Base data needed for regionalized calculations

Defining Rest-of-the-World locations

Calling the function bw2regionalsetup() creates several new metadatasets.

First, a data file that defines the various Rest-of-the-World locations for ecoinvent 3+ is downloaded, and added to the data store restofworlds. Each Rest-of-the-World dataset has a label like RoW-42, and is defined by the areas which are excluded from its location. For example, RoW-152 excludes Germany, Algeria, the Netherlands, Norway, and Russia. The data format for restofworlds is a dictionary of excluded codes:

{'RoW-152': ['DE', 'DZ', 'NL', 'NO', 'RU']}

In restofworlds, these codes are the ecoinvent shortnames, and there is no distinction between what will later be split into different geocollections.

For more information on Rest-of-the-Worlds, see the ecoinvent geography report and the ecoinvent interactive Rest-of-the-Worlds explorer.

However, it is not enough to have a list of information that could be used to identify each Rest-of-the-Word - we also need to have concrete data on what these locations include. This means that we create a new geocollection "RoW", as well as a topocollection "RoW".

Defining countries

Next, we create a geocollection "world" and topocollection "world". It is quite useful to label countries by their ISO 3166-1 alpha-2 country codes (e.g. “DE” for Germany), so we don’t require these locations to be given a complex location key like ("world", "DE"); instead, we will treat any two letter country code as if it came from the "world" geocollection.

Defining ecoinvent-specific locations

Ecoinvent defines a large number of additional locations, like “Europe” or “Canada without Alberta and Quebec”. See the constructive geometries source repository for more information on ecoinvent-specific locations. These locations are handled in a third new geocollection, "ecoinvent", as well as the "ecoinvent" topocollection.

Intersections

The following intersections are only created if the default pandarus_remote server, https://pandarus.brightwaylca.org, is available.

  • (‘world’, ‘geo-weighted-pop-density’)
  • (‘ecoinvent’, ‘geo-weighted-pop-density’)
  • (‘RoW’, ‘geo-weighted-pop-density’)
