(CLOSED) Request for Proposal – Study on Living Income Gap in Global Natural Rubber Value Chains – Ivory Coast

Share This Post

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 November 2017. 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.

Through a process led by the Equity Working Group, the Platform has begun an investigation into how value can be equitably distributed across the entire natural rubber value chain. To achieve this aim, it is important for the Platform to gather information about the following metrics in different countries:

i) the prevailing net household income of rubber smallholders;

ii) the detailed cost of production for rubber (input costs, labor etc);

iii) the living income for rubber smallholders;

iv) the living income gap and v) the living income reference price for rubber (the price at which the living income benchmark can be reached).

The Platform has decided to limit the focus of this initial study to Ivory Coast, Indonesia, Thailand, and Myanmar and the consultant is expected to collect information on the aforementioned metrics in Ivory Coast for this study.

Given that living income data is not readily available for each country, alternative benchmarks should be used where relevant and applicable. A list of potential benchmarks and preliminary data are illustrated in the attached document. To facilitate cross-country comparisons of income data and living income levels, the consultant is expected to use consistent units of measurement (per household / per workforce / per person) throughout this study.

The consultant will collect the information via desktop study, interviewing of GPSNR members, research institutes, social NGOs, governmental organizations, etc.  A primary list of stakeholders will be provided by the Secretariat together with the Equity Working Group members.  A complementary list will be developed by the consultant.  Regular contact and updating to the Equity Working Group together with the Secretariat will be required. Travel plans shall be made by the consultant where possible and necessary.

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 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.

Reporting and Follow-up

  • Prepare clear, accurate, and well-justified oversight assessment reports.
