Verification

To ensure that the third party verification activities undertaken by companies are broadly comparable, CDP requires verification to be completed in accordance with recognized verification standards. These standards must have a common set of attributes which are set out in the criteria below. Any third party verification standard referenced in a company’s submission to CDP will be assessed against these criteria to determine acceptability. Note that “Agreed upon procedures”, “pre-assurance” or internal verification is not accepted as verification under the CDP scoring methodology.

Given the diversity of geographies and industries amongst CDP responders, and the evolution of standards, it is not possible to provide an exhaustive list of all standards that meet these criteria. However, to support companies in their disclosure process, CDP has produced a list of standards that have been deemed suitable for CDP reporting and a list of standards that are not considered appropriate. A third list includes those that are currently under review – CDP will endeavour to confirm whether these standards meet the criteria as soon as possible.

The criteria for third party verification standards are:

• Relevance: The standard should specify that it relates to a 3rd party audit or verification process; for a program related standard, 3rd party verification should be specified as part of the program compliance.
• Competency: The standard should include a statement regarding competency of verifiers; where it is a program and verification parties are stipulated, competency is assumed to be determined by the 2nd party and therefore need not be explicit in the standard.
• Independence: The standard should contain a requirement that ensures that impartiality is maintained in cases where the same external organization compiles and verifies a responding company’s inventory.
• Terminology: The standard should specify the meaning of any terms used for the level of the finding (e.g. limited assurance; reasonable assurance).
• Methodology: The standard should describe a methodology for the verification that includes the verification of the process and/or system controls and the data.
• Availability: The standard should be available for scrutiny.

This guidance was updated in January 2013.

Note: Companies should attach the certification letter AND certificate. Verification of GHG emissions as part of CTS certification can be annual or biennial. If a company is in the process of having the current reporting year's emissions verified, they should report "third party verification or assurance underway - last year's statement attached" and attach documentation from the most recent year with verification but no earlier than two years prior to the current reporting year.

Companies should attach the Toitū carbonreduce certificate and assurance statement. Verification of GHG emissions as part of Toitū carbonreduce certification is annual. If a company is in the process of having the current reporting year's emissions verified, they should report "third party verification or assurance underway - last year's statement attached" and attach documentation from the previous year.

Tokyo Emissions Trading Scheme

Verification under the EU Emissions Trading Scheme (EU ETS) Directive and EU ETS related national implementation laws

¹ The assurance provider needs to be subject to Parts A and B of the Code of Ethics for Professional Accountants issued by the International Ethics Standards Board for Accountants (the IESBA Code), or professional requirements, or requirements in laws or regulations, that are at least as demanding and/or clearly demonstrates equivalent independence in the assurance statement.

² Only assurance engagements that state that they are in accordance with the regulations and NGER (audit) determination 2009. Verification engagements do not give an opinion and therefore will not meet our criteria for the statement. Submitting data under NGER does not automatically confer to achieving an appropriate level of verification unless the condition stipulated previously is met.

Non verification standards

(includes climate reporting/environmental management standards, verification services)

Australian Government's National Carbon Offset Standard
Note: This is not a verification standard. All verification undertaken for this program is done in accordance with another verification standard (such as ASAE3000 or ISO14064-3).

EPA Climate Leaders Review
Note: This applies to the “review” only. EPA does not regard the “review” as independent third party verification.

Statements from this process are not “reviews” and should be completed using a standard that meets CDP’s criteria to be accepted.
