Schindler Elevator Corp. has chosen to replace 500 sedans in its North American vehicle fleet with Toyota Prii.

The trim level chosen for these is the Two, which is the base model for consumers but the second-up trim level available to fleets.

These replacements will happen progressively over the next three to four years.

The company declared it expects that replacing its existing sedans with these hybrids will reduce greenhouse gas emissions by 42 percent over the company’s current sedan fleet.

“Schindler’s commitment to environmental stewardship is evident in all that we do, including: the ‘greening’ of our North American headquarters building, our sustainable ISO-certified manufacturing facilities, the environmentally friendly vehicles we use, and the energy-efficient technology we provide,” said Jakob Zueger, CEO, Schindler Americas. “We are dedicated to continual improvement to limit environmental impact.”

The company’s 2,000-plus non-sedan fleet was replaced in 2010 with the Chevy HHR, which has already saved an average of 2,358 gallons of gasoline per year, resulting in a reduction in fleet greenhouse emissions by 34 percent.
