CIPS Sustainability Index

Benchmark your suppliers’ organisational sustainability with
CIPS Sustainability Index (CSI)
– the independent, cross-sector financial, social and environmental supplier audit

Developed by procurement experts, CSI offers a comprehensive, simple, fast and cost-effective online assessment of environmental, economic and social sustainability. Currently available in the UK and Ireland but with plans to go global, it is the only independent, verified measurement tool available, allowing suppliers to prove their sustainability credentials and buyers to obtain essential sustainability information in a more efficient way than via individual and lengthy questionnaires.

  • As a buyer, CSI gives you a better view of your supply chain and reduces your supplier risk
  • As a supplier, CSI helps you to demonstrate excellence in sustainability to industry-approved levels, strengthening information sharing with your customers and supporting your new business bids

    Working in close collaboration with buyers and suppliers, we have developed the CIPS Sustainability Index (CSI) as a platform to accurately measure or demonstrate the sustainability practices of suppliers. 

    Designed to reduce internal buyer processes, CSI replaces lengthy questionnaires with tailored and relevant online questions. Moving the focus from environmental sustainability to include economic and social pillars offers you a detailed, rounded view of your suppliers. In turn, this will allow you as a buying organisation to identify any required improvements in these sustainability credentials and extend your supplier database. Once you have registered, our CSI team will work with you to develop a programme which exactly suits your needs.

    Suppliers who frequently receive questionnaires from buyers will speed up their processes considerably by using the standard, consistent set of questions posed by the CIPS Sustainability Index. After registering your company information, you can complete your tailored questionnaire at leisure, which will be reviewed and scored by our team of experts. From here, they’ll give you your fully accredited score, which you can then share with your buyers or potential buyers via our online portal.

    Benefits - Supplier

    Cost effective: Completing the CSI independent assessment just once, for one fee, is more efficient than completing individual questionnaires from buyers which often ask common questions. The CSI score and detail can be provided to all your customers, saving you time and money.

    Relevance: The CIPS Sustainability Index questionnaire is customised and tailored according to an organisation’s size and sector.

    Access: Individual user accounts offer increased personal service, with dedicated customer support on hand.

    Expertise: A highly trained, specialist evaluation team calculates the final score of each supplier, offering independent recognition of sustainability to each organisation indexed.

    Feedback: Insightful analytics, scorecards and benchmarks specific to each organisation’s size and sector ensure feedback that’s easy to understand and interpret.

    Approval: Proof of benchmarking comes in the shape of the CIPS Sustainability Index rating and certification badge.

    Support: Best practice guidance will help suppliers to enhance their offering and keep abreast of current industry requirements.

Examples include FIFA’s announcement that they have added human rights and sustainability standards into the contracts associated with staging the World Cup.
