Renewable Energy Certificates provide the market-based evidence used by electricity buyers to substantiate renewable-power procurement and associated Scope 2 claims. Market expansion reflects the convergence of more formal corporate decarbonization programs, recurring compliance obligations, rising electricity demand from digital infrastructure, and a growing premium placed on certificates with stronger traceability, location, and new-build attributes.
GMI Analyst View
Based on discussions with industry experts, the global Renewable Energy Certificate (REC) market generated revenue of approximately USD 17.50 billion in 2022. We view that historic revenue base as evidence that certificate procurement had already progressed beyond a niche sustainability activity, creating a commercial foundation for the subsequent expansion of corporate contracts, registry participation, and compliance-led demand.
Renewable Energy Certificate (REC) Market Trends, Growth Drivers & GMI Forecast Outlook
Renewable generation expansion is enlarging the certificate supply base, while corporate climate commitments are making procurement more durable and structured. At the same time, oversupply in mature certificate systems and stricter rules for credible renewable claims are separating lower-value commodity instruments from traceable, project-linked supply.
Key Drivers
*Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.*
The build-out of renewable generation broadens the physical basis for certificate issuance, but its commercial effect depends on where new assets enter registry systems and whether their output meets buyers' quality requirements. Wind and solar additions can deepen liquidity in established programs while enabling newer certificate markets to attract multinational purchasers seeking locally sourced instruments.
Validated climate targets influence procurement differently from broad sustainability statements because they embed renewable-electricity decisions into reporting cycles, supplier engagement, and longer-term energy planning. As corporate buyers move from spot purchases toward structured procurement, certificate demand becomes more relevant to project developers, retailers, registry operators, and financing counterparties.
Hourly and location-sensitive matching is reshaping what buyers regard as a credible renewable electricity claim. This transition favors certificates associated with identifiable, recently developed assets and reliable time-stamped generation, while reducing the strategic appeal of undifferentiated legacy supply. It also increases the value of registry interoperability, data management, and verification infrastructure.
Key Restraints
*Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.*
European Guarantees of Origin illustrate the central tension in certificate markets: greater renewable output can expand available supply faster than cancellation demand. When certificates lose pricing power, renewable generators may still issue them, but their contribution to project economics weakens, particularly for developers that rely on certificate revenue alongside power sales.
Voluntary demand also remains exposed to governance changes inside corporate climate programs. Suspended, revised, or delayed commitments can affect procurement timing even where companies retain their broader decarbonization ambitions. For sellers, this raises the importance of diversified buyer portfolios and contracts that distinguish firm demand from nonbinding sustainability intentions.
Tighter additionality and deliverability rules should improve the integrity of renewable electricity claims, but they also make procurement more complex. Buyers with established energy-management capabilities can adapt through better contracting and data systems; smaller organizations may face higher qualification costs and reduced access to low-cost certificate supply.
GMI Analyst View
We see the forecast outlook as a quality-led expansion rather than a uniform rise across all certificate categories. Demand should increasingly favor supply that is recent, traceable, and geographically relevant, while commodity certificates from legacy assets face a more challenging pricing environment even where overall renewable procurement continues to grow.
Renewable Energy Certificate (REC) Market Segment Analysis
By Type
The Renewable Energy Certificate (REC) market voluntary segment generated USD 12.42 billion in 2025 and is expected to account for a 57.0% share by 2035. Voluntary demand is anchored in corporate renewable-electricity claims, supply-chain decarbonization commitments, and buyer preferences for specific project attributes. Its strategic importance rises as purchasers seek certificates that can withstand more exacting scrutiny around source, vintage, location, and additionality.
The compliance segment represented a 46.0% share in 2025 and is projected to generate USD 25.97 billion by 2035. Compliance demand is structurally supported by renewable portfolio standards, renewable obligation programs, and analogous statutory mechanisms. This mandated base provides recurring transaction activity and registry participation, particularly in jurisdictions where voluntary corporate purchasing remains less mature.
By Source
Wind generated USD 8.28 billion in 2025 and is projected to account for a 30.0% share by 2035. Wind remains an important source of certificate supply because utility-scale projects are deeply integrated into established registry and offtake structures. Its relative mix position is moderated by the faster expansion of solar capacity and the growing preference for certificates tied to newer projects in high-demand locations.
Solar is projected to generate USD 25.97 billion by 2035 and is expected to expand at a 12.5% CAGR (2026–2035). Solar-backed certificates benefit from widespread deployment, corporate familiarity with solar power-purchase structures, and strong alignment with new-build procurement strategies. The source is particularly well positioned where buyers seek geographically identifiable supply connected to their own operations or supplier networks.
Hydropower represented a 15.0% share in 2025 and is expected to account for an 11.0% share by 2035. Hydropower provides a large installed base of low-carbon certificate supply, especially in markets with longstanding generation fleets. However, its role in premium voluntary procurement is constrained where buyers prioritize newer assets or seek a clearer additionality link between certificate retirement and renewable investment.
Bioenergy generated USD 2.07 billion in 2025 and is expected to grow at a 9.5% CAGR (2026–2035). Bioenergy certificates serve specialized demand where industrial buyers value renewable-energy attributes associated with process heat, waste streams, or integrated energy systems. Growth is shaped by the ability of project owners to meet evolving feedstock sustainability, traceability, and regulatory eligibility requirements.
By Capacity
The <5 MW segment generated USD 3.91 billion in 2025 and is projected to account for a 14.0% share by 2035. Distributed facilities are relevant in certificate markets where rooftop solar, community projects, and small generators support local renewable procurement. Their participation expands the issuer base and can improve access to geographically proximate supply, although administrative and verification requirements can limit transaction efficiency.
The >5–15 MW segment represented a 28.0% share in 2025 and is expected to grow at a 14.0% CAGR (2026–2035). This tier is well aligned with corporate buyers seeking projects that are substantial enough for structured procurement but still close to local loads and commercial communities. Its growth reflects demand for identifiable, additionality-oriented supply that does not necessarily require the scale or complexity of the largest utility projects.
The >15–30 MW segment is projected to generate USD 15.10 billion by 2035 and represented a 25.0% share in 2025. Projects in this range occupy a useful position between institutional procurement needs and regional market accessibility. They can support utility and commercial-buyer demand while retaining the flexibility to participate in localized certificate systems and tailored offtake arrangements.
The >30 MW segment generated USD 6.90 billion in 2025 and is expected to account for a 27.0% share by 2035. Large facilities continue to supply substantial certificate volumes through standardized metering, established registry access, and long-term contractual structures. Their competitive position increasingly depends on whether scale is complemented by buyer-valued attributes such as new-build status, transparent provenance, and suitable delivery geography.
GMI Analyst View
We believe segmentation is increasingly determined by certificate credibility rather than generation technology alone. Buyers are differentiating among assets based on origin, timing, scale, and proximity to consumption, creating a stronger commercial divide between readily available legacy supply and certificates that can support more demanding renewable-electricity claims.
