ecoinvent_lcia

The point of the ecoinvent LCIA methods is to ste^H^H^Hadapt the hard work of the Ecoinvent Centre, so as to develop LCIA methods and results for ecoinvent LCI that match their own results.

2020-01-11 WARNING: this assumes mass as reference quantity by default, which leads to obvious quantity conversion errors for non-mass-reference indicators like land occupation.

Solution requires access to Ecoinvent metadata in order to determine the reference quantities for flows.

EcoinventLcia

Bases: BasicArchive

Class to import the Ecoinvent LCIA implementation and construct a flow-cf-quantity catalog. The external keys are concatenations of the three

__init__(source, ei_archive=None, ref=None, mass_quantity=None, version=EI_LCIA_VERSION, ns_uuid=EI_LCIA_NSUUID, static=True, **kwargs)

EI_LCIA_VERSION default is presently 3.1 for the spreadsheet named 'LCIA implementation v3.1 2014_08_13.xlsx'

Parameters:

Name	Type	Description	Default
source			required
ei_archive		required to determine reference quantities for flows	None
ref		hard-coded 'local.ecoinvent.[EI_LCIA_VERSION].lcia'; specify at instantiation to override	None
mass_quantity			None
version		default is '3.1'	EI_LCIA_VERSION
ns_uuid		required; default / convention is '46802ca5-8b25-398c-af10-2376adaa4623'	EI_LCIA_NSUUID
static		this archive type is always static	True
kwargs		quiet, upstream	{}
