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 applicable 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%. We are also focusing on upgrading HVAC systems to both eliminate the use of more potentially harmful refrigerants that contribute to greenhouse gases and reduce our overall energy consumption. 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. The Company continues to seek to improve the overall fuel efficiency of its fleet by transitioning from eight-cylinder engines to more fuel-efficient four- and six-cylinder engines. The Company is also making investments to replace aging vehicles with more fuel-efficient vehicles, including electric vehicles, as well as in EV charging stations.
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.
