Lima: last minute agreement to reduce CO₂ emissions

On Sunday December 14, 2014, the 20^th UN climate conference ended in Lima, Peru.

Further to two weeks of negotiations and an extension of more than 30 hours, the 195 countries attending the conference reached an agreement: in 2015, each country will have to define its own contribution to the global effort to reduce greenhouse gas emissions. In the current situation, the growth of global emissions would lead to a global warming of 3 to 4°C. Commitments will have to enable a global decrease in emissions of 40% to 70% by 2050, in the aim of limiting to 2°C the increase in the planet temperature by the end of the century.

The agreement entered into is a first step towards the awaited Paris climate conference which will be held from November 30 to December 11, 2015. The objective of the conference will be to sign a comprehensive global agreement to come into force in 2020, committing industrialized countries and developing countries in a joint action against global warming.
