All suppliers of all products in Zevij-Necomij’s 4tecx line are asked to share these products’ sustainability information with Zevij-Necomij through the GSES platform.

Participation is not enforced, however it is highly encouraged and appreciated  in order for Zevij-Necomij to meet their sustainability goals. 

The costs for this project are zero, all the suppliers’ membership fees and participation on the platform are fully covered by Zevij-Necomij to encourage participation. This is limited to the audit of only products in the 4tecx range, however as a supplier if you are interested in a GSES membership for your own needs, please contact [email protected] and we’d be happy to provide you with all the necessary information.  

Your first step is to register your user and organization on the GSES platform:  

https://platform.gses-system.com/register 

You can submit data via the platform, where you will receive a request from Zevij-Necomij to submit data for each specific product you supply to the 4tecx line. Exact instructions on how to do this will be given to you during your workshop with GSES. 

Only Zevij-Necomij will have access to your product data. Additionally, you have the option to hide your Bill of Materials from Zevij-Necomij, so the only information they have access to is the sustainability information generated by the Bill of Materials, and the other uploaded evidence.  

Yes, although, having an LCA means you do not need a Bill of Materials. You can submit your LCA values in order to calculate a score that is more specific and accurate to your product than the Bill of Materials method. The method of providing this information will be shown to you in the workshop. 

The scope of the Nature Impact Score is Cradle to Gate as standard. If you supply additional data and evidence for the gate to market transport, this scope can be increased and lead to a better score. 

For building products, the GSES platform also allows you to add use phase and end-of-life data, which is visualised on the product score card, though not included in the score. 

After you have finished uploading the data and submitting it to Zevij-Necomij, your work is done. Zevij-Necomij then submits the products for an audit through GSES partner Audit Independer.  

Audit Independer subsequently assigns the audit to an accredited conformity

While submitting data, you have the option to save a draft and revisit the submission request again as many times as you want. If you have already submitted the data, and need to change the data after this point, you can reach out to [email protected], or submit a ticket directly on the platform. After which, we can resend you the data request for you to edit the data as you see fit.  

Please make sure to flag this in good time, as once the data reaches the Auditor, changing it is not easily done anymore.  

No, Kwantum will decide for which products you need to supply data. This mainly depends on the materials used.

A certificate is not always mandatory, but you must be able to demonstrate the origin of your raw materials. This can also be done via a written due diligence statement from your supplier. Contact us if you need help preparing this.

Yes. The GSES platform offers a bulk upload via Excel. You can upload a completed template with all product data at once. The template is available after logging into the platform.

Products without approved product data in GSES can no longer be sold via Kwantum after 30 December 2026. This is a legal EU requirement that Kwantum must comply with. Timely submission is therefore essential. 

No, Leen Bakker will decide for which products you need to supply data. This mainly depends on the materials used.

• Data ownership remains with your organization. GSES only processes the data and does not claim ownership.  
• Certificates (e.g. ISO, CO₂ Performance Ladder) are uploaded by you and validated by an independent certifying body. 
• Certificates cannot be downloaded by others and are only visible in summary form (logo, status, validity). 
• Assessment answers are verified and shown on your scorecard; answers cannot be edited after submission. 
• Burden of proof (e.g. internal documents) is stored in a Virtual Safe and only accessible to you and the auditor. The documents are not visible on your scorecard. 
• You control scorecard visibility: set your ESG Scorecard to Public (visible to all) or Private (only visible to you). 
• If scorecard visiblity is set to private, other GSES members can still request access to view your scores; you will recieve a notification and can accept or decline the request.

Joining GSES is highly encouraged. AVEX is placing increasing emphasis on sustainability and transparency across its supply chain. By sharing your sustainability data via the GSES platform, your organization shows commitment to future-proof, responsible business. It helps strengthen your position as a preferred supplier and ensures you’re aligned with AVEX’s long-term goals. 

To share the required sustainability data with AVEX, your organization needs a GSES Pro Membership. This enables you to create and share an ESG scorecard, manage certificates, track CO2 emissions, and collaborate with up to 5 colleagues. You can upload existing certificates and complete assessments, which are then independently validated through the GSES platform. 

AVEX suppliers receive a discounted GSES Pro Membership based on annual turnover: 

• €1,900/year (turnover €0–10M) 
• €2,500/year (turnover €10–100M) 
• €3,700/year (turnover >€100M) 

This includes access to the organizational module and 4 desk audits per year for the required GSES pillars. The contract has a duration of 3 three years.   

All prices are excl. VAT. 

The largest time commitment for your organization is in qualitatively answering the assessments and collecting the underlying documents that serve as evidence. Below is an overview of the processing times.    

Time commitment and lead time:   

• Create an account: 2 minutes for you as a user (name & email address) to register your organization.   
• Uploading certificates and requesting validation: up to 5 minutes.

Lead time of independent audit by certifying body:   

• Validation of 1st line certificate: 2 working days. 
• Validation 2nd-line certificate: up to 10 working days. 
• Verification of Assessments by means of a desk audit: 10 – 15 working days. 

You may need various colleagues to fill in the assessment, this can differ per organization but also per GSES Pillar. Oftentimes, colleagues from a sustainability team or the contract and procurement team have the required information. You can give up to 5 colleagues access to your organization’s online environment.

Data ownership and accessibility.  

• The information you provide remains the property of your organization. GSES will only have the right to process the data, without transferring ownership rights.  
• You always have full access to your organization’s own information and can view it.  
• Important: After submitting an assessment, you cannot edit your answers anymore.  

Processing and visibility of certificates (ISO, CO2 Performance Ladder, Ecovadis, etc.)  

• Certificates are uploaded by you and forwarded to an independent certifying body for validation.  
• You can always view and/or delete your organization’s certificates.  
• The scorecard will display the certificate’s logo, including its validation status and validity.  
• The score report states whether a certificate contributes to your score. The certificate itself cannot be downloaded by others.  

 Processing, visibility of assessments, and burden of proof

• When filling in a questionnaire, the following elements are recorded:  
  • Answer: multiple-choice options from the GSES Standard  
  • Context: explanation for the auditor  
  • Burden of proof: internal documents as burden of proof  

How is this processed and visible?  

• The answer will be visible on the scorecard after verification.  
• The burden of proof is stored in a secure safe. Only your organization and the auditor have access to this. This is not visible on the scorecard.  

Visibility and scoring management  

• You decide who can view your scorecard: Public (visible to everyone) or Private (visible only to you).  
• Even with a private setup, customers can link you as a supplier, but they won’t see scores.  
• Does another GSES Member want to see your scores? They can send a Visibility Request. You will receive an email and can accept or deny access. 

Organizations are fully responsible for the accuracy and ownership of any data uploaded to the platform. By submitting data, they confirm it is truthful and accurate to the best of their knowledge. 

Auditors independently assess whether the data is verifiable and meets the required standards. The platform itself is not responsible for the content or accuracy of submitted data. 

Are you excited and ready to get started? We will help you on your way. On this landing page you will find all the steps you need to follow in the “Getting started with GSES” section.  

In addition to the functionalities that a GSES Pro membership brings, your organization can do much more with the GSES platform, for example, the GSES platform can:   

• Enter and validate sustainability information about your products.  
• Map the sustainability performance of your supply chain.
• Use other modules on the platform, such as the CSRD module, the event module, and/or the asset module
• Compare suppliers on sustainability performance in the GSES database.  

If you want to know more about the above functionalities and possibilities for your organization, book a demo or contact the GSES Support Team at [email protected]. 

De kosten voor jouw organisatie zijn afhankelijk van welke functionaliteiten je gebruikt. Als je alleen gegevens wilt ontvangen, heb je enkel een lidmaatschap nodig. Als je ook gegevens wilt aanleveren (zoals productregistratie en datavalidatie), betaal je per invoer een vast bedrag bovenop de basislidmaatschapskosten.

Bekijk het onderstaande prijsoverzicht voor meer informatie.

Je kunt beginnen door jezelf en je organisatie hier te registreren.

Zodra je dit hebt gedaan, neemt een teamlid van GSES contact met je op om de behoeften van jouw organisatie te bespreken en een conceptcontract aan te leveren.

Na ondertekening van het contract plannen we een workshop voor jou en je collega’s om te leren hoe je aan de slag kunt gaan.

Het type GSES-lidmaatschap dat jouw organisatie nodig heeft, is afhankelijk van de functionaliteiten die je wilt gebruiken.

Gegevens kunnen op twee niveaus worden aangeleverd.

Organisatie:

Om inzicht te krijgen in de duurzaamheids­prestaties van je organisatie kun je beginnen met het uploaden van alle certificaten die jullie organisatie al bezit. Deze worden vervolgens gevalideerd en leveren jullie organisatie een initiële GSES-score op. Als jullie organisatie geen certificaten bezit of als je aanvullende informatie wilt aanleveren die niet in de certificaten is opgenomen, kun je ervoor kiezen om de zes pijler­assessments in te vullen. Elk assessment bevat ongeveer 15 vragen. Houd er rekening mee dat je bij het invullen van deze assessments bewijsmateriaal moet uploaden in een Virtuele Kluis. Dit bewijsmateriaal wordt geverifieerd door een externe, onafhankelijke auditor en resulteert in een GSES-score op het platform.

Voor meer informatie zie: hier

Producten:

Productinformatie kan op twee manieren worden aangeleverd: ofwel door gegevens uit een LCA aan te leveren, waarbij de LCA dient als bewijs voor de data, ofwel door via het platform een gedetailleerde BoM (Bill of Materials) aan te leveren.

Producten:

Productinformatie kan op twee manieren worden aangeleverd:

• Door gegevens uit een LCA (Levenscyclusanalyse) te leveren, waarbij de LCA als bewijs dient voor de gegevens.

• Of door een gedetailleerde stuklijst in te vullen via het platform.

Voor meer informatie, zie: hier

Jouw organisatie bepaalt zelf wie er toegang heeft tot de data van de organisatie.

Belangrijk om te weten is dat je duurzaamheidsdata van producten kunt delen zonder daarbij de BoM (Bill of Materials) of BoI (Bill of Information) van het product openbaar te maken.

DPP-data en EUDR-data kan worden beheerd via het GSES-platform en wordt weergegeven op de productscorecard.

Door je supply chain te koppelen aan het platform, maakt GSES het eenvoudig voor leveranciers om gegevens aan te leveren.

Ja, omdat niet alle LCA’s gelijk zijn, moet de LCA worden geüpload op het platform en onafhankelijk gevalideerd worden.

Daarnaast houdt de GSES Nature Impact Score rekening met extra indicatoren die verder gaan dan een LCA en die afzonderlijk moeten worden opgegeven.

De standaard scope van de NIS (Nature Impact Score) is Cradle to Gate.

Wanneer je aanvullende gegevens en bewijs aanlevert over het transport van de poort tot aan de markt, kan de scope worden uitgebreid — wat kan leiden tot een hogere score.

Voor bouwproducten biedt het GSES-platform bovendien de mogelijkheid om gegevens over de gebruiksfase en end-of-life toe te voegen. Deze informatie wordt weergegeven op de productscorecard, maar telt niet mee in de uiteindelijke score.

Nadat je alle gegevens hebt geüpload, kun je een datavalidatie aanvragen via onze partner Audit Independer.

Audit Independer wijst de audit vervolgens toe aan een erkende conformiteitsbeoordelingsinstantie (zoals Kiwa of Control Union) die de audit uitvoert. Zodra de audit is afgerond, ontvang je hierover een bericht van GSES.

Het aanvraagproces voor een audit is volledig geautomatiseerd. Dit betekent dat zowel Audit Independer als GSES direct kosten maken zodra je een audit aanvraagt.

Als er fouten zijn gemaakt in de aangeleverde informatie, kunnen wij de audit niet aanpassen of terugbetalen.

To share the required sustainability data with the Royal Schiphol Group, your organization needs a GSES Pro membership. This membership allows you to create and share an ESG scorecard, manage certificates, comply with GSES assessments, track CO₂ emissions, and collaborate with up to five colleagues.

You can upload your organization’s existing certificates to receive a baseline assessment and complete the full GSES assessment process. A Pro membership includes four annual assessment reviews (desk audits), all of which are independently validated through the GSES platform.

With your ESG scorecard, you can monitor your sustainability performance, set future goals, communicate and share your data with clients and other stakeholders, and leverage your performance for external communication purposes.

Schiphol wants to work with its suppliers towards a sustainable and future-proof airport. To do this in a transparent and measurable way, Schiphol requests suppliers to share verified sustainability data. This helps to gain insights into the supply chain and to track progress together.

Yes. The request to provide sustainability data is part of Schiphol’s Supplier Check-In process. The actual data collection and verification takes place separately through the GSES platform, but it is considered an integral element of the Check-In.

An important part of the Check-In is also the continuous improvement of your GSES score on the platform.

• Enter your sustainability data into the GSES platform.
• Have this data verified by an independent certifying body via the platform.
• Obtain a GSES membership, which is required to complete this process.
• Work on improving your GSES score over time, as part of the Supplier Check-In.

• Asset suppliers
• IT/Services suppliers
  For both groups, a specific data request has been formulated to ensure that the information collected is relevant to the products or services delivered.

Participation in the GSES platform is part of the Supplier Check-In. In addition, it may also be a requirement in Schiphol tenders. We therefore strongly advise suppliers to participate, as it can influence both ongoing and future business opportunities with Schiphol.

The Sustainabuild Collective (SBC) is a cross-sector foundation that aims to streamline information availability and sharing for all market players in the Netherlands and Belgium.

The goal: to promote uniform, reliable, and transparent sustainability data in the construction sector and establish a single standard to communicate with all parties in the value chain. All these parties, from suppliers to costumers, will be asked to join.

The costs your organization bears are dependent on which functionalities your organization uses. If you only want to be able to receive data you only need a membership. If you want to supply data each data entry (i.e. product registration and data validation), this will cost a fixed sum, in addition to the base membership fee. See the price chart below.

SBC sees the NMD (Stichting Nationale Milieudatabase) as a very valuable tool as a Dutch database of LCA data for construction materials, while the GSES Nature Impact Score is a cross-sector sustainability rating that translates product and supply chain impacts on nature into an accessible score. To support data entries in the NMD, SBC and GSES have come to the agreement that data available in the NMD can be uploaded to GSES free of charge for the coming three years.

A further collaboration between SBC and the NMD is being explored.

DPP data can be managed on the GSES platform and is shown on the product scorecard. By connecting your supply chain to the platform, GSES facilitates data entry from suppliers.

Materials included in the scope of EUDR are flagged on the GSES platform. For these materials, you can collect due diligence statements and certificates and gain an overview on your progress in an integrated EUDR dashboard.

Getting Started with GSES

You can start by registering yourself and your organization here.

When you have done so, a team member of GSES will contact you to verify your organization’s needs and provide a concept contract.

After signing the contract, we’ll schedule a workshop for you and your colleagues to help you get started quickly and efficiently.

You can also plan your own (refresher) workshop anytime via the landing page.

What GSES membership your organization needs is based on the functionality your organization will use.

To get a better understanding of the possible functionalities we advise you to book an online GSES-demo trough the SBC landingpage.

Your organization decides who has access to your organization’s data.

Important to note is that you can share product sustainability data without having to disclose the BoM (Bill of Materials) or BoI (Bill of Information) of the product.

Data can be provided on two levels.

Organization:

To gain insights in the sustainability performance of your company you can choose to start by uploading all the certificates your organizations already holds. These will subsequently be validated and give your organization an initial GSES-score. If your organization does not hold any certificates or you want to provide additional information not captured in the certificates you can choose to fill the six pillar-assessments. Each containing ca. 15 questions. Note that to fill these assessments you will have to provide evidence into a Virtual Safe. This evidence will be verified by an external independent auditor and result into a GSES score on the platform.

For more info please see: here

Products:

Product information can be supplied in two ways, either by supplying data from an LCA with the LCA as evidence for the data or by supplying a detailed BoM through the platform.

For more info please see: here

Yes, because ‘not all LCA’s are created equal’ the LCA has to be uploaded on the platform and independently validated.

Furthermore, the GSES Nature Impact Score considers indicators beyond an LCA, which must be declared separately.

The scope of the NIS is Cradle to Gate as standard. If you supply additional data and evidence for the gate to market transport, this scope can be increased and lead to a better score.

For building products, the GSES platform also allows you to add use phase and end-of-life data, which is visualised on the product score card, though not included in the score.

After you have finished uploading the data you can request a data validation through our partner Audit Independer. Audit Independer subsequently assigns the audit to an accredited conformity assessment body (i.e. Kiwa or Control Union) who performs the audit. When your audit is done you will receive a message from GSES.

The audit request process is automated; this means that both Audit Independer and GSES incur immediate costs when you request an audit. If you have made any mistakes in the information you have provided, we will not be able to adjust the audit or to reimburse you.

Data can be edited up until the point that you request an audit. The audit request process is automated; this means that both Audit Independer and GSES incur immediate costs when you request an audit. If you have made any mistakes in the information you have provided, we will not be able to adjust the audit or to reimburse you.

The verification results of the ABN AMRO Questionnaire are accessible to ABN AMRO.

The results of the EcoVadis validation based on the GSE-Metastandard and the GSES Co₂ assessment verification are accessible through your organization’s GSES ESG Scorcard, which is visible to full members.

Audit reports, contextual information, and supporting evidence related to validations and verifications are not shared with third parties, except with auditors from certification bodies.

The costs associated with the ABN AMRO request only cover the audits (validations/verifications). However, you can make use of the outcomes displayed on your GSES ESG Scorecard. Additional functionalities (modules) are available through separate GSES memberships

Click here for an overview of the GSES memberships and available modules.

In the context of compliance, it is highly likely that you are contractually obligated to comply with ABN AMRO’s request. GSES works with various clients, where both mandatory requirements and voluntary requests may apply.

For a first-line validation, the process typically takes 2 business days.

A second-line validation can take up to 10 business days, and a verification generally takes between 10 and 15 business days, provided all information is submitted clearly, timely, and completely.

The EcoVadis certificate relates to a second-line validation, for which additional supporting documents are required. These will be requested after receiving the certificate and report.

ABN AMRO’s CSRD questionnaire and the CO₂ assessment both involve a verification.

• Do you have an EcoVadis certificate?
  Registering and uploading the certificate and audit report typically takes no more than a few minutes.
• ABN AMRO’s CSRD Questionnaire and CO₂ Assessment:
  Filling in the questionnaire and uploading the required evidence usually takes no more than one hour per section, provided all necessary context and documentation are readily available.

If you upload and submit additional certificates for validation to potentially improve your GSES ESG Scorecard, a GSES Limited Membership will be required.

To complete additional assessments, a GSES Pro Membership is required. These assessments can also be submitted for verification to potentially enhance your GSES ESG Scorecard.

The same applies to other modules.
