Supply Chain Optimization Guide

A comprehensive guide to understanding, measuring, and reducing supply chain emissions while achieving 5-10% cost savings.

Overview

Supply chain emissions, also known as Scope 3 emissions, account for 70-80% of most organizations' total carbon footprint. These are indirect emissions that occur in your value chain, including purchased goods and services, transportation, and end-of-life product treatment.

By optimizing your supply chain, you can achieve significant environmental and financial benefits simultaneously—typically 5-10% reductions in both carbon emissions and operational costs.

Key Statistics

  • • 70-80% of emissions hide in supply chains
  • • 5-10% cost savings potential through optimization
  • • 2-3 year payback period for most initiatives
  • • 15-25% reduction in supply chain emissions is achievable
Understanding Scope 3 Emissions

Scope 3 encompasses all indirect emissions in your value chain. It's divided into 15 categories:

Upstream Emissions (Categories 1-8)

  • • Purchased goods and services
  • • Capital goods
  • • Fuel and energy-related activities
  • • Upstream transportation and distribution
  • • Waste generated in operations
  • • Business travel
  • • Employee commuting
  • • Upstream leased assets

Downstream Emissions (Categories 9-15)

  • • Downstream transportation and distribution
  • • Product use
  • • End-of-life treatment
  • • Downstream leased assets
  • • Franchises
  • • Investments
Assessment Framework

Follow these steps to assess your supply chain emissions:

1

Establish Baseline

Calculate current emissions across all Scope 3 categories relevant to your business

2

Identify Hotspots

Determine which categories and suppliers contribute most to your footprint

3

Engage Suppliers

Collect data from key suppliers on their emissions and practices

4

Set Targets

Define reduction goals aligned with science-based targets

5

Develop Strategy

Create action plans for each high-impact category

Top Optimization Opportunities

Supplier Engagement

Work with top suppliers to reduce their emissions. Often yields 15-20% reductions with minimal cost.

Transportation Optimization

Consolidate shipments, optimize routes, and shift to lower-carbon transportation modes. Saves 10-15% in costs.

Packaging Reduction

Reduce packaging weight and material, use recycled content. Quick wins with immediate cost savings.

Circular Economy

Design for reuse, recycling, and end-of-life recovery. Reduces waste and creates new revenue streams.

Renewable Energy

Transition to renewable energy in operations and encourage suppliers to do the same. Long-term cost benefits.

Implementation Roadmap
