Ambitious action to meet the Paris Agreement, which includes a target to keep global warming well below 2°C, could boost the global economy by $19 trillion, Bloomberg News reports.

A new report from the International Renewable Energy Agency (IRENA) finds that heavy investments in renewable power and energy efficiency would increase the global economy by about 0.8 percent by 2050. These gains don’t come for free, however: to reach these goals, the share of renewable energy needs to increase from 15% to 65% of the primary energy supply by 2050 — an effort that will require $145 trillion in low-carbon investment by the middle of the century
