Shared Investment Mechanism

Important:
The SIM Workplan and Calendar for 2026 is available here.


Call for Project Proposals — GPSNR Shared Investment Mechanism (SIM) 2027 Funding Cycle is open from 21 April – 15 June 2026. Details here.

The Shared Investment Mechanism (SIM) is a joint-funding framework under which GPSNR ordinary members co-fund in sustainability and capacity-building projects across the natural rubber value chain. The SIM currently applies as a membership requirement for manufacturer members, with opportunities for other member categories to participate.

How members participate
Members meet their SIM commitment in one of two ways:

  • Cash contribution — The member contributes cash to the SIM to co-fund projects collectively with other members.
  • In-kind contribution (IKC) — The member funds their own project that meets the SIM funding principles, in place of contributing cash.

What the SIM funds

  • GPSNR Projects — Initiatives co-funded by members’ cash contributions, selected through open calls for proposals and approved by the Project Management Working Group evaluators and Shared Investment Panel.
  • In-kind contribution projects — Projects initiated and funded by individual member (or with other member/non-member) that meet the SIM funding principles. The member may manage and monitor the project themselves, or assign management and monitoring to GPSNR.

 

All SIM projects (GPSNR-funded or in-kind) must:

  • meet the open-market criteria, meaning they should deliver benefits that can be captured by the entire natural rubber supply chain
  • Align with the GPSNR Policy Framework
  • address social, environmental, and/or livelihood improvements in the natural rubber supply chains, and 
  • address at least one, and ideally two, of the following topics:

a) Smallholder capacity building;

b) Environmental and/or pesticide management;

c) Deforestation

d) HCV degradation;

e) Regulatory and/or legal compliance;

f) Agroforestry;

g) Farm mapping/traceability;

h) HCV/HCS mapping of landscape, community or individual smallholders or group of smallholders;

i) Forest preservation, protection and/or restoration;

j) Diversification of revenues for smallholders;

k) Promoting or enhancing Social and Human Rights; or

l) Tackle barriers to achieving sustainable production, and can be beyond production practice; for example, efforts to ensure smallholders are incentivised towards sustainable production.

Fair contribution formula: Members contribute based on a mix of equal share and their natural rubber sourcing volume. For year 2025/2026, the formula used is: USD25,000 + USD0.4/MT x NR volume sourced by Manufacturer.

Governance and Transparency

  • – The SIM Framework defines how funds are pledged, used, and managed—ensuring full transparency and accountability.
  • – Shared Investment Panel ensures responsibility, accountability, integrity, transparency, compliance, and fairness in decisions relating to the utilization and/or management of funds pledged to the Shared Investment Mechanism.
  • – The Project Management Working Group (PMWG) evaluates project proposals and in-kind contributions for technical soundness and alignment with SIM funding principles. It monitors implementation and reports progress and recommendations to the SIP for review and decision-making.
