According to a report, the reduction of CO2 emissions is largely insufficient to comply with the Paris Agreement | Climates Changes

A new study from the European Climate Foundation published Wednesday, March 3 in the journal Nature climate change presents the balance sheet of CO2 from fossil fuels since 2015.

Researchers from the Global Carbon Project and the University of East Anglia (UEA, United Kingdom) found that the average annual reductions of 0.15 billion tonnes of CO2 since 2015 they represent only 10 % of the 1-2 billion tons of reductions of CO2 needed every year globally to combat climate change. The 36 richest countries, including France, account for 35 % of global emissions of CO2 in 2019 but their emissions tend to decrease. Upper middle-income countries are responsible for 51 % of emissions CO2, of which 28 % from China only. The researchers also created an interactive graph to identify annual changes in emissions of CO2 depending on the country. In all, 64 countries have reduced their emissions by CO2 between 2016 and 2019.

According to the lead author, Corinne Le Quéré, countries’ efforts to reduce emissions of CO2 as the Paris Agreement is starting to bear fruit, but the shares are not yet on a large enough scale .

The authors report that with the Covid-19 crisis in 2020, emissions of CO2 globally they decreased by 7 % but it would not cause a lasting decrease if we did not move away from an economy based on fossil fuels. According to Corinne Le Quéré, it is in everyone’s interest to better rebuild our economy to accelerate the transition to clean energy .

The International Energy Agency (AHIA) also warned of a rebound in emissions by CO2 after the shock of the Covid-19 pandemic. In December, emissions would therefore have increased by 2 % compared to 2019. Fatih Birol, General Manager ofAHIA warns him the rebound in emissions from CO2 in the world at the end of last year represents a serious warning that we have not done enough to accelerate the transition to clean energy around the world .

This new study comes a few weeks after the report of theA which highlighted the insufficiency and ineffectiveness of measures to tackle the climate crisis. If these contributions determined at national level “, NDC in English, were applied, it would result in a decrease of only 1 % of global greenhouse gas emissions by 2030, while a reduction of 45 % is needed in order not to exceed the increase of 1.5 ° C.
