Supply chain emissions represent the overwhelming majority of most organizations' carbon footprints, yet they remain the most challenging to address. Organizations' supply chain emissions are, on average, 11.4 times higher than operational emissions, accounting for approximately 92% of an organization's total carbon footprint. As companies race to meet net-zero commitments by 2030 and 2050, decarbonizing these complex, global value chains has become not just an environmental imperative, but a critical business strategy for regulatory compliance, risk mitigation, and competitive advantage.

This comprehensive guide explores how organizations can effectively measure, reduce, and manage supply chain emissions through strategic supplier engagement, emerging technologies, and compliance with evolving regulations like the CSRD and CSDDD.

Why Supply Chains Represent the Largest Emissions Challenge

The Scale of Scope 3 Emissions

Scope 3 emissions typically represent 70-95% of a company's total carbon footprint, yet they occur outside direct organizational control. These emissions encompass the entire value chain, from raw material extraction and manufacturing to transportation, product use, and end-of-life disposal.

Recent research reveals the scope of this challenge:

• Upstream Scope 3 emissions make up, on average, two-thirds of Scope 3 emissions for consumer goods companies

• Just eight global value chains are collectively responsible for 50% of global emissions

• Around 70% of international trade today involves global value chains (GVCs)

Industry-Specific Emission Patterns

Different industries face unique supply chain decarbonization challenges:

Consumer Goods & Retail:

• Upstream Scope 3 emissions make up two-thirds of total Scope 3 for consumer companies

• Primary drivers include ingredients, packaging materials (paper, plastic, glass), and manufacturing processes

Food & Agriculture:

• Meat and dairy account for almost half of all product-related Scope 3 emissions

• Supply chain interventions can reduce emissions by up to 50% through farm-level improvements

Technology:

• 96% of Microsoft's total emissions come from Scope 3 sources

• Focus areas include manufacturing, packaging, and end-of-life product management

Strategic Approaches to Supply Chain Decarbonization

1. Comprehensive Emissions Mapping and Measurement

Establishing Baseline Data

The foundation of effective supply chain decarbonization begins with comprehensive emissions mapping. According to recent surveys, many businesses rely on estimates rather than accurate supplier data, leading to unreliable reporting and unclear understanding of environmental impact.

Key steps include:

• Scope 3 category analysis: The GHG Protocol defines 15 categories of Scope 3 emissions, though not every category applies to all organizations

• Supplier emissions assessment: Moving from spend-based estimates to primary supplier data

• Hotspot identification: Focusing on suppliers and categories with the highest emissions impact

• Data quality improvement: Transitioning to primary supplier data rather than secondary estimates is critical for improving accuracy

2. Strategic Supplier Engagement Programs

Science-Based Target Setting

Companies must set scope 3 targets that collectively cover at least 67% of total scope 3 emissions if these emissions are significant. Effective supplier engagement targets specify the portion of emissions covered by suppliers setting their own science-based targets.

Successful engagement strategies include:

Tiered Supplier Approach:

• Tier 1 suppliers: Direct engagement on emissions reduction and renewable energy adoption

• Sub-tier visibility: Breaking the barrier of visibility beyond Tier 1 allows organizations to identify new risks and drive ESG goals through better traceability
