Label Eco-Efficiency Analysis by BASF
See excerpt from website...
BASF SE has developed a label for products that have been evaluated by an Eco-Efficiency Analysis. The awarding of the label is dependent on demanding requirements: After conclusion of the analysis a third party evaluation (peer review) is requested. Furthermore, publication of the results of the analysis will be undertaken via internet.
The label can be carried on for three years. After that period, a revision of the analysis is required due to cover market developments and product diversity.
