Cabo Verde's Sources of CH4 Emissions
Key Insights
2024 CH4 Emissions Profile
In 2024, Cabo Verde's methane emissions totalled around 0.154 megatonnes CO2e. Livestock was the largest source, at around 0.066 megatonnes CO2e (42.6%), narrowly ahead of waste at 0.061 megatonnes CO2e (39.9%). Fuel combustion contributed 0.024 megatonnes CO2e (15.5%), while fugitive emissions were 0.002 megatonnes CO2e (1.3%). Over the ten years to 2024, waste and fuel combustion rose, livestock changed little, and fugitive emissions declined.
Historic Livestock Emissions
Livestock emissions began at around 0.006 megatonnes CO2e in 1851 and rose gradually through the mid-1960s, reaching roughly 0.024 megatonnes CO2e. After some variation through the 1970s and early 1980s, they climbed sharply to around 0.054 megatonnes CO2e in 1992. Emissions peaked at roughly 0.066 megatonnes CO2e in 2016 and ended at around 0.066 megatonnes CO2e in 2024.
Historic Fugitive Emissions
Fugitive emissions were negligible through most of the period before the late 1980s, reaching around 0.003 megatonnes CO2e in 1988. They then rose rapidly to around 0.034 megatonnes CO2e by 1993, before varying and peaking at roughly 0.056 megatonnes CO2e in 2000. They subsequently declined substantially, ending at around 0.002 megatonnes CO2e in 2024.
Historic Waste Emissions
Waste emissions started at around 0.007 megatonnes CO2e in 1851 and increased gradually to roughly 0.019 megatonnes CO2e by the early 1950s. They remained broadly stable, with modest fluctuations, until the late 1980s. From 1988, emissions rose strongly from around 0.019 megatonnes CO2e, reaching their peak of roughly 0.061 megatonnes CO2e in 2024.
Historic Fuel Emissions
Fuel combustion emissions were near zero until the early 1940s. They rose gradually thereafter, reaching around 0.017 megatonnes CO2e by 1995, then increased to a peak of roughly 0.026 megatonnes CO2e in 2001. Emissions subsequently fluctuated at lower levels, falling to around 0.018 megatonnes CO2e in 2018 before ending at about 0.024 megatonnes CO2e in 2024.
Background
The chart shows a national breakdown by source of the yearly methane (CH4) emissions from human activities expressed as weight in megatonnes (Mt). In the scientific literature, these are referred to as anthropogenic emissions. Human-induced methane emissions increase atmospheric methane, which is warming the Earth. The sources of human methane emissions are
- Livestock
- Fugitive emissions from the fossil fuel industry
- Crop production
- Fossil fuel combustion
- Waste management
- Other processes
Methane's Global Warming Potential
Methane has a much higher Global Warming Potential (GWP) than CO2. However, Methane emissions in the atmosphere decay with an average lifetime of about 12 years so its long term warming-effect is much less compared to CO2 which stays on average for hundreds of years in the atmosphere. Meaning: Methane's short term warming effect is much higher, but long term warming effect is much lower. A reduction in emissions can cause a rapid decline in its atmospheric levels.
Livestock
Livestock emits methane that is produced in the animals' digestive system. Most methane is emitted from the mouth during rumination. A much smaller amount of methane is emitted from the manure. Depending on how the manure is managed, i.e., wet or dry, more methane is emitted. Wet management leads to higher methane emissions than dry management. However, dry management also emits nitrous oxide (N2O), which is another potent greenhouse gas.
Fugitive emissions from fossil fuel industry
Fugitive methane emissions are from the intentional and accidental release of methane, which happens during the extraction, storage, and transportation processes in the fossil fuel industry. Examples are methane leaks during oil and gas handling, storage, transport, incomplete combustion, and many more. Also, methane is deliberately ventilated from mines during the extraction of coal.
Methane is a primary part of “gas”, also called “natural gas” or “fossil gas”. Natural gas is used, for example, for heating and electricity generation, whereby it emits CO2 during the combustion process. However, when natural gas leaks (unburned) it contains a lot of fugitive methane emissions.
Waste
Waste from landfills and wastewater produces a lot of methane when biodegradable material breaks down without oxygen.
Crop production
Crop production emissions are largely from rice cultivation, which generates large amounts of methane during plant growth. These emissions are from flooded paddies, which create the swamp-like environment of rice fields. There are agricultural techniques to reduce emissions significantly, like periodic drainage and aeration. Rice is the main staple for about half the world's population, and its emissions are a significant part of total human methane emissions.
Fuel combustion
Fuel combustion emissions are mostly from the incomplete combustion of fossil fuels. As mentioned before, natural gas consists largely of methane, and when the combustion does not happen completely, methane enters the atmosphere.
Other
Other human-induced methane emissions include industrial processes and product uses.

Units and Measures
CH4 emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

National methane emissions data through 2024 is from the PRIMAP-hist dataset, which combines several published sources into a historical emissions time series.
The Key Insights paragraph was created using a large language model (LLM) in combination with our data, historic events, and a structured approach for best accuracy by separating the context generation from the interpretation and narrative.
