The European Union’s Renewable Energy Directive III (RED III), formally published in November 2023 (Directive 2023/2413), marks a significant legislative advancement in accelerating Europe’s transition to a low-carbon energy system. Building on its predecessor, RED II, this updated directive reinforces the EU’s climate objectives and introduces stricter obligations for renewable energy producers, particularly those operating within the fast-growing biomethane sector.

The directive’s overarching ambition is to raise the share of renewable energy to at least 42.5% of gross final consumption by 2030, with an additional indicative target of 2.5% to reach a total of 45%. Member States must transpose RED III into national law by May 2025, making the current period pivotal for biomethane market participants to prepare for the new regulatory landscape. This deadline also brings a short-term phase of regulatory uncertainty and potential divergence, as national transpositions may differ, creating a patchwork of country-specific rules and incentive schemes that businesses must closely track.

Core Requirements of RED III for Biomethane

RED III introduces a range of specific and more demanding requirements for the biomethane sector, which are set to reshape production practices, certification protocols, and commercial strategies.

1. Stricter Sustainability Criteria for Feedstocks
   The directive tightens rules regarding eligible feedstocks, phasing out the use of food and feed crops, and placing greater emphasis on RED-compliant materials such as municipal waste and agricultural residues. This not only serves as a regulatory compliance issue but also signals a market shift, encouraging producers to optimise their value chains through sustainable sourcing and innovation in production techniques. It incentivises a move towards non-food-competing inputs and promotes the use of advanced anaerobic digestion and carbon capture technologies.
2. Tougher Greenhouse Gas Emissions Thresholds
   RED III mandates a further reduction in lifecycle GHG emissions, compelling producers to lower their carbon footprints. This may necessitate investments in efficiency improvements, emissions mitigation infrastructure, and advanced processing technologies to meet the more rigorous standards.
3. Enhanced Traceability and Certification Standards
   Producers are now required to provide stronger evidence of compliance, with stricter traceability mechanisms to verify sustainability claims. This is critical to safeguarding the credibility of the market and preventing fraud. Voluntary schemes such as ISCC, SURE, and REDcert are aligning their certification criteria to reflect these upgraded standards.

Compliance with RED III will be a precondition for access to public financial support, including subsidies and feed-in tariffs, in several EU Member States. This means adherence is not merely bureaucratic but directly tied to financial viability, especially as biomethane production costs remain higher than those of natural gas. Companies procuring biomethane must also ensure their suppliers are RED III-compliant to maintain the environmental integrity of their supply chains. Failure to comply could result in financial penalties or loss of essential support mechanisms.

Strengthening the Union Database (UDB)

RED III also strengthens the Union Database (UDB), which aims to centralise the registration of all biofuels, bioliquids, and biomethane intended to meet EU sustainability targets. All volumes of biomethane injected into the EU’s interconnected gas grid and claimed as sustainable must be logged in the UDB. This central platform provides traceability, prevents double counting, and supports cross-border market transparency, establishing a single source of truth regarding the renewable origin of biomethane.

Impacts and Challenges for Biomethane Producers and Users

The implementation of RED III will have wide-ranging implications for producers and users of biomethane across Europe.

• Upgraded Emissions Performance: Operators must demonstrate improved GHG performance, requiring technical upgrades such as high-efficiency digesters or carbon capture units.
• Feedstock Pressure and Supply Chain Risks: Heightened sustainability criteria will intensify demand for RED-compliant feedstocks. This will require robust procurement strategies, new partnerships with farmers and industry players, and long-term supply contracts. Feedstock variability and competition from other bioenergy sectors further complicate the picture.
• Permitting and Grid Access Challenges: Delays in permitting procedures and lack of clear frameworks for grid connection requests continue to hamper project deployment. Non-standardised processes for selecting EPC (Engineering, Procurement, and Construction) contractors can also create bottlenecks and cost inflation.
• Fragmented National Approaches: Variations in how Member States manage Guarantees of Origin (GOs) and biomethane trading rules present major obstacles to a harmonised European market. For instance, the procedures for cancelling GOs differ by country. This makes a uniform procurement approach impractical, businesses must instead develop localised compliance and sourcing strategies.

Proactive Strategies for Compliance and Competitive Advantage

To remain compliant with RED III and unlock emerging opportunities, businesses should take the following actions:

1. Monitor Legislative Developments
   Closely track EU and Member State-level updates to RED III transpositions. Timely awareness of changes allows businesses to adapt their compliance strategies in advance of the May 2025 deadline.
2. Engage with Certified Verification Bodies
   Work with certification organisations such as ISCC, SURE, or REDcert to ensure compliance. Accredited verification is key to maintaining market access and unlocking financial support.
3. Enhance Environmental Performance
   Invest in efficiency improvements, advanced digestion technologies, and feedstock optimisation to stay ahead of GHG reduction targets. Explore technologies such as carbon capture and storage (CCS) to future-proof operations.
4. Secure Sustainable Feedstock Supply
   Establish reliable feedstock sources through long-term agreements and strategic partnerships with agricultural and industrial waste producers. This helps mitigate supply volatility and ensures consistent production.
5. Navigate Guarantee of Origin (GO) Systems and the UDB
   Understand the distinctions between national GO registries (e.g., ERGaR, AIB) and prepare for full integration into the Union Database. This is vital for enabling cross-border trade and ensuring regulatory recognition.
6. Incorporate Financial Planning
   Factor in the higher upfront capital and operational costs associated with biomethane and ensure alignment with available subsidy schemes and carbon pricing incentives. Early investment can secure a favourable market position and ensure regulatory preparedness.
