  • The transportation sector is now the largest greenhouse gas emitting sector. Moving to cleaner fuel sources can help reduce emissions, and can be a key component of a region’s Climate Action Plan. A dramatic shift has been occurring in the makeup of transit bus fleets, with over 17 percent of the fleet electric/hybrid in 2016. While capital costs remain higher than traditional buses, lifetime costs of battery electric buses have been shown to be lower than other fuel options with additional positive externalities. Transit agencies across the country have been taking bold steps in pursuing alternative fuel transit vehicles, with help from state and federal grant programs.​
  • Acts of Nature and Public Transportation -- November 2012
    This white paper reviews the ways in which acts of nature – particularly extreme weather events – can impact transit’s $77 billion investment backlog, identifies strategies transit agencies can pursue to reduce weather-related risks, and discusses resources and opportunities for the transit community.
  • Transit on the Cutting Edge of Clean Technology - September 2012
    This white paper reviews the substantial progress that transit agencies have made in investing in innovative clean technologies and fuels, such as electricity, hybrid vehicles, electric storage, biofuels, natural gas, and hydrogen fuel cells. Transit, in fact, has often been on the cutting edge of adopting these clean technologies, driven in part by a range of federal and state policies, programs, and incentives.
  • Potential Impact of Gasoline Price Increases on U.S. Public Transportation Ridership, 2011-2012 -- March 2011
    This study examines several sources that detail varying elasticities between gas prices and public transportation ridership. It uses those sources to predict the impact that rising gas prices will have on public transportation ridership, using APTA's 2010 ridership figures as a baseline.
  • The Route to Carbon and Energy Savings - November 2010
    This report identifies a portfolio of strategies that transit agencies can take to reduce the energy use and GHG emissions of their operations and estimates the potential impacts of those strategies in 2030 and 2050. Using interviews and current literature, a portfolio of 17 high-priority strategies were selected for analysis based on their potential for reducing GHG emissions over the medium and long term.
  • Public Transportation Saves Energy and Helps Our Environment -- 2009
  • Changing the Way America Moves: Creating a More Robust Economy, a Smaller Carbon Footprint, And Energy Independence -- 2009
  • The Broader Connection between Public Transportation, Energy Conservation and Greenhouse Gas Reduction -- February 2008
  • Public Transportation and Petroleum Savings in the U.S. Reducing Dependence on Oil - 2007
    This Independent analysis looks for the first time at what public transportation saves—both for individual households and for the nation as a whole. In addition, it explores a possible future where many more Americans would have the choice to take public transportation. APTA commissioned the report from ICF International.
  • Public Transportation’s Contribution To U.S. Greenhouse Gas Reduction - 2007
    This report will answers how much net C02 is public transportation saving in the U.S., how much additional C02 savings are possible if loads are increased,  what is the significance of non-public transportation commuter use and what can households do to save more, and finally are there favorable land use impacts that public transportation contributes to the environment and social benefits?
  • Public Transportation Reduces Greenhouse Gases And Conserves Energy
    This brochure outlines the environmental and energy saving benefits that using public transportation offers individuals and communities. Serving both as an advocacy and educational piece, the brochure contains climate change and energy conservation related charts and graphs as well as facts outlining how transit use and increased investment in transit is beneficial to future climate change and energy legislation.
    Members: up to 20 free copies/$.50 each for 21+, Nonmembers: $1.00 each, Hard copy available in the Bookstore.
  • Conserving Energy and Preserving the Environment: The Role of Public Transportation - 2002
    This report demonstrates that traveling by transit, per person and per mile, uses significantly less energy and produces substantially less pollution than comparable travel by private vehicles. The findings provide clear evidence that public transportation is saving energy and reducing pollution in America, and that increased usage could have an even greater impact int he future.
