Environmental-Economic Mapping

Earth-Economy Mapping

Below is a Sankey plot showing the mapping of ecosystem services (dependencies) as inputs into the economic production of NAICS industry classifications. Then NAICS codes then map into the emissions by-products (impacts) from their production. This illustrates a general sense of the mapping of the environmental dependencies and impacts of economic production.

Heuristics-Based Mapping

We implement a deterministic Python rule to map ecosystem service inputs into NAICS codes and then NAICS codes into emission byproducts. The output of this product can be foudn in: naics_mapping.xlsx.

The heuristic workflow is:

  1. Read the NAICS sheet with 2022 NAICS codes and titles.
  2. Build ecosystem-service code candidates from the Quarto taxonomy in Ecosystem Services:
  • Provisioning mapped as SEEA 1.x and SEEA CF
  • Regulating mapped as SEEA 2.x,
  • And non-material mapped as SEEA 3.x and SEEA 4.1.
  1. Build emissions code candidates from the Quarto taxonomy in Emissions:
  • Scope 1 for direct activity-linked emissions,
  • Scope 2 for purchased energy-related indirect emissions,
  • And Scope 3 for upstream and downstream value-chain emissions.
  1. Apply layered rules per row:
  • NAICS prefix rules,
  • Then title keyword rules,
  • Then de-duplication while preserving insertion order.

This mapping requires expert review to refine the inital mapping procedure. The most robust method would be to improve on the heuristic classification. But idonsycratic decisions can be inserted though the logic will be left to the expert reviewer and absent from the coding structure.
