    Not sure if you’re ready for verification?

    If your organization already measures or reports its Greenhouse Gas (GHG) emissions, independent verification can provide greater confidence in that information.

    At Control Union, we review GHG inventories, statements and projects under international standards, assessing the information, data and methodology used.

    Complete our self-assessment!

    It includes a few questions about your inventory, scope, available information and verification objective. It can help you identify what information you already have prepared before making your first enquiry.

    What can verification provide?

    • Greater confidence

      Provides an independent assessment of the reported information.

    • Greater assurance for communications

      Allows reviewed information to be presented to customers, stakeholders, headquarters or other recipients.

    • Preparation for new requirements

      Can help respond to supply chains, reporting frameworks or commitments that require independently supported climate information.

    What is a carbon footprint?

    A carbon footprint quantifies the Greenhouse Gas (GHG) emissions associated with an organization, activity, project or product. Different gases are usually expressed in tonnes of carbon dioxide equivalent (tCO₂e), allowing them to be combined under a common unit.

    Understanding these emissions helps identify where an organization’s climate impact is generated and provides information to set priorities, manage reductions and report results.

    Within an organization, emissions are usually analysed by considering different sources:

    Scope 1
    direct emissions from sources owned or controlled by the organization.
    Scope 2
    indirect emissions associated with purchased and consumed energy.
    Scope 3
    other indirect emissions occurring throughout the value chain, both upstream and downstream.

    Why do companies measure and report GHG emissions?

    Emissions information is being used for an increasing number of purposes.

    Measurement and verification are different activities. The company (or whoever develops its inventory) quantifies and prepares the information. Control Union acts as an independent third party to assess it.

    Today, companies may need information about their emissions for a variety of reasons:

    • Sustainability and ESG reporting;

    • Requests from customers or headquarters;

    • Climate commitments and targets;

    • Internal management and emissions monitoring;

    • Participation in supply chains.

    A practical introduction to understanding:

    • what a GHG inventory is;
    • how emissions are organized;
    • the difference between verification and validation;

    What does Control Union do?

    Control Union provides independent validation and verification services for GHG information.

    Our work consists of reviewing a GHG statement against defined criteria, assessing the methodology used, data, calculations, boundaries, information sources, controls and evidence relevant to the agreed scope.

    • Verification is used for information and results that have already been obtained.
    • Validation applies to statements related to future or projected results, assessing the assumptions and methodologies that support them.

    The objective is to provide an objective and independent assessment of the information presented.

    Why choose Control Union?

    Control Union Argentina is accredited by ANAB as a Greenhouse Gas validation and verification body under ISO 17029, ISO 14065 and ISO 14064-3.

    This means that our processes, technical team and management system have been independently assessed for the provision of GHG validation and verification services.

    What do we offer?

    • International accreditation for our GHG services.
    • Specialized technical team in validation and verification.
    • Local presence, backed by Control Union’s international network.
    • Independent assessment of reported information.

    Frequently asked questions

    The service presented on this page focuses on the independent validation and verification of GHG information. The organization (or the team it has engaged to perform the calculation) prepares the inventory or statement. Control Union then assesses that information as an independent third party.

    Measuring involves identifying emission sources, collecting data and quantifying emissions. Verification involves an independent third party subsequently assessing the statement, data and evidence against established criteria.

    Verification applies to information related to events or results that have already occurred. Validation is used to assess statements related to future or projected results and the reasonableness of the assumptions supporting them.

    It depends on the objective of the inventory, the applicable criteria and the defined scope. During the initial enquiry, we can review what information forms part of the statement you are seeking to verify.

    This will depend on each organization and scope. The process usually starts with the GHG inventory or report and the information needed to support the boundaries, emission sources, activity data, emission factors, calculations and controls used.

    The timeframe depends on the scope, the complexity of the organization, the number of sites, the emissions included, the availability and quality of the information, and the process for resolving any findings. Once we have this information, we can prepare a proposal suited to your specific case.

    The quotation depends on the scope and characteristics of each verification. To prepare a proposal, we need some basic information about the organization and the GHG statement.

    The outcome and documentation issued depend on the service, scope and agreed criteria. This is defined at the beginning of the process and set out in the corresponding proposal.

    Yes. Share the scope, period, standard used and background information from the previous verification so our team can review the next cycle and prepare a proposal.
