CCAC NDC Watch - Pre-COP Review of Non-CO₂ Pollutants in National Climate Plans
The UNFCCC Secretariat recently published a report summarizing information from 64 new nationally determined contributions (NDCs) released up to 30th September 2025. The report highlights tangible progress in addressing climate change worldwide.
Increased Inclusion of Super Pollutants in NDCs
Our analysis shows that countries committed to the Paris Agreement are increasingly incorporating strategies to reduce super pollutants within their NDCs’ greenhouse gas mitigation targets. Compared to NDCs before 2020, the latest plans show:
- A 22% increase in coverage of methane and nitrous oxide
- A 61% rise in coverage of hydrofluorocarbons (HFCs)
Although not explicitly recommended by CCAC guidance, the inclusion of black carbon emissions has doubled. Additionally, measures addressing non-methane tropospheric ozone precursors have tripled, reflecting greater ambition on both fronts.
Quantified Targets and Mitigation Potential Assessments
The number of countries providing quantified targets or evaluating the mitigation potential of pollutants in their NDCs grew notably, from almost none in pre-2020 submissions. Previously, only two NDCs included black carbon in this way.
“As of 30 September, 35 countries include a quantified methane target or assessment of mitigation potential in their latest NDC, while 23 and 9 include HFCs and black carbon in this way respectively.”
Summary
More nations are integrating specific targets and mitigation strategies for super pollutants in their climate plans, signaling progress toward stronger global climate action.
Author’s summary: Countries are increasingly embedding targets for super pollutants like methane, HFCs, and black carbon in their updated climate plans, showing a rising commitment to comprehensive greenhouse gas mitigation.
