The DRAFT Clearinghouse of diesel engine emissions data has been provided below to local air district staff for district staff to review. The MS Access database is linked below, and each file is also provided in MS Excel format.
The data has not been reviewed or evaluated by ARB. This data is for review only. Most of the emissions data is incomplete, the fuel may be unspecified, and the study and data may not have been peer-reviewed. Some of the reports are no longer available. ARB staff does not have copies of any of these reports.
