Effective July 1, additional state taxes and fees were applied to the cost of fuels. State excise tax increased on both gasoline (1.6 cents) and diesel (1.2 cents). The Air Board’s higher cost amendments to the Low Carbon Fuel Standard (LCFS) also were finally allowed to become operative.
As provided in our new series on LCFS costs from OPIS (see below), the tighter standards under the new regulations saw the LCFS component jump 72% for gasoline and 88% for diesel. With only one month’s worth of data, however, there is no clear pattern as yet showing the effect on pump prices. Using price data from US Energy Information Administration as used by the Energy Commission, the spread in prices between the US and California for regular gasoline was 16.3 cents higher in July compared to the same month in 2023. For diesel, the spread was 6.6 cents higher. The incremental cost for LCFS combined with the higher excise tax was 7.1 cents for gasoline and 8.5 cents for diesel, but other factors likely affect the July outcomes that can only become apparent with other data points.
What is clear is that LCFS costs are being heavily moderated by one overarching factor, the substantial number of banked credits that has been built up in recent years. While the regulations require fuels to use increasing credits, prices for those credits have consequently been low, with prices driven even lower recently due to the previously-uncertain future for these rules. For example, the LCFS cost component from OPIS for gasoline was 13.2 cents a gallon in July. At credit prices that prevailed at the beginning of the year, the cost instead would have been 15.8 cents. At credit prices seen in 2020 and the first half of 2021, the cost impact would have been much higher at 44.4 cents a gallon. At the allowable maximum price this year under the regulations, the cost impact would have been 60.6 cents a gallon.
