Disclosure focus

Disclosure 305-6 requires an organisation to report its production, imports and exports of ozone-depleting substances in metric tonnes of CFC-11 equivalent.

The disclosure covers three separate quantities: ODS production, imports and exports. Production is calculated as the amount of ODS produced minus the amount destroyed using technologies approved by the Parties to the Montreal Protocol and minus the amount entirely used as feedstock in the manufacture of other chemicals. ODS that are recycled or reused are excluded from the calculation. The organisation must also identify the substances included, the source of the factors used and the standards, methodologies, assumptions and calculation tools applied.

This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official Global Reporting Initiative source.
