FEBRUARY 2026 

ISSUED BY 
Global Platform for Sustainable Natural Rubber 

Introduction & Background 

The Global Platform for Sustainable Natural Rubber (GPSNR) is an international, multi-stakeholder, voluntary membership initiative seeking to lead improvements in the socioeconomic and environmental performance of the natural rubber value chain. Members of the platform include tire manufacturers, rubber suppliers and processors, vehicle makers and NGOs. Representatives from each of these stakeholder groups have contributed to the development of the Singapore-based platform and the wide-reaching set of priorities that will define strategy and objectives.

The GPSNR Assurance System, designed by Assurance Services International (ASI) and for GPSNR members, is a risk-based framework that supports credible and independent assurance processes. It enables companies to identify and mitigate human rights and environmental risks within their supply chains, undergo third-party verification, and report transparently on their progress through credible claims.

As part of its Assurance System, GPSNR operates an oversight mechanism to ensure that approved Assurance Service Providers (ASPs) deliver assessment and assurance services in conformity with GPSNR requirements. This oversight function is a critical component of maintaining the credibility, consistency, and integrity of the GPSNR Assurance System.

GPSNR is therefore seeking proposals from qualified and experienced individuals or organizations to provide GPSNR Oversight Assessor services in accordance with GPSNR oversight procedures and requirements.

The Engagement 

The GPSNR Secretariat is seeking one or more qualified Oversight Assessors to support GPSNR in planning, conducting, and reporting on oversight assessments of Assurance Service Providers.

(CLOSED) Request for Proposal GPSNR POLICY IMPLEMENTATION GUIDANCE AND REPORTING REQUIREMENTS

Introduction & Background

The Global Platform for Sustainable
Natural Rubber (GPSNR), is an international, multi-Stakeholder, voluntary
membership initiative seeking to lead improvements in the socioeconomic and
environmental performance of the natural rubber value chain. Development of the
GPSNR was initiated by the CEOs of the World Business Council for Sustainable
Development (WBCSD) Tire Industry Project (TIP) in 2018. Members of the
platform include tire manufacturers, rubber suppliers and processors, vehicle
makers, smallholder rubber growers, and NGOs. Representatives from each of
these stakeholder groups have contributed to the development of the
Singapore-based platform and the wide-reaching set of priorities that will
define GPSNR strategies and objectives.

Through a process led by the Policy
Toolbox and Implementation Guidance Working Group (WG1), the General Assembly
approved a Policy Framework in September 2020 that outlines the specific
commitments to sustainable natural rubber that GPSNR company members must
include in their public policies or other relevant documents.  GPSNR ordinary member companies are required
to create new or update existing policies to align with the Policy Framework by
March 2021 (companies will have a possibility to request an extension provided
they can demonstrate progress in developing or updating their policies).

WG1 is finalizing Baseline
Reporting Requirements (BRRs) for ordinary member companies to assess where
they are in their sustainability journey. 
Once WG1 finalizes the BRRs, it will send them to the GPSNR Executive
Committee (EC) for review and approval. 
Company members will be expected to provide the GPSNR Secretariat with
their baseline reporting data in 2021 (date to be confirmed).

The next step is for GPSNR to
develop the Implementation Guidance and future Reporting Requirements
as they pertain to the specific commitments laid out in the GPSNR policy
components.  The Implementation Guidance
and Reporting Requirements will vary depending on where a member company sits
within the natural rubber supply chain, so this work will be organized by the
following stakeholder categories: 
natural rubber producers/processors and traders, tire makers and other
natural rubber product manufacturers, and auto makers and other end users. 

In order to achieve this, the
Platform is seeking a fixed term consultancy to facilitate the development of
the Implementation Guidance and Reporting Requirements for each of the 3
stakeholder categories.  While WG1 will
provide oversight to this process, GPSNR will invite the creation of focus
groups for each of the three stakeholder categories to enable broader participation
of members from each of the stakeholder groups (although focus groups can also
include members from other stakeholder categories).  The consultant first will facilitate the
development of the Implementation Guidance for each of the 3 categories by
reviewing guidance and requirements from other initiatives, such as the
Accountability Framework, as well as certification schemes such as RSPO, FSC,
PEFC, Cocoa Forests Initiative, and others to prepare draft guidance.  The consultant will gather input from the WG1
Co-chairs and the GPSNR Secretariat on the draft, and will then facilitate
various rounds of discussion with the focus groups to finalize the guidance for
each stakeholder category.   All comments
will be recorded in a spreadsheet and the decision-making process for
incorporating or rejecting comments will be clearly documented.  The Implementation Guidance will include a
corresponding Action Plan template for companies to submit to GPSNR on an
annual basis to indicate which activities they intend to focus on in the coming
year.

Once the focus groups have agreed on the language for the Implementation Guidance and the Action Plan template, they will be submitted to the broader WG for approval.   Meanwhile, the Consultant will develop the Reporting Requirements for each stakeholder category.  The Reporting Requirements will build off of the BRRs and will align with the Implementation Guidance.  The consultant will also review other reporting schemes that members report into, such as ZSL Spott, Global Reporting Initiatives, CDP Forests, and Ecovadis to identify where GPSNR requirements are similar and to align wherever possible.  The Consultant will work with the appropriate focus groups to further design the Reporting Requirements for each stakeholder category.  Once approved by the focus groups, the Reporting Requirements will go to the broader WG1 for approval, and then on to the EC.

(Closed) Request For Proposal – GPSNR-RFP-A02-019 Guidance and Tools for GPSNR’s Reporting Requirements

Introduction & Background

The Global Platform for Sustainable Natural Rubber (GPSNR) is an international multi-stakeholder, voluntary membership initiative seeking to lead improvements in the socioeconomic and environmental performance of the natural rubber value chain. Members of the platform include tire manufacturers, rubber producers and processors, vehicle makers and NGOs.

In December 2021, GPSNR members approved Reporting Requirements that would allow member companies to report on their progress implementing their commitments under the Policy Framework. With the approval of the reporting requirements, ordinary member companies shall report annually on the questions included in the Reporting Requirements for the member’s reporting category.

GPSNR members are required to submit data for the previous year according to the following reporting timelines:
• Category A and Category B: Industrial Producers or Processors and Traders of Raw Materials: on or before 30 June
• Category C: Manufacturers and Traders of Processed Material: on or before 30 September
• Category D: OEMs and End Users: on or before 31 December.

To support GPSNR members in fulfilling their obligations under the Reporting Requirements, the platform is calling for consultants to develop a systemic view of the reporting process, inclusive of developing supporting documents and reporting templates for members to facilitate reporting, and exploring the potential user interface and portal design for data submission to ease the integration and consolidation of reported information from various GPSNR member categories.

Reporting scope and materiality are topics for consultant’s review and suggestion based on the GPSNR reporting requirement.

The reporting process should cover the following scenarios (non-exhaustive list):
(i) tier-1 supplier is disclosed to GPSNR
(ii) tier-1 supplier is not disclosed to GPSNR
(iii) members with suppliers across different category groups that are not GPSNR members
(iv) members with external reports that may substantiate the GPSNR reporting requirement
(v) how the information is consolidated at GPSNR level at the end of each category reporting cycle

Figure below is taking one example of tire maker category member reporting on NR supply chain scope to illustrate the potential complexity of the reporting process.

The expected documents to be developed should include:

  • A guidance document for each reporting category outlining the appropriate methodology and reporting format for each question, with reference to necessary definitions. One example of reporting segment that requires guidance is Policy Component 2.5 and 2.6 for member categories C and D.
  • Standardized reporting templates which may utilize word documents, excel spreadsheets, or other appropriate reporting formats.

The documents developed should ensure that data can be consolidated easily across the supply chain with an understanding that the information will be passed downstream. Where appropriate, the requested data should align with data gathered by other reporting schemes to reduce the reporting burden (including, but not limited to, CDP, Ecovadis, ZSL SPOTT, GRI, FSC, PEFC, SNR-i).

The reporting user interface which includes ability for member to upload supporting evidence (e.g., documents, photos etc) and portal design should also enable easy intake by the Secretariat for data analysis, verification and reporting. The ability to design integration with Salesforce is a plus.

Submission Guidelines & Requirements

The following submission guidelines & requirements apply to this Request for Proposal:

  1. Proposals will only be accepted from individuals or firms with experience relevant to this project.
  2. Examples of previous relevant work should be provided as well.
  3. A technical proposal must be provided that should be around 6 pages in length. This technical proposal must provide an overview of the proposed methodology as well as resumes of all key personnel performing the work. In addition, the technical proposal should provide a proposed schedule and milestones, as applicable.
  4. A price proposal must be provided that is not more than 1 page. This price proposal should indicate the overall fixed price for the project as well as daily rates and an estimated total number of days.
  5. Proposals must be signed by a representative that is authorized to commit bidder’s company.
  6. Proposals must be received prior to 14th of March to be considered. Proposals should be submitted to stefano.savi@gpsnr.org and aidan@gpsnr.org for consideration.
  7. GPSNR anticipates shortlisting at least two individuals or firms to have more in-depth discussions with, and will make an award to one of these “down-selected” individuals or firms.
