Lowest CO2 Emissions Per Capita Countries (2026)

What this list shows

This page ranks the bottom 25 countries by territorial CO₂ emissions per capita—tonnes of CO₂ equivalent emitted per person per year. Countries at the low end typically have lower energy consumption per person, fewer cars and flights, less industrialization, or a larger share of renewables or hydropower. Many are in Africa, South Asia, or Central America. Low per capita emissions do not automatically mean strong climate leadership—they often reflect development levels, access to energy, and economic structure. As economies grow, emissions may rise unless clean energy and efficiency keep pace.

This list complements the global pillar page, which offers the full ranking. Here we focus on the lowest emitters and what drives their figures.

Common patterns

Countries at the bottom of the global ranking tend to share traits: lower income per capita, less car ownership, limited air travel, smaller industrial base, and sometimes heavy reliance on biomass or hydropower. Some have large rural populations with minimal grid access. Others have focused on renewables or have energy-intensive industries that are modest in scale. It is important to note that low per capita emissions in developing countries often coexist with emissions embedded in exports—goods manufactured for wealthy consumers elsewhere. Consumption-based accounting assigns those emissions to the buyer country, which can shift the picture.

How to interpret extremes

Very low per capita emissions reflect real differences in lifestyle and economy, but they do not by themselves indicate climate progress. Many low-emitting countries aspire to develop—and that can mean rising emissions unless clean energy grows faster. Climate justice arguments often stress that historical responsibility lies with high emitters, while many low emitters need room to develop. Understanding both extremes—highest and lowest—helps frame the global challenge. Explore country profiles to see drivers, trends, and policy context.

Limits and data notes

Data years vary by country; we use the latest available. Territorial emissions count production within borders—consumption-based figures can differ. Some countries have patchy reporting; rankings can shift as new data is released. For full details on data sources and calculations, see our methodology.
