Green City

Healthy, successful, liveable urban spaces

Our vision

We aim to develop an international standard for green cities as well as being a focal point for green city best practice and a source of expertise.
Through world activities, research and marketing, and shared resources we seek to inspire people, organisations, city councils and government administrations to join this challenging movement and reap the benefits.

Did you know?

Already, 55% of the world’s population live in cities, and United Nation statisticians predict that this will increase to 68% by 2050.

This increase in population will require expansion in area, and in many parts of the world this will be into biodiversity hotspots. Cities need to incorporate nature as part of dedicated conservation efforts, and as part of their own sustainability and resilience.
