The Land Conservation and Development Department adopted Or. Admin. R. 660.044, Metropolitan Greenhouse Gas Reduction Targets. Changes would set light vehicle greenhouse gas emissions targets for the state's metropolitan areas for 2035. The targets are designed to guide local governments in land use and transportation planning to help the state achieve 2050 targets of greenhouse gas emissions 75% below 1990 levels. The guidelines encourage metropolitan areas to use the standards required for Portland. The regulation would include guidelines on accommodating economic development and housing needs, expanding transportation options, and reducing transportation costs to reduce greenhouse gas emissions. The rule took effect June 1, 2011. http://arcweb.sos.state.or.us/rules/July2011_Bulletin.pdf pp. 86-89.
