Scope 1 emissions come from sources a company owns or controls. Scope 2 emissions come from purchased electricity, steam, heat, and cooling. Scope 3 emissions come from other indirect value-chain activities such as suppliers, transport, product use, and end-of-life treatment.
The scopes separate direct operations, purchased energy, and value-chain activity.
Scope 1 is direct. Examples can include fuel burned in company-owned equipment, vehicles, boilers, or industrial processes.
Scope 2 is purchased energy. This is the category most closely connected to renewable electricity certificates because market-based reporting may use qualifying certificates to document purchased renewable electricity.
Scope 3 is broader value-chain activity. GreenPowerHub can support parts of a Scope 3 program when supplier electricity action requires certificate market coverage, RFQs, and documentation.
What to check next
- Use Scope 1 for direct owned or controlled sources.
- Use Scope 2 for purchased electricity, steam, heat, and cooling.
- Use Scope 3 for other upstream and downstream value-chain emissions.
- Use certificate workflows mainly for renewable electricity questions, not every emissions category.
