Only one state is allowed to set its own emissions standards. The waiver has made it a green leader

California’s powerful Air Resources Board recently passed new regulations that essentially require all vehicles sold in the state to be electric, hydrogen-fueled or at least plug-in hybrid by the year 2035. What’s more, 17 other states have agreed to follow California’s lead, at least to some degree, in matters relating to air pollution, so many of those states could also adopt these requirements.
