Join the Global Sustainable
Enterprise System! 


Does your organization really want to make an impact? Then take part in 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 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? There is no standard, not one ISO standard that covers the entire load.

The solution

the GSES® System
The Global Sustainable Enterprise System (GSES®) is an international generic sustainable standard that has been set up to support organizations in making things more sustainable and making them visible and traceable. The GSES® system is:

  • an overarching and international standard
  • Workable for any kind of organization
  • Open source
  • Can be used universally with existing certifications, initiatives and labels
  • GSES® scheme has been submitted to the RvA for evaluation (Accreditation Board)
  • Independent international audits and validation
  • Represented in 77 countries


We proudly present you the home of sustainability. The house that shows all facets of sustainability.
The GSES® system determines the baseline, Quick Wins and long-term goals of the organization and / or the chain and monitors these. The basis of the system are four pillars:

4 Pillars

  • Corporate social responsibility (ISO 26000)
  • Socially responsible procurement (ISO 20400)
  • CO2 Reduction (including CO2) (ISO 14064-1)
  • Circular enterprise (BS 8001)

It is possible to follow the pillars separately. It is also possible to obtain partial exemptions based on already obtained certificates such as Cradle to Cradle (C2C), CO2 performance ladder, CSR performance ladder, Fairwear, PSO performance ladder etc.

In the GSES System three levels are measured and targetted:

3 levels

  • company level
  • chain level
  • product 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.

For companies: The GSES® system is currently operational for companies from all different sectors.

For government organizations: government organizations and administrative bodies can also map their own sustainability policy and buy 100% compliance socially responsible and circular with the GSES® system. The GSES® system supports procurement in the fields of CSR, SRI, CO2 reduction and circular enterprise.

For consumers: join the world’s largest network of sustainable change agents and gain insight into your personal ecological footprint and your sustainable lifestyle. (from late 2018)


As an extension of the GSES® system, the NDI has developed a three stage generic product certification with which all products from all different sectors can be measured. The Sustainable Product Footprint. With these methods the NDI offers a global solution for the generic measurement of products, resources & projects.

The GSES Sustainable Product Footprint consisted of 3 pillars:

Circular Product Footprint®

The NDI & SGS Search have developed the Circular Product 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. 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. the CPF® index and why. The QR code linked directly to the global database in which all information about the product and the scores can be viewed. Measure your products according to the Circular Product Footprint method! Contact us!

Environmental Product Footprint®

The NDI is working on the following international generic product certification; the Environmental Product Footprint. 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.

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.

Health Product Footprint®

The NDI works with Royal Haskoning DHV on the Health Product Footprint. The HPF certification will be launched in 2018. 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 on the packaging of the product.

Participation proces

Access to the GSES® system: As a GSES member you will receive the GSES System Manual and access to the platform and the organization will already provide certificates for the exemptions.

Company level: You can now do an extensive self-assessment through the manual and on the platform. This clarifies the Baseline current situation of the own organization.

Chain level: you invite your own suppliers to also fill in the GSES self-assessment on the pillars you have chosen. So you rank and encourage your suppliers to do business sustainably.
Product level: If the organization has a product, it can measure this product according to the product methods of the GSES, the Circular Product Footprint, the Health Product Footprint or the Environmental Product Footprint.

Validation: Your organization can now request document validation or external audit for validation or certification. Certification is voluntary for participants. We value access of many participants and hope to stimulate working on sustainability, also when organisations do not want to spend resources on certification.

Publication: If reviews have been validated, organizations can publish the ranking and scores, after which the ranking will be online on the GSES platform.



Your organisation’s benefits

The efforts in the area of making the organization more sustainable are demonstrable after GSES certification and compliance for customers and contracting parties.

  • As a participant in GSES, the organization starts monitoring sustainability in a comprehensive and structured way.
  • Your organization is included in the international GSES® register and is therefore recognized locally, nationally and internationally as an organization that acts sustainably. This is advantageous if the organization participates in tenders.
  • Your organization takes steps that save energy, so that costs will be reduced.
  • Your organization innovates, resulting in greater efficiency or becoming smarter in solving sustainability problems.
  • Engaging in these types of processes usually perceives employees as valuable and motivating, which increases their loyalty and increases the attractiveness of the organization to the outside world.
  • Innovation gives opportunities for publicity that can yield a lucrative spin-off.
  • With GSES® certification, the supply chain becomes transparent in all areas of sustainable business. This will make your company is an interesting party or supplier for other organizations.
  • Your organization can display the GSES logo on its own products as well as on marketing and PR material.
  • Greater costumer loyalty

Greater benefits

As more and more organizations come closer to the GSES standard, this will ultimately have an effect on:

  • that customers make more sustainable choices as they get more sustainable supply, especially if they see evidence that products are truly sustainable.
  • Given that sustainability is not just a trend, people will become increasingly aware of their necessity and increasingly choose to produce and consume without harm to future generations.
  • Spill-over to other parts of the chain that will also become more sustainable, thanks to an invitation system to the suppliers.
  • Reduction of greenhouse gas emissions • Reduction of plastic soup and other pollution • Improvement of working conditions elsewhere in the world
  • Improvement in the situation regarding the 17 Sustainability Goals of the UN.
  • Decrease in the growth of the use of raw materials.
  • Decrease in deterioration of biodiversity and eventually hopefully improve it.
