“We are excited about deploying this new alternative fuel product in our fleet. We expect it to lead to significant cost savings in both fuel usage and maintenance intervals.” — Tom Armstrong, director of fleet, ThyssenKrupp Elevator.

“I put in a lot of time and thought evaluating other alternative fuels. Propane autogas stood out as a responsible fuel, sourced in America – specifically in Texas – that could take my company to the next level of protecting our environment while securing our bottom line.” — Gary Kulp, president, Austin Gutter King.

Contractors Take Bold Steps to Leave a Smaller Carbon Footprint

Competition among contractors is leading many customers to choose service providers that not only offer the best price, but one that protects our planet’s natural resources along the way. Reduce, reuse, and recycle are becoming the mantra of contractors everywhere, and ROUSH CleanTech is answering this call with a lineup of propane autogas powered Ford trucks and vans that reduce greenhouse gas emissions and lower operating costs.

President Gary Kulp has taken many steps to reduce his company’s carbon footprint by using wind to power their shop, rainwater to wash fleet vehicles and an extensive recycling program. The next logical step, according to Kulp, was to power their fleet of service vehicles with green alternatives. By adding three propane autogas powered Ford F-150 pickups and one fully customized Ford E-350 cutaway van, the company has reduced carbon emissions by nearly 98,000 pounds per vehicle over the 200,000-mile life of each truck and van.

To strengthen its sustainability efforts, reduce transportation costs, and cut pollution, ThyssenKrupp Elevator, the world’s premier manufacturer, installer, and service provider of vertical and horizontal transportation technology, is also using ROUSH CleanTech autogas propane vehicles in various markets across the nation. The company, which runs a fleet of 3,300 vehicles in North America, has the potential to remove nearly 323 million pounds of carbon emissions each year by switching their entire fleet to propane autogas.

On the financial side, estimates show that by using propane autogas, a company can significantly reduce maintenance costs through less frequent oil changes. The life of each engine can also increase compared to the same gasoline-fueled fleet vehicle.
