Lowering Emissions

The California Trucking Industry promotes green technology and innovation. 

The trucking industry is committed to meeting air quality and climate change goals and plays a pivotal role in transportation policies. Through advanced, emission reduction technologies, our industry is doing its part and taking an active role in reducing pollution from commercial trucking operations and vehicle maintenance standards. 

With some of the toughest environmental laws in the nation, the industry invests more than $1 billion annually to combat pollution and reduce greenhouse gas emissions.

Through advancements in engine technology and fuel refinements, new diesel truck engines produce 98% fewer particulate matter (PM) and nitrogen oxides (NOx) emissions than a similar engine manufactured prior to 1990.


Sulfur emissions from diesel engines have also been reduced by 97% since 1999.
