Online calculators have developed rapidly in recent years. Among the many tools available, 4 are particularly suited to the event industry:
Climeet encompasses all the emission points of an event, from the collection phase to the development of a reduction strategy. The tool processes the collected carbon data by indicating the emissions linked to each item and suggesting reduction pathways, allowing users to make informed choices and select responsible providers in advance of their event.
Offered by the French Union of Event Professions (UNIMEV) and the Paris Region Tourism Committee, Cleo allows evaluating both the positive externalities of the event activity and the negative externalities for each event, territory, and for the sector as a whole.
Greenly is an application that allows measuring the carbon footprint of an event. By considering factors such as location, transport, catering, and waste management, the calculator provides an estimate of the emissions generated by events.
Adere is a tool that allows evaluating the eco-design approach of an event. It offers practical reflection support to initiate a responsible approach for the organization and setup of a cultural, sporting, or professional event, from its conception to its realisation.
While these tools allow for a quick estimate of an event's climate impact, they are primarily intended as tools for raising awareness. They offer a summary diagnosis focused on the main emission sources.
