Rank a Brand

How sustainable is your favorite brand?

Who we are


Rank a Brand is an international community of responsible consumers who want to buy sustainable and fair products or services. Rank a Brand exist to enable consumers to make responsible shopping choices and to put pressure on brands to become more sustainable, socially responsible and transparent.

Rank a Brand was founded in 2009 by Niels Oskam. Under his leadership Rank a Brand has become one of Europe’s largest brand-comparison sites on sustainability and corporate social responsibility.

If you want to join our community of responsible consumers, support our work and have a say in the sectors and brands we rank and which criteria we apply, you can become Friend of Rank a Brand for €25 per year, or more if you can afford.


Rank a Brand would not exist without the active participation of a large group of volunteers. These rankers research the sustainability and social responsibility of sectors and brands. 

The rankers are the heart of Rank a Brand. This group makes sure all of the brands we have ranked have up-to-date scores on our website. On a voluntary basis, they search through brand websites, CSR reports and other public sources to find the answers to our questions.

Other volunteers

Rank a Brand also has a group of volunteers who do other roles, for example in communication, fundraising, website and IT.

You can help us too

To date, more than 50 rankers are involved in our research of sectors and brands. And new rankers join us regularly. Curious who we are? Check out some of our testimonials.
