Greenhouse Gas Verification

What does a GHG verification consist of?

A greenhouse gas verification consists of evaluating an emissions inventory or report to ensure the accuracy of the information it contains and to confirm its compliance with applicable requirements, according to the criteria of the reporting program. The process can be divided into five main steps, each corresponding to specific verification activities:

The following documents that support our credentials are in Spanish, as it is the official language in which they were emitted. Please contact us for the corresponding translations.

1.- Engagement Terms
The criteria, objective, materiality, and scope for the verification are established.
2.- Development of the Verification Procedure
The verification team is assigned and the GHG information is requested to generate the verification plan.
3.- Evaluation of Information and Data Systems
The evaluation covers the traceability and management of information associated with the GHG declaration.
4.- Evaluation According to the Verification Criteria
The GHG declaration is reviewed according to the agreed criteria and program.
5.- Independent Review
Qualified personnel not involved in the project evaluate relevant inputs to confirm the adequacy of the verification. Based on this evaluation, they decide on the verification opinion to be issued.
6.- Issuance of the Verification Opinion
The resolution document is issued following the verification of the clients’ declaration.

At Consultora 27, we are accredited by the Mexican Accreditation Entity (EMA) and approved by the Federal Environmental Protection Agency (PROFEPA) as a Certification Body to Verify the Emission of Greenhouse Gases under ISO 17029:2019 / ISO 14065:2020.

GHG Programs

GHG programs are greenhouse gas emissions reporting criteria, under which inventories are carried out that are subsequently verified by a certified body.
National Emissions Registry (RENE)

Report GHG emissions to SEMARNAT through Section VI of the Annual Operation Certificate (known in Mexico as the COA). It is mandatory for establishments in Mexico that emit more than 25,000 tCO2 e per year.

Emissions Trading System (SCE)

Report CO2 emissions from stationary sources to SEMARNAT through Section VI of the Annual Operation Certificate (known in Mexico as the COA). It is mandatory for establishments in Mexico that emit more than 100,000 tCO2 e per year.

GHG Protocol

Voluntary program of international recognition that includes standards and guidelines for reporting greenhouse gas emissions from multiple sectors and types of organizations.

ISO 14064-3:2019

Standard by the International Organization for Standardization (ISO) that establishes guidelines for verification of greenhouse gases. Many GHG programs use this standard as a basis to establish their criteria.
