According to Financial Times, Michael Regan, the administrator of the US Environmental Protection Agency (EPA) said that this effort is "the most ambitious pollution standard ever for cars and trucks." The new measures aim to increase the share of EVs on the US market, which was sitting at just 7% last year in the US.

Despite severely cutting on the allowed emissions for manufacturers' new models, the regulation would apparently go into force from 2027 until 2032.

Ford, General Motors and Stellantis have all promised to make 40-50% of their EV offerings all electric for the US market by 2030, a target for which they invested billions of dollars into research and development and new factories.

However, besides the supply chain which will have to provide the necessary materials for the move, there is also a question of can American carmakers deliver reasonably-priced EVs to compete with their fossil-counterparts?

Whether this will be achieved or not, there are experts who believe that enforcing such a law is necessary and carmakers will need to adapt.

"If you’re serious about dealing with climate change problems, then you need to address the transportation sector", said Howard Learner, executive director of the Environmental Law & Policy Center.

Tesla is one of the few American EV manufacturers who sells only battery-powered cars, which means that the proposed law works completely with their business model and fully benefits them.
