Available Data

Flow-By-Activity and Flow-By-Sector datasets can be accessed without running any FLOWSA methods in Python, by instead accessing EPA's Data Common server. It is recommended to download data with the most recent "Last Modified" date and newest version number.

Instructions for reading a parquet file in Python are found here and an explanation of why we save the data as parquet files is found here.

Flow Classes

Class	Description	FlowBySector Reference Unit	Flow Types
Chemicals	Chemicals and groups of chemicals as defined in the Federal Elementary Flow List	kg	Modeled as ELEMENTARY_FLOWS produced by sectors
Employment	Jobs	p	Modeled as ELEMENTARY_FLOWS produced by sectors
Energy	Energy consumption, transfer as electricity or waste heat	MJ	All types
Geological	Mineral and metal use	kg	All types
Land	Land area occupied	m2	Modeled as ELEMENTARY_FLOWS consumed by sectors
Money	Purchases	USDyear*	Modeled as TECHNOSPHERE_FLOWS with producing and consuming sectors

Other	Misc flows used for supporting data	varies	All types

*USD unit value varies by year and is reported like 'USD2012'

Flow-By-Activity Datasets

Source data are imported and formatted into FlowByActivity datasets. The source data are only modified to meet column formatting criteria, meaning units are not standardized across "Class" types.
