Low-carbon fuel standard: regulations.

California AB12 aimed to modify the state's regulations on low-carbon fuel standards. The bill proposed adding a new section to the Health and Safety Code to address air pollution by potentially altering existing standards to encourage the use of low-carbon fuels.

Supporters of AB12 would argue that this bill was a step towards making California's fuel standards more flexible and responsive to the needs of businesses and consumers. They would claim it could help reduce regulatory burdens while still promoting the use of environmentally friendly fuels.

Critics of AB12 might argue that the bill could weaken California's commitment to reducing air pollution by altering the current low-carbon fuel standards. They would express concern that this could lead to increased emissions and hinder progress in combating climate change.
