The "GHG EMISSIONS OF ALL WORLD COUNTRIES – 2025 Report", published by the European Commission in cooperation with the International Energy Agency (IEA), provides an independent quantitative overview of global greenhouse gas (GHG) emissions and includes detailed data for individual countries. Slovakia is one of the 27 EU Member States (EU27) for which these data are processed. The information is drawn from an extensive database EDGAR (Emissions Database for Global Atmospheric Research), which offers time series of greenhouse gas emissions for all countries and anthropogenic sectors from 1970 to 2024.
Total emissions and their composition in 2024 According to the latest data from EDGAR, total greenhouse gas emissions in Slovakia in 2024 reached 39,001 Mt CO2eq/yearThe breakdown of these emissions by individual greenhouse gases was as follows:
- CO2: 76.6%
- N2O: 8.5%
- CH4: 13.0%
- F-gases: 1.9%
Evolution of emissions and demographic indicators over time EDGAR data also provide a long-term view of the development of emissions and related demographic and economic indicators for Slovakia. Compared to previous reference years, such as 1990 (baseline year for national greenhouse gas inventories), 2005 (entry of the Kyoto Protocol) and 2015 (Paris Agreement), we can observe the following trends:
| Year | GHG emissions (Mt CO2eq/year) | GHG emissions per capita (t CO2eq/capita/year) | GHG emissions per unit of GDP PPP (t CO2eq/thousand USD/year) | Population (million) |
|---|---|---|---|---|
| 2024 | 39,001 | 7,164 | 0,178 | 5,444 |
| 2015 | 43,930 | 8,076 | 0,242 | 5,439 |
| 2005 | 51,095 | 9,464 | 0,409 | 5,399 |
| 1990 | 73,845 | 13,963 | 0,795 | 5,288 |
Sectoral changes in emissions (2024 vs. reference years) An analysis of emissions changes by sector in 2024 compared to 1990, 2005 and 2023 shows diverse trends:
| Sector | 2024 vs 1990 | 2024 vs 2005 | 2024 vs 2023 |
|---|---|---|---|
| Energy industry | -71% | -64% | -8% |
| Industrial combustion and processes | -41% | -10% | -4% |
| Buildings | -75% | -31% | +2% |
| transportation | +80% | +13% | 0% |
| Fuel extraction | -34% | -38% | -9% |
| Agriculture | -62% | -8% | 0% |
| Waste | +30% | +16% | -1% |
| All sectors | -47% | -24% | -3% |
The data show that Slovakia (as part of the EU27) has recorded significant emission reductions in most sectors between 1990 and 2005. Particularly significant reductions occurred in the energy industry and the buildings sector. On the contrary, emissions from transport have increased by 80 % since 1990 and by 13 % since 2005.
EDGAR methodology and context The EDGAR database uses a bottom-up methodology for calculating emissions that is in line with IPCC (Intergovernmental Panel on Climate Change) guidelines and is applied globally, ensuring consistency and comparability of data across countries. However, it is important to note that EDGAR estimates may differ from official national inventories submitted under the United Nations Framework Convention on Climate Change (UNFCCC) due to different data sources, methodologies and approaches. Nevertheless, EDGAR represents a valuable independent source of information that complements national inventories and serves as a reference benchmark, especially where official data may not be sufficiently detailed or regular. EDGAR data is also used in IPCC assessment reports and UNEP Emission Gap Reports.
The data presented in this report are transparent and available for download and further analysis on the EDGAR website. Their interpretation should also take into account the uncertainties in the estimates, which range from approximately -9 % to +16 % for global greenhouse gas emissions and between -12.0 % and +22.0 % for country-level CO2 emissions.
