India’s quest for energy independence has led to some environmentally positive changes, like conversion of auto engines, but also some environmentally negative changes, like the expansion of India’s offshore oil and gas wells. The role of these wells as a pollutant arises certainly in the case of a spill, but also as various new international regulations related to climate change impacts come into effect. The Biodiversity Beyond National Jurisdiction (BBNJ/High Seas) Treaty and the International Tribunal for the Law of the Sea (ITLOS) Advisory Opinion on Climate Change both contain language related to higher standards for environmental impact assessments that consider cumulative emissions and transboundary harms.
