SERVICE 01
Service 01

Complete 3-scope Bilan Carbone®

The format for demanding organisations: Radio France (6 stations, 4,500 staff), Institut Curie across 3 sites, and ESSEC with its international travel. Scoping, structured data collection, ABC v9 modelling and a presentation to the executive committee - with uncertainties documented as they would be in a publication.

Service 02

Simplified Bilan Carbone® with support

For a service-sector SME, a scale-up or a foundation with data held centrally: a focused boundary, the main emission sources identified and an initial action plan. In Île-de-France, purchases, IT and travel quickly dominate the typical footprint - the simplified format is enough to demonstrate this with figures.
