For the first time, Pollution Prevention and Source Reduction Assistance Grants (between 2011 and 2022) have topped the one-billion-pound mark for reductions in hazardous materials and pollutants. In addition, cost savings of $2.3 billion resulted from companies buying fewer hazardous materials and shipping less hazardous waste, reducing regulated air emissions, treating less wastewater and buying less water, fuel and energy. Further success from these grants includes 20.8 million metric tons of greenhouse gas reductions and 31.9 billion kilowatt hour savings achieved mostly through energy efficiency and reduced use of energy.
