The European Union has set fleet-wide car emissions targets of 93.6g CO2/km for 2025-2029, 49.5g CO2/km for 2030-2034, and zero from 2035 onwards. The United States under the Trump administration has moved in the opposite direction, loosening its rules to permit fleet averages of roughly 157g CO2/km. Commenters highlight the growing transatlantic divide on vehicle climate policy.
