- The Kyoto Protocol is an international agreement linked to the United Nations Framework Convention on Climate Change that sets binding targets for reducing greenhouse gas emissions for industrialized countries.
- The goal is to reduce emissions of greenhouse gases to help prevent dangerous climate change. Countries agreed on average reductions of 5.2% from 1990 levels by 2012.
- The United States signed but later withdrew from the agreement in 2001, citing negative economic impacts. Many other countries have ratified it but it faces challenges in comprehensively addressing long-term climate change.
