Over the last ten years, experts have discussed the extent to which the shift to clean energy threatens the oil and gas sector. The longer the transition to a sustainable economy takes, the more advantageous the position of these companies becomes. However, a fresh development is appearing as a crucial unpredictable element for the industry’s financial stability: the increasing drive to assign climate-related liabilities to specific corporations.
This trend is highlighted by a new this week published in the journal Nature, which examined over 200 heat waves since 2000. Scientists concluded that climate change intensified these heat waves, connecting them to what they term the 180 largest “carbon majors”—primarily high-polluting entities ranging from coal to cement manufacturers. Should this assertion be upheld in a legal setting, these businesses might face accountability for the expenses incurred by these heat waves. The paper states, “While this research seeks to address scientific deficiencies, its findings also bridge gaps in evidence.”
This investigation coincides with a surge of legal actions aiming to compel energy corporations to cover the expenses associated with climate change. Over the past decade, over 80 global cases have been initiated to force polluting firms to bear the financial burden of climate impacts, as per a from the Grantham Institute at the London School of Economics. Last year alone saw the filing of eleven such cases. (My colleague Simmone Shah last month.)
Legal challenges can occasionally function merely as communication tools, intended to influence public perception even with a low probability of courtroom success. However, when considered together, litigation directed at corporations holds the power to genuinely influence legal frameworks. A German court earlier this year determined that companies could be held accountable for climate-related harm stemming from their operations. Within the U.S., cases in Hawaii, Minnesota, and Colorado have secured substantial procedural victories. Despite these lawsuits addressing unsettled legal issues—such as whether companies should be held responsible for their products or how to assign culpability for specific climate occurrences to particular firms—the energy sector is treating them with gravity. Although industry executives publicly skirt the subject, privately they concede that litigation poses a considerable threat to their business’s future. Regardless of the calculation, covering the expenses of climate-related incidents could readily deplete the financial resources of even the biggest corporations.
Corporate financial statements provide insight into how fossil fuel entities perceive these legal challenges. In a last year, Chevron characterized the lawsuits as “legally and factually without merit,” yet conceded that “given the unpredictability of litigation, there is no guarantee that these cases will not significantly impact the company’s financial performance.” ConocoPhillips offered a comparable assessment in its 2024 , labeling them an “unsuitable mechanism for tackling the complexities linked to climate change,” while stating that “their final resolution and effect on us cannot be foreseen with certainty.” Analogous declarations are observable across numerous companies.
Attempting to forecast the ultimate resolution of these events would be unwise. In the United States, the Trump Administration initiated legal action to prevent states from pursuing such lawsuits, which aim to recover climate-related damages from energy firms. It is plausible that federal appeals courts might favor the industry regarding such an unproven legal premise. However, these legal battles span the globe, mirroring the reach of energy corporations. A single receptive jurisdiction could dramatically alter the existing situation.
Victories in these legal proceedings would be celebrated by many within the climate movement who aim to impede the fossil fuel industry. Concurrently, those advocating for the industry to leverage its financial assets for investment in clean technologies may need to re-evaluate their strategy if climate litigation weakens the financial standing of fossil fuel companies. For many observers, these lawsuits bring forth profound questions concerning accountability, both corporate and broader. Yet, irrespective of one’s ideological viewpoint, the trajectory and future of oil and gas corporations remain a pivotal consideration for all initiatives addressing climate change. Therefore, it is crucial to regard these cases with due seriousness.
