An event that plays its part in decarbonisation!

The building and construction sector emits 145Mt of CO2e a year. Together with transportations, our sector is the main emitter of CO2 and is therefore a key priority if France’s decarbonisation strategy is to succeed!

Conscious of the environmental and societal challenges to which we must respond collectively, Idéobain is committed to a long-term strategy aiming to reduce its impact on climate, the environment and biodiversity as much as possible.


Since the 2022 edition, we aim to raise awareness among our stakeholders on the importance of these issues, but above all, to set an example for our exhibitors, our visitors, our partners and our teams. This is the first step in a voluntary strategy to make the organisation of our events exemplary in reducing our impact on climate, the environment and biodiversity. With more than 300,000 participants and more than 2,000 exhibitors attending the show, this represents a sizeable challenge.

This ambitious strategy is based on a comprehensive approach which includes a recognised scientific method and a concrete, transparent action plan with measurable indicators.

1st step: measure our GHG emissions with a Carbon footprint report®

With the help of EcoAct, a climate and carbon strategy consultancy, we decided to produce a provisional Carbon footprint report using the Bilan Carbone® tool on scopes 1, 2 and 3. This allowed us to establish the orders of magnitude of our emissions and identify the actions to be implemented for the 2024 edition. This Bilan Carbone® methodology enabled us to collect valuable data on our direct and indirect emissions from:

  • Exhibitor and visitor travel;
  • Inputs (purchases of goods and services for the show);
  • Generated waste by the show;
  • Energy consumption (electricity, natural gas);
  • Transport of show inputs;
  • Coolants;
  • Fixed assets.

2nd step: create a roadmap

Based on the Bilan Carbone® data, the entire Idéobain team took part in a series of consultation workshops aimed at identifying appropriate actions to reduce our footprint since 2022.

  • Exhibitor and visitor travel, which represents 81% of our carbon footprint, or 26,000 tonnes of CO2e,
  • Materials and purchases (inputs) come next: 18% of our carbon footprint, or 5,800 tonnes of CO2e.
  • Waste, which represents 1% of our footprint, or 245 tonnes of CO2e.

3rd step: set goals and launch an action plan

  • Raise awareness and help visitors make responsible transportation choices
  • Facilitate shared and optimised transportation solutions for exhibitors
  • Promote and encourage exhibitors to choose eco-designed stands
  • Effectively reduce, sort and recycle all waste generated by the show
  • A comprehensive plan of action by theme along with specific objectives has been drawn up for this 2024 edition and will soon be published online
