Namibia's Yearly Greenhouse Gas Emissions in CO₂ Equivalent
Key Insights
Agriculture Dominates Namibia’s Footprint
Over the historical record, methane and nitrous oxide from agriculture account for most of Namibia's warming impact-methane contributes over half, and nitrous oxide around a quarter. Land-use CO2 adds roughly a tenth, while fossil-fuel CO2 has been modest and largely oil-led, and fluorinated gases remain tiny. The emissions mix is thus primarily rural and land-based rather than industrial.
Methane Trends And Turning Points
Methane rose gradually from the early 20th century, jumped in the late 1950s to early 1960s, then leveled off before climbing again from the mid‑1980s to today, reaching around 6 megatonnes in recent years. Livestock has been the mainstay throughout. Crop-related methane grew after the 1960s, spiked in the mid‑2000s, and has declined since the early 2010s-tempering, but not reversing, the overall upward path. When emissions slowed in the 1960s-1980s, their warming impact briefly eased before rising again with renewed growth.
Land Use And Nitrous Oxide
CO2 from land use shifted from a slight sink before 1950 to a growing source thereafter, increasing steadily since the mid‑1970s to roughly 5 megatonnes in recent years and varying from year to year. Nitrous oxide shows a similar story: a post‑war surge, a mid‑century pullback, then a gentle rise since the 1970s, now around 3 megatonnes, overwhelmingly from agriculture.
Current Trajectory And Priorities
Today, the dominant sources-methane, nitrous oxide, and land‑use CO2-are generally edging upward or holding near recent highs. Progress in crop methane is encouraging, but livestock methane and agricultural nitrous oxide continue to creep up, and land‑use CO2 has been rising. Bending these trends downward in agriculture and land use will matter most for reducing Namibia's overall warming impact.
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.
- CO2 Fossil Fuels and Industry (CO2 FFI)
- CO2 Land-Use, Land-Use Change and Forestry (CO2 LULUCF)
- 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.

CO2 From Fossil Fuels and Industry
The sources are mostly fossil-fuel combustion emissions from coal, oil, and gas, as well as emissions from industrial processes such as cement production. Cement also absorbs CO2 out of the atmosphere through carbonation, which reduces emissions by about 0.8 Gt per year and is included here.
CO2 From Land-Use, Land-Use Change, and Forestry
The main driver of these emissions is deforestation, which includes logging and forest degradation, as well as other land-use change activities. The emissions also take into account the absorption of CO2 by processes that remove CO2 from the atmosphere, such as afforestation and reforestation. It is the net effect that is indicated here.
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
The last available year in all the emission datasets is 2023. CO2 emissions data is from the Global Carbon Project. It contains national CO2 emissions from fossil sources and land-use change. Emissions from CH4, N2O and F-gases come from the PRIMAP-Hist dataset. It is a rich dataset that combines several published sources to create a historical emissions time series for various greenhouse gases.
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.
