Ted Kulongoski, Governor of Oregon from 2003–2011, selected the Climate Change Integration Group (CCIG) to develop a framework for making informed decisions to minimize the more extreme impacts of climate change. Kulongoski wanted the CCIG to create a strategy for Oregon to apply the measures from the 2004 Oregon Strategy for Greenhouse Gas Reductions. In this report, the CCIG proposes that Oregon takes steps toward developing a framework that will assist individuals, businesses, and governments to incorporate climate change into their planning processes.
