How a Global Manufacturer Mapped Scope 3 Emissions Across Their Supply Chain

Overview

A global manufacturer with operations worldwide partnered with Climatise to screen their full Scope 3 footprint and build a roadmap for supply chain decarbonisation.

The challenge

As a global manufacturer sourcing raw materials from complex agricultural supply chains, they faced the challenge of measuring Scope 3 emissions that dwarfed their operational footprint — while navigating multiple reporting frameworks across different jurisdictions.

• Complex global supply chain with raw materials sourced from agricultural producers worldwide • Scope 3 emissions estimated at 80%+ of total footprint, but with limited visibility into actual numbers • Multiple reporting requirements across jurisdictions (UK SECR, EU CSRD preparation) • Manufacturing operations with significant energy consumption and waste streams • Customer demand (major FMCG brands) for supply chain carbon transparency

The solution

Climatise conducted a comprehensive Scope 3 screening, established baselines across all 15 GHG Protocol categories, and prioritised the supply chain categories that mattered most for reduction.

Full Scope 3 Screening: All 15 GHG Protocol Scope 3 categories screened using spend-based analysis, with Category 1 (purchased goods) identified as the dominant source.

Supplier-Specific Data: Key raw material suppliers engaged via automated questionnaires to replace spend-based estimates with primary data for top emission sources.

Multi-Framework Reporting: UK SECR report generated alongside CSRD-aligned data collection for EU operations, using consistent methodology across both frameworks.

Reduction Prioritisation: Data-driven prioritisation of supply chain interventions: renewable energy procurement, logistics optimisation, and supplier engagement for top-20 raw materials.

Impact

• Global Scope 3 screening completed • 15 categories assessed per GHG Protocol • Dual framework compliance (SECR + CSRD) • Top 20 supplier engagement programme launched

Supply chain transparency

• All 15 GHG Protocol Scope 3 categories screened and baselined • Automated supplier questionnaires replacing spend-based estimates with primary data • Dual-framework compliance across UK SECR and EU CSRD • Data-driven prioritisation targeting top-20 raw material suppliers
