Greenhouse Gas Emissions

California air regulators on Friday approved a contentious overhaul of the state’s carbon market, creating a program that could steer billions of dollars in free pollution permits to oil refineries and other major polluters over the objections of environmental groups, key lawmakers and three of the board’s own members. Ten members of the California Air […]

California is considering handing oil refineries and other major polluters billions of dollars in free emission allowances just as the state says carbon reductions need to come faster than ever. In the last six months, two refineries have closed and gas prices have topped an average of $6 a gallon as the Iran-Israel war sent […]

New regulations by the air resources board are better for oil refiners but the state will get less auction money to use for wildfire prevention and other projects.

Climate programs cause smaller costs in California's gas prices, but the limited supply routes and a highly concentrated refining market cause bigger price boosts.

Proposed changes to state climate law may boost gas-pump prices by up to $1 a gallon by 2030. Also more refineries and jobs may leave California.

The rules would hold pollution magnets like warehouses, ports and railyards accountable for the trucks and ships they attract.

California built a first-in-the-nation system to police refinery profits during price spikes. Regulators delayed it for five years.

Plastics are the most sustainable option. Food suppliers are decades away from other material that performs as well at food safety and waste.

With some California gas prices topping $5 a gallon, anything that pushes prices even higher, like emissions crackdowns, will become a political football.

California trucks much of its organic waste to landfills instead of recyclers, largely because of an exclusive franchise hauling system.
