MONTREAL PROTOCOL EFFECT ON GREENHOUSE GASES EMISSIONSS REDUCTION SHOWN TO EQUAL HALF OF US GHG GAS EMISSIONS REDUCTION

03.09.2017

Quantifying the impact of the Montreal Protocol on U.S. GHG (greenhouse gases) emissions with atmospheric observations, a new study has shown that, in terms of CO2-equivalent emissions, the emissions reduction of ozone-depleting substances (ODS) from 2008 to 2014 equaled roughly 50 percent of the reductions achieved by the United States for all GHGs covered by the Kyoto Protocol over the same period.

CFCs and HCFCs are in effect also potent greenhouse gases, with high GWPs, and a long lifetime (for GWP values click here).

Implementation of the Montreal Protocol in the United States led to a near complete phase-out of the consumption of CFCs beginning in 1996 and a 95 percent decline of HCFCs production since 1998. As a result, total emissions of CFCs in the U.S. have decreased by two-thirds from 2008 to 2014, while emissions of HCFCs declined by about half.
Future reduction of ODS emissions will continue to add to GHG emissions reductions, although ODS are not included in the Climate treaties.
