Happy Earth Day and happy birthday to us! Fun fact: GMA was incorporated on April 22, 2024, so we get to celebrate both. Not a bad alignment.

We’re so grateful to be doing this work, and our impact continues to grow. Now entering year three as an organization, we’re turning up the dial on implementation with major procurement milestones, new RFPs, fresh book and claim frameworks, and the eagerly awaited release of the AIM Platform’s Standard and Guidance to help unlock the next wave of decarbonization investment. Dive in below for the latest, and if you’re already thinking ahead to New York Climate Week, we’re gearing up for the third annual Green Markets Day on Tuesday, September 22nd — more to come soon.

Watch our latest explainer video, in which GMA’s Joan Gibbons explains why companies often can’t access low-carbon cement and concrete in their region and how book and claim can serve as an unlock and market accelerator.

Program Updates

Aviation

The Sustainable Aviation Buyers Alliance (SABA) has made significant advancements through both procurement and market infrastructure milestones. Infinium’s Project Atlas was selected as the winner of SABA’s next-generation SAF procurement, following a comprehensive, multi-stage review and due diligence process conducted on behalf of SABA’s corporate buyers. In parallel, the SAFc Registry surpassed 500,000 metric tons of CO₂e abated, reinforcing the strength of corporate demand for credible, scalable SAF solutions.

Trucking

The GMA Trucking team’s recently released whitepaper shares detailed findings from its pilot RFP, introduces the challenges GMA Trucking seeks to address, and explores the critical role of demand aggregation and book and claim. GMA Trucking also hosted a webinar on January 15th with speakers from the winning carrier, Nevoya, and corporate buyers Amazon and Etsy. The Trucking team is currently exploring procurement models for its second RFP and planning to integrate physical demand with book and claim for the first time. Get in touch if that sounds as exciting to you as it does to us!

Cement & Concrete

GMA’s cement and concrete program, run in partnership with RMI, finalized a sector-specific Book and Claim Framework in January, following extensive engagement across the value chain. The framework underpins SCoBA’s first RFP, launched in early April and targeting up to 85,000 tCO₂e per year of low emissions cement attributes. We encourage eligible cement producers to submit proposals via the GMA website through June 19, and look forward to seeing this process progress over the coming months.

Fertilizer

GMA Agriculture’s low-emission fertilizer program wrapped up its supplier outreach this spring, drawing responses from producers across a range of decarbonization technologies. The team is now meeting with buyers to define procurement criteria ahead of a formal RFP.

High-Value Chemicals

GMA Chemicals is advancing its pilot procurement for low-carbon ethylene (think plastics!) with an established buyer group and is set to launch its RFP in the coming days — paving the way for the first-ever book and claim offtakes for low-emission chemicals.

Maritime

Late last year, the Zero Emission Maritime Buyers Alliance (ZEMBA) announced that it will facilitate some of the first commercial e-fuel deployments in the maritime sector.

Members are supporting the deployment of both e-methanol and e-ammonia from 2027-2031. Contracting for these landmark deals is currently underway; freight buyers interested in lowering their Scope 3 maritime emissions should reach out through shipZEMBA.org to learn more!

The AIM Platform

The Advanced and Indirect Mitigation (AIM) Platform released V1 of its Standard and Guidance, providing companies with a clear, credible framework for investing in high-integrity emissions reductions across their value chains. The publication follows two pilot processes and public stakeholder consultation periods to ensure the Standard is actionable and applicable across sectors and technologies. A webinar marking the release took place April 21 – a recording is available here.
