To avoid the environmental consequences of extracting and processing virgin materials by using recycled and reclaimed materials.
Use materials for new infrastructure such that the sum of the postconsumer recycled content, on-site reused materials and one-half of the preconsumer recycled content constitutes at least 50% of the total mass of infrastructure materials.
Count materials in all of the following infrastructure items, as applicable:
- roadways, parking lots, sidewalks, unit paving, and curbs;
- water retention tanks and vaults;
- base and sub-base materials for the above; and
- rainwater, sanitary sewer, steam energy distribution, and water piping.
Recycled content is defined in accordance with ISO/IEC 14021, Environmental Labels and Declaration, Self-Declared Environmental Claims (Type II environmental labeling).
