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. The details of which can be found at this link.

The GPSNR Secretariat is seeking qualified organizations and individual professionals to become GPSNR Assessment Service Providers (ASPs). Approved ASPs will conduct impartial and independent third-party assessments in accordance with GPSNR’s procedures and requirements. 

Selected ASPs will be responsible for delivering independent assurance assessments for GPSNR member companies, following GPSNR’s approved Assurance System methodologies and procedures. The engagement includes participation in GPSNR training and oversight processes, adherence to the GPSNR Assurance Service Provider Agreement, and maintenance of competence and impartiality throughout the duration of approval. 

Training for pre-approved ASPs is expected to commence in the first quarter of 2026, with assessments scheduled to begin thereafter upon completion of training and formal approval.

GPSNR Working Groups Update: December 2022

Strategy and Objectives Working Group

The risk subgroup, which sits under the umbrella of this working group, is working on a series of Traceability tools webinars for GPSNR members to present on some tools available that would help members map their supply chain. The subgroup is also working on a pilot traceability study to investigate what it takes (costs, time, labour) for a company to map its supply shed. The subgroup is also working with a consortium to develop a risk assessment matrix.

The assurance model subgroup continues to work on the KPIs set during the last in-person meeting as they are to be finalised at the end of the year and presented during the next in-person and hybrid meetings in January 2023.

Smallholder Representation Working Group

After completing two rounds of pilot agroforestry workshops for smallholder members in Indonesia, and Cambodia, the working group is working on concluding how GPSNR should approach agroforestry capacity building in the long term through an agroforestry strategy. This work stream aims to integrate priorities of smallholders with developing long-term income diversification strategies through the Capacity Building Working Group.

They are also busy holding focus group discussions towards the smallholder policy equivalent, kickstarting HCSA-HCVN programme field trials for natural rubber smallholders, and on enhancing integration with the capacity building working group.

Policy Toolbox Working Group

The group is working on finalizing the TORs for the Year 1 Reporting Review to be conducted in the first quarter of next year. They are also assessing if any changes to the reporting framework and its details (i.e. process, extensions, questions) are needed based on the Year 1 Reporting Review results. They have already kicked off the crosswalk of the reporting requirements against other reporting frameworks to better improve the questions. The group would also be sending out a survey for members to provide feedback on their reporting (reporting process, reporting requirements questions, guidances, etc.). They would also be working on the Transparency Reporting Roadmap for years 2 and 3 of reporting that would be voted at the GA 2023.

Shared Responsibility Working Group

The group is currently evaluating proposals to appoint a software developer for the second phase of the GPSNR Knowledge Sharing Platform based on a reworked tender. In 2022, they have also kicked off the Disease Fighting Project with SNV-IRRI in Indonesia, after having recently completed the first milestones of the Koltiva and SNV-Proforest GAP coaching projects in the country. They continue to seek members’ funding for capacity building projects in Indonesia (second stream of disease fighting) and Cote d’Ivoire (training centres).
