Jeff Bezos is committing to move Amazon.com Inc. (NASDAQ: AMZN) to net-zero carbon emissions by 2040 as part of a broader private-sector climate change initiative — and he says the company’s Arlington headquarters will play a major part in meeting that goal. In a rare local public appearance, the Amazon CEO stopped by the National Press Club in D.C. Thursday to unveil his new environmental plans. The move comes on the eve of the launch of the global climate strike, an international initiative designed to drive home the urgency of climate action.
