North Macedonia's Sources of N2O Emissions
Key Insights
Agricultural Dominance and Fluctuations
Throughout the decades, North Macedonia's N2O emissions have been predominantly driven by agriculture. This sector has consistently contributed the largest share of emissions, peaking in the mid-20th century. The post-World War II industrialization period saw a significant rise in emissions, aligning with the establishment of various industries. However, the agricultural sector's emissions have shown notable fluctuations, with significant increases and decreases over the years, reflecting changes in agricultural practices and economic conditions.
Energy Sector's Growing Influence
The energy sector, while initially a minor contributor, has seen a gradual increase in its share of N2O emissions. The opening of the REK Bitola power plant in 1965 marked a pivotal moment, as it significantly boosted coal-based energy production. This shift is evident in the steady rise of emissions from the energy sector, particularly in the latter half of the 20th century. Despite efforts to transition towards renewable energy, the energy sector remains a key player in North Macedonia's emissions profile.
Recent Trends and Policy Impacts
In recent years, North Macedonia has made strides towards reducing its emissions through policy initiatives. The enactment of the Renewable Energy Law in 2010 and the National Climate Change Strategy in 2015 highlight the country's commitment to sustainable development. These efforts aim to curb emissions by promoting renewable energy and improving energy efficiency. The COVID-19 pandemic in 2020 also temporarily reduced emissions due to decreased economic activity, but the long-term impact will depend on the country's recovery trajectory and continued policy implementation.
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.
