One of the major challenges for the future of our climate lies in limiting global warming of the planet, which must remain well below 2°C, compared to the pre-industrial era. The goal of 1.5°C was set out in the Paris agreement signed at COP21 in 2015, based on studies by the IPCC (Intergovernmental Panel on Climate Change). To meet this goal, greenhouse gas emissions must level out between now and 2025; with a reduction in emissions of over 40% between now and 2030.
At COP27, the European Union does not envisage any retreat to be possible, but, on the contrary, encourages that this trajectory be maintained. Only, there is no mention of any new way of reinforcing the actions. A disappointment for the EU, as the policies currently in place are leading more towards global warming of +2.8°C.
We need to drastically reduce emissions now – and this is an issue this COP did not address", deplored the UN Secretary-General, Antonio Guterres.
As the US president, Joe Biden, re-emphasized on his visit to COP27, the remainder of this target could be met by taking action on methane emissions. The reduction in this gas, responsible for 25% of the rise in temperatures since the industrial era, is attainable.
The "Global Methane Pledge" signed at the COP26 in Glasgow by 103 countries, which have since been joined by fifty or so other countries with the aim of reducing their methane emissions by 30% by 2030.
The IPCC has estimated that a 45% reduction in methane emissions by 2030 would make it possible to avoid 0.3°C of rise in temperatures by 2040, and 0.8°C by the end of the century.

Methane has a global warming potential that is 84 times higher than that of CO2 over a 20-year period.
