files/inner-images/cc-by-nc-sa-4-license.png" style="border-width: 0px; width: 88px; height: 31px;" /></a><br />&#13; 探花直播text in this work is licensed under a <a href="https://creativecommons.org/licenses/by-nc-sa/4.0/">Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License</a>.
