ClimateChange | United Nations

Climate change is a global emergency that goes beyond national borders. It is an issue that requires coordinated solutions at all levels and international cooperation to help countries move toward a low-carbon economy. To tackle climate change and its negative impacts, 196 countries adopted the Paris Agreement at the COP21 in Paris on 12 December 2015. Entered into force less than a year later, the deal aims to substantially reduce global greenhouse gas emissions and to limit the global temperature increase in this century to 2 degrees Celsius while pursuing means to limit the increase even further to 1.5 degrees. The agreement includes commitments from all major emitting countries to cut their climate-altering pollution and to strengthen their commitments over time. It provides a pathway for developed nations to assist developing nations in their climate mitigation and adaptation efforts while creating a framework for the transparent monitoring and reporting of countries’ climate goals.
