Armenia's Sources of N2O Emissions
✨ Key Insights
Agricultural Emissions Dominate
Throughout the decades, Armenia's N2O emissions have been predominantly driven by agriculture. This sector has consistently contributed the largest share of emissions, reflecting the country's agricultural practices. The Sovietization of Armenia in 1920 likely intensified agricultural activities, contributing to increased emissions. However, the data shows a notable decline in agricultural emissions in the 1990s, coinciding with Armenia's independence and the subsequent economic restructuring.
Energy Sector's Growing Influence
The energy sector's contribution to N2O emissions has seen a gradual increase over the years. The completion of the Baku-Batumi railway in 1899 marked the beginning of increased energy consumption, while the construction of the Metsamor Nuclear Power Plant in 1966 and its reopening in 1995 helped reduce reliance on fossil fuels. Despite these efforts, the energy sector's emissions have continued to rise, reflecting ongoing challenges in transitioning to cleaner energy sources.
Impact of International Commitments
Armenia's commitment to international agreements, such as the Kyoto Protocol in 2001 and the Paris Agreement in 2016, underscores its dedication to reducing greenhouse gas emissions. These commitments have likely influenced national policies, promoting renewable energy and energy efficiency. The expansion of renewable energy in 2010 further supports this trend, contributing to a gradual reduction in emissions from energy production.
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 generated using a large language model (LLM) using a structured approach to improve the accuracy. This included separating the context generation from the interpretation and narrative.
