Bosch Scales CDP Supplier Engagement to Over 4,500 Companies by 2025

Bosch Group has expanded its CDP-linked supplier engagement programme from 500 suppliers in 2021 to over 4,500 in 2025, with more than 3,200 currently disclosing environmental data. The German industrial conglomerate is using this primary data to inform procurement decisions, create internal supplier scores, and support its target to reduce Scope 3 emissions by 30% by 2030 relative to 2018 levels.

Bosch's Scope 3 supply chain emissions are on average 26 times greater than its operational emissions, making supplier engagement central to its decarbonisation strategy. The company works with CDP's Supply Chain Membership programme to collect primary CO2 data, which it integrates into internal supplier scorecards alongside CDP's climate scoring. This data-driven approach informs Bosch's purchasing process through incentive programmes and performance expectations, and has contributed to measurable emission reductions among multi-year disclosing suppliers.

More than 1,270 Bosch suppliers committed to Science Based Targets initiative (SBTi) CO2 targets in 2024, representing over 38% of the company's purchasing volume. This gives Bosch a multiplier effect beyond its own supply chain, as each supplier's commitment cascades through their own value chains. More than half of Bosch's disclosing suppliers are small-to-medium businesses, reflecting the company's effort to reduce barriers for SMEs through CDP's dedicated SME questionnaire and enhanced guidance.

Bosch's CDP-linked supplier data now covers approximately 77% of the company's purchasing volume for primary CO2 data, providing sector-specific insights for strategic procurement decisions. The company plans to continue scaling supplier engagement and education, while leveraging bonus and penalty programmes to incentivise performance improvements. The Bosch approach is increasingly cited as a replicable model for large industrial companies seeking to achieve their Scope 3 reduction targets through structured supplier disclosure and collaboration.
