Carbon footprint
A carbon footprint measures the total greenhouse gas emissions caused directly and indirectly by a product, organization, or activity. In procurement, supply chain emissions (Scope 3) often represent 70-90% of a company's total carbon footprint.
Examples
Supplier emissions tracking: A company requires key suppliers to report annual carbon emissions data, using it to calculate the Scope 3 footprint and identify high-emission categories where reduction efforts would have the greatest impact.
Low-carbon sourcing: When evaluating packaging suppliers, procurement includes carbon intensity as a criterion. A supplier using renewable energy scores higher despite a modest price premium.
Transport mode optimization: Analysis reveals airfreight for non-urgent shipments generates 50x the emissions of ocean freight. Procurement adjusts lead times to shift volume to lower-carbon transport modes.
Definition
For most companies, the supply chain accounts for far more emissions than direct operations. Scope 3 emissions from purchased goods, logistics, and services frequently represent 70-90% of total carbon footprint, making procurement a critical lever for climate goals.
Measuring supply chain carbon is challenging because it requires data from suppliers across multiple tiers. Approaches range from spend-based estimates to supplier-specific primary data, with accuracy improving as organizations move toward actual measured data.
Procurement can reduce carbon through supplier selection, specification changes (lower embodied carbon materials), logistics optimization, and supplier engagement programs that support emissions reduction across the supply base.
Regulatory requirements for carbon disclosure are expanding globally. Procurement teams increasingly need to treat carbon as they would cost—measuring, managing, and reducing it systematically.
Frequently asked questions
What is a carbon footprint?
A carbon footprint measures the total greenhouse gas emissions caused directly and indirectly by a product, organization, or activity. For most companies the supply chain accounts for far more emissions than direct operations, with Scope 3 emissions from purchased goods, logistics, and services frequently representing 70 to 90% of the total.
Why is procurement central to reducing a carbon footprint?
Supply chain emissions frequently represent 70 to 90% of a company's carbon footprint, which makes procurement the largest lever for climate goals. Reduction options include supplier selection, specification changes toward lower embodied carbon materials, logistics optimization, and supplier engagement programs that support emissions reduction across the supply base.
How do you measure supply chain carbon?
Measuring supply chain carbon is challenging because it requires data from suppliers across multiple tiers. Approaches range from spend-based estimates to supplier-specific primary data, with accuracy improving as organizations move toward actual measured data. Many companies require key suppliers to report annual emissions data to build the Scope 3 picture and find the high-emission categories.
How does transport mode affect a carbon footprint?
Airfreight for non-urgent shipments can generate 50 times the emissions of ocean freight for the same goods. Adjusting lead times so volume can shift to lower-carbon transport modes is one of the more direct footprint reductions available to procurement.
Are companies required to report their carbon footprint?
Regulatory requirements for carbon disclosure are expanding globally. Procurement teams increasingly need to treat carbon the way they treat cost, meaning measured, managed, and reduced systematically, and carbon intensity is starting to appear as a criterion in supplier evaluations alongside price.
