Gambia's Yearly Greenhouse Gas Emissions in CO₂ Equivalent

Key Insights

2024 Emissions Profile

In 2024, CO2 was Gambia's largest source at around 1.4 megatonnes CO2, or 49% of the national total, rising by about 1.8% per year over the ten years to 2024. Methane accounted for around 1.2 megatonnes CO2e (41%) and fell by roughly 3.0% per year. Nitrous oxide contributed about 0.3 megatonnes CO2e (10%), declining by around 2.4% per year. Emissions were therefore divided mainly between CO2 and methane, with nitrous oxide a smaller component.

Historic Carbon Dioxide (CO2) Emissions

CO2 emissions were low for much of the period before the mid-1980s, but varied markedly, reaching roughly 1.2 megatonnes CO2 in the early 1970s before falling back. They then generally increased, despite a brief net-negative level in the early 1990s, peaking at around 3.7 megatonnes CO2 in 2007. By 2024, emissions were around 1.4 megatonnes CO2.

Historic Methane (CH4) Emissions

Methane emissions began at around 0.15 megatonnes CO2e in 1851 and rose gradually through the first half of the twentieth century. Growth continued after the late 1940s and accelerated after the early 2000s, reaching a peak of roughly 1.6 megatonnes CO2e in 2015. They then declined to around 1.2 megatonnes CO2e in 2024. Methane's warming contribution since 1851 was around 71% larger than its emissions alone suggest, because methane's short atmospheric lifetime amplifies the warming impact when CH4 emissions are rising.

Historic Nitrous Oxide (N2O) Emissions

Nitrous oxide emissions started near zero, at around 0.008 megatonnes CO2e in 1851, and rose slowly into the early twentieth century. They increased more substantially from the 1930s, peaking at roughly 0.4 megatonnes CO2e in 2010. Emissions then declined through the following years, reaching around 0.3 megatonnes CO2e in 2024.

Background

Greenhouse gas emissions from human activities are the main drivers of human-induced warming. In the scientific literature, human-induced emissions are often referred to as anthropogenic emissions.

  • Carbon Dioxide (CO2)
  • Methane (CH4)
  • Nitrous oxide (N2O)
  • Fluorinated gases (F-gases)

Emissions from all different gases are expressed in CO2-equivalent units to make it possible to compare the relative emissions from these different gases. CO2-equivalents are calculated using the global warming potentials of the respective gases, in this case using a 100-year time horizon.

Total Historic Share

Emissions from all different gases are expressed in CO2-equivalent units to make it possible to compare the relative emissions from these different gases. CO2-equivalents are calculated using the global warming potentials of the respective gases, in this case using a 100-year time horizon.

Crabon Dioxide (CO2)

CO2 includes emissions from fossil fuels and industry (FFI), and from land-use, land-use-change, and forestry (LULUCF).

Methane (CH4)

Methane emissions are caused by human activities such as rearing livestock, agricultural practices, and fugitive fossil fuel emissions.

Nitrous Oxide (N2O)

Common sources of these emissions are fossil fuel emissions and the agricultural use of synthetic fertilizer and manure.

Fluorinated Gases (F-gases)

Fluorinated gases are a group of gases defined by UNFCCC: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). Fluorinated gases are also known as halogenated gases.

Units and Measures

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

About the Data

National CO2 emissions data through 2024 is from the Global Carbon Project and covers fossil sources and land-use change. Emissions data through 2024 for CH4, N2O and F-gases comes from the PRIMAP-hist dataset, which combines several published sources into 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.
