The asset manager could vote against directors if a company has not provided "a credible plan to transition its business model to a low-carbon economy." In other cases, BlackRock is open to supporting shareholder proposals that will force the company to make changes, if it feels "attention to the issue could be accelerated." Over the past three years, BlackRock has increased pressure on companies to take more aggressive steps to lower their environmental impact. Last year it joined Climate Action 100+, an investor group with $52 trillion in assets, which is working to coordinate investor attempts at tackling the climate challenge. BlackRock's activism has coincided with eight of the world's largest economies setting targets to zero out net emissions. That number will rise to nine if U.S. President Joe Biden fulfills his campaign promise. Last year, BlackRock voted against the management of 69 companies out of a group of 440 it classifies as carbon intensive.
