In March 2024, President Biden announced the strictest car emissions limits yet in the country in a bid to boost the take up of electric vehicles (EVs).

According to the Environmental Protection Agency, the regulation will prevent 7bn tonnes of CO2 from entering the atmosphere over 30 years.

The measures include a target of 56% for all new vehicles sold in the US to be electric by 2032. EVs have no exhaust emissions but have a big ecological footprint owing to the precious minerals used in batteries.
