"The U.S. Environmental Protection Agency (EPA) said it was seeking input in its $3 billion Clean Ports Program to reduce pollutants at U.S. ports and its $1 billion Clean Heavy-Duty Vehicle Program to reduce vehicle emissions near ports and other truck routes. "
" California regulators last week approved new rules requiring all medium- and heavy-duty vehicles sold in the state in 2036 be zero-emission and new reduced emission regulations for locomotives. Big rigs, local delivery and government fleets must transition to zero emission by 2035, garbage trucks and local buses by 2039, and sleeper cab tractors and specialty vehicles by 2042."
