CO2 emissions at record high in 2023

12/05/2023 - Global carbon dioxide emissions from fossil fuel use will amount to 36.8 billion tonnes in 2023, a record high that exceeds the 2022 level by 1.1% - the latest Global Carbon Budget report finds. This is a long way off the significant reductions that are needed to reach the Paris Agreement climate goals.

The report states that if current levels of carbon dioxide emissions continue, the remaining carbon budget for a 50% chance of limiting warming to 1.5°C could be used up in seven years, and of limiting warming to 1.7°C in 15 years.

Regionally, the trends varied greatly: Whereas fossil emissions increased in India and China (+8.2% and + 4.0%), they fell in Europe and the United States (-7.4% and -3.0%) and decreased marginally in the rest of the world (-0.4%). The authors attribute the decline in Europe to the expansion of renewables and the effects of the energy crisis. Meanwhile, they attribute the growth in China partly to delayed recovery from the effects of the Covid-19 lockdowns.

The time left to reach the climate goals of the Paris Agreement is running out fast, the report concludes.

The Global Carbon Project (GCP) which publishes the Global Carbon Budget report annually is an association of international scientists with a large German contribution. The Potsdam Institute for Climate Impact research (PIK) provided simulations to the study using LPJmL5, a global vegetation and carbon model. Together with the simulation results of 19 other models, they form the basis for estimating the carbon sink and emissions from land use change.
