TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 210: Input Guidelines for Motor Vehicle Emissions Simulator Model, Volume 1: Practitioners’ Handbook: Regional Level Inputs provides users of the Motor Vehicle Emissions Simulator Model (MOVES) with tools to help estimate emissions from highway vehicles.
Government agencies at all levels are increasingly setting aggressive targets to reduce greenhouse gas (GHG) emissions and mitigate the potential impact of climate change. These targets can range up to an 80 percent reduction in emissions levels by the year 2050, compared to 1990 levels.
Livability and sustainability are distinct concepts, although there is substantial overlap and they may be occasionally used interchangeably. Both notions are multifaceted, dynamic, flexible, and powerful.
