General Motors Maps Its Zero-Emission Future

Of the 10 million vehicles General Motors sold worldwide last year, only a fraction—about 14,000—were powered solely by electricity. The rest were fueled by gas and diesel, with tailpipes that pumped carbon emissions into the air. Now, the automaker is making a commitment to completely phase out those internal combustion engines.

“General Motors believes in an all-electric future,” said Mark Reuss, GM's head of product development, at a media event on Monday where the company announced plans to release two new electric vehicle models in the next 18 months—and a total of 20 by 2023.
