In 2019, St. Lucia emitted 735k metric tonnes of carbon dioxide equivalent, or MtCO₂e. This represented an increase in emissions from 2018 by 1.7%.

Emissions per capita in St. Lucia – average household carbon footprint

The population of St. Lucia is 184k. 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 St. Lucia?

In 2019, St. Lucia produced 882k metric tonnes of greenhouse gas emissions. This was an increase of 1.4% from 2018. 60.8% of these emissions came from CO2, 30.7% came from CH4, and 3.1% came from N2O.

The sector that produced the most emissions in 2019 was the energy industry. Energy produced 536k of greenhouse gas (GHG) emissions. This amounted to 60.8% of total GHG in St. Lucia. The second and third largest emitting sectors were waste and bunker fuels- producing 29.9% and 13.8% of total GHG respectively.


The industry that produced the most energy related emissions was the electricity/heat sector, emitting 266k tonnes of greenhouse gas. The second and third largest emitting sectors were transportation and building – producing 221k and 31.6k 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 St. Lucia, their LUCF had a positive impact on their emissions, reducing their footprint by 146k tonnes.

After accounting for land use change and forestry, the total amount of greenhouse emissions in St. Lucia in 2019 was 735k metric tonnes.

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

In 2019, gross domestic product (GDP) in St. Lucia grew by 2.6% from the previous year. Measured in US dollars, the economy went from $2.07bn to $2.12bn. In the same period carbon emissions increased by 1.7%. Over a ten year period from 2009 to 2019, GDP grew by 51.2%, while emissions have decreased by -52%.

To put this into context, the compound annual growth rate of GDP in St. Lucia over the previous ten years was 4.2% and the CAGR for greenhouse gas emissions was -7.1%.
