Greenhouse Gas Protocol
The World Resources Institute/World Council for Sustainable Business Development-backed GHG Protocol defines three initial phases for which material and product suppliers, processors or manufacturers report carbon dioxide loads:
• Scope 1 Direct GHG Emissions
• Scope 2 Electricity Indirect Emissions
• Scope 3 Other Indirect Emissions
The GHG Protocol Corporate Accounting and Reporting Standard CO2 emissions parameters run in tandem with Global Warming Potential metrics in Environmental Product Declarations.
