The product categories we include are shown on the right.

A partnership with INSIDE/INSIDE includes a few standard elements. In addition, INSIDE/INSIDE is open to further expansion of a partnership based on the wishes of your organisation.

Partnership benefits

  • 10 products*, including your own (product) description and logo in the database
  • Your organisation’s profile on the website
  • Join INSIDE/INSIDE (networking) events and promote your own events and developments through INSIDE/INSIDE
  • Contribute to the further development of INSIDE/INSIDE

*Definition of a product: a product or material consists of one or more products based on the same EPD.


Including your products on INSIDE/INSIDE requires investment. The investment includes a yearly contribution to INSIDE/INSIDE and the costs to get EPDs. The costs for creating and verifying the EPDs are paid to your LCA-expert.

1. Partner investment INSIDE/INSIDE

  • €2500 yearly membership INSIDE/INSIDE
  • If you wish to include more than five products in the database, an extra €250 per product is required. A sliding scale is available from 10 products onwards.

Producers of one product can join as a Single Product Partner and pay €1500 as membership fee.

An overview of partner and product costs can be found here. Membership can be stopped yearly by sending a written confirmation before 1 October for the next year.

2. Investment to acquire a verified EPD

Products must have an EPD to add them to INSIDE/INSIDE. Creating and verifying the EPDs must be done by a qualified LCA-expert. The prices below give an indication of the costs and depend on the complexity of a product’s production process and how easily is the required information available. Read more details on how to acquire an EPD here. The minimum costs for an EPD per product are:

  • Creating an LCA (or a series of LCAs) costs around €2000 including generating the EPDs. An EPD is valid for five years.
  • Verifying a (series of) EPDs costs around €1250

*The time required to gather data about the production process and suppliers is not included. Costs can be reduced by licensing an LCA tool and running the LCA calculations in house.
