Global Context, Local Action

Fossil fuels burned for road, rail, air and marine transportation together comprise the fourth-largest contributor to global greenhouse gas emissions17, with significant climate change and human health implications.

In the United States, and in New Jersey, transportation activities are on par with electricity production as the largest sources of emissions18,19, making the transition to green transportation solutions a top priority.

The University has responded with a Transportation Demand Management (TDM) program to promote ridesharing and the use of public transportation, increasing the number of commuters using these and other alternative modes.

Short and Long Term Objectives

Princeton’s strategies support commuters in transitioning toward more sustainable transportation modes through an expanded transportation demand management (TDM) program called Revise Your Ride. The University also is expanding access to on-campus and regional transportation services and supporting more widespread availability and use of electric vehicles.

Princeton’s Progress To Date

Princeton’s efforts to date to reduce the number of single-occupancy vehicle (SOV) commuters to campus through its TDM incentive program have exceeded expectations. Between 2008 and 2017, the program contributed to shifting the behavior of 750 former SOV drivers toward alternative modes, including rail and bus transit, carpools, vanpools, and biking or walking.

As of 2018, 1,664 faculty and staff members — or 25 percent of all commuters — use more sustainable alternatives to SOVs, contributing to improved regional air quality, reduced traffic congestion and reduced greenhouse gas emissions. Princeton also offers affordable car share programs that are increasing in popularity.

Revise Your Ride

Revise Your Ride is a new TDM program informed by behavioral science to increase commuters using alternative modes of transportation, and to decrease single-occupancy vehicles.

Campus Action Items

  • Expand transportation demand management strategies, including increased access to on-campus and regional transit services, and enhanced on-campus and regional cycling and pedestrian infrastructure.
  • Track and reduce, where possible, greenhouse gas emissions from all campus transportation and fleet operations.
  • Advance evidence-based transportation solutions by encouraging students, faculty and staff experts to engage as advisors and researchers using the campus as a lab.
  • Encourage lifelong sustainable transportation habits by promoting walking, biking, videoconferencing, vehicle sharing, consolidated trips and other alternatives.
  • Scale action beyond Princeton through information-sharing and partnerships with, for example, local municipalities, regional transit authorities, and peer networks.
