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 12.2 tonnes of CO2e per person, placing them 21st 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 Antigua and Barbuda?

Gases

39.4% of emissions in Antigua and Barbuda came from Carbon Dioxide (CO2), 17% came from Methane (CH4), and 0.98% came from Nitrous Oxide (N2O).

Sectors

The sector that produced the most emissions in 2020 was the industrial processes industry, producing 512k of GHG emissions, constituting 42.6% of total.

The second and third largest emitting sectors were energy and waste, producing 39.4% and 16.3% of total GHG in Antigua and Barbuda.

Energy

The industry that produced the most energy related emissions was the electricity/heat industry, producing 266k of GHG emissions, constituting 22.1% of total emissions.

The second and third largest emitting sectors were transportation and building, emitting 196k 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, LUCF had no impact on Antigua and Barbuda’s emissions, decreasing their carbon footprint by 0 tonnes.

After accounting for land use change and forestry, the total amount of greenhouse gas emissions in Antigua and Barbuda in 2020 was 1.2m metric tonnes.

How vulnerable is Antigua and Barbuda 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.

Antigua And Barbuda scores 49.1 on the ND-Gain Index and is classified in the ‘high 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.

High vulnerability and high readiness in Antigua and Barbuda

In terms of readiness to adapt to climate change, Antigua And Barbuda ranks in the below average group. Globally, the average readiness score is 0.424, with Antigua and Barbuda posting a score of 0.449.

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, Antigua And Barbuda falls into the above average category. Compared to the global average vulnerability score of 0.431, Antigua and Barbuda has a score of 0.467.

Their resilience is most notable in water areas, yet they face significant challenges in food.

  • Water vulnerability refers to the availability and reliability of water resources, critical for economies and livelihoods. Efficient water use and resilient systems are essential as climate change affects precipitation patterns.
  • Food vulnerability refers to the sensitivity of agricultural yields and import dependencies, as well the capacity to adapt through agricultural resources. Innovations in agriculture can mitigate food insecurity risks due to climate change.

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 Antigua and Barbuda?

In 2020, the gross domestic product (GDP) in Antigua and Barbuda declined by -18.8% from the previous year, with the economy moving from $1.69bn to $1.37bn. During the same period, carbon emissions decreased by -0.65%. Over the ten-year period from 2010 to 2020, GDP grew 19.3%, while emissions increased by 19.8%.

To put this into context, the compound annual growth rate (CAGR) of GDP in Antigua and Barbuda over the past ten years was 1.8%, and the CAGR for greenhouse gas emissions was 1.8%.
