Sustainability
In addition to climate change, the current war in Ukraine has highlighted the urgency of a rapid transformation to post-fossility. This paper analyses the much-lamented negative climate policy and energy transition impacts of the Energy Charter Treaty (ECT) in international law, a treaty that serves as a basis for the compensation claims of fossil fuel companies in response to losses incurred because of climate policy measures. Methodologically, a legal interpretation is conducted, i.e., the ECT is interpreted grammatically and systematically.
