55 Green City Innovations

These green city innovations range from self-sustaining villages to urban forest pavilions. Aiming to make urban spaces more communal and eco-friendly, architects are re-adapting public parks, skyscrapers, and offices to feature elements like indoor gardens and lush, growing facades.

As cities become more populated, an increase in construction means sparser green spaces, but products like indoor gardening kits, and hydroponic planters are ensuring consumers can create indoor gardens where outdoor growing space is limited.

While standouts like 'Motorleaf' -- an intelligent device that tracks indoor gardening growing conditions -- are ideal for city dwellers looking to cultivate their own food sources indoors, Amazon's new Seattle headquarters gives employees access to a communal greenhouse space, consisting of "more than 3000 species of plants."
