The biomethane buyer’s guide to cost, supply, and certification

Biomethane is gaining momentum: 1,620 plants across 25 countries, with more than €28 billion in private investment committed ahead of 2030 (EBA, 2025).

From February 2027, the SBTi Corporate Net-Zero Standard v2.0 addresses biomethane certificates in a Scope 1 context for the first time, for targets set from 2028. Claims must result in reductions within your own physical inventory.

Feedstock categories, certification schemes, registries, and national regulations influence carbon intensity, pricing, and claim eligibility. The wrong contract leaves you with a claim you cannot defend at audit.

Europe’s biomethane market is expanding, but more supply does not make every procurement decision straightforward.

Our biomethane guide looks at the factors companies should understand before moving further, including:

  • how the European biomethane market is developing

  • what affects supply, pricing, and availability

  • how feedstock, origin, and certification can change the value of biomethane

  • where biomethane can support voluntary and compliance objectives

  • what to consider when assessing different procurement routes

ACT structures procurement across renewable energy, biomethane, renewable fuels, carbon, and compliance markets, so clients can meet regulatory and voluntary targets without building that expertise in-house. Since 2009, over 9,000 clients have used ACT to source, validate, and cancel environmental certificates across European and global markets.
