Average carbon footprint in United States

United States emits about 14.2 tCO2e per person per year (territorial emissions). That places it around #4 globally, which is considered very high on a per-person basis.

This is ~3× the global median (~4.7 tCO2e per person). Within North America, United States ranks around #1 and sits about 6% above the regional median of ~13.4.

Population is roughly 340.1 million (2024).

GDP per capita is approximately $84,534 (2024).

Urban population is around 80% (2024).

Electricity renewables share is roughly ~24% of electricity.

Grid carbon intensity is roughly ~384 gCO2/kWh.

Per-capita emissions divide a country's total CO₂ output by its population. That lets us compare nations fairly regardless of size. A large country with high total emissions can still have low per-person emissions if its population is very large.

Globally, the main sectors driving emissions are electricity and heat, transport, industry, buildings, and food. The mix varies by country: colder climates often use more heating; car-dependent societies have higher transport emissions; industrial economies tend to show more industry-related CO₂.

For United States, with very high per-capita emissions, the gap to global and climate targets is substantial. Decoupling economic activity from emissions—through clean energy, efficiency, and behavior change—is the main pathway to reduction.

With GDP per capita around $84,534 (2024), United States is a high-income economy. Higher incomes often correlate with greater energy use, car ownership, and consumption-based emissions. Policy, energy mix, and urban planning can significantly change that relationship.

Around 80% of the population lives in urban areas (2024). Urbanization can affect transport patterns, building density, and heating and cooling demand. Denser cities often support public transit and district heating; sprawl tends to increase car dependency and per-capita emissions.

Electricity mix and carbon intensity affect how much emissions drop when transport and heating electrify. Improving the grid is often a prerequisite for deep decarbonization of other sectors.

Territorial emissions count CO₂ produced within national borders. Consumption-based emissions attribute CO₂ to where goods are consumed. Both perspectives matter for understanding the full carbon footprint.

Territorial emissions count CO₂ produced within a country's borders. Consumption-based emissions attribute CO₂ to the country where goods and services are consumed, including imports. United States's per-capita figure above is territorial (~14.2 tCO2e/person/year). Consumption-based data for United States is around ~15.8 tCO2e/person/year, indicating imported carbon footprint. Both perspectives matter for understanding the full impact.

Targeted actions depend on the country's starting point. For United States, with very high per-capita emissions, potential levers include:

• Improving building insulation and energy efficiency
• Expanding public transit and active mobility
• Improving industrial process efficiency
• Retrofitting older buildings with heat pumps
• Electrifying industrial heating and process heat
• Cutting down on air travel and long-haul freight
• Reducing car use and choosing electric vehicles
• Phasing out coal and fossil gas in power generation
• Increasing renewable share in electricity generation
• Switching to renewable electricity and heat pumps for heating
• Reducing food waste along the supply chain
• Shifting diets toward less carbon-intensive foods
