GSES Sustainable Footprint®


Sustainable Footprint® for products, resources, projects, buildings 

As an extension of the GSES® system, the NDI has developed a three-stage generic product certification which measures products, projects, buildings & resources from all different sectors. With the Sustainable Footprint method the NDI offers a global solution for the generic measurement of products, projects, buildings & resources. The Sustainable Footprint measures on 3 pillars: Circular, Environmental & Health as described below;

Circular Footprint®

The NDI & SGS Search developed the Circular Footprint suitable for products, projects & buildings. In order to properly measure all products from all different sectors on circularity, we have developed a generic method that can be used worldwide. The method can also be used for projects from September 2018. End users of products and raw materials can see exactly how circular their end product is by using a QR code or NFC tag. the CPF® index and why. The QR code linked directly to the international linked database in which all information about the product such as the production process, the used raw materials and elements, circular bussines model, waste processing method etc can be viewed. The CPF is generic, workable, scalable, and based on existing standards as Cradle to Cradle and EMF.

Environmental Footprint®

The NDI created the LCA certification; the Environmental Footprint for products, projects and buildings. The EPF® certification is based on the ISO 14040 and the PEF, which will be launched in 2018. In order to properly measure all products from all different sectors on an environmentally friendly production process, we need a generic method that can be used worldwide. End users of products such as companies but also consumers can see exactly how environmentally-friendly or polluting their product is produced using a QR code or NFC tag.


Health Footprint®

The NDI & Royal Haskoning DHV are developing the Health Product Footprint. The HPF® certification will be launched in 2019. In order to properly measure all products from all different sectors on health risks, we need a generic method that can be used worldwide. End users of products such as companies and consumers can see exactly how healthy or harmful their purchase is based on a QR code or NFC tag.


GSES Sustainable Footprint® Trademark

If the product reaches the minimum qualification of the Sustainable Footprint standard, you can use the Sustainable Footprint label of the GSES System on branding, packaging and in media exposure. 






We present you the Circular Product Footprint- CPF of a Merford crane cabine!  A large proportion of the Merford products contribute to a sustainable working and living environment. Consider, for example, the fire doors, acoustic absorption materials and Merford ergonomic operator cabins. In addition, more and more of the Merford products, whether or not partly, are constructed from recycled materials. A good example of this is the Ecocab NEO, the crane cab that consists of recycled and recyclable materials. This is why the National Sustainability Institute is very proud of the Ecocab NEO as a test case for the Circular Product Footprint.

“The NDI and SGS have tested different products from different sectors and are launching the Merford Cabins test case in June 2018. Merford Cabins measures its Ecocab NEO through the Circular Product Footprint.This cabin already has a Cradle to Cradle certificate and that makes this case just so interesting! ” according to Kelly Ruigrok, founder of the NDI, GSES and developer of the Circular Product Footprint.

“Merford Cabins has been investing for decades in providing sustainable solutions for crane operators, so that they remain vital and can carry out their work in a pleasant and professional manner.” With the Ecocab NEO we are just going one step further. the products in the industrial sector can also be produced with the utmost respect for people and the environment The Cradle to Cradle certificate is a nice reward for this innovation, but in the end it is all about the fact that everyone looks a bit further than normal. we are proud to be involved in this project of the NDI. ” according to David Buschman, general manager of Merford Cabins.


TrustLube measures their lubrication systems with the GSES Sustainable Footprint

TrustLube lubrication systems are durable, effective and efficient. They lubricate completely independently, including all parts that are poorly or not accessible to people. The lubrication points are provided with an exact but minimal dosage of lubricant. All TrustLube installations are suitable for both oil and veterinary surgeons. TrustLube has its own assortment of lubricants that is non-toxic and therefore not harmful to underwater life!

Thanks to their sustainable intrinsic values, TrustLube now also provides insight into their own organization and in their supply chain with the Global Sustainable Enterprise System.
The products ans installations of TrusLube are measured with the Circular Product Footprint-CPF, the new method developed by the National Sustainability Institute & SGS Search. In addition to the Merford Cabins test case, SGS and the NDI will soon present the test results of the TrustLube case.
Circular Product Footprint

The NDI has entered into an partnership with SGS to develop the Circular Product Footprint, a generic method for measuring resources and products on sustainable and circular qualifications.

Products that are also validated or certified, with the Circular Product Footprint method, get a QR code on their product with the Certified CPF logo. End users of products and raw materials can get information thru the QR code about how circular their end product is. The Circular Product Footprint is a workable, generic and international method.

“With the Circular Product Footprint method, we offer a global solution for the generic measurement of the circularity of raw materials in finished products and projects at a later stage, enabling us to create awareness among end-users of a product through this method." According to Gert Jan Vroege of SGS Search.


Philips MRI-scanner bestaat voor 91% uit hergebruikt materiaal (Trouw)

Het Nationaal Duurzaamheid Instituut (NDI) introduceert een nieuw keurmerk waarmee inzichtelijk wordt gemaakt of een product duurzaam is, de zogenaamde ‘Circular Product Footprint’. De Philips Achieva 1.5 SE, een MRI-scanner, behaalde een score van 91%. Dat wil zeggen dat 91% van het apparaat bestaat uit ‘refurbished’, of hergebruikte, materialen.

Duurzaamheid als integraal onderdeel van de strategie

“Voor ons is dit een pilot. Deze nieuwe berekeningsmethode helpt om ons beleid verder te ontwikkelen. Maar uiteindelijk bepaalt de klant of deze informatie voor hen iets toevoegt”, vertelt Eelco Smit, Director Sustainability bij Philips. “Duurzaamheid is een integraal onderdeel van onze strategie. Wij weten dus precies hoeveel gram koper, staal en kunststof in onze mri-scanners zit, waar dit vandaan komt en hoeveel hiervan gerecycled is of niet.” 




Designer Tjeerd Veenhoven, winner of the Global Change award from H&M and owner of Studio Tjeerd Veenhoven discovered new sustainable materials for the product and fashionindustry. His latest creations: Palmleather and AlgaeFabrics.

Palmleather is special because it is made from the fallen leaves of the Areca Palm tree that grows in the South of India. This fantastic natural resource is still largely unused. Thanks to a simple and ecologically principle, these dry leaves are now processed into a flexible and strong material; Palmleather. In small factories in India, the leaves are collected and upgraded to palm leather by local workers. All kinds of products are made on site, from slippers to bags. It is a beautiful material where both the local economy and nature as a whole is benefiting from.

“When I came into contact with the National Sustainability Institute I got to know the GSES system, Kelly Ruigrok from NDI and Gert-Jan Vroege from SGS presented me the Circular Product Footprint method and the CPF method was very suitable for my materials and products. This was a fantastic opportunity for Palmleather to prove its sustainability. ” Thus Tjeerd Veenhoven.

The Palmleather CPF according to the Studio Tjeerd Veenhoven process is 95.2%. The textile industry is looking for substitute raw materials that are sustainable, circular and scalable, for which Palmleather is now demonstrably suitable.

“Now that we have developed and tested the Circular Product Footprint method for different products and raw materials in different industries, it is only a matter of time until certification is developed and then all products can be certified using the Circular Product Footprint method.” Said Kelly Ruigrok, NDI.

“Several big brands have already shown interest and together with O’Neill Footwear a successful collection of sandals has been brought onto the market! Sustainable design is finally really on the agenda, and it helps if you can make circular claims compliance. my customers also certify their end products on the basis of my certified materials! ” Thus Tjeerd Veenhoven.
