White Paper: Mastering Carbon Footprint Assessment in Procurement

More and more suppliers are being asked by their customers to report their carbon footprint for the first time—whether in supplier questionnaires, in requests for proposals, or through EcoVadis and CDP. This executive summary condenses the white paper “Getting Started with Carbon Accounting for Suppliers in 2026,” which Five Glaciers Consulting developed in collaboration with ClimateChoice, into five pages—and shows how to get started without feeling overwhelmed.

At a Glance:

• Why Carbon Accounting Is Becoming a Business Necessity —Driven by the Market and, Indirectly, by the CSRD and CBAM
• Fundamentals of a Robust GHG Inventory – The GHG Protocol, the Three Scopes, and the Data Quality Ladder
• Taking a Pragmatic Approach to Scope 3 – Screening and Prioritization Instead of Complete Data Coverage
• A selection of freely available tools for the initial assessment, including the Five Glaciers Carbon Navigator
• Supplier Engagement Blueprint – The Six-Step Approach, from Data Collection to Reduction Strategy

Prepared by Five Glaciers Consulting in collaboration with ClimateChoice. The full white paper is available in English.
