Reducing Climate Pollution from Transportation
Transportation accounts for roughly 38% of Oregon's greenhouse gas pollution. To meet Oregon's pollution reduction goals, we must improve vehicle efficiency, make fuel cleaner, and reduce how much vehicles travel.
Two of these three actions are largely handled at the state and federal levels. For example, see
Federal vehicle efficiency laws and
Oregon's Clean Fuels Program.
The third — reducing how much Oregonians have to drive — is primarily addressed at the local level. Communities can reduce pollution by bringing land uses closer together; increasing the walkability of the built environment and mixing land uses. Communities can locate retail and commercial services near residential areas, shortening the distance residents must travel. This means less driving, and allows Oregonians to take public transit, bike, or walk to where they need to go.
Every Mile Counts and
Climate-Friendly and Equitable Communities
To help reach Oregon's goals to reduce climate pollution, including Governor Kate Brown's
Climate Executive Order, Oregon created the
Every Mile Counts program – a four-agency collaboration between the Department of Land Conservation and Development, Oregon Department of Environmental Quality, Oregon Department of Transportation (ODOT) and Oregon Department of Energy.
Each agency is leading various efforts as part of the program. DLCD is leading the land use planning elements of the program, and co-leading transportation planning elements with ODOT. Most immediately, DLCD is working to improve Oregon's rules on how communities plan for transportation and community development, with a
Climate-Friendly and Equitable Communities rulemaking effort (initiated in September 2020). DLCD is also responsible for setting pollution reduction targets for each of Oregon's metropolitan areas under locally-guided scenario planning efforts (see below).
In 2007, Oregon adopted greenhouse gas emission reduction goals (House Bill 3543). The bill addressed emissions from all industry sectors and set the following reduction goals:
- By 2010, arrest the growth of Oregon’s greenhouse gas emissions and begin to reduce greenhouse gas emissions.
- By 2020, achieve greenhouse gas levels that are 10 percent below 1990 levels.
- By 2050, achieve greenhouse gas levels that are at least 75 percent below 1990 levels.
Information about Oregon's greenhouse gas reduction goals can be found in ORS 468A.205 – Greenhouse Gas Emissions Reductions Goals.
Greenhouse Gas Reduction Targets for Oregon Metropolitan Areas
In 2011, the Land Conservation and Development Commission (LCDC) adopted rules (OAR 660-044) that set greenhouse gas (GHG) emission reduction targets. This action was a response to a legislative mandate passed in 2010 (Senate Bill 1059). In May 2015, LCDC completed a required review of the rules. It approved the 
staff report and agreed that the rules should be updated to incorporate new information and to set targets for the years beyond 2035.
In January 2017, LCDC adopted amendments to the GHG reduction target rules that guide scenario planning by the state's metropolitan areas. The rules ask metropolitan areas to evaluate what changes to local and regional land use and transportation plans and programs, would be needed to reduce GHG emissions, from light vehicle travel per capita by 2040. (The year 2040 is the planning limit for most regional transportation plans.)
In updating the rules, the department worked with the Oregon Department of Transportation, Department of Environmental Quality, and Oregon Department of Energy to gather the necessary technical information. DLCD convened an advisory committee to assist in the update, including an evaluation on how scenario planning efforts can be better integrated into other metropolitan area work on transportation and land use plans. Supporting documents are linked below, along with additional information about scenario planning.

LCDC Meeting Staff Report
The 2010, the Oregon Legislature passed Senate Bill 1059, a statewide, comprehensive bill aimed at reducing greenhouse gas (GHG) emissions from transportation. The bill also created the Oregon Sustainable Transportation Initiative (OSTI) as a statewide effort to reduce GHG emissions from transportation while creating healthier, more livable communities and greater economic opportunity.
OSTI is led by ODOT and DLCD, in consultation with the Department of Environmental Quality, the Oregon Department of Energy (ODOE), and many interested party committees made up of business people, elected officials, and residents from across the state. OSTI's work consists of several components:
- Statewide Transportation Strategy
- Metropolitan Scenario Planning
- Support for Metropolitan Scenario Planning
Scenario planning is a planning exercise for exploring an area's long-term future. In other words, "where is the area heading, and is that where we want to go?" The processes outlined for scenario planning allows areas to work together to consider statewide, regional, and local needs and issues. Scenario planning studies economic development, fiscal impacts, resource use, greenhouse gas (GHG) emissions, and the effects of different choices on the state, region, community or household.
Scenario Planning Guidelines were developed as a resource to help Metropolitan Planning Organizations (MPOs) and local governments conduct land use and transportation scenario planning. We encourage MPOs to use these guidelines to design a scenario planning process that best addresses local conditions and builds on other concurrent or recent planning efforts.
In summary, GHG scenario planning is a multi-scenario analysis of how transportation or land use planning changes would affect carbon emissions over time. It includes a scenario where no changes are made, in order to compare scenario(s) with proposed changes. Scenario plans help communities assess the predicted outcome of many planning ideas. They are a good way to anticipate and quantify the long-term value of proposed plan amendments.
Strategic Assessments
Strategic Assessments are similar in purpose to scenario plans. They assess the long-term outlook of a community based on current plans and estimated growth patterns. A Strategic assessment is a voluntary activity that allows an MPO and its member local governments to evaluate what the area may look like in the future given the area's adopted plans and trends of today. Strategic assessments can help MPOs by informing development of land use and transportation plans, and investment priorities that address community goals.
To help conduct a strategic assessment, MPOs can request financial and technical assistance through contracts negotiated by Oregon Department of Transportation. Contact us to learn more.
Scenario Planning Results
Over the last five years, four metropolitan areas (Portland Metro, Eugene-Springfield, Corvallis, and the Rogue Valley) have conducted scenario planning projects. All four efforts reached the following conclusions:
- The targets are achievable, but more work is necessary.
- Meeting targets will require a comprehensive, coordinated strategy that includes a combination of complementary state, regional and local efforts that promote walkable communities and expand transportation options to reduce amount of driving people need to do.
- Substantial efforts and new funding to expand transportation options will be needed to:
- Expand public transit
- Provide incentives and price signals to promote options
- Make walking and cycling more convenient
- Promote compact, mixed use development
- Better manage parking
- Policies and actions that reduce GHG emissions provide significant benefits to Oregon citizens, businesses, communities and the transportation system because they:
- Reduce household energy and transportation costs
- Improve air quality and public health, and
- Reduce congestion and improve operation of the transportation system
- Existing plans move us in the right direction but additional efforts - to expand transit and other transportation options, better manage parking and promote compact land use - will be needed to achieve targets.
