About the IEFS Initiative

The International Ecocity Framework and Standards (IEFS) initiative seeks to provide an innovative vision for an ecologically-restorative human civilization as well as a practical methodology for assessing and guiding progress towards the goal.

The ecocity approach to sustainable development seeks to maximize the possibility that cities can become more resilient by sustainably meeting a majority of their needs from the natural capital of their own bioregions.

Cities and citizens maximize resilience through a whole systems approach that responds to critical risk factors for climate change and natural disasters while concurrently working with a network of cities around the world taking action to restore planetary boundaries to safe and stable conditions.

Towards this goal, the International Ecocity Framework and Standards (IEFS) initiative, launched in February 2010, is currently under development by nonprofit Ecocity Builders and an international committee of expert advisors.

The negative impacts of cities on the environment have been profound. Cities can and must be re-designed to build soil, restore biodiversity and return the climate to dynamic stability — becoming net positive contributors to nature as well as to human culture. — Richard Register, President, Ecocity Builders
