How can I find now the kg CO2/kg Chemical?
The PCR are defined, but how can the tannery find the numbers in kgCO2/kg Chemical?

Dear Jutta,

Data on environmental impact per kg of chemical may be found e.g. in an EPD of the chemical published by the supplier. If not available, the supplier may be contacted to collect supplier-specific information. If that is not available, LCA practitioners normally use database or generic data, which are available both in free and commercial databases. The quality of you data, e.g. age and representativity, should always be assessed and may be more or less suitable depending on the context.

Best regards,
Kristian Jelse, Secretariat
