Carbon Footprint by Country
Per Capita Carbon Emissions by Country
When comparing carbon footprints between countries, per capita emissions (CO2 per person) is the most meaningful metric. It accounts for population differences and shows the true average impact of each citizen.
| Country | Per Capita (tCO2) | Total (Gt CO2) | Population (M) | Primary Sources |
|---|---|---|---|---|
| United States | 14.9 | 5.0 | 335 | Transport, energy, industry |
| Australia | 15.3 | 0.4 | 26 | Coal power, mining |
| Canada | 15.5 | 0.6 | 39 | Oil sands, heating, transport |
| Saudi Arabia | 16.2 | 0.6 | 37 | Oil production, cooling |
| South Korea | 12.4 | 0.6 | 52 | Industry, coal power |
| Russia | 11.4 | 1.7 | 144 | Gas, oil, industry |
| Japan | 8.5 | 1.1 | 125 | Industry, coal imports |
| Germany | 8.1 | 0.7 | 84 | Coal, industry, transport |
| China | 8.0 | 11.4 | 1,425 | Coal power, industry |
| UK | 5.2 | 0.3 | 68 | Gas, transport, heating |
| France | 4.7 | 0.3 | 68 | Nuclear (low-carbon grid) |
| Global Average | 4.7 | 37.4 | 8,045 | Mixed |
| Brazil | 2.3 | 0.5 | 216 | Deforestation, transport |
| India | 1.9 | 2.7 | 1,428 | Coal power, industry |
| Nigeria | 0.6 | 0.1 | 223 | Gas flaring, generators |

Top 10 Total Emitting Countries
Total emissions matter for global climate impact, but they often obscure individual responsibility. China's total is high because of its 1.4 billion population, not because each Chinese citizen pollutes more than an American.
| Rank | Country | Total (Gt CO2) | % of Global | Per Capita (tCO2) |
|---|---|---|---|---|
| 1 | China | 11.4 | 30.5% | 8.0 |
| 2 | United States | 5.0 | 13.4% | 14.9 |
| 3 | India | 2.7 | 7.2% | 1.9 |
| 4 | Russia | 1.7 | 4.5% | 11.4 |
| 5 | Japan | 1.1 | 2.9% | 8.5 |
| 6 | Iran | 0.7 | 1.9% | 8.3 |
| 7 | Germany | 0.7 | 1.9% | 8.1 |
| 8 | South Korea | 0.6 | 1.6% | 12.4 |
| 9 | Saudi Arabia | 0.6 | 1.6% | 16.2 |
| 10 | Indonesia | 0.6 | 1.6% | 2.3 |
Why Per Capita Emissions Matter More
Total national emissions are often used in political debates, but they can be misleading. Consider:
- China emits 11.4 Gt — but has 1.4 billion people. Each person emits ~8.0 tonnes.
- The US emits 5.0 Gt — but has 335 million people. Each person emits ~14.9 tonnes.
- If every person on Earth emitted at the US rate, global emissions would be ~120 Gt/year — over 3x today's total.
- If everyone emitted at India's rate, global emissions would be ~15 Gt/year — well within climate targets.
Per capita emissions reflect individual consumption choices, lifestyle, and the carbon intensity of national infrastructure. This is why international climate agreements focus on per capita targets alongside total reduction goals.
Production vs Consumption-Based Emissions
There are two ways to measure a country's carbon footprint:
- Production-based: CO2 emitted within the country's borders (standard reporting).
- Consumption-based: CO2 emitted to produce the goods and services a country consumes — including imports.
| Country | Production (tCO2/cap) | Consumption (tCO2/cap) | Difference |
|---|---|---|---|
| US | 14.9 | 16.1 | +8% |
| UK | 5.2 | 7.4 | +42% |
| Germany | 8.1 | 10.1 | +25% |
| Japan | 8.5 | 9.7 | +14% |
| China | 8.0 | 6.7 | -16% |
| India | 1.9 | 1.7 | -11% |
Consumption-based accounting reveals that developed nations "offshore" significant emissions to manufacturing countries like China and India. The UK's consumption footprint is 42% higher than its production figure.
Historical Trends
Carbon emissions are changing at different rates around the world:
- US: Peaked at ~22 tCO2/capita in the 1970s. Declining due to coal-to-gas switching, renewable growth, and efficiency gains.
- UK: Declined ~50% since 1990. Strong renewable energy buildout and coal phase-out.
- China: Rose rapidly from ~3 tCO2 in 2000 to ~8 in 2024. Now showing signs of plateauing as renewables expand.
- India: Rising from ~1.0 in 2000 to ~1.9 in 2024. Still far below the global average with continued growth expected.
- EU average: Declined from ~9 in 1990 to ~5.8 in 2024.

Frequently Asked Questions
Why are US emissions so high compared to Europe?
Several factors: larger homes requiring more heating/cooling, higher car dependency (fewer public transit options), more energy-intensive industry, and historically cheaper fossil fuels. The US also has lower gas taxes, which reduce the incentive to drive less or buy efficient vehicles.
Is China's per capita emissions higher than the EU's?
Yes. China's per capita emissions (~8.0 tCO2) surpassed the EU average (~5.8) around 2019. However, on a consumption basis, the EU still consumes more CO2 per person (~7.2 tCO2) than China (~6.7 tCO2) because of imports.
What country has the lowest carbon footprint per person?
Many low-income nations have per capita emissions below 0.5 tCO2, including much of sub-Saharan Africa. Among larger economies, the lowest is India at ~1.9 tCO2 per person — about one-eighth of the US rate.
