Europe: CO₂ emissions by sector 2023| Statista

In 2023, the largest source of carbon dioxide throughout Europe was transportation, with the sector responsible for roughly 1.1 billion metric tons (GtCO₂). This accounted for around 30 percent of Europe's total CO₂ emissions that year. The power industry was the second-largest CO₂ polluter that year, with just under one GtCO₂ produced.

Declining emissions in the EU

CO₂ emissions in the EU decreased by roughly 30 percent between 2005 and 2023, to 2.5 GtCO₂. Much of the emission reductions in Europe can be attributed to the region's transition towards clean energy sources such as wind and solar, as well as a shift away from coal.

Europe's biggest CO₂ emitter

The largest CO₂ emitter in Europe is Germany, having produced almost 600 MtCO₂ in 2023. This is considerably more than other European countries such as Italy, France, and Poland. Germany is one of the 10 largest CO₂ emitters worldwide.

Supplementary notes

Figures were calculated by Statista using available data provided by the source.
Emissions include sources from fossil fuel use (combustion, flaring), industrial processes (cement, steel, chemicals and urea) and product use. Short cycle carbon CO₂ is not included.
Regions based on IEA countries and regions.

Power Industry - Power and heat generation plants (public & autoproducers) Industrial combustion - Combustion for industrial manufacturing Buildings – Small scale non-industrial stationary combustion Transport – Mobile combustion (road & rail & ship & aviation) Agriculture Agricultural soils, crop residues burning, enteric fermentation, manure management, indirect N2O emissions from agriculture Fuel exploitation - Production, transformation and refining of fuels Processes - Industrial processes (e.g. emissions from the production of cement, iron and steel, aluminum, chemicals, solvents, etc.) Waste - Solid waste disposal and waste water treatment
