California Looks at Ways to Eliminate Diesel by 2050

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.
