Global Carbon Budget 2021CO2 emissions rebound towards pre-COVID levels

Global fossil CO2 emissions in 2021 are set to rebound 4.9% after a record 5.4% drop in 2020.This follows a decade of strong and growing energy decarbonisation which reduced the growth of emissions.

CO2emissions

cuts of 1.4 billion tonnes are needed

each year on average to reach net zero by 2050

Coal and gas use grow more in 2021 than they fell in 2020.Oil use remains below 2019 levels.

The level of CO2 continues to increase in the atmosphere, causing climate change.Emissions from deforestation and other land-use change remain high, partly offset by removals from regrowth of forest and soil recovery.
