Validators and verifiers

Validators and verifiers approved by the Federal Office for the Environment (FOEN) conduct an independent appraisal of projects and programmes and the emission reductions resulting from them.

Projects and programmes to reduce emissions must be validated by a validator approved by the FOEN at the applicant's own expense (Art. 6 para. 1 CO2 Ordinance). Project monitoring reports must be verified by a verifier approved by the FOEN (Art. 9 para. 2 CO2 Ordinance).

Feedback process for validators and verifiers

The FOEN assures the quality of validation and verification reports by the following process:

Feedback to validators and verifiers (PDF, 273 kB, 20.12.2023)Art. 6 para. 1 and Art. 9 para. 2 CO2 Ordinance

The communication UV-2001 (see link above) contains a detailed description of the feedback process.

The secretariat gives the validator or verifier feedback on each report, classifying it into one of the following categories: very good, good, unsatisfactory, or no comment.

This document sets out to indicate to the validators and verifiers which findings in the reports automatically and in isolation lead to an overall unsatisfatctory classification, i.e. even in the absence of further findings. In this way, the Administrative Office for Compensation is supporting the validators and verifiers in setting priorities in the respective reports.
