The ratio compares sustainable resources to total resources required ('taken in') to operate a supply chain and resources required for related overhead. All processes in a supply chain may require resources. For example: energy resources are required to ship finished goods through the distribution network and to climate control warehouses. Packaging materials are required to ship to end-customers, etcetera.
Intake resources include, but are not limited to:
| Materials
|
Energy
|
Services
|
- Raw materials
- Packaging materials
- Catalysts
- Water
|
- Wind/Solar/Hydro
- Waste
- Electricity
- Natural Gas/Oil
- Coal
|
- 3PM Manufacturing
- 3PL Logistics
- Call Center
|
The sustainability ratio of services acquired may need to be provided by individual service providers. Consider including this data requirement in (future revisions of) service contracts.

Importance
Any supply chain requires resources to operate. A higher ratio of sustainable resources indicates that a supply chain utilizes a higher portion of renewable resources, thus reducing the risk of resource depletion.
Notes
- All supply chains typically have intake of energy, materials, and services, but not always (industrial) water. If no (significant) water intake occurs then use: SWI = 0 and n = 3.
- Intake Sustainability Ratio is calculated by consolidation of direct (supply chain) and indirect (related overhead) processes.
