Miljönär-vänlig is a certificate awarded to organisations and businesses that are focussed on reusing, renting and borrowing. The certified organisations are listed on the project website. A searchable map makes it easy to find sustainable organisations close to you.

The purpose of the project is to promote a more sustainable lifestyle to young people in Sweden. Besides the certificate, it also encompasses a regularly updated Facebook page, which as of writing has 1,200 likes.

During the EWWR, the week will be recognised on the Facebook page. Each day the page will present one focus area, such as second hand shopping or renting instead of buying.
