Transportation comparisons including NEI, LGGIT

[eroten]

Datasets involved

• National Emissions Inventory (NEI)
• Local Greenhouse Gas Inventory (LGGIT)
• TBI (average vehicle age and gas/diesel distribution)
• EPA GHG Factor Hub
• EPA Inventory of U.S GHG Emissions and Sinks 1990-2021, state level aggregation

Summary

• Compared LGGIT emissions per mile by vehicle type to EPA MOVES
• Converted all kable tables into gt
• Completed LGGIT emissions comparison for entire region and explained likely differences
• Double checked LGGIT values against those from the 2021 EPA GHG Factor Hub (identical)
• Started to dig into state level NEI, but it seemed superfluous, given we have the county level NEI
• use consistent GWP's across calculations
• Fetch and save NEI data using their API
• new section on TBI
• added packages to renv, including srvyr
