How Companies Should Compare the Platforms
Companies should first identify their emissions sources, reporting requirements, business size, Scope 3 needs, and sustainability goals. They should then compare platforms based on data collection, reporting, calculation methods, compliance support, and sustainability tracking.
For smaller businesses, simple data collection and reporting may be the main priorities. Larger organizations may need advanced Scope 3 management, supplier data collection, audit trails, integrations, and detailed sustainability planning.
