GreenStep City Best Practices Environmental Management

Sustainable Purchasing
no. 15

Adopt environmentally preferable purchasing policies and practices to improve health and environmental outcomes.
  • Green purchasing standards, benefit calculators and more are available on the U.S EPA's greener products and services page. Benefits include cost, environmental and improved worker productivity and improved public health.
  • See benefit calculators for paper, electronics and ENERGY STAR-certified products.
  • Ductile iron pipe for drinking water mains has stronger walls allowing a larger inside diameter reducing friction and thus saving energy. According to St. Cloud’s Pumping Cost Study (July 2014), the city's use of ductile iron pipe (certified under the SMaRT standard ) results in an annual savings of $210,530 compared to competing pipe, measuring power cost, pump efficiency, and head loss.
Step 3 recognition minimum for category A, B and C cities
All Category A, B and C cities are recognized upon completion of action 1.

Category A and B cities also complete at least one additional action for recognition.
Sustainable purchasing, also known as environmentally preferable purchasing (EPP), shifts city purchasing to procurement of goods and services that have a reduced effect on the natural environment and human health when compared to competing products and services that serve the same purpose. While life-cycle assessments offer the best metric for determining what is the most sustainable, product and service attributes are commonly used as a proxy, and include:
  • Increased energy efficiency
  • Reduced toxicity
  • Beneficial to indoor air quality
  • Water-conserving
  • Recycled-content
  • Minimized waste
  • Plant-based
  • Locally produced
  • Embodied energy/life-cycle greenhouse gas impact
