The time is now for decisive action, and the United States is boldly tackling the climate challenge. In 2021, we rejoined the Paris Agreement, set an ambitious Nationally Determined Contribution to reduce net greenhouse gas emissions by 50-52% in 2030, launched the Global Methane Pledge, and have undertaken additional concrete actions to advance climate action domestically and internationally. These investments are critical to immediately accelerate our emissions reductions. This 2021 Long-Term Strategy represents the next step: it lays out how the United States can reach its ultimate goal of net-zero emissions no later than 2050. Achieving net-zero emissions is how weâand our fellow nations around the globeâwill keep a 1.5Â°C limit on global temperature rise within reach and prevent unacceptable climate change impacts and risks.
