Transportation is one of the fastest growing sectors of greenhouse gas (GHG) emissions globally. While emissions are still higher in developed countries, they are growing more rapidly in developing nations. There are opportunities for transportation demand management (TDM) strategies to help address climate change by reducing vehicle miles traveled and encouraging more efficient modes of transportation. TDM can appeal to individuals, businesses, and political leaders by highlighting its benefits for issues like congestion, air quality, public health, cost savings, and energy independence in addition to environmental and climate impacts. Surveys show many individuals are willing to make lifestyle changes to help the environment, and some businesses see opportunities to gain competitive advantages through reducing their carbon footprints.
