Ethical considerations aside, one of the other drivers of this is the origin of some of the money involved here. Most of the largest sovereign wealth funds globally are the result of money generated by resource extraction: Norway, Abu Dhabi, Kuwait, Saudi Arabia (directly and via Aramco), Qatar, etc. For these names, holding stocks that pose a climate risk is buying oil with oil dollars. Without intentional divestment of oil, coal, and other climate names, they are essentially levered long. Excluding these from their holdings is just prudent investment.
