Consumer Climate Change Index
This indicator tracks purchases made in Washington and measures the output of greenhouse gases related to product life cycles. The index shows how consumer purchasing patterns and habits affect climate change. Making and consuming products significantly impacts greenhouse gas production according to the U.S. Environmental Protection Agency (EPA) studies.
Climate change tied to greenhouse gases, such as carbon dioxide and methane, constitutes one of the impact areas measured in the Washington Consumer Environmental Index (CEI). Greenhouse gases are emitted during the manufacture, use, and disposal of a product. The CEI tracks the environmental effects of consumer purchases.

The aggregate emissions associated with climate change as measured by this indicator are increasing. Between 2000 and 2007, there was an approximate 26 percent increase in greenhouse gas emissions, or 28 million tons of carbon dioxide equivalent emissions. These greenhouse gas emissions are generated in our state, other areas of the country, and abroad. Many of the products purchased in this state originate abroad, but since data is not available for emissions associated with manufacturing in other countries, the indicator measures only emissions generated from manufacturing within the United States. The increase in greenhouse gas emissions is primarily due to an increase in purchases of products in Washington that have a higher rate of emissions related to the manufacturing of those products.
The emissions based on per dollar spent declined approximately nine percent between 2000 and 2007. This is due to consumer purchasing decisions reflecting a decrease in greenhouse gas emissions associated with the goods and services on a per dollar basis (fewer emissions per dollar, but more overall as shown in the per person and aggregate indicators).
In the case of greenhouse gases from consumer activities, about 75 percent of emissions occur in the production and transportation phase, close to 25 percent occur during the use phase, and less than half a percent occurs during the disposal phase.
Consumer Purchases with Largest Increases in Greenhouse Gas Emissions, 2000-2007
The consumer purchases listed in the table below increased most significantly from 2000 to 2007. Therefore the CEI shows greater emissions associated with the activity.
Why should we be concerned about our state's climate change index?
Climate change is a collective, global problem that will affect everyone, and requires everyone's effort to solve. Washington's consumers can play an important role in solving this global dilemma. Washington's economy is approximately the 14th largest in the nation, and the 40th largest in the world.
