arbcombo -- Draft Truck and Bus Sector Description Released
Posted: 25 Apr 2016 16:09:57
The California Air Resources Board (ARB/Board) announces the release of the draft document “Supporting Information for Technology Assessments: Truck and Bus Sector Description”. ARB’s long-term objective is to transform the mobile source fleet into one utilizing zero and near-zero emission technologies to meet air quality and climate change goals. This document was prepared to support heavy-duty truck-related technology assessments heavy-duty fuel cell electric vehicles, hybrid electric vehicles, battery electric vehicles, and diesel and natural gas engines. It applies to Class 2b through Class 8 heavy-duty vehicles with greater than 8,500 pounds gross vehicle weight rating. It presents a description of the truck and bus sector including truck types, vocations, emissions, and economics of the trucking and truck and engine manufacturing industries. Sources used in the draft supporting information included published reports, research papers, and ARB inventory data. The draft supporting information for technology assessments can be viewed and downloaded from the ARB’s technology and fuels assessment webpage at: http://www.arb.ca.gov/msprog/tech/techreport/t&b_sector_description.pdf If you have questions regarding the draft supporting information, please contact the following: Mr. Inder Atwal, Air Pollution Specialist, at 916-445-0281, or at Inder.Atwal@arb.ca.gov. Background: California has made substantial progress in reducing emissions from mobile sources, but further reductions are needed to meet California’s air quality and climate goals. These goals include: •Meeting 2023 and 2031 ambient ozone air quality standards, which staff estimates will require an overall 80 percent reduction in NOx emissions below today’s levels in the South Coast air basin, with substantial reductions needed in the San Joaquin Valley and other non-attainment areas of the state as well; •Meeting the newly proposed federal ozone standard; •Reducing greenhouse gas (GHG) emissions to 1990 levels by 2020; •Achieving a 40 percent reduction in GHG emissions from 1990 levels by 2030; •Achieving an 80 percent reduction in GHG emissions from 1990 levels by 2050; •Reducing petroleum use in cars and trucks by up to 50 percent by 2030; and •Producing at least 50 percent of electricity from renewable sources by 2030. Heavy-duty vehicles greater than 8,500 pounds emit about one-fifth of the total GHG emissions associated with transportation sources in the State, which is about eight percent of the statewide total. In addition, these vehicles account for 33 percent of NOx emissions from all statewide sources. Because trucking emissions are such a significant source of GHG and criteria pollutant emissions, achieving reductions within the trucking sector is a key component in the strategy to meet California’s climate and air quality goals. The technology assessments were prepared by staff from ARB, along with the South Coast Air Quality Management District staff. They were discussed at workshops in September 2014 and at the December 2014 ARB board meeting. More information on the assessments is available at ARB’s website at http://www.arb.ca.gov/msprog/tech/tech.htm. Draft technology assessments reports were released for public comments and are available on ARB’s website at http://www.arb.ca.gov/msprog/tech/report.htm. California is in a drought emergency.
