"$26 trillion by 2030.

That, according to the most authoritative research to date, is the amount of money humanity could save through a global shift to sustainable development.

It’s a lot of money. Before you break your brain trying to imagine it, just pause to make a note that it’s a positive sum (uh, extremely positive), not negative. Net savings, not costs.

That might come as a surprise since decades of conservative and fossil fuel propaganda have made it conventional wisdom that cleaning up our act is expensive — that it costs more than the status quo. It is the argument hauled out against every single pollution regulation."
