Join the Global Sustainable Enterprise System!


Does your organization really want to make an impact? Join the Global Sustainable Enterprise System (GSES®). The GSES® system covers all facets of sustainable entrepreneurship, is suitable for all sectors and is based on the best internationally accepted standards. Make sustainable ambitions and milestones visible and transparent and lets change the world!

The Challenge

The proliferation of quality marks, certifications, software systems and initiatives in the field of sustainable, socially responsible and circular entrepreneurship is endless and entrepreneurs, governments and companies no longer see how to make an impact because we have no overview.Entrepreneurs and other managers are increasingly opting to make the organizations where they work more sustainable. But which facet of sustainable entrepreneurship should you focus on to really make an impact? There is no standard that covers the entire load.


The solution

The Global Sustainable Enterprise System (GSES®) is an overarching generic sustainability standard that is created to support organizations in making themselves and the world more sustainable


The GSES® system:

  • Is an overarching and international standard
  • Is workable for any kind of organization
  • Is used as procurement tool
  • Can be used in tender management
  • Is used as marketing tool 
  • Can be used universally with existing certifications, initiatives and labels
  • Is third party assessed by external audits and validations
  • Is represented in 77 countries
















GSES as procurement tool

The GSES platform can be used as a procurement tool. The Supplier functionality on the online GSES Platform gives every participant the opportunity to invite and rank  their suppliers on standardized and internationally accepted sustainability themes as CSR, Responsible Procurement, CO2, Circular Economy, Health & Safety. After the suppliers publishes the scores of the theme of your choice in the form of a validated assessment, a supplier ranking will appear on your supplier dashboard. Contact us for more information.

GSES as tender tool

Use the GSES platform as tender tool! Rank the suppliers for your tender on sustainable themes of your choice at the organizational level. Measure your tendering projects at project or building level on circular and environmental performance linked to purchase orders and standardized burden of proof guidelines. Contact us for more information.


We present you the house of sustainability. The house shows all facets of sustainability and is a visualization of the GSES System. Every pillar represents an assessment.
The GSES® system is based on 3 levels:

3 levels of measurement:

  • organizational level
  • supply chain level
  • product & project level


The translation of the 17 Sustainable Development Goals (Sustainable Development Goals) of the United Nations is also included in the GSES system. By integrating them into the system, we provide organizations with tools to pick up their part to achieve the SDGs.

Sustainable Footprint® for products/ projects 

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;

The GSES Sustainable Footprint consists of 3 pillars:

Circular Footprint®
The NDI (National Sustainability Institute) & SGS Search have developed the Circular Footprint. In order to properly measure all products from all different sectors on circularity,  we have developed a generic method that can be used worldwide. End users of products and raw materials can see exactly how circular their end product, project or building is by using a QR code or NFC tag. The QR code linked directly to the GSES global database & the Sustainability Codex in which all information about the scores can be viewed. Measure your products, project or building according to the Circular Footprint method! Contact us!

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, In order to properly measure all products, projects & buildings on an environmental performance we needed a generic method that can be used worldwide. This method became the EPF. End users of products can see exactly how their product or project is ranked on environmental performance using the QR code or NFC tag on the packaging or branding of the product/ project.

Health Footprint®
The NDI (National Sustainability Institute) & Royal Haskoning DHV are developing the Health Product Footprint. 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 on the packaging of the product.






To test out the Circular Product Footprint we present the CPF of a Merford product. 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 joins GSES system and measures their installation with the Circular Product 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.

Full overarching sustainable product certification

The Circular Product Footprint is the first of a three-stage generic overarching product certification that allows all products from all sectors to be measured. Subsequent to the circular product footprint, the environmental product footprint will follow in due course. The EPF certification is based on ISO 14040 and the PEF. This will be launched by the NDI in 2018. In order to properly measure all products from all different sectors and to have an environmentally friendly production process, we need a generic method. The NDI also works on the Health Product Footprint with Royal Haskoning DHV. The HPF method and HPF certification are also launched in 2018. The EPF and HPF are certifiable both separately and in addition to the CPF. As in the GSES system at company and chain level, the product certifications will accept exemptions that comply with the standard at product level. Example of exemptions: GRS, Cradle to Cradle, Bluesign.


Philips measures MRI scan on CPF method




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.
