The two Indian tycoons are stepping in at a time when many developed countries are scrambling for alternative sources of fuels as they try to back away from Russian supplies. This month, the Group of Seven most-industrialized nations pledged to ban imports of Russian oil. The disruption has also brought the focus back on the need for more coal, the dirtiest fossil the world has vowed to phase out to cut emissions.
Though Adani, 59, and Ambani, 65, have unveiled a combined $142 billion in green investments over the next few decades in a pivot away from coal and oil -- the bedrock of their empires -- they are also finding it hard to kick the fossil-fuel habit as the conflict stokes demand. Global coal demand is expected to rise to a record level in 2022 and stay there through 2024, according to the International Energy Agency.
