Why it matters locally: The sustained higher cost of diesel fuel significantly impacts Arizona's transportation, agriculture, and mining sectors, which heavily rely on diesel-powered vehicles and machinery for operations.
Diesel fuel has consistently been more expensive than regular gasoline since 2004, with only occasional exceptions. This pricing trend marks a change from earlier periods when diesel typically cost less. Three primary factors account for this reversal: evolving air quality standards, shifts in market demand, and adjustments to taxation policies. Before 2004, diesel prices often fell below those of gasoline. The subsequent policy and market changes altered this long-standing relationship.Related Topics
