  • The research and consulting firm, Rhodium Group, has released a report on Global Greenhouse Gas Emissions.

Key Findings of the report:

  • Global Greenhouse gas emissions including emissions of all six Kyoto gases have reached 52 gigatons of CO2-equivalent in 2019. This is an 11.4% increase over the past decade.


The six main gases under Kyoto Protocol are:

  • Carbon dioxide (CO2);
  • Methane(CH4);
  • Nitrous oxide(N2O);
  • Hydrofluorocarbons (HFCs);
  • Perfluorocarbons(PFCs);
  • Sulphur hexafluoride (SF6).


  • China alone contributed more than 27% of total Global Greenhouse gas emissions. Further, China’s greenhouse gas emissions in 2019 exceeded the combined emissions of the US and other developed nations.
  • However, China’s history as a major emitter is relatively short compared to developed countries. Since 1750, members of the OECD bloc have emitted four times more CO2 on a cumulative basis than China.
  • The United States is the second-highest emitter. The US alone contributed 11% of the total Global Greenhouse gas emissions.
