Global Greenhouse Gas Monitoring Infrastructure (Gggmi) Plan – WMO

Global Greenhouse Gas Monitoring Infrastructure (Gggmi) Plan – WMO

In News: The World Meteorological Organization (WMO) Executive Council has recently endorsed plans for a new Global Greenhouse Gas Monitoring Infrastructure.


  • As per WMO, the increase in CO2 levels from 2020 to 2021 was higher than the average growth rate over the past decade and methane saw the biggest year-on-year jump since measurements started.
  • This infrastructure aims to reduce heat-trapping gases and fill critical information gaps which will provide vital information and support for implementation of the Paris Agreement.

Key Points:

  • The proposed GHG monitoring infrastructure will provide sustained delivery of consolidated, top-down, monthly, global estimates of net GHG fluxes into and out of the atmosphere.
  • It will provide critical and timely input to the global stocktake, work program for scaling up mitigation ambition and implementation, IPCC assessment reports, enhanced transparency framework, and national inventories.
  • Greenhouse gas monitoring will help in improving scientific understanding of the Earth System which is in urgent need for scientific underpinning of mitigation actions.
  • In its initial configuration, it is envisaged that the Greenhouse Gas Monitoring Infrastructure will consist of four main components.
  • Output will produce gridded net monthly fluxes of CO2, CH4 and N2O at the special resolution of 100 km by 100 km with a minimum possible delay.
  • CO2 remains in the atmosphere for many decades while methane is more potent but has a shorter life-span of about 10 years.
