Emissions per capita in Antigua And Barbuda – average household carbon footprint

The population of Antigua and Barbuda is 98.7k. On a per capita basis, they produce 12.3 tonnes of carbon dioxide equivalent (tCO2e) per person. This places them 30th 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 Antigua and Barbuda?

In 2019, Antigua and Barbuda produced 1.22m metric tonnes of greenhouse gas emissions. This was an increase of 2.6% from 2018. 42.4% of these emissions came from CO2, 16.6% came from CH4, and 0.95% came from N2O.

The sector that produced the most emissions in 2019 was the energy industry. Energy produced 516k of greenhouse gas (GHG) emissions. This amounted to 42.4% of total GHG in Antigua and Barbuda. The second and third largest emitting sectors were industrial processes and bunker fuels- producing 4% and 18.5% of total GHG respectively.


The industry that produced the most energy related emissions was the electricity/heat sector, emitting 288k tonnes of greenhouse gas. The second and third largest emitting sectors were transportation and building – producing 215k and 12.8k 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 Antigua and Barbuda, their LUCF had no impact on their emissions.

After accounting for land use change and forestry, the total amount of greenhouse emissions in Antigua and Barbuda in 2019 was 1.22m metric tonnes.

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

In 2019, gross domestic product (GDP) in Antigua and Barbuda grew by 5.1% from the previous year. Measured in US dollars, the economy went from $1.61bn to $1.69bn. In the same period carbon emissions increased by 2.6%. Over a ten year period from 2009 to 2019, GDP grew by 37.4%, while emissions have decreased by -36.5%.

To put this into context, the compound annual growth rate of GDP in Antigua and Barbuda over the previous ten years was 3.2% and the CAGR for greenhouse gas emissions was -4.4%.
