The figures are based on quarterly estimates of greenhouse gas emissions by economic activity published by Eurostat. These data complement quarterly macroeconomic indicators such as GDP and employment and provide a basis for assessing the relationship between economic activity and emissions trends.
At sector level, households recorded the largest increase in greenhouse gas emissions in the third quarter of 2025, with a rise of 3.6% compared with the previous quarter. Emissions from manufacturing increased by 1.4%. The electricity, gas, steam and air conditioning supply sector was the only segment to record a decline, with emissions decreasing by 0.8%.
Compared with the third quarter of 2024, seasonally adjusted greenhouse gas emissions remained unchanged. Over the same period, seasonally and calendar adjusted GDP increased by 1.6%.
At Member State level, greenhouse gas emissions increased in 17 EU countries in the third quarter of 2025 compared with the previous quarter, while 10 countries recorded a decrease. The largest reductions were observed in Estonia, with a decline of 17.4%, followed by Slovenia at 5.7% and Cyprus at 5.2%.
Among the 10 Member States that reduced emissions, Lithuania was the only country to report a simultaneous decline in GDP. The remaining nine countries – Bulgaria, Estonia, Croatia, Cyprus, Latvia, Portugal, Romania and Slovenia – reduced emissions while maintaining or increasing their GDP.
