Slovenia in context

0.03% vs 0.03%

Share of people vs share of CO₂

Slovenia is home to 0.03% of the world’s population and produces 0.03% of its fossil CO₂, so its share of emissions is larger than its share of people.

−15%

Change since 1990

Emissions in 2024 were 15% lower than in 1990, the baseline year of the Kyoto Protocol (15.1 Mt then). World emissions rose 70% over the same period.

20 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Slovenia was responsible for 19.7 Mt in 2023, 64% more than the 12.0 Mt produced at home: it is a net importer of emissions.

161 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Slovenia came with about 161 g of CO₂ in 2024 (world: 218 g), pointing to a cleaner energy mix than the world average.

0.18 kg

CO₂ per dollar of GDP

Its economy emitted 0.18 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 36% below the world average of 0.29 kg.

Questions and answers

How much CO₂ does Slovenia emit?

Slovenia emitted 12.8 million tonnes of CO₂ from fossil fuels and industry in 2024, 0.0% of global emissions. That is about 0 tonnes every second.

What are Slovenia’s CO₂ emissions per person?

Slovenia emits 6.0 tonnes per person, 1.3× the world average of 4.7 t. Per-person emissions divide the national total by population (2.1 million people in 2024).

Are Slovenia’s CO₂ emissions rising or falling?

Emissions rose 6.7% in 2024 compared with 2023. Compared with 2005, emissions are down 24%. Emissions peaked in 2008 at 18.3 million tonnes and are now 30% lower.

What is the main source of CO₂ emissions in Slovenia?

Oil is the largest source, at 51% of Slovenia’s fossil and industry CO₂ in 2024 (6.6 million tonnes).

What are Slovenia’s consumption-based CO₂ emissions?

About 19.7 million tonnes in 2023, 64% more than the 12.0 million tonnes emitted within its borders, because it imports more carbon-intensive goods than it exports. Consumption-based accounting adds the emissions embodied in imports and subtracts those in exports.

How much has Slovenia contributed to historical CO₂ emissions?

Since 1750, Slovenia has emitted about 1 billion tonnes of fossil CO₂, 0.1% of the world total, the 84th largest historical contribution.
