Scope 3 is a supply chain problem, not just a supplier problem
Many companies approach Scope 3 by asking direct suppliers to measure, report, and reduce emissions. That is a necessary step, but it is rarely sufficient.
The emissions embedded in purchased goods often originate far upstream in commodity production: the fertilizer used to grow crops, the cement used in buildings, the steel used in equipment, the copper used in electronics, and the freight used to move products.
Where Scope 3 emissions often hide
| Downstream buyer | Visible supplier | Upstream emissions source |
|---|---|---|
| Food and beverage company | Grower, processor, or ingredient supplier | Fertilizer and ammonia production |
| Technology company | Construction contractor or hardware supplier | Cement, concrete, steel, and copper production |
| Retailer | Product manufacturer or logistics provider | Plastics, freight, textiles, and commodity inputs |
| Automotive company | Component manufacturer | Steel, aluminum, copper, plastics, and freight |
Supplier engagement still matters
This is not an argument against supplier engagement. Direct suppliers are important partners. They control data, procurement choices, and operational decisions.
But supplier engagement needs to be complemented by market mechanisms that can reach the upstream commodity systems where decarbonization must occur.
Commodity EACs as a bridge
Commodity EACs can help create that bridge. Instead of waiting for every upstream supplier relationship to be mapped, negotiated, and transformed, buyers can support verified lower-carbon production through certificates tied to specific commodity markets.
