CO₂ Emissions from Electricity by Country (g CO₂/kWh) 2026

Which countries have the cleanest electricity? Norway generates power with just 29 grams of CO₂ per kilowatt-hour. Meanwhile, countries like China and India emit over 600 grams. This massive gap reveals which nations lead in clean energy and which remain trapped in fossil fuels. Our analysis ranks 100 countries by their electricity emissions, showing the stark reality of global power generation and carbon intensity.

What Is CO₂ per kWh?

CO₂ per kilowatt-hour measures the carbon emissions from electricity generation. It's the amount of carbon dioxide released when producing one unit of electricity. Lower numbers mean cleaner power. Higher numbers mean dirtier power.

For context:

• Norway: 29 g CO₂/kWh - Nearly all hydroelectric power. Virtually zero carbon emissions
• France: 56 g CO₂/kWh - Nuclear and hydroelectric dominate. Very clean electricity
• Germany: 380 g CO₂/kWh - Mix of coal, gas, and renewables. Moderate emissions
• China: 620 g CO₂/kWh - Coal-heavy. Extremely high carbon intensity
• India: 650 g CO₂/kWh - Coal-dependent. Very high electricity emissions

Why Electricity Emissions Matter

Climate Change: Electricity generation accounts for 25% of global carbon emissions. Switching to clean power is essential for fighting climate change.

Air Pollution: Coal plants emit not just CO₂ but also sulfur dioxide, nitrogen oxides, and particulates. These cause respiratory disease and premature death.

Economic Competitiveness: Countries with low electricity emissions attract clean-tech companies. Norway and Switzerland lead in renewable energy investment.

Energy Independence: Countries relying on coal imports face price volatility. Renewable energy is domestic and stable.

Regional Patterns

Europe - Leading in Clean Energy

Nordic countries (Norway, Sweden, Finland) have the lowest carbon intensity due to hydroelectric and nuclear power. France also ranks high thanks to nuclear energy. Even Germany, despite coal use, is transitioning to renewables.

Americas - Mixed Results

Costa Rica and Brazil have clean electricity from hydroelectric power. The United States and Mexico rely heavily on fossil fuels, resulting in higher CO₂ emissions.

Asia - Coal Dominance

China and India, the world's largest economies, have extremely high electricity emissions due to coal dependence. However, both are rapidly expanding renewable capacity.

Africa - Emerging Potential

Kenya leads with geothermal energy. Most African nations have low electricity emissions but lack generation capacity, limiting economic growth.

Why Emissions Vary So Much

Energy Mix: Countries using hydroelectric, nuclear, or wind power have low carbon intensity. Countries relying on coal have high emissions.

Geography: Norway has mountains for hydroelectric dams. Costa Rica has geothermal activity. Geography determines available energy sources.

Investment: Rich countries invest in renewable infrastructure. Poor countries can't afford it, so they use cheap coal.

Policy: Countries with carbon taxes and renewable mandates transition faster. Countries without climate policy stay coal-dependent.

Natural Resources: Coal-rich countries like Poland and Czech Republic use domestic coal. Oil-rich countries use gas. This shapes their electricity emissions.

Data Methodology

What We Measured: We analyzed CO₂ emissions from electricity generation across 205 countries. The metric is grams of CO₂ per kilowatt-hour of electricity produced.

Data Source: Our World in Data (OWID) - Energy dataset. This includes direct emissions from power plants only (not lifecycle emissions).

Why This Matters: A country with 30 g CO₂/kWh (Norway) produces electricity with minimal climate impact. A country with 700 g CO₂/kWh (Poland) produces electricity that's 23 times dirtier.

2024 Data: Latest available year from OWID dataset

2026 Projections: Based on historical trends from 2015-2024. Countries improving renewable capacity show declining emissions. Countries expanding coal show increasing emissions. Projections calculated using linear trend analysis.

Important Note: This measures direct emissions only. Lifecycle emissions (including manufacturing, transportation, decommissioning) are higher for all sources but follow similar patterns.
