Identify, support, and recognize solutions that promote sustainable innovation to build regional resilience

Heat waves, severe weather, natural disasters, and pressure on resources—the Lyon Metropolitan Area and its surrounding region are particularly vulnerable to climate change.

Today, we need to act to limit the effects and create new solutions for mitigation and adaptation.

It's against this backdrop that SUEZ & H7 are launching the Climate Solutions Competition, to identify, support and reward innovative solutions that are working to make the region more resilient.

I'm applying

Our mission

Extreme heat, bad weather, natural hazards, pressure on resources: in the coming years, the Lyon Metropolitan Area and the Auvergne-Rhône-Alpes Region will be facing major climatic challenges.

In addition to actions to limit their impact, it is essential to develop adaptation solutions to strengthen the region's resilience in the face of these new risks.

The Climate Solutions Competition aims to identify, support and promote innovative initiatives that contribute to the circular economy and sustainable resource management.

      H7, the Lyon metropolitan area's responsible gas pedal and digital totem, supports start-ups in their growth and impact. To carry out this mission, H7 relies on three pillars: the support programs, operated by H7 and built alongside its partners; the community, made up of entrepreneurs, major corporations, talents, investment funds and partner schools; and the living space, a place for meeting and sharing, where everyone can create, learn and explore new perspectives.

        They talk about it better than we do

        Ten start-ups have already benefited from SUEZ & H7 support.

        H7 is a place where everything is possible. At the end of the mentoring program, I had a number of very fruitful encounters, particularly with seasoned entrepreneurs. The coaching enabled me to clarify our business model and draw up a strategic roadmap for the project.

        The support we received from SUEZ & H7 gave us a more global view of the sector. Above all, I remember the excellent spirit of promotion with the start-ups, meetings within the ecosystem and the excellent support provided by our start-up manager.

        Very quickly, we were able to create strong synergies with the dense ecosystem of local foodtech start-ups. H7's many strategic partnerships with private and public players have enabled us to strengthen our foothold in the Lyon area, both in terms of brand awareness and business development.
