• “LANXESS Vehicle Fleet Calculator” summarizes potential fuel savings in public and private fleets from the use of “green tires”;
• Sample fleet: High-quality tires with low rolling resistance can save millions;
• CO2 emissions can be reduced by several thousand metric tons;
• For the first time, potential savings can be calculated individually for mixed fleets;
• Program developed jointly with the Technical University of Munich.
With its “LANXESS Vehicle Fleet Calculator”, the company is now offering a tool specially designed to calculate potential fuel savings for fleets. Fleet operators can thus calculate individually how much fuel they can save by switching their vehicles to quality tires with low rolling resistance (“green tires”), the payback period for the investment and the reduction in CO2 emissions by their fleets. The comprehensive software also indicates the potential fuel savings and environmental impact of additional improvements such as the optimization of tire pressure, the front-end alignment of trucks and special driver training programs.
“For operators of large fleets, an increase of even a few cents in the price of fuel results in several thousand euros in additional costs. At the same time, on account of increasing stresses on the environment, it is becoming increasingly important to reduce the amount of CO2 emitted by cars and trucks,” says Axel Vaßen, a fleet expert and Head of International Public Affairs at LANXESS. “Our new fleet calculator lets us show operators which fuel-saving measures produce the greatest benefits, both economically and ecologically. That not only helps fleet managers save money but also benefits the environment because less CO2 is emitted.”
LANXESS developed the Fleet Calculator in collaboration with the Technical University of Munich. The tool is available free of charge on the Internet, requiring only a brief registration process, at fleet.green-mobility.com/en/
“Green tires” offer high potential savings
The selection of tires plays a major role in fuel consumption. The EU tire label has been a useful tool in this regard since November 2012. The conspicuous label rates all new tires with grades from A (best) to G on the basis of their grip on wet roads (i.e. safety) and rolling resistance (fuel consumption). “Green tires” earn particularly good grades in both categories. An example using the LANXESS Vehicle Fleet Calculator shows how much money the switch to high-performance tires can save fleet operators. For example, the operating costs of a fleet - consisting of 150 40-metric ton trucks (annual operation per vehicle: 200,000 km, fuel consumption: 35 liters per 100 km), 100 passenger buses (100,000 km, 35 liters), 75 industrial trucks with a maximum load weight of 1.5 metric tons (50,000 km, 15 liters) and 75 automobiles (20,000 km, 7 liters) - at an average fuel price of EUR 1.55, can be reduced by approximately EUR 1.4 million a year simply by switching from tires with rolling resistance Class F to B. This fleet quickly recoups the capital investment in “green tires”: The automobile tires, at a hypothetical extra cost of EUR 20 each, for example, pay off after only six months, and the truck tires, at a hypothetical extra cost of EUR 70, pay off after only three months. They also help protect the environment. Simply because of the new tires, the fleet in the above example emits approximately 2,500 metric tons less CO2 annually.
Background information: The rolling resistance of tires, i.e. the energy wasted as the tires roll along the surface of the road, accounts for 20 to 30 percent of an automobile’s total fuel consumption. On heavy vehicles such as trucks, for example, the rolling resistance accounts for up to 40 percent of the energy consumed, which is no longer available to propel the vehicle. Fuel-efficient “green tires” have a significantly lower rolling resistance and can therefore significantly reduce a vehicle’s fuel consumption while providing identical safety performance.
A calculator for all types of fleets
The LANXESS Fleet Calculator can be used by trucking companies or courier services, for example, as well as by institutions such as municipal governments and public authorities. The program takes the use of different types of vehicles into consideration, including passenger cars, industrial trucks, tractors, waste management trucks, transit buses, tour buses, snowplows, street sweepers, sewer cleaning trucks, road maintenance vehicles, trucks and fire engines. Fleet operators can use a simple template to enter the annual distance driven, the class of tires, fuel consumption, type of fuel and additional specific details for all the vehicles they operate. Individual results for mixed fleets can be calculated for the first time with this tool. After the data have been entered, the program shows both the total potential fuel savings for the fleet as well as the potential impacts of the individual efficiency measures.
LANXESS makes “green tires” possible
The specialty chemicals company LANXESS produces modern, high-performance rubber that enables the tire industry to satisfy the stringent requirements of the European Union for more environmentally friendly and simultaneously safer tires and to earn good ratings on the EU tire label for both rolling resistance and wet grip. In September 2012 LANXESS introduced a concept automobile tire which was rated "A" in both categories by TÜV Süd, thereby highlighting not only the company’s technical know-how and its capacity for innovation in the synthetic rubber industry, but also its role as a leading supplier of solutions for a more sustainable “green mobility”.
LANXESS (lanxess.com) is a leading specialty chemicals company with sales of EUR 9.1 billion in 2012 and roughly 17,500 employees in 31 countries. The company is currently represented at 52 production sites worldwide. The core business of LANXESS is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals. LANXESS is a member of the leading sustainability indices Dow Jones Sustainability Index (DJSI) World and FTSE4Good as well as the Carbon Disclosure Leadership Index (CDLI).
