The Living City will integrate nature into the very fabric of urban planning, defend trees, plants, animals, rivers and greenspace and solve challenges by working with – not against – nature.

Active City

The Active City will build safe streets for all users, ages and abilities; focus on moving people, not just cars, and connect communities with world class transportation.

Renewable City

The Renewable City knows that 100% renewable energy is 100% possible; says “no” to new fossil fuel infrastructure, and creates clean energy jobs.
