Paris, France.
He The world is far from reduced its greenhouse gas emissions are sufficient to achieve the goals of the Paris Agreement about him Climate change from 2015.
However, they did Have made real progress since 2015: Although climate developments are still threatening, they have improved and the growth of renewable energies is faster than expected.
0.6°C to 1°C less warming
If that Paris Agreement at COP21According to the International Energy Agency (IEA), nations’ economic policies meant that by 2100 the world would reach 3.5°C of global warming compared to the pre-industrial era.
- This level implied chain climate catastrophes (uninhabitable regions due to extreme heat and drought, melting of the poles, glaciers and permafrost).
But eight years later, this is what countries’ current commitments represent World on a warming trajectory According to UN calculations released ahead of COP28, the increase has risen from 2.5°C to 2.9°C over the century.
- And according to the IEA, the planned global energy policy even corresponds to a trend of +2.4 °C by the year 2100.
Peak emissions before 2025
Annual greenhouse gas emissions since 2015 have increased by around 9%, according to the UN. This is less than previously expected Paris Agreement.
The rate of increase slowed noticeably until it reached its peak global emissions could be reached in 2024or even in 2023, according to current estimates from the Institute for Climate Analysis.
This is in line with the scenario recommended by the IPCC, the climate experts mandated by the United Nations, for achieving the Paris goals.
- Before the Paris AgreementThe IEA predicted that energy sector emissions (more than 80% of CO2 emitted by human activities) would reach 43 billion tonnes (Gt) in 2030, but the agency has just revised this figure downwards to 35 Gt.
“This difference of 7.5 Gt represents the cumulative emissions of the energy sector in the United States and Europe,” the IEA said in the latest update of its report. “Road to net zero.”
