In the last recorded year (2019), Samoa was the world’s 172nd largest producer of yearly carbon dioxide emissions and contributed 0.01% of all global emissions. The top three emitters in the same period were China, the United States, and India. These three nations produced 25.2%, 12%, and 7% of global emissions respectively.

In 2019, Samoa emitted 791k metric tonnes of carbon dioxide equivalent, or MtCO₂e. This represented an increase in emissions from 2018 by 1.1%.

Emissions per capita in Samoa – average household carbon footprint

The population of Samoa is 200k. On a per capita basis, they produce 4.0 tonnes of carbon dioxide equivalent (tCO2e) per person. This places them 118th out of 191 on emissions produced per capita. The top three emitters per capita are Solomon Islands, Qatar, and Kuwait.

What is the largest source of greenhouse gas emissions in Samoa?

In 2019, Samoa produced 684k metric tonnes of greenhouse gas emissions. This was an increase of 1.2% from 2018. 43.2% of these emissions came from CO2, 45.5% came from CH4, and 9.5% came from N2O.

The sector that produced the most emissions in 2019 was the energy industry. Energy produced 295k of greenhouse gas (GHG) emissions. This amounted to 43.2% of total GHG in Samoa. The second and third largest emitting sectors were agriculture and waste– producing 32.7% and 22.2% of total GHG respectively.


The industry that produced the most energy related emissions was the transportation sector, emitting 173k tonnes of greenhouse gas. The second and third largest emitting sectors were electricity/heat and building – producing 72.6k and 27.8k tonnes of GHG each.

Land Use Change and Forestry

Land use change and forestry (LUCF), such as deforestation and conversion of natural ecosystems to agricultural or urban areas, can have a significant impact on carbon emissions.

  • Trees and other vegetation absorb and store carbon through the process of photosynthesis, and when they are cut down or burned, that stored carbon is released into the atmosphere.
  • Deforestation and other forms of land use change can also reduce the ability of ecosystems to absorb and store carbon in the future. Additionally, the conversion of land for agriculture or urban development can lead to the release of carbon stored in the soil.
  • On the other hand, sustainable forestry practices, such as reforestation and afforestation, can help to remove carbon from the atmosphere and store it in trees and other vegetation.

In the case of Samoa, their LUCF had a negative impact on their emissions, increasing their footprint by 107k tonnes.

After accounting for land use change and forestry, the total amount of greenhouse emissions in Samoa in 2019 was 791k metric tonnes.

Is there a correlation between greenhouse gas emissions and economic growth?

In 2019, gross domestic product (GDP) in Samoa grew by 3.7% from the previous year. Measured in US dollars, the economy went from $821m to $852m. In the same period carbon emissions increased by 1.1%. Over a ten year period from 2009 to 2019, GDP grew by 35.7%, while emissions have increased by 33.4%.

To put this into context, the compound annual growth rate of GDP in Samoa over the previous ten years was 3.1% and the CAGR for greenhouse gas emissions was 2.9%.
