S3Scope 3 Challenge
A simulator for corporate carbon reporting

Master Scope 3 through interactive learning.

Play through a multi-year corporate carbon program: map your value chain, wrangle supplier data, defend your inventory in an external audit, and allocate a decarbonization budget across competing trade-offs.

01
Learn the fundamentals

Bite-sized mini-games teach Scope 1/2/3 classification, categories, and data quality.

02
Run a reporting year

Map → collect → calculate → audit → strategise. Every decision has a trade-off.

03
Balance, don't optimise

Scoring rewards quality, cost, suppliers, decarbonization and SDG impact together.
