Decarbonising Supply Chains to Reach Net-Zero: Strategies, Tools, and Compliance

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

Collaborative Decarbonization Programs:

• Joint efficiency improvements and renewable energy adoption

• Shared investment in low-carbon technologies

• Product redesign collaboration for reduced environmental impact

• Supplier data gaps: Many businesses rely on estimates rather than accurate supplier data

• Inconsistent methodologies: Different suppliers using varying carbon accounting standards

3. Organizational and Cultural Barriers

Change Management Challenges

Only 5% of supply chain emissions stem from direct manufacturing, whereas emissions from the supply chain can be 5 to 10 times greater, requiring unprecedented cross-organizational collaboration.

Organizational Barriers Include:

• Resistant mindset: Overcoming resistance to change and shifting deeply ingrained behaviors

• Supply chain complexity: Aligning diverse stakeholder interests across global supply networks

• Expertise gaps: Organizations under pressure to decarbonize lack the expertise to do so effectively

4. Capacity and Capability Constraints

Implementation Challenges

Recent surveys show 63% of organizations need help understanding how to apply CSDDD requirements, highlighting widespread capability gaps.

Capacity Constraints:

• Technical expertise shortage: Limited internal capability for carbon accounting and supplier engagement

• Resource allocation: Competing priorities for limited organizational resources

• Supplier readiness: Varying levels of supplier maturity in sustainability practices

CSRD and CSDDD Compliance: Regulatory Drivers for Supply Chain Decarbonization

Corporate Sustainability Reporting Directive (CSRD)

Comprehensive Reporting Requirements

The CSRD mandates detailed sustainability reporting across value chains, with companies required to report on GHG emissions and reduction targets across all three scopes.

Key CSRD Requirements:

Scope 3 Emissions Reporting:

• 80% of typical company carbon footprint stems from value chain, making Scope 3 likely material for most reporters

• Breakdown of emissions by category with measures for 1.5°C-aligned decarbonization pathway

• Limited assurance required starting 2025; Omnibus I removed the planned move to reasonable assurance

Implementation Timeline:

• First wave (2024): Large public-interest entities already under NFRD

• Second wave (2025)**: Large companies, now only those with more than 1,000 employees and over €450M turnover - first reports delayed to 2028, covering FY2027

• Non-EU companies**: Groups with more than €450M of EU turnover and an EU subsidiary or branch above €200M report on FY2028, in 2029

Corporate Sustainability Due Diligence Directive (CSDDD)

Climate Transition Plans

The CSDDD originally required companies to adopt and implement climate transition plans aligned with limiting global warming to 1.5°C, until Omnibus I deleted that obligation in 2026.

Former CSDDD Climate Requirements:

Transition Plan Elements:

• Time-bound targets for 2030 and five-year increments to 2050

• Science-based absolute emissions reduction targets for Scope 1, 2, and 3

• Description of decarbonization levers and investment quantification

Implementation Timeline:

• **Entry into force**: July 25, 2024

• Member state transposition**: By July 2028 (extended from 2026)

• First compliance**: Companies with 5,000+ employees and €1.5B+ turnover from July 2029

Enforcement and Penalties:

• Fines capped at 3% of global net turnover

• Civil liability for affected stakeholders, now left to national law

• Public naming and potential market exclusion

Regulatory Compliance Strategies

Preparing for Dual Compliance

Companies within CSRD scope that report transition plans were deemed compliant with CSDDD transition plan obligations. Omnibus I deleted that CSDDD obligation in 2026, but CSRD still requires companies to disclose a climate transition plan under ESRS E1 if they have one.

Compliance Preparation Steps:

1. Gap Analysis: Assess current sustainability reporting and due diligence practices

2. Supply Chain Mapping: Develop comprehensive visibility beyond Tier 1 suppliers

3. Transition Plan Development: Create science-based, time-bound decarbonization roadmaps

4. Supplier Engagement Programs: Establish systematic supplier assessment and improvement processes
