Vanuatu's Sources of CO2 Emissions
Key Insights
Colonial Impact on Emissions
The establishment of the British-French Condominium in 1906 marked the beginning of significant colonial activities in Vanuatu, then known as the New Hebrides. This period saw the introduction of livestock farming, which likely contributed to a rise in methane emissions. Although exact figures are unavailable, the increase in livestock numbers would have had a measurable impact on the country's overall emissions profile.
Independence and Land-Use Changes
Vanuatu's independence in 1980 brought about shifts in land-use policies and economic activities. The new government focused on developing agriculture, which may have led to changes in land use and increased emissions due to deforestation and agricultural expansion. This period likely saw a rise in CO₂ emissions as the country sought to establish its economic footing.
Cyclones and Emission Fluctuations
Natural disasters, such as Cyclone Ivy in 1994 and Cyclone Pam in 2015, have also played a role in Vanuatu's emissions history. These cyclones caused significant damage to forests and vegetation, leading to temporary increases in CO₂ emissions from decomposing organic matter. The reconstruction efforts following these events further contributed to emissions, highlighting the vulnerability of Vanuatu's environment to extreme weather events.
Renewable Energy Initiatives
In 2005, Vanuatu began implementing renewable energy projects to reduce its reliance on fossil fuels. This transition likely led to a decrease in CO₂ emissions, as the country embraced solar and wind energy. These initiatives represent a positive step towards sustainable development and a reduction in the country's carbon footprint.
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.
