Although climate change litigation is becoming more common, these examples do serve to illustrate how difficult it will be to succeed.
The complications inherent to climate change litigation occur in part due to the length of time between the extraction of oil and gas from the ground, performed by any given fossil fuel company, and the actual use of these fuels, which results in GHG emissions. This gap makes it hard to attribute any particular emissions to any particular fossil fuel company. The closest comparison and the area of law that is most often referred to when devising a strategy for climate change litigation, is tobacco litigation.[12]
Before tobacco litigation started to succeed, the arguments against it were similar: How can we closely connect the sale of tobacco to smoking and eventual negative health results for any individual person? How can we prove that it was this company’s cigarettes that led to the damages?[13]
Throughout the numerous attempts at tobacco litigation, plaintiffs eventually argued that tobacco companies knowingly misled and downplayed the negative health effects associated with smoking, thereby resulting in increased rates of cancer, heart disease, and other health problems.[14] These cases were ground-breaking and have paved the way for future litigation, including climate change litigation. Yet, we need to recognize that it is still significantly more difficult to connect a particular company’s fossil fuel extraction to any specific effect of climate change, in large part because the oil taken out of the ground is not as clearly branded as cigarette packages and cannot be as easily traced to individual users.
An interesting development for future climate change litigation are new studies (here and here) which have connected some of the effects of climate change to specific energy companies. These studies use models to determine which fossil fuel companies are responsible for the majority of climate change effects and divide the effects up by percentage. For example, one report found that only about 90 companies are responsible for nearly two-thirds of historical greenhouse gas emissions. This study, and others like it, will be helpful in determining the outcome of climate change lawsuits because they can help determine what damages each of these individual companies would be responsible for and could help to allocate liability according to their degrees of responsibility.[15]
