Protect the Health Environmental program 2010 The Ecocycle Councils objectives Energy conservation Reduce landfill Reduce hazardous substances Healthy indoor environment Noise reduction Avoide Moisture Problems Reduce Landfill! Objective: To halve the volumes of landfill wastefrom construction works between 2004 and 2010. 3
Hazardous Substances Objective 1: The use of hazardous substances should be reduced to a minimum by 2010. Objective 2: By the year 2006 the main part (> 3/4) of the building products should have Building Product Declarations. Building Product Declarations Self declaration by producers Type II declaration a standard, within the trade, according to the principles of ISO 14021.
