This week, oil giant ExxonMobil pledged $3 billion to the development of a carbon capture and storage business over the next five years — in a bid to manage its business risks associated with climate change. CEO Darren Woods noted in the company’s press release: “We are focused on proprietary projects and commercial partnerships that will have a demonstrably positive impact on our own emissions as well as those from the industrial, power generation and commercial transportation sectors, which together account for 80 percent of global CO2 emissions.”
