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

  • Collection templates

    Ready-made structures: multi-site event, stand, venue. Every assessment starts from the same grid.
  • Assisted generation

    A project is described in plain language, and Klem proposes a complete structure with its perimeters and emission sources.
  • Data sharing

    Each stakeholder contributes to the shared assessment and keeps control over what they share.

What it changes

The industry has a common collection method: assessments become comparable from one event and one year to the next.

We start with a diagnostic: what can be built, what should not be, and what it will return.
