Data extracted in November 2025

Planned article update: 16 February 2026

Highlights

In Q2 2025, EU economy greenhouse gas emissions were estimated at 772 million tonnes of CO2-equivalents, a 0.4% decrease compared with the same quarter of 2024.

Greenhouse gas emissions - All NACE activities plus households

This article is about quarterly emissions of greenhouse gases (GHG emissions) in the European Union (EU) classified by emitting economic activities (industries and households). The GHGs comprise carbon dioxide (CO₂), nitrous oxide (N₂O), methane (CH₄) and fluorinated gases (hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulphur hexafluoride (SF₆) and natrium trifluoride (NF₃). Eurostat records and publishes these in air emissions accounts (AEA), one of the modules in the European environmental economic accounts (for which the legal basis is Regulation (EU) No 691/2011). AEA are suited for integrated environmental-economic analyses such as calculating emission intensities or 'footprints'.

Greenhouse gas emissions

In Q2 2025, EU economy greenhouse gas emissions were estimated at 772 million tonnes of CO₂-equivalents, a 0.4% decrease compared with the same quarter of 2024 (775 million tonnes of CO₂ equivalents).

Emissions by economic activity

Greenhouse gas emissions in Q2 2025 decreased by 0.4% compared with the same quarter of the previous year while the EU's gross domestic product (GDP) registered a 1.3% increase.

In Q2 2025 the economic sectors contributing the most to the total greenhouse gas emissions were manufacturing (22.5%), households (18.4%) and transportation and storage (16.0%). The grouping 'other' is responsible for around one-third of the total emissions and is composed of the remaining sectors of the economy: agriculture, forestry and fishing; mining and quarrying; construction; water supply, sewerage, waste management and services (except transportation and storage) (see Figure 1).

Compared with Q2 2024, emissions decreased in 4 out of 9 economic sectors. The economic sectors responsible for the largest year-on-year decreases were electricity, gas, steam and air conditioning supply (-2.9%), agriculture, forestry and fishing (-1.6%), manufacturing (-0.4%) and transportation and storage (-0.4%). Households increased their emissions by 1.0%. (see Figure 2).

Greenhouse gas emissions across EU countries

In the second quarter of 2025, year-on-year increases in greenhouse gas emissions were estimated for 14 EU countries, decreases were estimated for 12 EU countries and Estonia registered stable figures. The largest reductions in greenhouse gases were estimated for Slovenia (-8.6%), the Netherlands (-5.9%) and Finland (-4.2%). Out of the 12 EU countries that registered decreases in greenhouse gas emissions, 3 also recorded a decline in their GDP (Finland, Germany and Luxembourg). The other 9 EU countries (Austria, Cyprus, Denmark, France, Italy, the Netherlands, Romania, Slovenia and Sweden) were estimated to have decreased emissions while growing their GDP.

Data sources

Quarterly data are estimated by Eurostat applying the methods described in the methodological note on Eurostat's Estimates of Quarterly Greenhouse Gas Emissions Accounts. The quarterly estimates are based on sub-annual activity data and annual air emissions accounts (AEA).

The figures in this article are non-seasonally adjusted. Progress is measured against the same quarter in the previous year, to avoid the interference of seasonal effects. Seasonally adjusted data have also been produced for the first time and are available in Eurostat’s online database. These adjusted series enable quarter-on-quarter change analyses.

In AEA, the emissions data are organised by economic activity, using the NACE classification. This arrangement makes it possible to have an integrated environmental-economic analysis to supplement national accounts. The scope encompasses production by all businesses resident in the country, including those operating ships, aircraft and other transportation equipment in other countries.

Air emissions accounts also include households as consumers. Their emissions are accounted for whenever household consumption is directly responsible for environmental pressures. For example, emissions from a privately owned car are accounted under households, whereas cars owned by transport businesses (such as taxis) are accounted under transportation and storage.

The following groupings of economic activities are used in this article:

agriculture, forestry and fishing — NACE Rev. 2 Section A;
mining and quarrying — NACE Rev. 2 Section B;
manufacturing — NACE Rev. 2 Section C;
electricity, gas, steam and air conditioning supply — NACE Rev. 2 Section D;
water supply, sewerage, waste management — NACE Rev. 2 Section E;
construction - NACE Rev. 2 Section F;
transportation and storage — NACE Rev. 2 Section H;
services (except transportation and storage) — NACE Rev. 2 Sections G to U minus H;
households — households as consumers;
other - sum of agriculture, forestry and fishing; mining and quarrying; construction; water supply, sewerage, waste management and services (except transportation and storage)

In addition, Eurostat disseminates greenhouse gas emissions classified by technical processes. These are recorded in GHG emission inventories, including data for international climate policies. Furthermore, Eurostat estimates and disseminates 'footprints' which are greenhouse gas emissions classified by final products that are demanded by households or government, or that are invested in or exported.

Each greenhouse gas has a different capacity to cause global warming, depending on its radiative properties, molecular weight and the length of time it remains in the atmosphere. The global warming potential (GWP) of each gas is defined in relation to a given weight of carbon dioxide for a set time period (for the purpose of the Kyoto Protocol a period of 100 years). GWPs are used to convert emissions of greenhouse gases to a relative measure (known as carbon dioxide equivalents: CO₂-equivalents). The weighting factors currently used are as defined in the IPCC Fifth Assessment Report: carbon dioxide = 1, methane = 28, nitrous oxide = 265 and sulphur hexafluoride = 23 500; hydrofluorocarbons and perfluorocarbons comprise a large number of different gases that have different GWPs.

Context

The data obtained from air emissions accounts may subsequently feed into political decision-making, underpinning policies that target both continued economic growth and sustainable development, including the European Commission's European Green Deal. Air emissions accounts measure the interplay between the economy and the environment with respect to air emissions, in order to assess whether current production and consumption activities are on a sustainable path of development. Measuring sustainable development is a complex undertaking as it has to incorporate economic, social and environmental indicators.
