Saint Lucia's Sources of CO₂ Emissions

✨ Key Insights

Early Agricultural Shifts

In the mid-20th century, Saint Lucia experienced a shift in agricultural practices with the introduction of banana cultivation. This transition likely led to increased CO₂ emissions due to deforestation and the use of fertilizers. Although precise emission figures are not available, this change marked a notable impact on the island's greenhouse gas emissions profile.

Oil Terminal and Emissions Rise

The establishment of an oil terminal in 1979 marked a significant development in Saint Lucia's energy landscape. This facility facilitated the import and storage of petroleum products, contributing to a rise in CO₂ emissions from fossil fuel combustion. The impact of this development is reflected in the data, showing a notable increase in emissions during this period.

Tourism and Energy Consumption

The growth of the tourism industry in the late 20th century further increased Saint Lucia's energy consumption and CO₂ emissions. The construction of hotels and infrastructure, along with increased air travel, contributed to higher fossil fuel use. This trend is evident in the data, highlighting the tourism sector's role as a significant source of emissions on the island.

Renewable Energy Initiatives

In the early 21st century, Saint Lucia began adopting renewable energy initiatives to reduce its reliance on fossil fuels. These efforts aimed to decrease CO₂ emissions from energy production, marking a positive step towards sustainable energy practices. While the overall impact on emissions is challenging to quantify, these initiatives represent a significant shift in the island's approach to energy consumption.

Pandemic's Temporary Impact

The COVID-19 pandemic in 2020 led to a temporary reduction in emissions due to decreased tourism and economic activity. This downturn resulted in lower energy consumption, highlighting the impact of economic activity on greenhouse gas emissions. Although the reduction was temporary, it underscored the relationship between economic fluctuations and emissions levels in Saint Lucia.

Background

The chart shows a national breakdown by source of the yearly CO₂ emissions from human activities and processes expressed in megatonnes. It is critical to know and track the sources of national CO₂ emissions in order to understand their individual impacts on climate change.

The sources of human CO₂ emissions are

CO₂ From Fossil Fuels and Industry: coal, oil, gas combustion, other fossil processes
CO₂ From Land-Use, Land-Use Change, and Forestry

Coal, oil and gas combustion

Fossil fuel CO₂ emissions from the combustion of coal, oil and gas are emitted by processes in electricity generation, transport, industry, and the building sector. All processes can be linked to human activities. Examples include driving cars with combustion engines burning diesel or gas, or electric cars charged by electricity from a power plant that burns coal.

Other fossil processes

Fossil CO₂ emissions from other processes include sources like cement manufacturing and production of chemicals and fertilizers. Cement also has an absorption factor highlighted in the absorption breakdown chart.

Land-use change

Human civilization emits CO₂ by changing and managing its land. Those emissions come, for example, from deforestation, logging, forest degradation, harvest activities and shifting agriculture cultivation. Land-use change also absorbs considerable amounts of CO₂, which is shown in the absorption breakdown chart. Land-use change emits more than it absorbs, so the net effect is still emissions, but less than for coal, oil and gas.

Units and Measures

CO₂ emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

About the Data

The last available year is 2023. CO₂ emissions data is from the Global Carbon Project. It contains national CO₂ emissions from fossil sources and land-use change.

The Key Insights paragraph was generated using a large language model (LLM) using a structured approach to improve the accuracy. This included separating the context generation from the interpretation and narrative.
