This metric is based on Greenpeace Spain's evaluation study "Ranking of supermarkets' plastic footprint" carried out in late 2018 and late 2019.

Although the behaviour of companies with regard to the use and disposal of plastic at their points of sale should be included in our previous metric ""2.7 Packaging management"" we believe that due to the impact of this material on the environment it deserves to be treated individually.
For this we have used the most complete and rigorous corporate evaluation study on plastic use that currently exists in Spain and which specialises in the rating of supermarkets, such as this "Greenpeace Plastic Footprint Ranking".

Some parameters that Greenpeace evaluates in this ranking may be redundant with those considered in our section on Waste and Materials Management, but with this we wanted to give greater robustness to the evaluation in this area of the Circular Economy given its great impact on our environment and in the opinion of society.
