Libya's Sources of N2O Emissions
Key Insights
2024 N2O Emissions Profile
In 2024, Libya's anthropogenic N2O emissions totalled around 1.9 megatonnes CO2e. Agriculture was the largest source, at about 1.2 megatonnes CO2e, or 63.7% of the national total, rising by around 0.003 megatonnes CO2e per year over the ten years to 2024. Other sources contributed 0.31 megatonnes CO2e (16.4%) and declined slightly, while energy rose to 0.27 megatonnes CO2e (14.3%). Waste accounted for 0.10 megatonnes CO2e (5.2%) and also increased.
Historic Agriculture Emissions
Agricultural emissions began at around 0.02 megatonnes CO2e in 1851 and remained low through the early twentieth century, reaching about 0.1 by 1935. They then rose substantially, peaking at roughly 1.3 megatonnes CO2e in 2013, before easing to around 1.2 megatonnes CO2e in 2024.
Historic Energy Emissions
Energy emissions started near 0.007 megatonnes CO2e in 1851 and increased gradually to around 0.03 by 1934. They rose and fluctuated thereafter, reaching roughly 0.15 megatonnes CO2e in 1970 before falling back. Emissions then climbed steadily, reaching their record high of about 0.27 megatonnes CO2e in 2024.
Historic Waste Emissions
Waste emissions were close to zero in 1851, at around 0.001 megatonnes CO2e, and remained small until the late 1950s. They rose to a peak of roughly 0.07 megatonnes CO2e in 2000, then declined to around 0.03 by 2008. They subsequently increased to about 0.10 megatonnes CO2e in 2024.
Historic Other Emissions
Other emissions began at around 0.02 megatonnes CO2e in 1851 and changed little until the late 1960s. They then rose rapidly to about 0.36 megatonnes CO2e in 2009. After dipping to roughly 0.25 in 2011, emissions peaked at around 0.38 in 2014 and ended at about 0.31 megatonnes CO2e in 2024.
Background
The chart shows a national breakdown by source of the yearly nitrous oxide (N2O) emissions from human activities and processes, expressed as weight in megatonnes (Mt). Human-induced emissions are the main driver of the increasing atmospheric nitrous oxide that is warming our planet. The sources of human nitrous oxide emissions are
- Agriculture
- Energy
- Industry
- Waste
- Other
Agriculture
Emissions related to agriculture are mainly from the use of synthetic fertilizers and manure management.
Synthetic fertilizer, used for agricultural processes, contains a lot of nitrogen. That nitrogen in the soil reacts and causes considerable N2O emissions. The use of excess fertilizer, meaning more fertilizer than the plants can use to grow, causes even higher relative emissions. Applying the right amount of fertilizer at the right time can reduce N2O emissions. There are many technical solutions to reduce emissions while keeping, or even increasing, agricultural yields.
When manure is left on the field or otherwise managed in dry processes, it emits considerable amounts of nitrous oxide. Manure can be managed by wet processes, which reduces nitrous oxide emissions but increases methane emissions. Some technical solutions focus on modifying the animal feed to reduce the nitrogen in the manure, thereby reducing nitrous oxide emissions.
Energy, Industry, Waste, and Other
All non-agricultural categories together have much lower emissions than agricultural emissions alone.
N2O emissions related to energy are almost all from the combustion of fossil fuels. For example, the combustion of fossil fuels in power plants, cars, and airplanes not only causes CO2 emissions but also emits nitrous oxide (N2O). Any advances to reducing fossil fuel dependency will thus also reduce nitrous oxide emissions.
Most industry-related emissions are from the chemical industry for producing fertilizer, nylon, and similar products. Technologies are available to reduce emissions in these processes.
Nitrous oxide emissions from waste come from, for example, wastewater treatment and landfills.

Units and Measures
N2O emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

National N2O 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.
