Total GHG emissions by NAICS-6

[nacho-osio]

Hi,

As versions v1.1.1 and v1.2 of GHG emission factors are classified by NACIS-6, I would like to access the total emissions by NAICS-6 as well.

Where could I get this information?

The emission factors are based on totals developed in EPA’s FLOWSA python package. You can see we flag the specific dataset in the USEEIO model spec file here. That file can be downloaded from EPA’s Data Commons:
https://dmap-data-commons-ord.s3.amazonaws.com/flowsa/FlowBySector/GHG_national_2019_m1_v1.3.1_d680131.parquet

These are in a .parquet data type format which are essentially compressed csv files. These can be read in python or R, for example, if you have the useeior package:

f <- 'flowsa/FlowBySector/GHG_national_2019_m1_v1.3.1_d680131.parquet'
file <- useeior:::loadDataCommonsfile(f)
df <- as.data.frame(arrow::read_parquet(file))
