Definition: Methane emissions are those stemming from human activities such as agriculture and from industrial methane production. World and regional statistics, national data, maps and rankings, Discover new signals and insights from leading alternative and fundamental data providers, Latest releases of new datasets and data updates from different sources around the world. , Sources of methane gas in earth's atmosphere. Biogenic methane is actively produced by microorganisms in a process called methanogenesis.  The methane itself enables a direct radiative forcing that is second only to that of carbon dioxide (CO2). Reducing methane emissions by capturing and utilizing the gas can produce simultaneous environmental and economic benefits. Methane emissions are those stemming from human activities such as agriculture and from industrial methane production. Plant agriculture, including both food and biomass production, constitutes a fourth group (15%), with rice production being the largest single contributor. Our Insights blog presents deep data-driven analysis and visual content on important global issues from the expert data team at Knoema.  During year 2019, about 360 million tons (60 percent) of methane were released globally through human activities, while natural sources contributed about 230 million tons (40 percent). Integrate your data with the world’s data in a personalized and collaborative environment, purpose-built to support your organizational objectives.

Source: European Commission, Joint Research Centre (JRC)/Netherlands Environmental Assessment Agency (PBL). Including both the direct and indirect forcings, the increase in atmospheric methane is responsible for about one-third of near-term climate warming. 14,984.9. Under certain conditions, the process mix responsible for a sample of methane may be deduced from the ratio of the isotopes of carbon, and through analysis methods similar to carbon dating. Natural sources have always been a part of the methane cycle. Assessing these and other environmental threats to the sustainability of human civilization are topics within Earth system science, including the recently proposed comprehensive framework of planetary boundaries.  The magnitude of this transfer exceeds that from any other known geologic event throughout all of human history. Wetland emissions have been declining due to draining for agricultural and building areas.  When such interactions occur, longer-lived and less-potent CO2 is also produced. They were placed on your computer when you launched this website. In total, humans extracted about 400 billion tons (gigatonnes or petagrams) of geologic carbon through year 2015; including half in just the last one-third century.  Reducing methane emissions by capturing and utilizing the gas can produce simultaneous environmental and economic benefits. Quick data summaries and visualizations on trending industry, political, and socioeconomic topics from Knoema’s database.

Cambodia.  However in August 2020, the U.S. Environmental Protection Agency rescinded a prior tightening of methane emission rules for the U.S. oil and gas industry. Methane emissions (kt of CO2 equivalent) - Country Ranking. 4,494.9.  Contributions from the surviving wild populations of ruminant mammals are vastly overwhelmed by those of cattle, humans, and other livestock animals. Replacing all atmospheric methane with CO2 would reduce total greenhouse gas warming by approximately one-sixth. The description is composed by our digital data assistant. , The world's wetlands contribute about three-quarters (75%) of the enduring natural sources of methane. , In March 2020, Exxon called for stricter methane regulations, which would include detection and repair of leaks, minimization of venting and releases of unburned methane, and reporting requirements for companies. Search and explore the world’s largest statistical database to find data. 20,476.5. Please update this to reflect recent events or newly available information.  Powerful fans could push air through reactors of zeolite and catalysts to absorb the methane. Curated by Knoema’s data analysts to deliver leading short-term and long-term indicators and forecasts from trusted sources for each of the covered industries. , To compare the warming to that from carbon dioxide over a given time period, methane in the atmospheric has an estimated 20-year global warming potential (GWP) of 85, meaning that a ton of CH4 emitted into the atmosphere creates approximately 85 times the atmospheric warming as a ton of CO2 over a period of 20 years.
