A comprehensive climate action plan for the Seattle-Tacoma-Bellevue Metropolitan Statistical Area covering King, Kitsap, Pierce, and Snohomish Counties. The plan provides greenhouse gas emission reduction strategies across six sectors: built environment, transportation, waste, natural lands, refrigerants, and consumption.

Community Projects are a recent innovation in the State Legislature. Essentially, House members sponsor their own grants which are funded as capital projects. In this case, $340,000 is being allocated for two ultrafine particle monitors to be handed off to Puget Sound Clean Air Agency (PSCAA). One will be in Chinatown, at the confluence of

There is this form of air pollution, which you probably have not heard of, called ultrafine particulates (UFPs). Though they are invisible, they seem to have some particularly nasty effects on human health. UFPs have not been well-studied, they are unregulated, and yet they are prevalent in commercial jet engine emissions. But this is not
This post describes a proposal we have put forward to Washington State legislators Senator Karen Keiser (33rd) and Representative Jesse Johnson (30th). In one sentence, we want an annual report of all key aviation-related emissions for every neighborhood affected by the operations from Sea-Tac Airport. We refer to this proposal as Sea-Tac Airport Annual Air
Hi Rep. Orwall, Thank you for your time on the phone today. BACKGROUND As I said, I have a lot of experience as a consultant with the environmental monitoring and mitigation process of conventional businesses (ie. where NEPA is governed by EPA.) It has always been annoying to me that the airport (being governed by

The Puget Sound Clean Air Agency conducted this screening study to identify chemicals and emission sources that pose the greatest potential health risks to citizens in the Puget Sound region. We also hope to better characterize the potential health risks to our three million residents from a group of air contaminants referred to as air
