In 1993, Portland became the first city in the nation to adopt a CO2 emissions reduction strategy. Portland and Multnomah County worked together under ICLEI's CCP program to develop a Local Action Plan on Global Warming. The Plan focuses on five action areas: transportation, energy efficiency and green building, renewable energy resources, waste reduction and recycling, and forestry and carbon offsets. Since 2005, Portland has required public construction and renovation projects to meet LEED certification standards. Portland also requires that 10% of its energy be obtained from renewable sources. Portland and Multnomah County have been able to reduce per capita greenhouse gas emissions by 12.5% since 1993.
