    The Oregon Sustainable Transportation Initiative (OSTI) is an integrated statewide effort to reduce greenhouse gas (GHG) emissions from transportation while creating healthier, more livable communities and greater economic opportunity. The effort is the result of several bills passed by the Oregon Legislature, and it is designed to help the state meet its 2050 goal of reducing GHG emissions by 75 percent below 1990 levels.

    Since the inception of OSTI in 2010, the Oregon Department of Transportation and the Department of Land Conservation and Development have worked to plan for ways to reduce transportation-related GHG emissions and provide rules, guidelines, and tools to support metropolitan areas and other parts of the state in similar planning efforts.

    Scenario planning is the primary method recommended by the Oregon Legislature to plan for ways to reduce transportation-related GHG emissions. In scenario planning, multiple scenarios with differing land use and transportation assumptions are compared to a ‘business as usual’ future, and outcomes measured. Through OSTI, processes have been developed and tools created to support scenario planning that moves Oregon closer to achieving its 2050 GHG reduction goal, while also considering economic and societal impacts to households and businesses.

    This website features information about OSTI scenario planning efforts as well as tools to support scenario planning and other work aimed at reducing transportation-related GHG emissions.
