✪ Member briefing: Bio-CO₂: unlocking a strategic market for decarbonisation
As governments and industries accelerate efforts to meet net-zero targets, attention is increasingly turning to solutions that go beyond emissions reduction towards carbon removal and circular carbon use. In this context, bio-CO₂ is emerging as an important new opportunity for the biogas and biomethane sector, with growing relevance for industrial decarbonisation, low-carbon fuels and negative emissions.
Unlike fossil CO₂, which releases carbon stored underground for millions of years, bio-CO₂ is derived from biological processes such as anaerobic digestion (AD), fermentation and other biomass-based conversion pathways. As demand rises for sustainable, non-fossil sources of CO₂, bio-CO₂ is gaining strategic value across a range of established and emerging markets, including food and beverage, greenhouses, chemicals, e-fuels, building materials and carbon capture and storage.
At the same time, policy and market frameworks are beginning to evolve in support of carbon removals, sustainable CO₂ sourcing and industrial defossilisation. However, barriers remain around infrastructure, certification, price visibility and investment certainty, which continue to constrain the development of a more mature bio-CO₂ market.
The WBA policy analysis considers what bio-CO₂ is, where it comes from, what can be done with it, and the policy and investment conditions required to unlock its full value for the biogas and biomethane sector.
