Inspired by proposed mandates in Europe, California Senate Bill 44, known as the “Ditching Dirty Diesel” bill, would phase out the use of diesel fuel for medium and heavy-duty truck and bus applications over the next 30 years.

The bill would require the California Air Resources Board to reduce greenhouse gas emissions by 80% by 2050.

Diesel engines make up 3% of the state’s vehicles, but contribute 23% of the greenhouse gas emissions coming from the transportation sector, according to the bill’s author, California State Senator Nancy Skinner (D-Berkeley).

According to Skinner, “We need to continue to send strong policy signals and financial incentives to spur the transition away from dirty diesel.”  

The bill is an attempt to address a rise in respiratory-related conditions impacting children and adults living within high traffic areas. 

SB44 is one of many emissions bills that challenge to bring more technology and innovation to the trucking industry.
