The green economy—the business lines of global listed companies that generate revenue from climate solutions — now boasts a record high market value of $10 trillion. The increase occurred as revenue tied to environmental products and services climbed to $5.5 trillion last year, expanding at its fastest pace since 2022, according to a report published Wednesday by London Stock Exchange Group. Investors have rewarded that growth: Companies deriving over 20% of their income from green activities have been outperforming the broader equity market, LSEG said. The S&P Global Clean Energy Transition Index has surged more than 80% since the end of 2024, more than double the return of the S&P 500.
