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.

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.

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.

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.

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.

VIJAYAWADA: Andhra Pradesh has become the first state in the country to come up with an inventory of greenhouse emissions (CGH).

There is a high correlation between urbanisation and the emission of greenhouse gases. Landfills and sewers in cities generate 15% of methane emissions; this sector offers immense possibilities for the mitigation of methane emissions in Asian megacities. Capturing methane by efficiency improvements in the working of both sewage treatment plants and sanitary landfills has co-benefits in terms of both public health as well as mitigating climate change.
