Companies certified in accordance with the ZNU Standard - driving sustainable change are audited annually by independent certification bodies and thereby credibly prove the steps they have initiated and completed and the targets they have set themselves.
To avoid and reduce greenhouse gas emissions companies have to systematically capture, document and analyse these. To this end at least all of the emissions governed by Scope 1 and 2 in the GHG Protocol are captured on the basis of international standards (GHG Protocol, ISO 14064). The goal is to have as much primary data as possible.
Possible proof here includes corporate and/or location climate footprint for example (e. g. GHG Protocol or ISO 14064), Critical Review, data on location-related greenhouse gas emissions from energy consumption (including transport fuel) and coolant losses (e.g. on the basis of ISO 50001, a product life cycle assessment, energy balance or product climate balance).
Furthermore, targets, measures and cooperations with climate protection stakeholders must exist, e.g. climate protection programme.
