Few Find What They’re Looking for in Changes to California’s Low-Carbon Fuel Standard

Oct 09, 2024

By Blanca Begert

California put out new proposed changes Tuesday to the low-carbon fuel standard, its credit-based program to reduce emissions from transportation fuels — but almost no one is happy with them.

The amendments — the third set of changes proposed since last December, and likely the last as the California Air Resources Board is set to vote Nov. 8 — were smaller and more technical compared with the previous set released in August. The changes garnered praise from some industry groups, consternation from others and were panned by environmentalists who argue they did not address their concerns related to incentives for biofuels.

Tuesday’s amendments include a delayed phase-out of credits for hydrogen made from fossil fuels from 2030 to 2035 and a requirement that hydrogen dispensed at fueling stations be 80 percent renewable by 2030.

Video: What Happens When Pigs Adapt to High Soybean Meal Diets? - Gustavo Lima

In this special rerun episode of The Swine Nutrition Blackbelt Podcast, Gustavo Lima, PhD candidate in Animal Science at Iowa State University, discusses how grow-finish pigs respond to high soybean meal diets. He explains the initial drop in feed intake, changes in backfat, later adaptation, energy efficiency, amino acid utilization, and the rise in nitrogen excretion at higher inclusion levels.
