The Biden administration has committed to reducing US greenhouse gas emissions by 61-66% below 2005 levels by 2035, aiming for net zero emissions by 2050. The EU is likely to miss its climate target deadline, and developing countries express disappointment over financial support. The US Climate Alliance has set a complementary target of a 60% emissions cut by 2035, while criticism arises regarding the federal plan's lack of fossil fuel phase-out deadlines. Some view the new NDC as a positive step, while others see it as insufficient.
