Carmel joined the growing number of jurisdictions in california on Tuesday, by banning plastic, single-use bags in the city. the bag ban allows 6-months for local businesses to use their remaining supply, before merchants must stop offering them. The measure does not include a tax for a paper bag. Preliminary approval was given unanimously on tuesday; final approval is expected to come next month. meanwhile, Monterey county supervisors are considering a plastic bag ban in unincorporated areas of the county.
