In the first quarter of 2024, the EU economy greenhouse gas emissions were estimated at 894 million tonnes of CO2-equivalents (CO2-eq), a 4.0% decrease compared with the same quarter of 2023 (931 million tonnes of CO2-eq). The EU’s gross domestic product (GDP) remained stable, registering just a small increase (0.3% in the first quarter of 2024, compared with the same quarter of 2023). This information comes from data on quarterly estimates for 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 a handful of findings from the more detailed Statistics Explained article on quarterly greenhouse gas emissions. Source datasets: env_ac_aigg_q, namq_10_gdp In the first quarter of 2024, the economic sectors responsible for the largest reductions compared with the first quarter of 2023 were electricity and gas supply (-12.6%) and households (-4.4%). Greenhouse gas emissions down in 20 EU countries In the first quarter of 2024, greenhouse gas emissions are estimated to have decreased in 20 EU countries, when compared with the same quarter of 2023. The largest reductions in greenhouse gases are estimated for Bulgaria (-15.2%), Germany (-6.7%) and Belgium (-6.0%). Out of the 20 EU members that are estimated to have decreased their emissions, 8 also recorded a decline in their GDP (Czechia, Germany, Estonia, Ireland, Luxembourg, the Netherlands, Austria and Finland). The other 12 EU countries (Belgium, Bulgaria, Denmark, Spain, France, Italy, Hungary, Poland, Portugal, Slovakia, Sweden and Croatia) are estimated to have managed to decrease emissions while growing their GDP.
