Supply Chain Management (SCM) 101: Reverse Logistics and Sustainability - Carbon Footprint in Logistics, Green Logistics Modal Shift Route Optimisation

What This Is

Carbon footprint in logistics, also known as green logistics or sustainable supply chain management, refers to the measurement and reduction of greenhouse gas emissions and other environmental impacts associated with the movement of goods and services. This matters in supply chain management as companies face increasing pressure from customers, investors, and governments to reduce their environmental footprint. For example, Amazon has set a goal to power 50% of its facilities with renewable energy by 2025, reducing its carbon footprint and improving its brand reputation.

Key Frameworks & Formulas

• Carbon Footprint: The total amount of greenhouse gas emissions associated with a product, service, or supply chain.
• Modal Shift: The process of switching from one mode of transportation to another, such as from truck to rail or sea, to reduce emissions and costs.
• Route Optimization: The process of finding the most efficient route for a shipment to reduce fuel consumption, emissions, and costs.
• SCOR (Supply Chain Operations Reference) Model: A framework for evaluating and improving supply chain performance, including environmental sustainability.
• Fisher's Model: A framework for evaluating the environmental impact of supply chain decisions, including transportation and inventory management.
• Emissions Intensity: The amount of greenhouse gas emissions per unit of production or transportation (e.g., kg CO2e per ton-mile).
• Carbon Pricing: A system for charging companies for their greenhouse gas emissions, such as through a carbon tax or cap-and-trade program.
• Life Cycle Assessment (LCA): A method for evaluating the environmental impacts of a product or service throughout its entire life cycle, from raw materials to end-of-life disposal or recycling.
• Greenhouse Gas Protocol: A framework for measuring and reporting greenhouse gas emissions, including those associated with supply chain activities.
• Transportation Emissions Factor (TEF): A measure of the amount of greenhouse gas emissions per unit of transportation (e.g., kg CO2e per ton-mile).

Step-by-Step Application

1. Conduct a Carbon Footprint Analysis: Use a life cycle assessment (LCA) tool or a carbon footprint calculator to measure the greenhouse gas emissions associated with your supply chain.
2. Identify Opportunities for Modal Shift: Analyze your transportation network to identify opportunities to switch from one mode of transportation to another, such as from truck to rail or sea.
3. Implement Route Optimization: Use a transportation management system (TMS) or a route optimization tool to find the most efficient route for your shipments.
4. Set Carbon Reduction Targets: Establish specific, measurable, achievable, relevant, and time-bound (SMART) targets for reducing your carbon footprint.
5. Develop a Sustainability Strategy: Create a comprehensive sustainability strategy that includes goals, objectives, and metrics for measuring progress.

Common Mistakes

• Mistake: Assuming that carbon footprint reduction is only a cost savings initiative.
• Correction: Carbon footprint reduction is a business imperative that can improve brand reputation, reduce regulatory risk, and increase customer loyalty.
• Mistake: Focusing solely on transportation emissions without considering other supply chain activities, such as inventory management and packaging.
• Correction: A comprehensive carbon footprint analysis should consider all supply chain activities, not just transportation.
• Mistake: Not engaging stakeholders, including customers, employees, and suppliers, in the carbon footprint reduction effort.
• Correction: Stakeholder engagement is critical to ensuring that carbon footprint reduction efforts are effective and sustainable.

Exam / Certification Tips

• Be prepared to calculate emissions intensity and carbon footprint: Use the formulas and frameworks provided to calculate emissions intensity and carbon footprint.
• Understand the differences between push and pull strategies: Push strategies involve producing and shipping products in advance of demand, while pull strategies involve producing and shipping products in response to demand.
• Know the Incoterms: Incoterms (International Commercial Terms) define the responsibilities of buyers and sellers in international trade, including the transfer of risk and ownership.

Quick Practice Problem

A company ships 100,000 pounds of goods from Los Angeles to New York via truck. The transportation emissions factor (TEF) for truck transportation is 0.25 kg CO2e per ton-mile. What is the estimated carbon footprint of this shipment?

Answer: 12,500 kg CO2e (100,000 pounds / 2,000 pounds per ton x 0.25 kg CO2e per ton-mile x 2,500 miles)

Explanation: This calculation assumes a transportation emissions factor of 0.25 kg CO2e per ton-mile and a distance of 2,500 miles.
