Tesla privately warned the UK government that weakening electric vehicle rules would hit battery car sales and risk the country missing its carbon dioxide targets, according to newly revealed documents.

 

The US electric carmaker, run by Elon Musk, also called for “support for the used-car market”, according to submissions to a government consultation earlier this year obtained by the Fast Charge, a newsletter covering electric cars.

 

The Labour government in April worried some electric carmakers by weakening rules, known as the zero-emission vehicle (ZEV) mandate. The mandate forces increased sales of EVs each year, but new loopholes allowed carmakers to sell more petrol and diesel cars.
