The EU has promised to bring a law, binding on all member countries, to ensure it becomes “climate neutral” by 2050.
It was on the side-lines of recently concluded annual Madrid Climate talks.
EU with 28 member countries are together the third-largest emitter of greenhouse gases in the world after China and the United States.
The EU is now the first major emitter to agree to the 2050 climate neutrality target.
The EU also happens to be only one among major emitters to retain the 1990 baseline for emission cuts, originally mandated under the Kyoto Protocol for all developed countries.
Most other countries have shifted their baselines to 2005 or even later under the 2015 Paris Agreement.
The Kyoto Protocol required the rich and developed countries to provide finance and technology to the developing countries to help them fight climate change.
