Introduction
According to the annual Global Carbon Budget report, global CO2 emissions from burning fossil fuels will reach a new record in 2025. The report, which examines human-induced CO2 emissions through the combustion of hydrocarbons, cement production, and land-use changes like deforestation, also warns that keeping global warming below 1.5°C may be “impossible.”
Key Findings
- Record-breaking emissions: The report projects that CO2 emissions from fossil fuels will increase by 1.1% in 2025 compared to the previous year, reaching a total of 38,100 million tonnes—a new record.
- Climate targets at risk: To limit global warming to 1.5°C above pre-industrial levels, the report states that no more than 170,000 million tonnes of additional CO2 can be added to the atmosphere. However, current emissions are on track to exceed this limit by four years if the rate continues.
- Lack of progress: The report highlights that despite the growing evidence that 2025 will be one of the hottest years ever recorded, countries’ climate plans fall short of addressing the issue adequately.
Emission Sources and Trends
The study indicates that emissions from oil, gas, and coal likely increased in 2023. In China, fossil fuel emissions remained stable overall, with coal use slightly decreasing. Meanwhile, the United States saw a rise in carbon emissions due to increased reliance on coal amidst rising natural gas prices.
In contrast, India’s early monsoon and the growth of renewable energy sources helped limit CO2 emissions compared to previous years. The report also notes that 35 countries managed to reduce their emissions without hindering economic growth, which is double the number a decade ago.
Land Use and Forestation
The report acknowledges that reduced deforestation and wildfires in South America, partly due to the end of the extremely dry El Niño conditions in 2023-2024, contributed to a decrease in emissions caused by land use changes.
Key Questions and Answers
- What does the report predict for 2025? Global CO2 emissions from human activities, primarily fossil fuel combustion, are projected to reach a new record in 2025.
- Why is it challenging to meet climate targets? Current emission trends suggest that the additional CO2 limit set for 1.5°C global warming will be surpassed in four years at the current rate.
- Which countries are making progress in reducing emissions? Despite overall challenges, 35 countries have successfully decreased their emissions without compromising economic growth.
