Ireland in context

0.06% vs 0.09%

Share of people vs share of CO₂

Ireland is home to 0.06% of the world’s population and produces 0.09% of its fossil CO₂, so its share of emissions is larger than its share of people.

+1%

Change since 1990

Emissions in 2024 were 1% higher than in 1990, the baseline year of the Kyoto Protocol (32.9 Mt then). World emissions rose 70% over the same period.

41 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Ireland was responsible for 40.8 Mt in 2023, 21% more than the 33.6 Mt produced at home: it is a net importer of emissions.

183 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Ireland came with about 183 g of CO₂ in 2024 (world: 218 g), pointing to a cleaner energy mix than the world average.

0.12 kg

CO₂ per dollar of GDP

Its economy emitted 0.12 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 59% below the world average of 0.29 kg.

Questions and answers

How much CO₂ does Ireland emit?

Ireland emitted 33.3 million tonnes of CO₂ from fossil fuels and industry in 2024, 0.1% of global emissions. That is about 1 tonnes every second.

What are Ireland’s CO₂ emissions per person?

Ireland emits 6.3 tonnes per person, 1.3× the world average of 4.7 t. Per-person emissions divide the national total by population (5.3 million people in 2024).

Are Ireland’s CO₂ emissions rising or falling?

Emissions fell 0.9% in 2024 compared with 2023. Emissions peaked in 2005 at 48.2 million tonnes and are now 31% lower.

What is the main source of CO₂ emissions in Ireland?

Oil is the largest source, at 56% of Ireland’s fossil and industry CO₂ in 2024 (18.7 million tonnes).

What are Ireland’s consumption-based CO₂ emissions?

About 40.8 million tonnes in 2023, 21% more than the 33.6 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 Ireland contributed to historical CO₂ emissions?

Since 1750, Ireland has emitted about 2 billion tonnes of fossil CO₂, 0.1% of the world total, the 64th largest historical contribution.
