What Determines Diesel Fuel Cost

---

Diesel prices in the U.S. are significantly affected by several factors, including environmental regulations, state taxes, and global economic conditions. Higher taxes, especially in states like California where the diesel tax exceeds $1 per gallon, aim to promote cleaner energy use but directly increase transportation costs​. Stricter emissions standards and fees on diesel contribute to elevated prices, as compliance requires additional refining and production efforts. [1][2]

Global factors, such as OPEC's production adjustments and geopolitical tensions, also play a role. For example, supply chain disruptions and shifts in crude oil prices often translate to higher costs for diesel. These dynamics not only impact truckers but also influence broader logistics expenses, including consumer costs for goods​.
