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

The population of St. Lucia is 184k. On a per capita basis, they produce 4.6 tonnes of CO2e per person, placing them 94th out of 191 on emissions produced per capita. The biggest per capita emitters are Qatar, Turkmenistan, Kuwait and Bahrain.

What is the largest source of greenhouse gas emissions in St. Lucia?


58.7% of emissions in St. Lucia came from Carbon Dioxide (CO2), 32.1% came from Methane (CH4), and 3.2% came from Nitrous Oxide (N2O).


The sector that produced the most emissions in 2020 was the energy industry, producing 499k of GHG emissions, constituting 58.7% of total.

The second and third largest emitting sectors were waste and bunker fuels, producing 31.3% and 7.3% of total GHG in St. Lucia.


The industry that produced the most energy related emissions was the electricity/heat industry, producing 249k of GHG emissions, constituting 29.3% of total emissions.

The second and third largest emitting sectors were transportation and building, emitting 208k and 26.7k 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, LUCF had a positive impact on St. Lucia’s emissions, decreasing their carbon footprint by 146k tonnes.

After accounting for land use change and forestry, the total amount of greenhouse gas emissions in St. Lucia in 2020 was 704k metric tonnes.

How vulnerable is St. Lucia to the impact of climate change?

The Notre Dame Global Adaptation Initiative (ND-GAIN) Index

The ND-GAIN Index measures countries’ vulnerability to global challenges, including climate change, and their readiness to improve resilience.

St. Lucia scores 52.9 on the ND-Gain Index and is classified in the ‘low vulnerability and high readiness’ category of climate change preparedness.

The index aims to assist businesses, governments, and communities in prioritising investments for a more efficient response to global shifts.

It is measured by combining two main components:

  1. Vulnerability: This evaluates a country’s vulnerability to environmental risks and its ability to adapt. It considers health, food and water availability, infrastructure, and ecosystem services. A higher score indicates greater vulnerability to environmental challenges.
  2. Readiness: This measures how well a country can leverage investments to mitigate climate change. It considers economic stability, governance, technology, and infrastructure. A higher score means a country is better prepared to implement resilience strategies.

This ranking helps identify areas where resources and adaptation strategies can be most effectively directed to mitigate risks and enhance resilience.

By combining these dimensions, the index provides a comprehensive approach to measuring countries’ ability to cope with the impacts of climate change.

Low vulnerability and high readiness in St. Lucia

In terms of readiness to adapt to climate change, St. Lucia ranks in the below average group. Globally, the average readiness score is 0.424, with St. Lucia posting a score of 0.454.

They show the greatest strength in governance aspects, while their performance in social aspects requires improvement.

  • Governance readiness refers to the political, legal, and regulatory aspects influencing a country’s adaptation to climate change, including stability, corruption control, and law enforcement.
  • Social readiness refers to the societal factors like inequality, education, and technology infrastructure that affect a country’s ability to adapt to and mitigate the impacts of climate change.

Regarding vulnerability to climate change, St. Lucia falls into the below average category. Compared to the global average vulnerability score of 0.431, St. Lucia has a score of 0.397.

Their resilience is most notable in habitat areas, yet they face significant challenges in health.

  • Human habitat refers to the growth of cities and their capacity to withstand climate change impacts like floods and heatwaves. Improved infrastructure enhances urban resilience to extreme weather events.
  • Health vulnerability refers to the impact of climate change on diseases and medical resources. Innovations can enhance resilience to vulnerabilities affecting human health through food, water insecurity, and extreme weather events.

The formula to calculate the ND-GAIN Index is

GAIN Index=(Readiness Indicators−Vulnerability Indicators+1)×50GAIN Index=(Readiness Indicators−Vulnerability Indicators+1)×50

In this formula:

  • The Readiness Indicators are measured on a scale of 0 to 1, where a higher score means that the readiness is better.
  • The Vulnerability Indicators are also measured on a scale of 0 to 1, but a lower score indicates better vulnerability in this case. 
  • The difference between the Readiness and Vulnerability scores is calculated and then incremented by 1. 
  • Finally, the result is multiplied by 50 to convert the GAIN Index score to a range of 0-100, where a higher score means the situation is better.

Is there a correlation between greenhouse gas emissions and economic growth in St. Lucia?

In 2020, the gross domestic product (GDP) in St. Lucia declined by -23.7% from the previous year, with the economy moving from $2.12bn to $1.62bn. During the same period, carbon emissions decreased by -3.4%. Over the ten-year period from 2010 to 2020, GDP grew 8.7%, while emissions increased by 6.3%.

To put this into context, the compound annual growth rate (CAGR) of GDP in St. Lucia over the past ten years was 0.84%, and the CAGR for greenhouse gas emissions was 0.62%.
