The California Air Resources Board (CARB) has enacted new regulations that will require “zero emissions” trains to be introduced after 2030, focusing on a sector often seen as a “green” alternative to cars and trucks.
The San Francisco Chronicle reports:
Under the new regulations, zero-emissions models will be required for all switch, industrial and passenger locomotives built after 2030 and for all freight line locomotives built after 2035. Any non-zero emissions locomotive that is 23 years old or more will not be allowed to operate in the state past 2030.
The regulations also require train operators to open a spending account by July 2024 that they must deposit into every year to purchase or lease cleaner diesel trains and buy zero-emissions infrastructure. Operators that generate more pollutants are required to deposit more into the spending account, and the amount required to be deposited would also increase every year.
It is unclear how the new regulations on trains would affect interstate commerce, which is regulated by Congress under the U.S. Constitution, since many trains in California also travel through other states.
Last August, CARB finalized regulations that ban the sale of gas-powered cars in the state after 2035. California also plans to ban diesel and gas-powered trucks by 2040, and will require all-electric trucking fleets by 2042.
It is unclear how the state’s electrical grid will support all of the “zero emissions” vehicles demanded, since it is already struggling to provide enough electricity to charge a limited number of electric vehicles at peak demand.
