No trend reversal in sight! After reaching a record high in 2024, CO₂ concentrations in the Earth’s atmosphere will continue to increase in 2025. International researchers assume that global greenhouse gas emissions will increase compared to the previous year.
Scientists led by Pierre Friedlingstein from the University of Exeter (United Kingdom) estimate an increase to 425.7 ppm (particles per million). In 2024 the concentration will reach The record value was achieved at 423.9 ppm.
38.1 billion tons of CO2 emissions
If emissions continue at this rate, the remaining CO2 budget needed to meet the 1.5 degree target will be reduced Paris Convention must be exhausted before 2030. This was revealed in the Global Carbon Budget 2025 report written by researchers in the journal “Earth System Science Data”. Friedlingstein and his colleagues from about 100 research institutions used the data material to calculate global developments in computer models.
► Therefore, global numbers are increasing CO2 emissions this year it will be 38.1 billion tonnes. In 2024 it will reach 37.8 billion tonnes.
There was growth for all fossil fuels: coal (+0.8 percent), petroleum (+1.0 percent) and natural gas (+1.3 percent). In United States of America Compared to the previous year, emissions are estimated to increase by 1.9 percent, in India by 1.4 percent, in China and in the European Union each by 0.4 percent.
The report also sees a positive trend
But researchers also see positive trends that prove that: Climate protection That Business not weakening: “35 countries were able to reduce their emissions while maintaining economic growth,” said co-author Corinne Le Quéré of the British University of East Anglia. This figure is twice as high in countries as it was ten years ago.
These countries include many European countries, but also AustraliaIsrael, New ZealandSouth Korea and Taiwan. However, the progress achieved is not enough to reduce global emissions in a sustainable manner considering increasing energy demand.
► Another positive trend is land use change, especially deforestation foresthave been greatly reduced through environmental policy measures. On the other hand, unfavorable trends result in the so-called sinking of the oceans and land: their absorption capacity decreases, mainly due to the impact of climate change.
