What is Carbon Verification?

With the growing emphasis on sustainability and reducing carbon footprint, many organizations are voluntarily reporting their GHG emissions and claiming carbon offsets. However, for the reported emissions and offset claims to be credible, they need to be verified by independent third parties. This independent validation or assurance of the reported emissions and offset projects is known as carbon.

Developing an Emissions Inventory

The first step in the carbon verification process is for an organization to develop an emissions inventory that accounts for all sources of greenhouse gas emissions within their defined organizational and operational boundary. This includes direct emissions from owned/controlled sources as well as indirect emissions from imported electricity, heat, and steam. The inventory development process involves - collecting activity data, selecting appropriate emission factors, calculating emissions using relevant methodology/protocol, and documenting the quantification process.

Appointing an Accredited Verification Body

Once the emissions inventory is completed, the reporting organization appoints an accredited verification body to conduct an independent third-party verification of their GHG emissions report. Carbon Verification bodies are accredited and certified by recognition programs like Clean Development Mechanism (CDM), Verified Carbon Standard (VCS) to ensure they have the required technical expertise and quality assurance systems to perform verification work.

Conducting a Detailed Verification Audit

The appointed verification body will then conduct a thorough verification audit of the reported emissions. This involves - reviewing the emissions inventory and underlying activity data, means of gathering data, calculations performed, emission factors used and references/standards followed. The verifiers also assess the management and reporting systems in place and perform site visits for sampling checks on quality of data, record maintenance and reporting protocols.

Identifying Non-conformities and Making Corrections

During the audit, the verification team reviews the inventory for any non-conformities with the selected quantification methodology and reporting protocol. Issues like incomplete activity records, inconsistent calculation approaches, unreasonable assumptions, erroneous emission factors etc are flagged. The reporting entity has to address any mistakes identified and make necessary corrections/adjustments in the inventory before it can be verified.

Issuing a Verification Report and Opinion

Upon satisfactory resolution of non-conformities, the verification body prepares and issues a detailed verification report. This outlines the verification process followed, any adjustments made to the inventory during verification, verification criteria used and the overall verification opinion. The verification opinion clearly states if the reported emissions inventory/offset project performance is materially correct and suitable for the intended application or not.

Verification Outcomes and Assurance Levels

The verification opinion can be either- a) a positive verification opinion where reported data is materially correct; b) a qualified positive where minor errors/deviations can be corrected; or c) an adverse opinion if inventory/claims cannot be materially verified. Besides, some standards also provide different levels of assurance offered like reasonable, limited or reasonable-limited based on the rigor of verification approach.

Benefits of Third-party Carbon

Independent verification provides several important benefits. It ensures credibility and integrity of publicly reported emissions information. It boosts stakeholder confidence in reported data that underpins offset transactions or programs like emission trading schemes. Verification helps identify scope for improvement in emissions accounting. Regular verification reinforces transparency and accountability in climate action initiatives. It helps protect the environmental and financial value of offset credits and drives continual performance improvement.

Maintaining Verification Records

The verified entity is responsible for maintaining verification records like verification reports, audit evidence, correspondence with verifiers as documentary proof. This helps in any subsequent verification or if regulators want to validate the credibility of reported information. Proper records also facilitate tracking performance trends over time and preparing for future verification cycles on an annual or multi-year basis.

Carbon verification plays a vital gatekeeping role in ensuring rigorous, transparent and standardized GHG accounting across mitigation activities. It helps drive higher accuracy and consistency in emissions reporting. Independent verification is fast emerging as an essential requirement to build integrity in carbon markets and boost the climate credibility of companies and projects reducing emissions.
