Wash. Rev. Code § 70A.05.900
The legislature finds that in chapter 14, Laws of 2008, the legislature established greenhouse gas emission reduction limits for Washington state, including a reduction of overall emissions by 2020 to emission levels in 1990, a reduction by 2035 to levels twenty-five percent below 1990 levels, and by 2050 a further reduction below 1990 levels. Based upon estimated 2006 emission levels in Washington, this will require a reduction from present emission levels of over twenty-five percent in the next eleven years. The legislature further finds that state government activities are a significant source of emissions, and that state government should meet targets for reducing emissions from its buildings, vehicles, and all operations that demonstrate that these reductions are achievable, cost-effective, and will help to promote innovative energy efficiency technologies and practices.
