The Superpollutant Mitigation Measures Catalogue: 200+ ways to cut methane, HFCs, black carbon, N2O, and tropospheric ozone.
The Superpollutant Mitigation Measures Catalogue is intended to make it easier for companies, investors, and policymakers to see not just what can be done, but how to act on it. You can filter and sort using the icons at the top of the table. Definitions for each field are below the table; and more information about how this was developed can be found in Appendix B of the Roadmap (download here).
The CC Lab intends to continuously expand, refine, and update this database, adding examples and providing even more information on each.
We look forward to learning about and featuring additional measures and data. As you explore the data, let us know if you have measures, sources, updates, or examples to add, contact us at: superpollutants@cclab.org
Superpollutant Mitigation Measures Catalogue
Field Definitions
| Mitigation Measure | A physical measure taken to mitigate superpollutants (not a financing, policy, or enabling mechanism). |
|---|---|
| Source Type | A classification of the main sources of superpollutants to align with the IPCC Guidelines for National Greenhouse Gas Inventories. In some cases these are tailored to describe the sub-sector most closely tied to the mitigation measure. |
| Primary Superpollutant | The primary gas being mitigated through the measure |
| Other Superpollutants Addressed | Other superpollutants mitigated through the measure in addition to the primary superpollutant |
| Maturity Level | A value between one and six indicating how developed, reliable, and ready a technology or process is for widespread use. Each level is further defined below. |
| Voluntary Carbon Markets Status | Availability of methodologies in the Voluntary Carbon Market which incentivise this measure. Active indicates one or more active methodologies; Inactive indicates methodologies that have been retired or invalidated; In development indicates methodologies in progress; Not Available indicates a lack of all of the above. |
| Value Chain Market Mechanism | This column shows which market-based value chain actions might be appropriate for the measure, including: a standard existing for an EAC or book-and-claim system; a standard is in development; the activity is well suited to supplier engagement; or the activity is unlikely to be suited to these mechanisms. |
Maturity Level Definitions
| Maturity Level | Activities at this Maturity Level | Mechanism of Corporate Action | Example Strategic Corporate Action |
|---|---|---|---|
| 1Concept & Research | Laboratory-scale testing, academic research, and theoretical modeling. Low Technology Readiness Level (TRL 1–3); high financial and technical risk. |
|
Fund university labs or early-stage accelerators directly to prove basic chemistry and unlock the intellectual property needed for new tech. |
| 2Proof of Concept | Small pilot plants, prototype modeling, and life-cycle assessment (LCA) projections. Medium-low readiness (TRL 4–6); economic viability unproven. |
|
Invest seed equity through CVC arms to build early prototype hardware. Provide an active physical corporate asset to host the first field pilot. |
| 3Demonstration & Early Deployment | First-of-a-kind commercial projects, early regulatory approvals, and niche adoption. Medium-high readiness (TRL 7–8); relies on subsidies, grants, or early adopters. |
|
Invest direct equity into first-of-a-kind (FOAK) infrastructure facilities. Back this with a VCM Forward Offtake contract to guarantee an anchor customer. |
| 4Early Adoption & Capital Chasm | Early-stage commercial rollout, limited to a few pioneering projects globally; focus on reducing high initial capital expenditures. TRL 8–9. Chasm because standard commercial banks view it as too risky, requiring specialized infrastructure funds, private equity, or loan guarantees. |
|
Purchase issued spot market credits from already-established projects to offset immediate corporate footprint gaps while long-term infrastructure scales up. |
| 5Scaling/ Commercialization | Mass manufacturing, standardized supply chains, declining unit costs, and policy backing. Mature (TRL 9); Some standard commercial financing available. |
|
Use procurement mandates and low-interest supply-chain financing to force smaller tier-1 and tier-2 partners to adopt mature, off-the-shelf upgrades. |
| 6Optimization & System Integration | Continuous technological refinement, circular-economy recycling of materials, and fully integrated grid/infrastructure support. |
|
Lobby for codes, mandates, and bans/standards to turn proven Level 5 solutions into mandatory, industry-wide legal requirements. |
