Mauritius in context

0.02% vs 0.01%

Share of people vs share of CO₂

Mauritius is home to 0.02% of the world’s population and produces 0.01% of its fossil CO₂, so its share of emissions is smaller than its share of people.

+213%

Change since 1990

Emissions in 2024 were 213% higher than in 1990, the baseline year of the Kyoto Protocol (1.5 Mt then). World emissions rose 70% over the same period.

8 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Mauritius was responsible for 7.9 Mt in 2023, 72% more than the 4.6 Mt produced at home: it is a net importer of emissions.

195 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Mauritius came with about 195 g of CO₂ in 2024 (world: 218 g), pointing to a cleaner energy mix than the world average.

0.16 kg

CO₂ per dollar of GDP

Its economy emitted 0.16 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 44% below the world average of 0.29 kg.

Questions and answers

How much CO₂ does Mauritius emit?

Mauritius emitted 4.7 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 Mauritius’ CO₂ emissions per person?

Mauritius emits 3.7 tonnes per person, 22% below the world average of 4.7 t. Per-person emissions divide the national total by population (1.3 million people in 2024).

Are Mauritius’ CO₂ emissions rising or falling?

Emissions rose 2.2% in 2024 compared with 2023. Compared with 2005, emissions are up 42%. 2024 was the highest year on record.

What is the main source of CO₂ emissions in Mauritius?

Oil is the largest source, at 66% of Mauritius’ fossil and industry CO₂ in 2024 (3.1 million tonnes).

What are Mauritius’ consumption-based CO₂ emissions?

About 7.9 million tonnes in 2023, 72% more than the 4.6 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 Mauritius contributed to historical CO₂ emissions?

Since 1750, Mauritius has emitted about 0 billion tonnes of fossil CO₂, 0.0% of the world total, the 137th largest historical contribution.
