For years, Tesla Inc. has hauled in revenue by selling credits to other carmakers that needed to offset sales of polluting vehicles to U.S. consumers. These sorts of transactions have largely been shrouded in secrecy — until now.
General Motors Co. and Fiat Chrysler Automobiles NV disclosed to the state of Delaware earlier this year that they reached agreements to buy federal greenhouse gas credits from Tesla. While the filings are light on detail, they haven’t been reported on previously. They also represent the first acknowledgments from carmakers that they’re turning to Tesla for help to comply with intensifying U.S. environmental regulations.
