What is the Certificate?

The Biomethane Guarantee of Origin Certificate proves that a specific volume of gas was produced from a 100% renewable source, allowing companies across different sectors to neutralize their emissions even without consuming physical biomethane, advancing their decarbonization journeys.

Why obtain the certificate?

1

Traceable and auditable

2

Accepted in emissions inventories under the GHG Protocol

3

Official instrument for compliance with the Fuel of the Future Law for the fossil natural gas sector

4

Blockchain registration to prevent double counting

5

Enables verification of emissions reduction or neutralize even without physical biomethane consumption

6

Strategic decarbonization tool for companies that cannot yet fully switch to renewable fuel

Understand the Fuel of the Future's Law

In effect since October 2024, this law promotes the energy transition and decarbonization of the fossil natural gas sector, and establishes that the Biomethane Guarantee of Origin Certificate (CGOB) can be used to prove the decarbonization of any fossil fuel.

The initial target is 1% biomethane acquisition by natural gas producers and importers in 2026, growing to 10% in subsequent years.

But the law’s impact goes beyond regulation: it also recognizes other guarantees of origin certificates, strengthening the voluntary carbon market.

In practice, this means that companies across various sectors can accelerate their decarbonization journey through these certificates—even before implementing their own energy replacement projects. Using these internationally recognized certificates ensures traceability, transparency, and security in proving avoided emissions.

FAQ

What is CGOB?

The Biomethane Guarantee of Origin Certificate (CGOB) proves that a specific volume of gas was produced from a renewable source (biogas) and injected into the grid or physically delivered. In addition to being a traceable document, it is registered on blockchain, which prevents double counting of emissions.

What is the purpose of CGOB?

It allows companies across different sectors to reduce or offset emissions, with or without physical delivery of biomethane, thanks to the traceability of the production chain. For fossil natural gas producers and importers, it serves to demonstrate compliance with the regulatory targets of the Fuel of the Future Law.

What is the difference between CBIO, Carbon Credit, and CGOB?

  • CBIO: Regulatory certificate for liquid fossil fuel distributors. It encourages biofuel production but cannot be used to reduce emissions for the purchaser.
  • Carbon Credit: Environmental asset generated from various projects, used by companies that cannot fully eliminate their emissions. Credits are adopted for residual compensation.
  • CGOB: Official certificate that reduces or offsets emissions by replacing fossil fuels with renewable ones.

Is CGOB accepted by the GHG Protocol?

Yes. Provided traceability criteria and the Fuel of the Future Law requirements are met, audits can approve its use in emissions inventories.

Can CGOB be used to offset emissions?

Not in the traditional sense. CGOB is not a carbon credit. It promotes emissions reduction or neutralization by virtually replacing fossil fuel with renewable fuel. In other words, it is not compensation (offset), but substitution.

How to use CGOB in a sustainability strategy?

  • Neutralize emissions when physical biomethane is not available
  • Meet renewable energy targets
  • Declare low-carbon products and services
  • Fulfill client and supply chain requirements

How does Gás Verde sell CGOB without the physical molecule?

Biomethane is sold to fuel stations without the certificate. CGOB can therefore be sold separately, without risk of double counting, for companies wishing to neutralize emissions.

What is the difference between neutralizing, reducing, and offsetting emissions?

  • Neutralizing: Reducing emissions elsewhere to achieve a net zero balance.
  • Reducing: Cutting emissions directly in operations.
  • Offsetting: Maintaining emissions and purchasing third-party carbon credits.
