College campuses have become the latest front in the battle for local supremacy in the car-sharing market. “For us, it was a no-brainer,” said Michelle Lai, Temple’s assistant vice president for strategic initiatives and sustainability. “We’re always interested in improving the sustainability options for our students.” Temple has five PhillyCarShare lots on its campus. Those lots include two of the 20 charging stations for electric cars whose installation was funded by the city of Philadelphia from a grant provided by the state.
