Earth Day New York sponsor Enterprise CarShare will hit the runway and display one of its hybrid vehicles during the Green Vehicle Fashion Show at Manhattan’s Union Square Park, April 21.

The company also said it will display its car-sharing technology.

The annual Earth Day celebration is a free event designed to highlight various ways New Yorkers can live and work more sustainably, including such transportation options as car sharing; and electric, low-emission and alternative-fuel vehicles.

“We believe in comprehensive, long-term local transportation planning,” said Anwar Ismael, regional vice president of Enterprise in New York, “and in supporting local citizens, business and government leaders as they advocate for a more sustainable future for their communities.”

Enterprise said that as a result, the company frequently reaches out to organizations like the Electrification Coalition, the Corporate Eco Forum, the Transportation Sustainability Research Center, the Department of Energy’s Clean Cities initiative, and the National League of Cities’ Sustainable Cities Institute — all of whom help broaden discussions about local mobility and the transportation value chain.

Enterprise CarShare is considered by the mother company as a natural extension of the Enterprise Rent-A-Car local car-rental network, which has existed since 1957.

Enterprise said it also continues to lead the home-city market with both car-rental and car-sharing options. Even before the 2007 launch of its car-sharing program, Enterprise provided hourly rentals to customers in New York and other large urban markets who rely on mass transit during the week or simply cannot afford to purchase or maintain a vehicle on their own.

In 2012, Enterprise acquired Mint Cars On-Demand in New York and Boston. Following the acquisition, Enterprise quickly upgraded the operation’s retail car-sharing fleets with newer vehicles — increasing fleet size and expanding service to new neighborhoods to better serve customers.

Now offered under the Enterprise CarShare name, these vehicles are available to members around-the-clock, and available for hourly, daily and overnight rentals.

The company also said that beyond its fleet, Enterprise recognizes that its facilities have the next greatest impact on the communities where it operates. In 2010, Enterprise committed to reduce both energy use and costs by 20 percent companywide over five years through its 20/20 Vision initiative. That impact is being realized in New York, where local energy use has been reduced by 10 percent. The facilities are working to achieve a cumulative reduction in energy use of 25 percent by 2015.
