The world’s biggest lithium-ion battery maker, Tesla Motors, has been forced to shut one of its factories in China because of concerns over carbon emissions

Tesla reportedly told employees on Sunday to stay home to comply with the city’s covid restrictions. The city will remain closed for another day as the city deals with strict lockdown measures.

Tesla will resume production at the Shanghai plant on Monday, April 4th. Some stay-at-home orders are expected to end. There’s no word on when the city plans to lift them.

Tesla first shuttered its plant on March 28th, the start of the city’s two-stage lockdown. As of Monday, the factory will have been closed for one week. Tesla previously closed the Shanghai factory for two days in mid-March due to a rise in covid-19 cases.
