This year’s annual report highlights the pollution trends for the four main pollutants targeted by the Coalition – methane, tropospheric ozone, black carbon and hydrofluorocarbons (HFCs). Using data from the International Institute for Applied Systems Analysis’s (IIASA) latest GAINS model the report looks at historical and projected emissions trends and mitigation scenario toward 2030 through rapid and full implementation of key reduction measures.
The methane emissions trends, for example, show that, while emissions are still on the rise, significant reductions can be made by 2030 if reduction measures are rapidly implemented especially in the agriculture, fossil fuels and waste sectors. In North America and Europe, which combined together make for the most emitting region in 2015full implementation of methane measures would see a reduction of approximately 60 million metric tonnes by 2030 compared to a business-as-usual scenario.
The CCAC is the only global initiative directly targeting black carbon and since 2012 it has increased political will to reduce this dangerous air pollutant. Putting in place short-lived climate pollutant mitigation measures, especially in the household energy, transport, industry and agriculture sectors, can reduce global black carbon emissions by over 60% by 2030 as compared to 2015 emissions. In East and Southeast Asia and the Pacific, the main emitting region in 2015, emissions can be reduced by over 50% compared to business-as-usual if measures are fully implemented.
Efforts by Coalition partners to push for an amendment to phase-down HFCs under the Montreal Protocol and the subsequent adoption of the Kigali Amendment, now ratified by 14 CCAC countries, will see HFC emissions peak by 2025 before falling considerably by 2050. The Coalition was recently rewarded for its efforts to pass the Kigali Amendment with an Ozone Award for Political Leadership at the 30th anniversary meeting of the Parties to the Montreal Protocol.
