In 2005, NPPR began collecting data from pollution prevention programs throughout the United States for a comprehensive evaluation of the achievements of these programs from 2001 to 2003. In September 2006, NPPR released “Pollution Prevention Produces Results.”
“Pollution Prevention Produces Results: Waste Reductions, Resource Conservation, and Cost Savings” is a collection and evaluation of the pollution prevention (P2) efforts of 29 state, regional, and local governments in the United States from 2001 to 2003. the documented achievements for those three years include: over 6 billion pounds of air and water pollution as well as hazardous and solid waste that are no longer being released into the environment; a reduction in energy usage by 1.2 billion kiloWatt hours; and conservation of potable water of over 44 billion gallons. The resultant cost savings and economic benefit add up to more than $500 million. This is about 5 times the total budget for these P2 programs for the corresponding time period, and more than 25 times the federal investment.
