Savings as a result of:

- reuse of products recovered in the purification process or from the newly manufactured products.

- reduction of expenditure on employment, electricity costs, etc.

- reduction the amount of ecological fees, service fees, etc.

Savings are not valid if the entity only meets the legal requirements (e.g. within their permits). Only the "surplus" of reduced pollutants or voluntary actions are the basis for determining the amount of saving.
