Bulgaria in context

0.08% vs 0.08%

Share of people vs share of CO₂

Bulgaria is home to 0.08% of the world’s population and produces 0.08% of its fossil CO₂, so its share of emissions is smaller than its share of people.

−59%

Change since 1990

Emissions in 2024 were 59% lower than in 1990, the baseline year of the Kyoto Protocol (76.6 Mt then). World emissions rose 70% over the same period.

35 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Bulgaria was responsible for 35.3 Mt in 2023, about the same as the 34.5 Mt produced within its borders.

165 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Bulgaria came with about 165 g of CO₂ in 2024 (world: 218 g), pointing to a cleaner energy mix than the world average.

0.34 kg

CO₂ per dollar of GDP

Its economy emitted 0.34 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 1.2× the world average of 0.29 kg.

What are Bulgaria’s CO₂ emissions per person?

Bulgaria emits 4.7 tonnes per person, close to the world average of 4.7 t. Per-person emissions divide the national total by population (6.8 million people in 2024).

Are Bulgaria’s CO₂ emissions rising or falling?

Emissions fell 8.4% in 2024 compared with 2023. Compared with 2005, emissions are down 38%. Emissions peaked in 1987 at 91.3 million tonnes and are now 65% lower.

What is the main source of CO₂ emissions in Bulgaria?

Oil is the largest source, at 43% of Bulgaria’s fossil and industry CO₂ in 2024 (13.6 million tonnes).

What are Bulgaria’s consumption-based CO₂ emissions?

About 35.3 million tonnes in 2023, roughly the same as its production-based emissions of 34.5 million tonnes. Consumption-based accounting adds the emissions embodied in imports and subtracts those in exports.

How much has Bulgaria contributed to historical CO₂ emissions?

Since 1750, Bulgaria has emitted about 4 billion tonnes of fossil CO₂, 0.2% of the world total, the 49th largest historical contribution.
