We have an obligation to protect our environment and natural resources through sustainable and responsible business practices. Not only do we comply with all applicable environmental laws, we are also committed to improving waste reduction, energy efficiency and responsible recycling. We actively promote alternative energy use in both the products we sell and our facilities. To ensure we comply with laws and our own standards, we have adopted formal environmental policies, conduct regular audits and continuously monitor our energy use and conservation efforts.
REDUCING OUR USE OF POTENTIALLY HAZARDOUS CHEMICALS. We replaced more than half of our traditional solvent-based parts washers with safer and more efficient water-based parts washers which reduced our traditional solvent usage by 50%. At our paint and body shops across the country, the paint we use contains low levels of Volatile Organic Compounds, which reduces employee exposure to harmful chemicals and minimizes our environmental impact.
IMPROVING OUR OWN VEHICLE FLEET EFFICIENCY AND REDUCING EMISSIONS. Over the past five years we have replaced more than 40% of our fleet with more fuel-efficient vehicles. These efforts, coupled with the use of our vehicle telematics systems, have saved an average of 287,000 gallons of gasoline and diesel fuel annually over the last three years.
FACILITATING THE ADOPTION OF ALTERNATIVE FUEL VEHICLES AND TECHNOLOGIES. We are facilitating the adoption of alternative fuel technologies in commercial vehicles. Cummins Clean Fuel Technologies is a leading innovator in the design of compressed natural gas (CNG) fuel systems, including its GreenLync® electronic communication fuel management system.
