Netherlands' Sources of N2O Emissions
Key Insights
Agricultural Emissions Dominate
Throughout the decades, the Netherlands has seen a significant contribution to N₂O emissions from agriculture. This sector has consistently been the largest source of emissions, peaking in the late 20th century. The implementation of manure management policies in 1990 helped curb these emissions, reflecting a commitment to reducing agricultural pollution. Despite these efforts, agriculture remains a dominant source of N₂O emissions, highlighting the ongoing challenge of balancing agricultural productivity with environmental sustainability.
Industrial Shifts and Emission Trends
The industrial sector in the Netherlands experienced a dramatic rise in N₂O emissions during the mid-20th century, coinciding with the post-war industrial boom. However, the introduction of catalytic converters in 1986 and the closure of coal mines in 1995 marked a turning point, leading to a decline in emissions. These technological and policy shifts underscore the impact of industrial practices on emission trends and the potential for innovation to drive environmental improvements.
Energy Sector's Evolving Role
The energy sector's contribution to N₂O emissions has fluctuated over the decades. The discovery of the Groningen gas field in 1959 and the subsequent shift from coal to natural gas initially increased emissions. However, the Netherlands' participation in the EU Emissions Trading System in 2005 and the promotion of renewable energy in 2000 have helped mitigate these emissions. These efforts reflect the country's ongoing transition towards a more sustainable energy landscape.
Temporary Reductions Amidst Global Events
The COVID-19 pandemic in 2020 led to a temporary reduction in N₂O emissions due to decreased economic activity. This unexpected decline highlights the impact of global events on emission patterns, although the effect was short-lived as activities resumed. The pandemic serves as a reminder of the complex interplay between economic activity and environmental outcomes, emphasizing the need for sustainable practices in the face of global challenges.
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.
