The U.S. Environmental Protection Agency is expected to announce new regulations which are designed to dramatically reduce exhaust emissions and incentivize the use of electric cars. Rumors have circulated that the policy will apply for model years 2027 through 2032 and could result in a considerable lift in the sales of EVs. Environmental groups and some car makers are optimistic, believing it could facilitate 50% of all automobiles on American roads being either electric or plug-in hybrids by 2030.
