OCP Reaches 50 Active Methodologies

Today, we're proud to mark a significant milestone in the voluntary carbon market: OCP has published its 50th active methodology. This isn't just a number — it's a reflection of years of collaborative work, rigorous science, and a shared commitment to making high-integrity carbon credits accessible at scale.

Why Methodology Breadth Matters

Methodologies are the backbone of the voluntary carbon market. They define how emissions reductions and removals are measured, reported, and verified — and without them, no project can generate a credible carbon credit. For too long, the market has been constrained by a narrow set of approved frameworks, leaving vast categories of climate action without a viable pathway to financing.

Breadth matters because the climate crisis demands solutions across every sector of the economy. A market that can only credit a handful of project types will always fall short of what's needed. Reaching 50 active methodologies means that more project developers, in more geographies, working on more types of climate solutions, now have a credible path forward.

Sectors Now Covered

OCP's methodology library now spans a wide and growing range of sectors, including:

• Methane capture — from landfills, coal mines, and agricultural waste streams
• Soil carbon — sequestration through improved land management and cover cropping
• Reforestation and afforestation — restoring forests and establishing new tree cover on degraded land
• Improved cookstoves — reducing emissions from household biomass combustion in developing regions
• Marine and coastal ecosystems — blue carbon projects protecting mangroves, seagrasses, and salt marshes
• Industrial process emissions — abatement in cement, steel, and chemical manufacturing
• Agricultural soils — nitrous oxide reduction through precision fertilizer management
• Refrigerant destruction — eliminating high-global-warming-potential gases from end-of-life equipment

This diversity reflects the reality of climate action: there is no single solution, and the market must be equipped to reward progress wherever it happens.

Faster Approvals, Without Compromising Rigor

One of the most meaningful aspects of this milestone is how we got here. OCP's collaborative, expert-driven methodology development process has consistently delivered approval timelines of 3 to 6 months — compared to the multi-year cycles that have historically characterized traditional registries.

This speed is not the result of cutting corners. It comes from a process built around open participation, transparent public comment periods, and standing expert panels who engage continuously rather than episodically. When the right people are in the room from the start — scientists, project developers, verifiers, and buyers — the path to a sound methodology is shorter and more direct.

For the market, faster approvals mean that emerging climate solutions don't have to wait years before they can access carbon finance. That matters enormously for the pace of deployment.

What This Means for Project Developers

For project developers, 50 active methodologies represents a fundamentally different landscape than existed just a few years ago. Where developers once faced the choice of squeezing their project into an ill-fitting framework or embarking on a costly, uncertain methodology development process of their own, they now have a rich library of options to draw from.

More frameworks mean:

• Greater flexibility to structure projects that reflect real-world conditions
• Reduced development costs, as existing methodologies can be applied rather than created from scratch
• Faster time to market, enabling projects to begin generating credits sooner
• Stronger buyer confidence, because credits issued under well-established, openly developed methodologies carry greater credibility

This is the kind of infrastructure that allows the voluntary carbon market to scale responsibly — not by lowering the bar, but by making it easier to clear it.

Looking Ahead

Reaching 50 is a moment worth celebrating. But it's also a starting point. Over the next 12 months, OCP is targeting the publication of an additional 20 methodologies, with a particular focus on underserved sectors and geographies where the need for carbon finance is greatest and the existing frameworks are thinnest.

We'll continue to prioritize transparency, scientific rigor, and genuine collaboration with the communities and experts who make this work possible. The voluntary carbon market has an essential role to play in the global response to climate change — and a robust, credible methodology library is one of the most important things we can build to help it fulfill that role.

Thank you to the scientists, developers, verifiers, and partners who have contributed to every one of these 50 methodologies. This milestone belongs to all of you.
