SOL is turning even greener.

SOL Green Capital is the Green and Circular economy vertical of Smart Open Lisboa (SOL), the startup implementation program focused on the validation and integration of innovative solutions made to upgrade city life.

Through the European Green Capital 2020 award, Lisbon is recognized for its work over the last decade in sustainability and green innovation, presenting itself as a people-friendly city. This is the first time that a Southern European capital has won this distinction, that SOL Green comes to complete.

The selected solutions for the program will have a one-time opportunity to get support and direct access to key corporates and validate their solutions using real data in a live environment while working directly with potential customers and/or partners.
