2005 National Emissions Inventory Data & Documentation
|Explanation of File Formats|
|General Inventory Information|
|EPA developed the 2005 NEI v2 based on a reduced level of effort. Part of this reduced effort involved using some NEI 2002 v3 data in the NEI 2005 v2 as surrogates for emissions data representing 2005. Listed below is specific information on this issue for each data category in the 2005 NEI v2.
Onroad Mobile Sources
Nonroad Mobile Sources
Prior to using the 2005 NEI for analyses, users should consider whether the use of 2002 data as a surrogate for the selected sources documented above materially affects their analysis. For example, analyses that require actual 2005 data for every source in the inventory would be limited since some sectors include 2002 emissions. Likewise, micro-level analyses focusing on specific sectors using a mixture of years would be similarly affected.
