Recent revelations from internal documents have thrust ExxonMobil into a renewed spotlight, exposing its historical efforts to fund climate denial campaigns in Latin America. As the world prepares for the 30th Conference of the Parties (COP30) in Belém, Brazil, starting November 10, 2025, these disclosures highlight a deepening dilemma for the oil giant: balancing its fossil fuel legacy with mounting pressure from regional activists and global stakeholders for accountable climate finance. Environmental groups across Latin America are now channeling this outrage into peaceful advocacy, pushing for resolutions that compel corporations like Exxon to contribute to funding mechanisms aimed at mitigating climate impacts in vulnerable regions.
The documents, uncovered and reported by The Guardian, detail how Exxon financed the Atlas Network—a U.S.-based coalition of over 500 free-market thinktanks—to propagate climate skepticism in Latin America during the late 1990s and early 2000s. The goal was explicit: to make the Global South “less inclined” to back UN-led climate treaties. Exxon provided funding, including a $50,000 check in 1998 (equivalent to about $100,000 today), to support translations of denial literature into Spanish and Chinese, as well as organizing seminars and media outreach. This “behind-the-scenes” strategy, as described in Atlas Network correspondence, avoided public association with Exxon while influencing policymakers and public opinion against international climate action.
Key initiatives included partnerships with local thinktanks such as Argentina’s Fundación República para una Nueva Generación and Brazil’s Instituto Liberal. These groups produced a Spanish translation of a booklet by climate denier Fred Singer, titled “The Scientific Case Against the Global Climate Treaty,” which falsely claimed no significant scientific support for global warming threats. Ahead of COP4 in Buenos Aires in 1998, seminars featured U.S. deniers like Patrick Michaels, who dismissed climate concerns as “hysteria.” These events targeted ministers, politicians, editorial boards, and business leaders, aiming to erode support for binding emissions reductions.
This history echoes Exxon’s broader pattern of climate deception, documented in timelines by organizations like Greenpeace and the Union of Concerned Scientists. Internal Exxon studies from the 1970s and 1980s accurately predicted climate change impacts, yet the company pivoted to doubt-sowing campaigns, as revealed in NPR investigations showing executives raising internal doubts about emission cuts as recently as 2023. The “Climate Deception Dossiers” from the Union of Concerned Scientists further outline how fossil fuel majors, including Exxon, blocked actions to curb carbon emissions.
In Latin America, where climate vulnerabilities are acute— from Amazon deforestation to coral reef die-offs—these revelations have ignited fresh campaigns. Indigenous and environmental groups, such as those affiliated with the WWF and local NGOs in Brazil and Argentina, are advocating for peaceful resolutions through shareholder activism and international forums. For instance, campaigns are urging Exxon to align with climate finance pledges, including contributions to the UN’s Loss and Damage Fund, established at COP27 and operationalized at COP28. Activists argue that companies profiting from fossil fuels should fund adaptation in regions like the Amazon, where tipping points loom within 10-20 years without intervention.
These efforts draw on a legacy of litigation and resolutions. In Puerto Rico, a 2022 lawsuit against Exxon and other oil firms alleged deception on climate risks, though it was voluntarily dismissed without prejudice in May 2025. Broader analyses, like those in the Journal of Human Rights Practice, explore the political ecology of climate remedies in Latin America, emphasizing community-led approaches to hold corporations accountable. Shareholder resolutions have proven effective; in 2017, despite board opposition, 62% of Exxon investors voted for annual reports on long-term climate impacts. More recently, Exxon has sued to block investor proposals on emissions cuts, as seen in 2024 actions against groups like Follow This and Arjuna Capital.
Latin American campaigns are framing their demands around “peaceful climate finance resolutions,” seeking non-confrontational paths like voluntary corporate commitments and multilateral agreements. In Brazil, host of COP30, groups are lobbying for enhanced Nationally Determined Contributions (NDCs) that incorporate corporate liability for historical emissions. The Union of Concerned Scientists, attending COP30, stresses expediting transitions from fossil fuels and urging richer nations—and by extension, their corporations—to provide finance for renewables. This aligns with calls to reform international financial institutions to prioritize climate-resilient projects in the region.
Exxon’s response has been defensive. In its 2024 “Advancing Climate Solutions” report, the company touts innovations like carbon capture but critics argue it downplays the need for rapid fossil fuel phase-outs. Recent lawsuits, such as Exxon’s October 2025 challenge to California’s climate disclosure laws, claim violations of free speech, further fueling perceptions of denial. A Nature study from March 2025 highlights how Exxon’s misleading ads impact public beliefs on climate action.
The dilemma for Exxon is stark: continue resisting or pivot toward genuine contributions. Campaigns in Latin America, amplified on platforms like X where users share outrage over the revelations, emphasize collaboration over conflict. Posts from environmental journalists and activists decry the “death cult” tactics, urging accountability ahead of COP30.
As COP30 approaches, these campaigns could influence outcomes on finance goals. The New Collective Quantified Goal (NCQG) from COP29 aims for trillions in annual funding, with Latin American nations pushing for polluter-pays principles. If successful, resolutions could compel Exxon to redirect profits toward sustainable initiatives, such as reforestation and renewable energy in the Amazon.
Critics note implementation hurdles, given historical finance shortfalls. Yet, the momentum from these peaceful efforts—rooted in evidence of past deception—offers a pathway to resolution. By addressing its denial legacy, Exxon could transform from antagonist to partner in climate finance, benefiting Latin America’s ecosystems and communities.
The broader implications extend to global equity. Latin America’s campaigns underscore that climate justice requires holding historical emitters accountable, fostering resolutions that harmonize corporate responsibility with sustainable development. As delegates gather in Belém, the focus will be on turning revelations into reforms, ensuring finance flows to those most affected.
In summary, Exxon’s dilemma encapsulates the tension between profit-driven denial and the imperative for ethical finance. Latin American advocates are leading with peaceful strategies, hoping to resolve this through dialogue and policy, paving the way for a resilient future.
