New Buyer Coalition Aims to Fast-Track Global Super-Pollutant Mitigation

Efforts to curb the world’s most environmentally harmful gases are gaining new momentum as a group of carbon market professionals puts forward plans for a buyer-led alliance dedicated to super-pollutant mitigation. These high-impact substances—methane, nitrous oxide, and hydrofluorocarbons (HFCs)—have far greater warming potential than CO₂ and together contribute an estimated 45% of current global temperature rise, according to the group behind the proposal.

The planned alliance, the Super Pollutant Education and Credit Transaction Alliance (Spectra), is being initiated by Jason Grillo, co-founder of the US-based carbon removals network AirMiners. He is joined by adviser Tyler Marcus, client lead at consultancy GBB Strategy, along with support from the Climate Agency, a non-profit that works with emerging green solution ventures.

Spectra launched a public consultation on 2 December to refine its strategic roadmap and is actively seeking founding members. Interest is expected from industries where super-pollutant reduction technologies can have an immediate impact—including the food and beverage sector and companies working in heating, ventilation, and air conditioning (HVAC).

In a concept note outlining its goals, the group stated: ‘By aggregating demand, aligning on quality, and supporting high-integrity project pipelines a coalition of committed companies can accelerate deployment of proven solutions, send clearer signals to policymakers and markets, and create a more coherent narrative around super-pollutant mitigation.’

Central to Spectra’s approach is the creation of a financing mechanism that would expand corporate access to both mitigation technologies and the carbon credits issued for destroying super pollutants. The organisation also intends to help businesses integrate super-pollutant strategies into their wider sustainability plans, framing them as a valuable complement to existing emissions-reduction efforts.

The proposal introduces a membership-fee structure that grants participating companies access to two dedicated forums: a general forum exclusively for credit buyers and a transaction-focused forum designed for organisations interested in directing capital toward project development through carbon credit purchases.

Spectra’s ongoing consultation will shape how project suppliers and intermediaries are involved. Their role, the organisers noted, will depend on feedback as the alliance finalises its governance model and operational design.
