Scope 3 emissions – particularly from purchased goods and services, but also from transport and the use of sold products – account for a large share of the total CO₂ footprint of most organisations. Yet reducing scope 3 emissions is impossible without the cooperation of suppliers. They generate the emissions, hold the data and must implement the reduction measures.

‍

Structural collaboration – in which suppliers measure, understand and reduce their own emissions – is needed to achieve a lasting reduction in scope 3 emissions. It also strengthens supplier relationships and improves data quality for CSRD and SBTi.

Supplier engagement on CO₂ is a structured programme. We work in three phases – from insight through activation to embedding.

‍

• Prioritisation and supply chain analysis – We map which suppliers and procurement categories contribute most to your scope 3 emissions. Based on emissions volume, strategic importance and engagement potential, we determine where action is most worthwhile.
• Supplier activation and footprint measurement – We guide selected suppliers through mapping their own CO₂ footprint. This shifts you from generic spend-based estimates to primary, supplier-specific emissions data that significantly improve the quality of your scope 3 reporting.
• Shared reduction targets and supply chain collaboration – We help you formulate reduction targets and plans together with suppliers, aligned with your scope 3 ambitions and the capabilities of each supplier. We build a durable engagement structure, including CO₂ criteria in procurement processes and progress monitoring.

Supplier engagement rarely stands alone. These are the logical complementary steps:

• CO₂ footprinting (CCF) – An accurate basis for scope 3 insight and prioritisation of supplier engagement.
• CO₂ target setting and SBTi – Supplier engagement as part of a broader scope 3 reduction pathway towards SBTi validation.
• Decarbonisation roadmap – Shared reduction targets with suppliers as partners for successful decarbonisation.
• Product carbon footprint – Primary supplier data as a building block for accurate PCF calculations.
