How the figures were calculated
SKZ calculated the product carbon footprints using established, science-based methods and GaBi life-cycle-assessment software, based on DIN EN ISO 14040, DIN EN ISO 14044 and DIN EN ISO 14067. Each certificate states that the comparison is subject to limitations; please consult the linked certificate for the scope, assumptions and full wording.
