Why are California gas prices so much higher than in Hawaii?
Gas costs well above $6 at this Chevron Station in Oakland, as seen on April 30. California has the highest gas prices in the country — far higher, even, than Hawaii’s.
TL;DR
- California gas prices are higher than Hawaii's, despite California being a top oil producer and Hawaii being geographically isolated.
- California's fuel market is isolated due to the lack of pipelines from other mainland states and a requirement for a specialized gasoline blend used statewide.
- This isolation and specialized blend force California to rely on sea-borne oil, similar to Hawaii, incurring higher shipping costs.
- Stringent environmental regulations, such as the cap-and-invest program and the Low Carbon Fuel Standard, add substantial costs (around 47 cents per gallon combined) to gasoline in California.
- Taxes, including excise and sales taxes, contribute nearly $1 per gallon to the price at the pump in California, significantly more than in Hawaii.
- Refinery closures in California and the complexity of switching between summer and winter fuel blends also contribute to price volatility and higher costs.
