The Paris Agreement is an international treaty adopted in 2015 under the United Nations Framework Convention on Climate Change (UNFCCC). Its goal is to limit global warming to well below 2°C, with an aim of keeping it below 1.5°C above pre-industrial levels. The agreement commits countries to set national targets for reducing greenhouse gas emissions (known as Nationally Determined Contributions, or NDCs) and to regularly review and strengthen their commitments over time. It also emphasizes climate adaptation, financial support for developing countries, and a long-term vision of a carbon-neutral global economy.
