Clean Cars laws have now been implemented by fifteen states and the District of Columbia,
based on California's emissions and fuel economy criteria.
Following "a vigorous stakeholder engagement process over the last year," the state Environmental Improvement Board,
along with the City of Albuquerque-Bernalillo County Air Quality Control Board, overwhelmingly decided to approve Clean Cars rules.
The Clean Cars requirements are divided into two categories: zero-emission vehicles (ZEV) and low-emission vehicles (LEV).
The former needs automakers to sell a growing number of plug-in cars, while the latter demands reductions in greenhouse gas and other air pollution emissions.
