Qatar's Sources of CH4 Emissions

✨ Key Insights

Early Developments in Qatar's Emissions

Qatar's journey in anthropogenic methane emissions began with the discovery of the Dukhan oil field in 1940, marking the onset of its oil industry. This discovery laid the foundation for increased oil extraction and combustion, contributing to the country's CO₂ emissions. However, it wasn't until the discovery of the North Field gas reserve in 1971 that Qatar's methane emissions began to rise significantly. The exploitation of this vast natural gas reserve positioned Qatar as a major player in the global energy market, leading to increased methane emissions from natural gas production and export activities.

Significant Increases in the Late 20th Century

The late 20th century saw a notable rise in Qatar's methane emissions, particularly from fugitive emissions associated with natural gas extraction and processing. The inauguration of LNG export facilities in 1997 marked a significant expansion in Qatar's natural gas industry, contributing to a sharp increase in methane emissions. This period also saw fluctuations in emissions, with some years experiencing significant increases and others witnessing decreases, reflecting the dynamic nature of the energy sector.

Modern Efforts and Challenges

In recent years, Qatar has made efforts to address its emissions through initiatives like the Qatar National Vision 2030 and the ratification of the Paris Agreement in 2015. Despite these commitments, the country's reliance on fossil fuel production and export continues to pose challenges in achieving significant reductions in methane emissions. The North Field Expansion Project, launched in 2022, underscores Qatar's ongoing role in meeting global energy demand, with potential implications for future emissions. As Qatar navigates its path towards sustainable development, balancing economic growth with environmental responsibility remains a critical challenge.

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.
