In 2021, the U.N. Intergovernmental Panel on Climate Change (IPCC) determined a carbon budget of 500 billion metric tons would keep global warming below 1.5 degrees Celsius until mid-2032.

The annual Global Carbon Budget projects fossil carbon dioxide (CO 2 emissions of 36.8 billion tonnes in 2023, up 1.1% from 2022.. Fossil CO 2 emissions are falling in some regions, including ...

The central estimate of the remaining carbon budget for 1.5°C is 130 billion tons of carbon dioxide (CO2) (from the beginning of 2025). This would be exhausted in a little more than three years at ...

Without rapid carbon dioxide emission reductions, the world has a 50% chance of locking in 1.5°C of warming before 2030, according to a study led by Imperial College London researchers.

The study by researchers from the University of Illinois Urbana-Champaign and the World Bank shows that climate uncertainty ...

Global carbon emissions from fossil fuels have reached a record high in 2024, according to new research by the Global Carbon Project science team.. The 2024 Global Carbon Budget projects fossil carbon ...

The 2024 Global Carbon Budget projects fossil carbon dioxide ... primarily due to the uncertainty of the additional warming coming from non-CO 2 agents (e.g., CH 4, N 2 O, aerosols).

The model’s smaller carbon budget imbalance reduces uncertainty and makes it a better tool than the ENSO or GCP models for verifying reported carbon emissions. At a five-year timespan the new model ...

Current emissions trajectories mean there is a 50 per cent chance global warming will exceed 1.5C consistently in about six years, researchers from the Global Carbon Budget team have warned after ...

Our latest annual stocktake shows the world is on track to reach a new record: 37.4 billion tonnes of CO emitted from fossil fuels in 2024. This is an increase of 0.8% from the previous year.
