Why steel and iron matter for Scope 3
Steel and iron are embedded in vehicles, buildings, infrastructure, machinery, renewable energy systems, appliances, electronics, and capital goods.
For many companies, metals are a major part of upstream Scope 3 exposure, even when they do not buy raw steel or iron directly.
Where steel and iron EACs may be relevant
| Use case | Buyer motivation |
|---|---|
| Automotive supply chains | Support lower-carbon metals embedded in vehicles and components. |
| Data center and infrastructure construction | Address emissions tied to steel-intensive capital projects. |
| Manufacturing and equipment | Support lower-carbon production connected to capital goods and purchased products. |
| Renewable energy deployment | Reduce the embedded emissions of clean energy infrastructure. |
How a steel or iron EAC works
A producer generates eligible lower-carbon steel, iron, or related metal output. A certificate is issued to represent the environmental attribute associated with that production.
A buyer purchases and retires the certificate to support lower-carbon production in a relevant metals market, with documentation of issuance, transfer, and retirement.
