Fossil Fuel Companies Acknowledge Climate Crisis While Evading Legal Accountability
In a significant shift, major fossil fuel corporations have moved beyond outright denial of climate change in legal proceedings, now accepting the scientific consensus that human activities are driving global warming. However, new research highlights that these companies are employing sophisticated strategies to contest their legal responsibility for the resulting environmental damage.
From Denial to Deflection: The New Corporate Playbook
A study published in the journal Transnational Environmental Law provides the first systematic analysis of how industry giants like Shell, Chevron, RWE, and TotalEnergies defend themselves in climate-related lawsuits worldwide. The research identifies three primary tactics used to avoid liability, marking a departure from earlier eras of corporate climate denial.
Strategy One: Shifting Blame to Society and Governments
Companies argue that climate change is a collective issue stemming from societal energy demand, not from their own supply activities. For instance, Chevron and Shell have cited the IPCC's Fifth Assessment Report, emphasizing that emissions are driven by factors like population growth and economic activity, thereby positioning responsibility on modern industrial society as a whole.
In a notable case, RWE, a German energy firm, defended against a lawsuit by Peruvian farmer Saúl Luciano Lliuya, who claimed the company's emissions contributed to glacial retreat threatening his home. RWE's lawyers contended that their emissions were produced "for the common good to ensure a stable energy supply," framing fossil fuel production as a passive response to demand rather than an active driver of harm.
Similarly, Shell, in an appeal against Dutch environmental groups demanding a 45% emissions cut by 2030, argued that the energy transition should be managed by governments, not individual companies. This approach recasts courts as inappropriate venues for climate action, advocating for political processes instead.
Technical and Scientific Challenges in Court
Strategy Two: Questioning Legal Causation
While not disputing the reality of climate change, companies challenge the legal link between their specific emissions and observed harms. In the RWE case, lawyers contested a peer-reviewed study attributing flood risks in Peru to human-caused warming, arguing that CO2 molecules are "indistinguishable from each other," making it impossible to trace individual emissions to specific damages.
In Italy, Eni faced a lawsuit from Greenpeace and citizens over its emissions, with its defence characterising attribution science as nascent and non-standardised. This pattern persists globally, with firms accepting climate science for understanding warming but disputing its application in establishing legal responsibility.
Strategy Three: Undermining Scientific Credibility
Companies also attack the impartiality of climate scientists. In the RWE case, lawyers used tweets by leading scientist Friederike Otto, where she described climate lawsuits as "interesting," to argue she was too biased to serve as a court expert. When independent studies were submitted, they scrutinised authors' social media and professional connections, alleging coordinated networks.
In the US, defendants in a lawsuit by Oregon's Multnomah County against ExxonMobil sought to dismiss peer-reviewed evidence by claiming undisclosed links between lawyers and study authors, further complicating the legal landscape.
The Future of Climate Litigation
As fossil fuel companies uniformly accept climate science while refusing accountability, the central battleground in courts worldwide is shifting from whether climate change is happening to who bears legal and financial responsibility. This evolution underscores the growing complexity of holding corporations accountable for environmental impacts, with implications for future policy and regulatory frameworks.
The research, led by Noah Walker-Crawford, a fellow at Imperial College London and the London School of Economics, highlights how corporate arguments are reshaping climate litigation, moving beyond denial to nuanced defences that challenge liability on multiple fronts.
