Tesla privately cautioned the UK government that any dilution of electric vehicle regulations would negatively affect EV sales and jeopardize the nation's carbon reduction goals, according to documents revealed on December 3, 2025. The electric automaker argued it was "essential" for the government to avoid introducing new loopholes, known as "flexibilities," to the zero-emission vehicle (ZEV) mandate. In submissions to a government consultation, Tesla stated that such changes "will suppress battery electric vehicle (BEV) supply, carry a significant emissions impact and risk the UK missing its carbon budgets." The company also advocated for greater support for the used-car market to further encourage the transition to electric vehicles. This lobbying effort highlights Tesla's concern that weakening mandates could undermine investment and demand in a critical European market.
