On December 1 and 2, 2026, at Paris Expo, Porte de Versailles (Hall 1), Reed Expositions organizes STEP, the Ecological Transformation Exhibition by Pollutec. Renamed after the Paris edition of Pollutec, this event brings together manufacturers, eco-industrialists, local authorities and investors to discuss concrete solutions for accelerating the ecological transition in France and Europe.
Structured around two main themes (decarbonization and the circular economy), the show features conferences, themed workshops, B2B meetings and areas dedicated to startups. It also hosts the STEP Innovation Challenge and a Talent Hub designed to put companies in the sector in touch with job seekers.
Historically, Pollutec Paris has been a benchmark event for players in the fields of air quality, environmental measurement, atmospheric emissions monitoring and treatment and purification technologies. This new edition, under the name STEP, builds on this heritage, broadening the scope to include all aspects of industrial transition.
