A global methane model for rice cropping systems: final report

It has been estimated that rice production accounts for up to 55% of the total greenhouse gas (GHG) emissions budget from agricultural soils. Finding efficient ways to mitigate these emissions without adversely impacting yield is crucial as rice is a major cereal crop for half of the world’s population and …

Global Warming Potential (GWP): understanding the implications for mitigating methane emissions in agriculture

Agricultural GHG emissions are predominately in the form of CH4, nitrous oxide (N2O), CO2, and black carbon. Methane and black carbon are both SLCPs. Black carbon emissions can be caused by the burning of biomass (such as crop residues) and from incomplete combustion of fossil fuels. Cold-chain logistics – part …

Global methane assessment: benefits and costs of mitigating methane emissions

The assessment highlights the critical role that cutting methane emissions, including from the fossil fuel industry, plays in slowing the rate of global warming. Cutting human-caused methane by 45% this decade would keep warming beneath a threshold agreed by world leaders. There are multiple benefits to acting including: the rapid …

Coal mine methane on the brink

A frenzy of new mine projects and proposals in some of the world’s gassiest coal seams could emit enough methane to rival the current CO2 emissions from coal plants in the United States, according to new data and modeling from Global Energy Monitor. In a first-of-its-kind analysis, GEM has modeled …

Driving down methane leaks from the oil and gas industry

Reducing methane emissions from oil and gas operations is among the most cost-effective and impactful actions that governments can take to achieve global climate goals. There is a major opportunity for countries looking to develop policies and regulations in this area to learn from the experience of jurisdictions that have …

WMO Greenhouse Gas Bulletin (GHG Bulletin): The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2018

Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization. This continuing long-term trend means that future generations will be confronted with increasingly severe impacts of climate change, including rising temperatures, more extreme weather, water stress, sea level rise and …

Global distribution of methane emissions, emission trends, and OH concentrations and trends inferred from an inversion of GOSAT satellite data for 2010–2015

We use 2010–2015 observations of atmospheric methane columns from the GOSAT satellite instrument in a global inverse analysis to improve estimates of methane emissions and their trends over the period, as well as the global concentration of tropospheric OH (the hydroxyl radical, methane's main sink) and its trend. Our inversion …

Inconvenient truth of climate change

What can we do as temperatures increase and weather changes to bring devastation in different parts of the world? The question no longer is if climate change is real. The question is: What can we do as temperatures increase and weather changes to bring devastation in different parts of the …

The potential for low-carbon renewable methane in heating, power, and transport in the Netherlands

This study presents the production potential for renewable methane in the Netherlands in 2050. The Netherlands is in the process of developing the domestic energy and gas infrastructure policies necessary to comply with both the recast Renewable Energy Directive (RED II) and the country’s Paris Agreement commitments. This study provides …

The greenhouse gas impacts of increased US oil and gas production

Increased oil and natural gas production in the United States has decreased domestic natural gas prices and global oil prices, with major economic and environmental consequences. The resulting greenhouse gas (GHG) impacts have received substantial attention, with most focus on natural gas and relatively little on oil. In this paper, …

Black Soldier Fly biowaste treatment – Assessment of global warming potential

Cities of low and middle-income countries face severe challenges in managing the increasing amount of waste produced, especially the organic fraction. Black Soldier Fly (BSF) biowaste treatment is an attractive treatment option as it offers a solution for waste management while also providing a protein source to help alleviate the …

Integrating short-lived climate pollutants into Asian NDCs: a survey with recommendations

Much of Asia has significant potential to achieve cleaner air and control near-term climate change by integrating short-lived climate pollutants (SLCPs) into their Nationally Determined Contributions (NDCs). This paper analysed NDCs from Northeast, Southeast ans South Asia to determine which countries are capitalising on that potential. The analysis reveals that …

Nigeria’s National Action Plan to reduce short-lived climate pollutants

The Federal Executive Council of Ministers approved in May 2019 Nigeria’s National Action Plan to reduce short-lived climate pollutants. This plan, developed by the the Federal Ministry of Environment of Nigeria, aims to improve air quality and reduce Nigeria’s contribution to climate change, through 22 specific mitigation measures in 8 …

WMO greenhouse gas bulletin (GHG Bulletin): the state of greenhouse gases in the atmosphere based on global observations through 2017

Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization (WMO). There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather. The WMO Greenhouse Gas …

The potential for low-carbon renewable methane as a transport fuel in France, Italy, and Spain

Renewable methane could conceivably displace natural gas for use in existing vehicle fleets, reducing greenhouse gas (GHG) emissions as well as emissions of air pollutants like NOx. It is important that policy makers assess the realistic potential for renewable methane. The technical potential for renewable methane production may vary considerably …

Low-emission cows: farming responds to climate warning

If individual cows that produce less methane could be bred with each other, it could bring down emissions, researchers say. Photograph: Alamy From low-emission cows to robotic soil management, the farming industry will have to explore new approaches in the wake of a UN warning that the world needs to …

Strengthening Nationally Determined Contributions to catalyze actions that reduce short-lived climate pollutants

Early and ambitious action to reduce short-lived climate pollutants (SLCPs) is essential to achieving the goals of the Paris Agreement and the Sustainable Development Goals. SLCPs include methane, hydrofluorocarbons, black carbon, and tropospheric ozone. Actions to reduce these highly potent pollutants help avoid crossing important thresholds, such as a 1.5°C …

Rice farming up to twice as bad for climate change as previously thought, study reveals

Rice farming is known to be a major contributor to climate change, but new research suggests it is far bigger a problem than previously thought. Techniques intended to reduce emissions while also cutting water use may in fact be boosting some greenhouse gases, meaning the impact of rice cultivation may …

Everyday plastics emit greenhouse gases, scientists say

Plastic used in everyday objects from bottles to packaging emit greenhouse gases when exposed to sunlight, according to a study released on Wednesday, as global concern about its impact on the world's oceans grows. Plastic pollution has come under increased scrutiny from environmentalists as the scale of the problem has …

Essar under watch over 'illegal' coal-bed methane extraction in West Bengal

The issue is similar to a dispute between Oil and Natural Gas Corporation and Reliance Industries over the latter drawing gas from the state-run company's block Essar Oil & Gas Exploration and Production (EOGEPL), India’s largest coal-bed methane (CBM) producer, is under the government’s scanner for allegedly drawing gas outside …
