Research and policy discussions highlight the role of forests in reducing greenhouse gases by storing carbon. An important factor regarding forests and carbon is simply maintaining the amount of land that is retained in forest cover. Since 1973, Oregon’s statewide land-use planning program has sought to maintain forest and agricultural lands in the face of increasing development by maintaining forest and agricultural zones and to limit growth to within urban growth boundaries. We combine projections of forest and agricultural land development with estimates of average carbon stocks for different land uses to examine what effect land-use planning has had in maintaining forest carbon in western Oregon. In addition to other benefits arising from the conservation of forestland, results indicate that Oregon’s land-use planning system in western Oregon yields significant gains in carbon storage equivalent to a reduction of 1.7 million metric tons of carbon dioxide (CO2) emissions per year.
