Some of the world’s biggest companies and deepest-pocketed investors are lining up trillions of dollars to finance a shift away from fossil fuels. Assets in investment funds focused partly on the environment reached almost $2 trillion globally in the first quarter, more than tripling in three years. Investors are putting $3 billion a day into these funds. More than $5 billion worth of bonds and loans designed to fund green initiatives are now issued every day. The two biggest U.S. banks pledged $4 trillion in climate-oriented financing over the next decade.

“We’ve reached the tipping point and beyond,” said James Chapman, chief financial officer at Dominion Energy Inc., D 1.28% one of the country’s biggest utilities. Dominion, which has begun issuing green bonds, is planning to spend $26 billion or more on clean energy such as wind and solar in the next five years.
