Biogas / Biomethane Certificates
Decarbonise your Scope 1 by switching to renewable gas and go one step further in your net-zero journey.

The next step in energy decarbonisation
Reduce Scope 1 emissions
Lower the GHG output of sources owned or controlled by your organisation.
Save on EU ETS allowances
Reduce your obligations to buy carbon quotas according to European legislation.
Switch to renewables while keeping your gas supplier
Source renewable gas from national grids without the need for technical upgrades.
Advance towards climate targets
After electricity, gas is the natural place for companies to continue reducing emissions.
What is biogas, and how is it different from biomethane?
Biogas is a combination of methane, CO2, and other gases obtained from the controlled decomposition of organic matter. Once refined — or “upgraded” — it is turned into biomethane, a compound identical to natural fossil gas that runs through national grids, except it is virtually carbon-neutral.
Biomethane and biogas are often called “green gas,” a broader category that also includes other renewable fuels of non-biological origin, such as green hydrogen and syngas.
What is a biomethane certificate?
Biomethane certificates are documents that attest to the production, ownership, and consumption of biomethane, along with its sustainability attributes. Different countries and regions use different certification systems: in Europe, these include Guarantees of Origin (GOs) and Proofs of Sustainability (PoS), while in North America, Renewable Thermal Certificates (RTCs) are used.
Ecohz is cerfitifed by the International Sustainability and Carbon Certification (ISCC), which allows us to provide customers with ISCC EU-certified biomethane for voluntary and compliance purposes in Europe.
How can companies source biomethane certificates?
Biomethane certificates
GOs in Europe and RTCs in North America, sourced independently from physical gas to claim ownership or consumption of a corresponding volume in MWh.
ISCC Proof of Sustainability (POS)
Used to track and claim specific sustainability and GHG reduction attributes. Transferred between countries and owners to support carbon intensity claims, for example, under the EU Emissions Trading System (ETS) and in relation to renewable transport fuels.
Biomethane Purchase Agreements (BPA)
Long-term off-take contracts, including the delivery of physical gas and bundled biomethane certificates.
Sourcing biomethane in four simple steps
01 Strategy
Our advisors tailor a procurement plan for your company based on your location, volume of consumption, and reporting framework.
02 Offer
You receive an offer with a specific rate and expiry date. Upon acceptance, we secure the quoted price.
03 Contract
We deliver a standardised contract to guarantee the purchase and delivery of biomethane certificates by an agreed date.
04 Delivery
We provide you with an invoice and all the necessary documentation for renewable energy reporting.
Where is biomethane available?
Ecohz can provide biomethane certificates to cover gas consumption in almost every country in Europe and in the US.
The maps indicate the European countries and US states with functioning registries for the issuance and redemption of biomethane certificates. Many countries allow the redemption of certificates issued outside of their borders for domestic consumption.
Biomethane Purchase Agreements (BPAs)
Similar to Power Purchase Agreements (PPAs), Biomethane Purchase Agreements (BPAs) are long-term off-take contracts that ensure the availability of renewable gas in geographies with limited supply.
Ecohz provides personalised advisory services to help companies secure BPAs and claim all the sustainability benefits of consuming biomethane.
Ecolabels for additional impact
Source biomethane that fulfils stricter sustainability requirements and catalyses higher environmental and social benefits.
