States that, if a rule is created that regulates greenhouse gas emissions of agricultural activities and food processing, the producers of agricultural commodities or food products may request the department of ecology to calculate greenhouse gas emissions in a comparison of a specified competitor's agricultural commodity or food product imported from out-of-state against the same type of agricultural commodity if obtained in the state.

Requires the department of commerce, in consultation with the department of ecology, transportation-industry experts, and other business-related interests, to create a greenhouse gas emissions shipping modeling tool that allows a producer of a product to estimate the amount of greenhouse gas emissions produced when importing products and goods from out-of-state locations.
