The California Air Resources Board is reportedly considering a new plan to help transportation for low earners: buying them cars. The agency would like to give those of low income a voucher to buy energy-efficient vehicles like the Nissan Leaf, which has a sticker price of $21,000. The board currently gives drivers $1,000 to $1,500 to get rid of their older vehicles in an attempt to curb carbon emissions; there is a second program that gives up to $4,000 depending on the vehicles involved.
