Slovenia's Sources of CO2 Emissions
Key Insights
2024 CO2 Emissions Profile
In 2024, Slovenia's emissions from these sources totalled around 15 megatonnes CO2e. Oil was largest at about 6.6 megatonnes CO2, or 43.8%, followed by coal at 3.8 megatonnes CO2 (25%), land-use at 2.3 megatonnes CO2 (15.1%), gas at 1.8 megatonnes CO2 (11.7%), and other fossil sources at 0.7 megatonnes CO2 (4.5%). The profile was dominated by oil and coal. Over the ten years to 2024, coal and land-use emissions fell by around 0.19 and 0.31 megatonnes CO2 per year, while oil declined slightly; gas and other fossil emissions edged up.
Historic Coal Emissions
Coal emissions were minimal in the late nineteenth century, rising to roughly 1.3 megatonnes CO2 by 1940 before falling to zero in 1944. They then climbed sharply, reaching nearly 7 megatonnes CO2 by 1989 and peaking at about 7.1 in 1990. After fluctuating at high levels, they declined from the late 2000s to around 3.8 megatonnes CO2 in 2024.
Historic Oil Emissions
Oil emissions were negligible for much of the early record, though they briefly reached about 0.15 megatonnes CO2 in 1930. They rose rapidly after the late 1940s, from around 0.03 to 7.7 megatonnes CO2 by 1978. Emissions then varied at high levels, peaking at roughly 8.8 in 2008, before ending at around 6.6 megatonnes CO2 in 2024.
Historic Gas Emissions
Gas emissions were near zero until the early 1960s, then grew from around 0.05 megatonnes CO2 to roughly 1.8 by 1991. They subsequently remained broadly stable, fluctuating between about 1.5 and 1.9 megatonnes CO2 and peaking at roughly 1.9 in 2005. Gas emissions ended at around 1.8 megatonnes CO2 in 2024.
Historic Land-use Emissions
Land-use emissions began at around 0.7 megatonnes CO2 in the early 1850s and rose to nearly 2.8 by 1931. They then declined for several decades, becoming a net removal of about 1.5 megatonnes CO2 in 1995 and reaching a low near 1.7 in 1996. Emissions later rose sharply, peaking at roughly 6.7 in 2007, before falling to around 2.3 megatonnes CO2 in 2024.
Historic Other Fossil Emissions
Other fossil emissions were close to zero until the mid-twentieth century, then rose gradually to around 0.7 megatonnes CO2 by 2002, despite fluctuations and a high near 0.8 in 1990. They rose again to a peak of roughly 0.9 megatonnes CO2 in 2008, then declined overall to around 0.7 megatonnes CO2 in 2024.
Background
The chart shows a national breakdown by source of the yearly CO2 emissions from human activities and processes expressed in megatonnes. It is critical to know and track the sources of national CO2 emissions in order to understand their individual impacts on climate change.
The sources of human CO2 emissions are
- CO2 From Fossil Fuels and Industry: coal, oil, gas combustion, other fossil processes
- CO2 From Land-Use, Land-Use Change, and Forestry
Coal, oil and gas combustion
Fossil fuel CO2 emissions from the combustion of coal, oil and gas are emitted by processes in electricity generation, transport, industry, and the building sector. All processes can be linked to human activities. Examples include driving cars with combustion engines burning diesel or gas, or electric cars charged by electricity from a power plant that burns coal.
Other fossil processes
Fossil CO2 emissions from other processes include sources like cement manufacturing and production of chemicals and fertilizers. Cement also has an absorption factor highlighted in the absorption breakdown chart.
Land-use change
Human civilization emits CO2 by changing and managing its land. Those emissions come, for example, from deforestation, logging, forest degradation, harvest activities and shifting agriculture cultivation. Land-use change also absorbs considerable amounts of CO2, which is shown in the absorption breakdown chart. Land-use change emits more than it absorbs, so the net effect is still emissions, but less than for coal, oil and gas.

Units and Measures
CO2 emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

National CO2 emissions data through 2024 is from the Global Carbon Project and covers fossil sources and land-use change.
The Key Insights paragraph was created using a large language model (LLM) in combination with our data, historic events, and a structured approach for best accuracy by separating the context generation from the interpretation and narrative.
