Great Britain’s NetMovers.co.uk is listing the Energy Performance Certificates of all properties on the site on a scale for A to G and a color code from green to red indicating energy efficiency.

“We believe our users should have the opportunity to view property by its efficiency,” explained Rick Jones, NetMovers’ operations and development executive. “It is our individual responsibility to do everything within our power to reduce our contribution to global warming, but at the end of the day the facility will be there for people to use and we will see if it is popular or not.”
