COP21 – The Climate Deal

The international political response to climate change began at the Rio Earth Summit in 1992, where the United Nations Framework Convention on Climate Change was adopted. The Rio Convention set out to limit average global temperature increases by reducing greenhouse gases. The annual Conference of the Parties (COP) reviews the Convention's implementation.

In 2015, COP21 aimed to achieve a new universal, legally binding agreement on climate change with the objective of keeping global warming below 2°C by the year 2100. A 2°C rise in global temperatures from pre-industrial levels is the highest increase the world can afford to prevent the worst effects of climate change. ADB welcomes the fact that the Paris agreement is closer to implementation following the decision by the USA and the People’s Republic of China - together responsible for 40% of the world's carbon emissions - to formally joined the Paris global climate agreement.
