Developed by UNIMEV (the French Meeting Industry Council) and the Paris Region Tourist Board, and funded with the participation of the Paris Exhibition Committee, the Calculator Cleo has been up and running since December 2015. Its current 2.0 version has been programmed by Deloitte on Pure Platform, an IT reporting solution by UL. Universal, leverageable, upgradable and open, its methodology is based on:

• the consultation of an expert Scientific Committee made up of professionals, association representatives and public players,
• the results of socio-economic partner studies conducted with the French Ministry for the Economy, Atout France (the French Tourism Development Agency), UNIMEV, OJS (statistical agency for trade shows and fairs), France Congrès, the Paris Region Chamber of Commerce and Industry, the Paris Exhibition Committee, Viparis and OTCP (Paris Region tourism office),
• the results of Explori surveys on attendee satisfaction,
• the ADEME’s “Base Carbone” Database (the Environment and Energy Management Agency of the French Ministry for the Environment).

The Calculator Cleo is an IT platform which assesses the impacts of events and event places. Through data inputs, professionals generate estimate or actual reports compiling up to 72 strategic indicators, which can be steered and leveraged and are broken down into 3 categories:

  • meeting performance” (business, scientific and reputation developments of the managed stakeholder communities),
  • event and tourism spin-offs” (economic, labour and tax spin-offs) for destinations,
  • environmental balance” (carbon footprint, consumption, waste management and positive initiatives).

These reports can feed into the sales, marketing, institutional and CSR actions and arguments of event organisers and event venue managers.


the marketing indicators

The human encounters created by events are of significant value. Cleo generates 15 indicators focused on proving and enhancing events’ marketing dimension, structured around the concept of “meeting performance”. Events’ publics, whether physically present or active on social networks, make up constantly managed stakeholder communities, their interactions contributing in particular to developing the business, knowledge and influence of a company or industry.

• Business dealings between participants make events tangible tools for prospecting and sales and even, for the more international events, genuine hubs of global trade and springboards for French companies to boost their exports. Events reflect industry-specific dynamics, and can even anticipate them!

• Showcases of the state of the art and advances in an ecosystem of stakeholders, events are platforms for knowledge sharing and technology transfers. Events can offer accredited training, a selection and promotion of scientific publications and the participation of R&D bodies.

• Through the conversations they give rise to, events are vehicles for engagement and influence. The levels of reputation of a meeting (satisfaction / recommendation), of reactions on social networks (impressions / engagement rate) and of media coverage of content (number of people watching/listening) can be used to measure the scope of influence of an industry or stakeholder community through events.


environmental challenges

As with all human action, events have an environmental footprint. This is a key challenge concerning professional responsibility, the sustainability of event business, communication to stakeholders (clients, partners, sponsors, shareholders, local and regional authorities, NGOs, etc.), compliance with current and future regulations (carbon tax / carbon market) and civil society’s acceptance of key future events.

Committing to a sustainable development policy requires an assessment of major impact components: Cleo calculates the key indicators such as events’ carbon footprints, waste production, and water and energy consumption. This initial level of environmental expertise is a prerequisite for any evidence of long-term corporate commitment to sustainable development:

  • indicator management: Cleo assesses results over time, from one event session to another,
  • environmental initiatives: Cleo suggests the implementation and assessment of initiatives in favour of the circular economy (sorting and recycling of secondary resources), responsible catering (environmentally-responsible labels, short circuits, surplus food redistribution) and low-footprint transportation,
  • carbon neutrality: Cleo measures the level of greenhouse gas emissions to be offset,
  • labels / certification: Cleo can be used as a management tool as part of a certification approach, in particular for the ISO 20121 international standard on “sustainable management for events”.

Lastly, for companies which communicate on their CSR reports, Cloe can be leveraged to measure events’ environmental efficiency with regard to their economic, labour and tax spin-offs which benefit places & destinations.
