"Published annually, the Global Carbon Budget report looks at emissions of CO2 into the earth's atmosphere via burning hydrocarbons, cement production and land use, such as deforestation. The report always relates the numbers to the thresholds set out in the the 2015 Paris Agreement, the accord which called for limiting warming to 2 Celsius at the top but ideally 1.5 C (3.6 degrees Fahrenheit or 2.7 degrees, respectively), compared to pre-industrial levels."
"Published while nations convene for COP30 climate talks in the Amazon in northern Brazil, the new report estimated a remaining allowance of 170 billion tons of CO2 to limit warming to 1.5C from pre-industrial levels. "This equates to four years of emissions at the current rate before the budget for 1.5C is exhausted, so that is impossible, essentially," said Pierre Friedlingstein of Britain's Exeter University, who led the team of scientists."
"But the international team of scientists that conducted the study found that CO2 emissions from fossil fuels will be 1.1% higher in 2025 than a year ago. With emissions from fossil fuels oil, gas and coal all set to go up, the overall figure is set to reach a record 38.1 billion tons of CO2. Despite the continued global expansion in the use of renewable energy, this has not been enough to offset the overall growth in energy demand ."
Global fossil fuel CO2 emissions are projected to reach a record 38.1 billion tons in 2025, a 1.1% increase from 2024. Oil, gas and coal use are all rising, and renewable energy expansion has not offset growing energy demand. The remaining carbon allowance to limit warming to 1.5°C is about 170 billion tons of CO2, equivalent to roughly four years of emissions at current rates. That remaining budget will be exhausted rapidly without immediate and deep reductions. COP30 is occurring in Belem, Brazil, amid these worsening emissions, and the United States is absent from the summit.
