"Carbon dioxide (CO2) emissions from fossil fuels and cement will rise around 1.1% in 2025, reaching a record 38.1bn tonnes of CO2 (GtCO2), according to the latest figures from the Global Carbon Project.
However, falling land-use emissions means that global CO2 emissions in 2025 will remain relatively unchanged compared to 2024 levels.
The 20th edition of the annual Global Carbon Budget report, published today, also finds that the land carbon sink – the portion of human-caused CO2 emissions absorbed by plants and soils – appears to have recovered to its pre-El Niño strength after two unusually weak years.
However, research published alongside the report by the same team also suggests that climate change has caused a long-term decline in land and ocean carbon sinks, with sinks being about 15% weaker over the past decade than they would have been without climate impacts."
