Climate change in Washington related emissions are the dominant source of GHG emissions and have increased from 61.2 MMT CO-equivalent (CO-e) in 1990 (excluding residual fuel for transportation) to 74.6 MMT CO-e in 2004, while their share has increased from 79% of total emissions to 85% over the past fourteen years. Carbon dioxide is the dominant GHG followed by methane, nitrous oxide, perfluorocarbon and sulfur hexafluoride. Non-energy industrial global greenhouse gas emissions have lowered from 14% to 9%, mainly due to reduced emissions from aluminum production. This has been the result of two key elements: process changes that reduced CO and PFC emissions per
Sustainable urbanism reduced fuel consumption (limiting nitrous oxide, sulfur dioxide, methane, and other gases that contribute to air pollution). Additionally, reducing the overall aggregate electrical load significantly reduces carbon dioxide emissions. Improve indoor air quality by eliminating unhealthy emissions – such as volatile organic compounds (VOCs) – from building materials, products, and furnishings, and through outside filtering and distribution techniques that control pollutants. Maximize the use of controlled daylighting, which can then be augmented by high quality artificial lighting. Provide good acoustic control. Results in high performance facilities can help address a wide range of human resource concerns by improving the total
