(Portland, OR)  --  Portland city officials are considering adding a new tax to pay for climate initiatives.  The Oregonian reports that a draft plan from Portland's Bureau of Planning and Sustainability would target facilities that emit large amounts of carbon and other pollutants.  Facilities that could be targeted would include factories and manufactures, as well as colleges, universities and potentially hospitals.  The plan would generate ten-million dollars a year for Portland, which would then go to fund investments in clean energy and public transit.
