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 Capacity Building Working Group: Smallholders GAP Coaching in Indonesia (GPSNR-RFP-A02-017)

  1. INTRODUCTION

The Global Platform for Sustainable Naural Rubber is an international, multi-stakeholder, voluntary membership initiative committed to improving the socioeconomics and environmental performance of the natural rubber value chain.  Development of the GPSNR was intiated 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 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 aims to support the natural rubber sector to become more sustainable. Key element in achieving  this is to ensure there is capacity among smallholders and industrial plantations to adopt best practices in NR  production.

GPSNR, through the GPSNR Capacity Building Working Group (Indonesia National Subgroup), is seeking proposals to disseminate coaching materials and implement coaching on Good Agricultural Practices (GAPs) for smallholders in Indonesia.

Proposed coaching programmes should be implemented in line with GPSNR environmental and social commitments and values, based on the GPSNR Policy Framework[1].

  1. OBJECTIVES AND SCOPE OF WORK

2.1 Context

There are approximately 2.25M smallholders in Indonesia, representing 83% of national natural rubber production (3.6 M tonnes). Smallholders cultivate less than 2 ha of land with an average yield of slightly below 1 ton/ha, as compared to state and private commercial plantations achieving 1.4 ton/ha and 1.5 ton/ha respectively.

Indonesia’s average rubber yield is significantly lower than neighbouring countries in Southeast Asia; such low yield is due to low-quality clones, limited knowledge of Good Agricultural Practices (GAP) and aging trees.

Most rubber trees in Indonesia were planted from 1978-1991 through several government schemes. Given that rubber trees only have a 25-year productive lifespan, with steeply declining yields thereafter, almost all rubber trees planted under these schemes have passed their peak production. Whilst there is no formal data available on tree aging in Indonesia, the Ministry of Agriculture estimates around 600,000 – 700,000 ha of natural rubber plantations need rejuvenation. Replanting should ideally occur on about 4% of plantations annually to ensure a stable output. Yet, it is estimated that between 2010 and 2017 replanting of only 1.3% was undertaken.

Diseases are a major threat to rubber trees, with 80 – 90% of farmers experiencing tree diseases in 2019 in West Kalimantan and South Sumatra, and 60% in Jambi. When disease (pink and white root rot) attacks trees, the trees should be cut down, leaving not even the stem in the ground, to minimise infection of other trees. A new rubber leaf fall disease is spreading in Sumatra and Kalimantan. This disease causes leaf fall more than twice a year and reduces annual yield by up to 40%. The treatment for this disease is expensive and is often not implemented by smallholders.

Land preparation for replanting is also an important factor for sustainability of production and can lead to lower rubber disease infection rates. Young trees are susceptible to numerous diseases and pests, which smallholders must be coached and financially supported to protect in years 1 – 3. The cost of land preparation and field protection is among the most expensive investments, besides the purchase costs of high yielding clones. Costs incurred during the tree replanting stages is around $2,600 per ha over a 5-year period. During the 6th year, the trees will become productive and operational costs will be $460 pa.

Using the right clone makes a tremendous difference in a rubber tree’s lifetime yields. The productivity of rubber clonal and seedling-derived plants is almost 3 x lower than for certified clones. Across the region, only 5% of farmers received their seedlings through a government programme. Certified nurseries are only located in provincial and district capital cities resulting in limited access to high-yielding planting materials for remote smallholders.

Additionally, poor tapping techniques are another major cause of low yields and can decrease the productive life of trees by up to 50%. It is estimated that an average smallholder with 1.5 ha of rubber will earn 57% less than the Indonesian minimum wage.

Smallholders’ rubber plots and jungle rubber, as opposed to large, monoculture commercial estates, demonstrate higher animal diversity and may be able to come closer to mimicking the diversity found in natural forest ecosystems. Yet, low yields and record low international prices are driving smallholders to clear their jungle rubber and convert to other land uses such as palm oil. Research indicates in some villages on average, smallholders now grow rubber on only 0.34 ha with another 2.17 ha devoted to oil palm, and 66% of natural rubber plantations had been converted to oil palm. Cultivating oil palm also has other benefits such as i) being less labour intensive and generally farmers do not need to hire external labour – although gross returns of rubber are higher, the lower labour requirement for oil palm makes it more profitable for smallholders; ii) palm oil farmers receive more support from the government and supply chain actors; iii) contract farming arrangements for palm oil enables farmers to get loans/credits and extensions services from companies; and iv) the longer start up time for new rubber trees compared to oil palm is another factor as farmers receive income earlier than when planting rubber.

Five provinces contribute 66.5% of national production: South Sumatra, North Sumatra, Jambi, Riau, and West Kalimantan. South Sumatra province is Indonesia’s largest and most productive area. Its natural rubber area is almost 23% of the total national productive area and smallholders’ plantations take up 98.5% of this area. The productivity of smallholders in South Sumatra is the highest among smallholder areas in Indonesia, producing 1.3 ton/ha, and more likely to have received GAP training. In 2019 the government announced a replanting plan for 2019 – 2027, with a focus on South Sumatra (92,600 ha), South Kalimantan (76,550 ha) and Jambi (69,900 ha). However, this plan has no large-scale lending programme associated with it and is to be executed by local governments and has not yet been implemented. Demand for replanting is strongest in Jambi, where 40% of farmers are willing to undertake replanting. Demand is lowest in West Kalimantan, where only 1 farmer out of 79 was contemplating. Most likely the demand in Jambi is due to peak planting being undertaken in 1995 – 2005 and the majority of the trees are approaching their maximum productive age, and Jambi farmers are more aware of the importance of good quality clones and their impact on yield – they also have the highest rate of nursery clone purchase – and have suffered less from disease.

(CLOSED) Request for Proposal – GPSNR Baseline reporting requirements pilot

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 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 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 strategy and objectives.

GPSNR’s Policy Toolbox Working Group is developing for approval two key documents that will form GPSNR member requirements. First is a set of Policy Components, which outlines specific commitments that GPSNR company members should include in their sustainable natural rubber policies. Second are the Baseline Reporting Requirements, which indicates qualitative and quantitative sustainability data to be reported to the GPSNR Secretariat for year 1 (2020). To finalize these Baseline Reporting Requirements, the Working Group is conducting a pilot test with volunteer companies. The aim of the pilot is to understand any constraints companies may have in obtaining or sharing certain information, with the goal to refine and finalize the Baseline Reporting Requirements based on company feedback.

In order to achieve this, GPSNR is seeking a fixed term consultancy firm who will be responsible for gathering the responses from pilot participants, ensuring data security and confidentiality, and providing a short aggregated summary of data, including recommendations to GPSNR to inform the revision of the reporting requirements and questionnaire.

Scope of Engagement

The consultancy firm shall provide:

A system to collect data that must:

  1. Provide a secure and unique login for pilot participants to access data submission form  
  2. Ensure data security during transmission and storage of data (as some data will have commercial sensitivity)
  3. Possess, at minimum, the following:
    Ability to export data collected into CSV, XML or PDF formats for data analysis
    Salesforce integration
    Ability to accept file attachments
  4. Allow pilot participants to identify the preferred type of disclosure for each data point, according to the following categories:
    Public Disclosure
    Disclose only to GPSNR Secretariat
    Disclose only to consultant (for aggregate reporting)
