Climate Change Litigation: A Shift in Tactics by Fossil Fuel Giants
The era of outright corporate climate change denial is largely over. However, a significant shift has occurred within courtrooms globally. While some governments continue to downplay the severity of climate change, major fossil fuel companies – including Shell, Chevron, RWE, and TotalEnergies – are adopting a different approach. They now generally acknowledge that climate change is real, human-caused, and a serious threat. But this acceptance doesn’t translate into accepting responsibility.
From Denial to Deflection: New Legal Strategies
Recent research published in the journal Transnational Environmental Law provides the first systematic analysis of how these companies defend themselves in climate change litigation. The analysis of landmark lawsuits reveals three distinct strategies employed by fossil fuel companies to deflect blame.
1. The Collective Responsibility Argument
The most common argument centers around the idea that climate change is a collective problem driven by societal demand for energy, not by the companies that supply it. Companies like Chevron and Shell have even cited the same passage from the IPCC’s Fifth Assessment Report, highlighting factors like population size and economic activity, to argue that responsibility lies with modern industrial society as a whole.
RWE, a German energy giant, used a similar defense in a lawsuit brought by a Peruvian farmer whose livelihood was threatened by glacial retreat. Their lawyer argued that the company’s emissions were produced “for the common good to ensure a stable energy supply.” Shell, facing pressure to cut emissions by 45% by 2030, argued that the energy transition is the responsibility of governments, not individual companies. This framing positions political processes, rather than courts, as the appropriate venue for addressing climate change.
2. Challenging Legal Causation
Companies generally don’t dispute the science of climate change itself. Instead, they contest whether a clear legal link can be established between their emissions and specific climate impacts. In the RWE case, lawyers challenged a peer-reviewed study attributing flood risk to human-caused warming, not by denying the warming trend, but by questioning the certainty of the glacial model and arguing that CO2 molecules are “indistinguishable from each other,” making it impossible to trace specific emissions to specific harms.
Similarly, in Italy, Eni’s defense characterized attribution science – the field that links climate change to extreme weather events – as a nascent and non-standardized field. The consistent pattern is that while acknowledging the validity of climate science for understanding global warming, companies dispute its use as a basis for establishing legal responsibility.
3. Discrediting the Science and Scientists
A more aggressive tactic involves questioning the credibility of the scientists producing the climate research. In the RWE case, the company’s lawyers presented tweets from a leading climate scientist, Friederike Otto, suggesting bias because she had described climate lawsuits as “interesting.” They also attacked the professional associations and social media posts of researchers involved in independent attribution studies, alleging a coordinated network.
In the US, defendants in a lawsuit against ExxonMobil and other oil companies attempted to discredit peer-reviewed evidence by alleging undisclosed connections between the claimant’s lawyer and the studies’ authors. This tactic aims to sow doubt and undermine the scientific basis for holding companies accountable.
The Future of Climate Litigation
The central battleground in climate litigation is no longer whether climate change is happening, but rather who, legally and financially, bears the responsibility for it. Fossil fuel companies have effectively moved beyond denying the problem to defending their actions, and the courts will be the arena where this debate unfolds. Understanding these evolving legal strategies is crucial for advancing climate justice and holding polluters accountable.
