This extension provides a detailed breakdown of greenhouse gas emissions according to the GHG Protocol’s three scope categories, enabling comprehensive carbon accounting and reporting.

Purpose

The Emissions Scope Breakdown Extension enables:

  • GHG Protocol compliance: Align with international greenhouse gas accounting standards
  • Comprehensive carbon accounting: Track emissions across all operational boundaries
  • Supply chain transparency: Distinguish between direct and indirect emissions
  • Strategic planning: Identify emission reduction opportunities by scope
  • Regulatory reporting: Meet scope-specific reporting requirements

Use Cases

  • Carbon footprint reporting: Provide detailed scope-based emission breakdowns
  • Supply chain management: Analyze upstream and downstream emission impacts
  • Energy strategy: Identify opportunities for renewable energy procurement (Scope 2)
  • Vendor assessment: Evaluate supplier emissions (Scope 3)
  • Carbon reduction planning: Prioritize reduction efforts by scope and impact

Integration with Core PACT

This extension should complement the core PACT emission values:

  • The sum of Scope 1, 2, and 3 should align with total PCF values
  • Particularly relevant for fossilGhgEmissions breakdown
  • Supports transparency in emission boundary definitions
  • Enhances understanding of emission sources and hotspots

Scope Definitions (GHG Protocol)

Scope 1: Direct Emissions

  • Stationary combustion: Fuel burned in boilers, furnaces, turbines
  • Mobile combustion: Fuel burned in company vehicles, ships, aircraft
  • Process emissions: Chemical reactions, fugitive emissions
  • Fugitive emissions: Refrigerants, natural gas leaks

Scope 2: Indirect Energy Emissions

  • Purchased electricity: Grid electricity consumption
  • Purchased steam: Steam purchased from external sources
  • Purchased heating/cooling: District heating and cooling systems

Scope 3: Other Indirect Emissions

  • Category 1: Purchased goods and services
  • Category 2: Capital goods
  • Category 3: Fuel and energy-related activities
  • Category 4: Upstream transportation and distribution
  • Category 5: Waste generated in operations
  • Category 6: Business travel
  • Category 7: Employee commuting
  • Category 8: Upstream leased assets
  • Category 9: Downstream transportation and distribution
  • Category 10: Processing of sold products
  • Category 11: Use of sold products
  • Category 12: End-of-life treatment of sold products
  • Category 13: Downstream leased assets
  • Category 14: Franchises
  • Category 15: Investments

Validation Rules

  • All numeric values must match the PositiveOrZeroDecimal pattern: ^[+]?\\d+(\\.\\d+)?$
  • Values must be zero or positive
  • All properties are optional
  • Description should provide clear methodology context

Best Practices

  • Methodology transparency: Use the description field to explain calculation methods
  • Boundary consistency: Ensure scope boundaries align with organizational boundaries
  • Unit consistency Values should be expressed in a unit consistent with the base PCF unit (typically kg CO2 equivalent)
  • Data quality: Document any estimates or assumptions used
  • Completeness: Strive for comprehensive Scope 3 category coverage
  • Double counting: Avoid double counting between scopes
