• Employee commuting survey design addresses sampling, remote work and commuting modes
• Homeworking emissions treated using documented assumptions and reporting boundaries
• Travel policy interventions link approval controls to measurable emissions reductions

Participants can account for Categories 8, 10 and 11 using operational and product assumptions.

• Leased-asset categories determined by operational control and lease classification

• Functional units establish comparable product-service emissions calculations
• Scenario analysis tests consumer behaviour, electricity grids and product lifetimes
• Product-design decisions connect energy efficiency with Category 11 reductions

Participants can address Categories 12, 14 and 15 with documented ownership and allocation choices.

• End-of-life models use material composition, collection rates and treatment pathways
• Category 12 distinguishes packaging, products and disposal responsibility assumptions
• Franchise emissions allocated using operational data, revenue or floor area
• Category 15 boundary identifies equity investments, debt holdings and project finance
• PCAF Standard supports financed-emissions data quality and attribution methods
• Investment inventory reconciles holdings data, valuation dates and asset classifications

Participants can evaluate Scope 3 data quality and build a proportionate improvement plan.

• Pedigree matrix records representativeness, precision and data collection methods
• Data-quality dashboard highlights category weaknesses and improvement priorities
• Primary-data roadmap sequences supplier requests, system upgrades and governance actions
• Cost-benefit analysis tests whether improved data changes management decisions

Participants can create supplier data and decarbonisation engagement approaches for priority categories.

• Supplier code requirements define emissions disclosure, targets and evidence expectations
• Request templates distinguish corporate inventories from product-level carbon footprints
