The standard Scope 3 playbook says: trace your supply chain
The default advice for Scope 3 action is to map the supply chain. Identify suppliers. Gather data. Ask for targets. Track progress. Push requirements upstream.
That sounds logical, and it is useful to a point. But in practice, it can become a never-ending search through an upstream maze.
There is another way to look at the problem
Instead of chasing every supplier, follow the commodities.
Many emissions embedded in corporate value chains are tied to a concentrated set of high-intensity industrial inputs: steel, cement, ammonia, chemicals, mining, agriculture, transport, plastics, and other foundational materials.
From supplier mapping to commodity targeting
| Old approach | Commodity-focused approach |
|---|---|
| Map every supplier relationship. | Identify the high-emitting commodity systems embedded in the value chain. |
| Wait for direct suppliers to influence upstream producers. | Create demand signals for lower-carbon production in upstream commodity markets. |
| Treat Scope 3 as a company-specific accounting maze. | Treat Scope 3 as a market transformation challenge. |
| Prioritize visibility before action. | Act where emissions concentration and production pathways are already clear. |
| Focus on one corporate inventory at a time. | Aggregate demand across companies with shared exposure to the same commodity systems. |
Examples of commodity-focused Scope 3 action
A food company may not directly purchase ammonia or fertilizer, but it can still support lower-carbon fertilizer production because fertilizer is embedded in agricultural supply chains.
A technology company may not directly buy cement or copper from the primary producer, but its data centers, hardware, and infrastructure depend on those materials.
A retailer may not control every freight lane or packaging input, but it can still identify logistics and plastics as material Scope 3 systems that need decarbonization.
How commodity EACs make this actionable
Commodity Environmental Attribute Certificates provide a way to connect corporate climate demand with verified low-carbon production in the commodity systems that matter most.
Rather than waiting for perfect supply chain traceability, buyers can support verified lower-carbon production through certificates that are issued, transferred, retired, and documented.
