Tesla released its first sustainability report April 15, in which the electric carmaker highlighted the positive effects it said its vehicles — and its production efforts — have had on the environment since purchasing its Fremont, Calif., factory in 2010.

Tesla on Jan. 30 reported fourth-quarter results that included better-than-expected sales — but its earnings supported CEO Elon Musk’s assertion from earlier this month that the electric-car maker has a “very difficult” road ahead in 2019.
