natureplus - European quality standard for construction products
natureplus is an ecolabel for construction products, developed over the last decade in a multi-stakeholder partnership with industry, WWF, FSC and Greenpeace.
It is widely established throughout Europe and has advantages over both the Green Guide (please see our critique here http://pinpoint.ukgbc.org/resource/7479 and please add your comment) and EPDs, in that it is only awarded to leading sustainable products and it has strict criteria for safeguarding health and interior air quality with limits on VOCs. It is also transparent and 3rd party accredited.
natureplus are developing a database which will be free to access which will list product impacts, embodied carbon etc.
