Scope 3 Challenge
Run a full corporate Scope 3 reporting year across three simulated years: map your value chain, spend a data budget on supplier engagement, choose calculation methods, defend your inventory to an AI auditor, then allocate capital across decarbonization levers toward SBTi-aligned targets.

Learning objectives
- Identify which GHG Protocol Scope 3 categories (1–15) are material for a given industry
- Trade off cost, effort and data quality across spend-based, average-data and supplier-specific methods
- Budget supplier engagement where primary data changes the inventory most
- Defend inclusion and exclusion decisions under external assurance questioning
- Allocate CapEx/OpEx across abatement levers and read the resulting decarbonization pathway
Learning outcomes
- A completed three-year Scope 3 inventory and reduction strategy with a scorecard
- Practical judgement on data-quality trade-offs under real budget constraints
- Experience answering auditor challenges on boundary and method choices
- A trajectory read against SBTi 1.5°C (−42% by 2030) and Net-Zero (−90% by 2040)
