BONSAI is organised as a not-for-profit association, with the aim that all data, software and algorithms to produce “product footprints” are maintained as open source.

Specific deliverables may be funded by specific donations and/or as government research projects, but as with Wikipedia, we rely on the general public to support the basic costs of running a database and website.

Please consider making a donation of 20 €, 40 € or more. Whatever you can spare will be put to good use with us.

You can also support us by becoming a member. Most decisions around BONSAI are made in public consultations using social media where anyone can participate. But as a member, you provide a sustained support, and will have access to vote at our general assembly. We welcome any private person as member at an annual membership fee of 150 €.


Includes 1 year membership.

* Recurring payments will be debited until you notify us to stop. We'll send you an email receipt for each payment, which will include a link to the cancellation instructions.
