Time is no longer running out to act on climate change; it’s up, and the global economy is at a crossroads. But, if the world acts now to rapidly achieve net-zero emissions by mid-century, the transformation of the economy would set the world up for stronger economic growth by 2070.

Such a transformation could increase the size of the world economy by $43 trillion in net present value terms from 2021-2070.  We have the technologies, business models, and policy approaches today to deliver rapid decarbonization and limit global warming to as close to 1.5°C by century’s end. 

We cannot afford to waste another year, another month, debating the merits of doing something versus doing nothing. As leaders, every choice, every day is a chance to speed the realization of that vision.
