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. 

The Manufacturer’s Subgroup (SG) consists of GPSNR members who are rubber product manufacturers only.  The SG is seeking a consultant/field to map their supply shed (i.e., all the farms that they are sourcing from) focusing on polygon mapping techniques in complex supply chains such as in Indonesia, Malaysia and Thailand – each with a separate RFP, and report on the price and time required for each polygon mapped.

Objectives

The goal of the project is to investigate what effort (i.e., time and cost) may be required for a rubber processor to map their supply chain in complex supply chains in Malaysia. 

The consultant is to map small holder farmers in selected regions within Malaysia. Manufacturers will specify the regions to be mapped at a later date. 

The service provider should work with the Manufacturer’s Subgroup and the participating processors from Malaysia and their dealers to:

1. Keep track of the time and costs of all mapping related activities throughout the study, calculate time and cost of mapping each polygon, and provide them to their GPSNR Point of Contact at the end of the survey.

2. Register farmers using a provided data logger application. The service provider is welcomed to use their own data logger application. 

Scope of Work/Expected Deliverables

Specifically, GPSNR expects the consultant to:

1. Map regions of rubber producers supplying to the participating processor in Malaysia via polygon mapping. 

   1. Single GPS coordinates should not be utilised irrespective of the size of the plantation. 

   2. Geo mapping to include coordinates up to 6 decimal places in geoJSON format 

2. 2. Store/transfer geo location polygons mapped, to a 3rd party database as designated. 

   3. Bi-weekly progress reports 

   4. Ensure compliance to applicable local and global data privacy norms and regulations such as but not limited to GDPR, PDPA, etc.

2. We would like a detailed account of the resources: 

   1. Price per polygon mapped – Cost per unit (per Farmer/Plot/Polygon) 

   2. Timeline to map Polygons per day (eg 18 months to map X polygons)

3. A recommendation of the scalability of this pilot

   1. Can the same estimated cost/time/labour be replicated in other regions/jurisdictions within the same country?

   2. E.g., $X/farm is calculated but is not scalable due to what reason(s).

4. Interested parties should submit the quote for the following – 

   1. For mapping polygons (cost per Ha)

   2. For mapping polygons + completing set of questionnaires as a part of risk assessment

5. Comply with applicable data privacy norms and regulations (including but not limited to GDPR and PDPA).

6. An optional activity that service providers could provide is the ability to integrate a transactional traceability function (own or 3rd party as designated)

1. A workplan that outlines the key activities towards the deliverables outlined in Expected Deliverables above

2. The timeline and key stages of operations based on Project Timeline below

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.

• Conduct 5-10 office assessments (remote or on-site, as required) to evaluate conformity with GPSNR requirements and the effectiveness of ASP management systems.
• Conduct 5-10 witness assessments by observing ASP assessors or assessor teams during GPSNR field assessments.
• Apply appropriate oversight assessment techniques, including document review, interviews, and witnessing of audit activities.

Assessment Preparation and Planning

• Support GPSNR Secretariat in defining the scope, type, and objectives of oversight assessments.
• Prepare assessment agendas and support logistical planning as required.
• Review background documentation prior to assessments, including previous oversight reports and ASP records.
