Global Methane Pledge

Global Methane Pledge:

The US President has announced the Global Methane Pledge, which is an US-EU led effort to cut methane emissions by a third by the end of this decade.

  • The announcement has come ahead of 26th Conference of the Parties (COP26) of United Nations Framework Convention on Climate Change (UNFCCC) in Glasgow, UK.
  • This will also help in abiding by the targets of the Paris climate deal.
  • The pact between the US and the EU sets a target of cutting at least 30% from global methane emissions, based on 2020 levels, by 2030.
  • If adopted around the world, this would reduce global heating by 0.2C by the 2040s, compared with likely temperature rises by then.
  • The world is now about 1.2C hotter now than in pre-industrial times.

Methane Gas:

  • Methane is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms (CH4).
  • It is flammable, and is used as a fuel worldwide.
  • Methane is a powerful greenhouse gas.
  • Approximately 40% of methane emitted is from natural sources and about 60% comes from human-influenced sources, including livestock farming, rice agriculture, biomass burning and so forth.
  • More Global Warming Potential: It is nearly 80-85 times more potent than carbon dioxide in terms of its global warming capacity.
  • This makes it a critical target for reducing global warming more quickly while simultaneously working to reduce other greenhouse gases.
  • Promotes Generation of Tropospheric Ozone: Increasing emissions are driving a rise in tropospheric ozone air pollution, which causes more than one million premature deaths annually.
