RTFO compliance is entering a decisive phase. By 2026, obligation levels exceed 16%, with the development fuel target nearing 2%. This is no longer incremental tightening; it is a structural shift in the UK transport fuel market.
Annual RTFC demand in 2026 is expected to exceed 7 billion certificates, while supply growth remains concentrated in a narrow set of high-efficiency pathways. Nearly 90% of RTFCs already come from double-counting fuels, and dependence on these pathways is increasing. Scarcity is being priced in.
The Strategic Role of Biomethane
Biomethane sits at the centre of this equation. When produced from approved waste and residue feedstocks, it delivers double-counting RTFCs, strong lifecycle emissions performance, and clean auditability. As targets rise, biomethane is no longer supplementary—it is becoming core.
The Constraint: Access
UK biomethane supply remains limited, while competition among obligated parties intensifies. Higher targets mean thinner buffers and sustained pressure on RTFC prices—anchored by the buy-out, but driven by availability. In 2026, waiting is a financial exposure.
The CEE Advantage
Central and Eastern Europe changes the equation. CEE biomethane production is scaling rapidly into 2026. Hungary and neighbouring markets are upgrading biogas assets, commissioning new biomethane capacity, and expanding waste-based feedstock utilisation.
Several UK-approved double-counting biomass categories, including agricultural residues and food-industry by-products, are available at scale. These are certified, RTFO-eligible volumes—available now.
Market Positioning
Forward-looking obligated parties are already securing CEE-sourced biomethane to stabilise compliance costs and hedge RTFC volatility. Those who delay will compete for marginal volumes in a tightening market.
Partnering with DeCarbon
DeCarbon is an established and active participant in the Central and Eastern European biomethane market, working with a broad network of certified producers and counterparties across the European Union. Through these partnerships, DeCarbon is well positioned to support UK obligated parties with reliable, RTFO-eligible biomethane volumes.
