Verifiers are external, independent bodies that are accredited (UKAS in the UK) to verify annual emissions reports. The verification process is subject to strict external and internal procedures. The verification process normally begins from September through to the final reporting of an operators annual emissions which is submitted through the regulators on line reporting system.
Verifiers will undertake site visits to inspect equipment and meters and, to ensure that the greenhouse gas permit is reflective of the installation. The verifier also checks that Operators are aware of their reporting obligations and audits emissions and activity level calculations.
Verifiers may also request physical copies of fuel logs etc. to check against the calculations and may question anyone involved in the data flow process.
Once verified, the operator then issues the operator with a verification opinion using the regulators on line system. If annual emissions reports can not be verified, the operator may incur civil penalties issued by the regulator.
