EU economy greenhouse gas emissions: +0.9% in Q4 2025

The EU economy's seasonally adjusted greenhouse gas emissions in the fourth quarter of 2025 were estimated at 839 million tonnes of CO₂-equivalents (CO₂-eq), a 0.9% increase compared with the third quarter of 2025 (832 million tonnes of CO₂-eq). At the same time, the EU's gross domestic product (GDP) increased by 0.2% in the fourth quarter of 2025, compared with the previous quarter of 2025.

This information comes from data on seasonally adjusted quarterly estimates of greenhouse gas emissions by economic activity published by Eurostat today. Quarterly estimates of greenhouse gas emissions complement quarterly socio-economic data, such as GDP or employment.

This article presents the key findings from the more detailed Statistics Explained article on quarterly greenhouse gas emissions.

The economic sectors with the largest increases in greenhouse gas emissions were electricity, gas, steam and air conditioning supply (+7.2%), transportation and storage (+1.3%) and mining and quarrying (+0.9%), while households (-2.0%) and manufacturing (-0.1%) recorded a decrease.

Greenhouse gas emissions decreased in 7 EU countries

In the fourth quarter of 2025, seasonally adjusted greenhouse gas emissions increased in 19 EU countries and decreased in 7 countries, while they were stable in Germany, compared with the third quarter of 2025.
The largest reductions in greenhouse gases were estimated for Finland (-3.2%), Malta (-2.0%) and Czechia (-0.6%).

All of the 7 EU countries that had estimated decreases in greenhouse gas emissions (Bulgaria, Czechia, Spain, Lithuania, Malta, Slovakia and Finland) recorded an increase in GDP.
