Poland's Sources of CH4 Emissions
✨ Key Insights
Industrial Growth and Emission Rise
Poland's industrial journey began in the mid-19th century with the Industrial Revolution, which marked the onset of significant methane emissions due to increased coal mining and usage. The post-World War I era saw Poland regaining independence, leading to further industrial and economic development. This period was characterized by a rise in methane emissions, particularly from livestock and fuel combustion, as the country focused on rebuilding and expanding its infrastructure.
Post-War Reconstruction and Emission Peaks
The aftermath of World War II brought about extensive reconstruction in Poland, significantly increasing methane emissions. The establishment of major industrial facilities, such as the Nowa Huta steel mill in 1952, further contributed to this rise. By the 1960s and 1970s, the expansion of the coal industry led to a peak in emissions, with fugitive emissions from coal mining becoming a dominant source.
Economic Transition and Emission Decline
The 1980s and 1990s marked a turning point as Poland transitioned to a market economy. This shift led to industrial restructuring and a temporary decrease in methane emissions. The adoption of the Kyoto Protocol in 1997 and Poland's accession to the European Union in 2004 further reinforced efforts to reduce emissions, promoting cleaner energy sources and improving energy efficiency.
Renewable Energy and Recent Trends
In recent years, Poland has made strides in renewable energy development, particularly in the 2010s, which has contributed to a gradual reduction in methane emissions. The commitment to the Paris Agreement in 2015 and the hosting of the COP24 climate conference in 2018 underscored Poland's dedication to reducing greenhouse gas emissions. The COVID-19 pandemic in 2020 and subsequent energy policy updates have further influenced emission trends, with recent plans to close coal mines in 2022 marking a significant step towards a cleaner energy future.
Background
The chart shows a national breakdown by source of the yearly methane (CH4) emissions from human activities expressed as weight in megatonnes (Mt). In the scientific literature, these are referred to as anthropogenic emissions. Human-induced methane emissions increase atmospheric methane, which is warming the Earth. The sources of human methane emissions are
- Livestock
- Fugitive emissions from the fossil fuel industry
- Crop production
- Fossil fuel combustion
- Waste management
- Other processes
Methane's Global Warming Potential
Methane has a much higher Global Warming Potential (GWP) than CO2. However, the effect lasts only for a relatively brief period (9 years on average), compared to hundreds of years for CO2. A reduction in emissions can cause a rapid decline in its atmospheric levels and climate impact.
Livestock
Livestock emits methane that is produced in the animals' digestive system. Most methane is emitted from the mouth during rumination. A much smaller amount of methane is emitted from the manure. Depending on how the manure is managed, i.e., wet or dry, more methane is emitted. Wet management leads to higher methane emissions than dry management. However, dry management also emits nitrous oxide (N2O), which is another potent greenhouse gas.
Fugitive emissions from fossil fuel industry
Fugitive methane emissions are from the intentional and accidental release of methane, which happens during the extraction, storage, and transportation processes in the fossil fuel industry. Examples are methane leaks during oil and gas handling, storage, transport, incomplete combustion, and many more. Also, methane is deliberately ventilated from mines during the extraction of coal.
Methane is a primary part of “gas”, also called “natural gas” or “fossil gas”. Natural gas is used, for example, for heating and electricity generation, whereby it emits CO2 during the combustion process. However, when natural gas leaks (unburned) it contains a lot of fugitive methane emissions.
Waste
Waste from landfills and wastewater produces a lot of methane when biodegradable material breaks down without oxygen.
Crop production
Crop production emissions are largely from rice cultivation, which generates large amounts of methane during plant growth. These emissions are from flooded paddies, which create the swamp-like environment of rice fields. There are agricultural techniques to reduce emissions significantly, like periodic drainage and aeration. Rice is the main staple for about half the world's population, and its emissions are a significant part of total human methane emissions.
Fuel combustion
Fuel combustion emissions are mostly from the incomplete combustion of fossil fuels. As mentioned before, natural gas consists largely of methane, and when the combustion does not happen completely, methane enters the atmosphere.
Other
Other human-induced methane emissions include industrial processes and product uses.

Units and Measures
CH4 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. Methane 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.
