Top 10 countries with the lowest carbon footprint in 2023

Carbon footprint is a measure of the total amount of greenhouse gas emissions that are caused by an individual, organization, product, or country. It is usually expressed in tons of carbon dioxide equivalent (CO2e) per year. Carbon footprint is an important indicator of the environmental impact of human activities, as greenhouse gases contribute to global warming and climate change.

There are different methods to calculate the carbon footprint of a country, depending on whether the focus is on the emissions from production or consumption. Production-based accounting measures the emissions that occur within a country’s territory, regardless of where the goods and services are consumed. Consumption-based accounting measures the emissions that are associated with the goods and services consumed by a country’s residents, regardless of where they are produced.

In this article, we will use the consumption-based accounting method, as it reflects the demand-side drivers of emissions and the responsibility of consumers for their choices. We will use the data from the Emissions Database for Global Atmospheric Research (EDGAR), which provides consistent and comparable estimates of greenhouse gas emissions for all countries in the world from 1970 to 2020. We will also use the population data from the World Bank to calculate the per capita carbon footprint of each country.

Based on these data sources, here are the top 10 countries with the lowest carbon footprint in 2020, the latest year for which data is available:

5Central African Republic1.30.27

As we can see from the table, most of the countries with the lowest carbon footprint are located in Africa, and have low levels of income, industrialization, and urbanization. They also have low levels of energy consumption and rely mostly on renewable sources such as biomass, hydro, and solar power. However, these countries also face many challenges such as poverty, malnutrition, disease, conflict, and environmental degradation.


Reducing the carbon footprint is essential for mitigating climate change and achieving sustainable development. However, there is no one-size-fits-all solution for every country, as each country has different circumstances and needs. Therefore, it is important to adopt a balanced and equitable approach that considers both the historical responsibility and the current capacity of each country to reduce its emissions.

Some of the strategies that can help reduce the carbon footprint include:

  • Switching to renewable energy sources such as wind, solar, hydro, and geothermal power.
  • Improving energy efficiency and conservation in buildings, transportation, industry, and agriculture.
  • Promoting low-carbon lifestyles and consumption patterns such as eating less meat and dairy, buying local and organic products, recycling and reusing materials, and avoiding unnecessary travel.
  • Enhancing carbon sinks such as forests, wetlands, and soils that can absorb and store carbon dioxide from the atmosphere.
  • Supporting international cooperation and action on climate change through agreements, policies, finance, technology transfer, and capacity building.

By taking these steps, we can not only reduce our carbon footprint but also improve our quality of life and well-being.


Here are some of the most frequently asked questions about carbon footprint:

Q: What is the global average carbon footprint per capita?

A: According to EDGAR data, the global average carbon footprint per capita was about 4.7 t CO2e in 2020.

Q: Which country has the highest carbon footprint per capita?

A: According to EDGAR data, Qatar had the highest carbon footprint per capita in 2020 with 37 t CO2e, followed by Trinidad and Tobago with 30 t CO2e, and Kuwait with 25 t CO2e.

Q: How can I calculate my personal carbon footprint?

A: There are many online tools and calculators that can help you estimate your personal carbon footprint based on your lifestyle choices such as energy use, transportation, food, waste, etc. For example, you can use this calculator from Carbon Footprint Ltd.

Q: How can I offset my carbon footprint?

A: Offsetting your carbon footprint means compensating for your emissions by supporting projects that reduce or remove greenhouse gases from the atmosphere. For example, you can invest in renewable energy, energy efficiency, forest conservation, or carbon capture and storage projects. However, offsetting should not be seen as a substitute for reducing your emissions, but rather as a complementary measure.

Q: What is the carbon footprint of a product?

A: The carbon footprint of a product is the total amount of greenhouse gas emissions that are generated throughout its life cycle, from raw material extraction, processing, manufacturing, transportation, use, to disposal or recycling. It is also known as the cradle-to-grave or life cycle assessment (LCA) approach. Some products may have labels or certifications that indicate their carbon footprint or environmental impact. For example, you can check this website from the Carbon Trust for more information.
