Togo's Sources of N2O Emissions
Key Insights
Long-Term Rise Accelerates
Togo's human-related N2O emissions were very low through the early 20th century, then climbed gradually during the post‑war decades. A clearer upswing set in from the early 1980s to around 2010, followed by a marked acceleration in the 2010s. Agriculture alone moved from roughly 1 megatonne around 2010 to about 2 megatonnes in the early 2020s, indicating a strong, steady rise rather than volatile swings.
Agriculture Dominates The Picture
Agriculture accounts for the vast majority of the country's N2O emissions-well over four‑fifths-so its trend largely defines the national picture. Non‑agricultural sources remain small by comparison. Energy and waste have edged up slowly from near‑zero mid‑century to around 0.1 megatonnes each in recent years. "Other" sources increased to a little over 0.1 megatonnes by the late 2000s and have been relatively steady since. Industry is negligible throughout the record.
Outlook For Key Sources
The dominant sector-agriculture-is still rising quickly, driving most of the current increase in N2O climate impact. Reversing this trajectory in agriculture is essential to change the national trend. "Other" sources, while much smaller, appear broadly stable at a little over 0.1 megatonnes; keeping them from drifting upward will help, but the main leverage lies in slowing and ultimately bending down agricultural emissions.
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.

About the Data
The last available year in all the emission datasets is 2023. N2O emissions 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.
