Honduras' Yearly Greenhouse Gas Emissions in CO₂ Equivalent
Key Insights
2024 Emissions Profile
In 2024, CO2 was Honduras's largest source at around 22.9 megatonnes CO2, or 64.7% of the national total, declining by about 1.9% per year over the ten years to 2024. Methane contributed around 8.8 megatonnes CO2e (25.0%) and rose by 0.9% per year; nitrous oxide was about 2.7 megatonnes CO2e (7.6%), rising by 0.5% yearly. F-gases were the smallest source, at roughly 0.9 megatonnes CO2e (2.7%), but grew by about 9.2% per year.
Historic Carbon Dioxide (CO2) Emissions
CO2 emissions began at roughly 8.8 megatonnes CO2 in 1851, fluctuating and falling to around 4.1 megatonnes CO2 in 1893 before reaching about 6.1 in 1911. They then surged to a record roughly 68.7 megatonnes CO2 in 1959, fell sharply, and varied widely thereafter. Emissions were around 22.9 megatonnes CO2 in 2024.
Historic Methane (CH4) Emissions
Methane emissions started at about 0.5 megatonnes CO2e in 1851 and rose steadily through the twentieth century, reaching nearly 5.9 in the mid-1980s. They eased slightly through the 1990s before climbing again to their record of around 8.8 megatonnes CO2e in 2024. Methane's warming contribution since 1851 was around 70% 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 began near 0.03 megatonnes CO2e in 1851 and remained very low into the early twentieth century. They increased more rapidly after the 1940s, rising from around 0.2 to 1.7 megatonnes CO2e by the mid-1990s. Emissions peaked at roughly 3.0 megatonnes CO2e in 2020 and stood at about 2.7 in 2024.
Historic Fluorinated Gases (F-gases) Emissions
F-gas emissions were effectively zero through most of the record, reaching only around 0.01 megatonnes CO2e in 1995. They then rose to roughly 0.5 megatonnes CO2e by 2016 and accelerated afterwards. F-gas emissions reached their highest level, around 0.9 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.

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.

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.
