Amazon CEO Jeff Bezos announced a massive new commitment to fight climate change called The Climate Pledge. He said Amazon will work to drastically reduce its carbon emissions with the ultimate goal of becoming carbon-neutral by 2040 — all part of an effort to avert some of the most catastrophic effects of climate change.
