Annex I countries

Annex I countries refer to a group of mostly developed nations that participated in the UN Framework Convention on Climate Change (UNFCCC), originally agreed upon in 1992. These countries are primarily responsible for historical greenhouse gas emissions and committed to taking the lead in reducing emissions, providing financial support to developing countries, and sharing clean technology. The list includes nations like the United States, European Union countries, Japan, and Australia. The designation helps differentiate responsibilities in international climate agreements, emphasizing that developed countries should take more robust action to address climate change due to their longer history of emissions.
