Cleo Carbone, for UNIMEV
The events industry's carbon accounting tool, with standardised collection and shared data.

Where it started
A trade show, a stand or a venue involves dozens of stakeholders. Without a common model, each collects data in its own way and assessments cannot be compared from one edition to the next.
What we built
-
Ready-made structures: multi-site event, stand, venue. Every assessment starts from the same grid.
Collection templates
-
A project is described in plain language, and Klem proposes a complete structure with its perimeters and emission sources.
Assisted generation
-
Each stakeholder contributes to the shared assessment and keeps control over what they share.
Data sharing
What it changes
The industry has a common collection method: assessments become comparable from one event and one year to the next.
