GHG, Labor, and other Environmental Footprints By Sector

The MRIO documents the embodied impacts as well as upstream sectoral and resource dependencies for a number of goods (sectors).

• Scope 1 coefficients report, for every one unit ($1) of a good or service sold, the direct intensity of how much of various nonmonetary factors were used to produce that output, e.g. CO₂ emitted, land occupied, or labor used, et cetera.
• Scope 2 coefficients report the environmental intensity embodied in purchases from Tier 1 suppliers.
• Scope 3 coefficients, also called indirect intensity coefficients or footprint or Leontief multipliers, report the total factor inputs requried, along all incoming supply chains, to produce that unit of output. This is the total number of labor hours, CO₂ emissions, etc., along the entire production and supply chain that were emitted or used in service of creating that unit of output.

The data at this page provides packages of pre-calculated Scope 1 and Scope 3 multipliers. The units used vary by stressor (CO₂ is expressed in Gg CO₂/$, land in ha/$, etc), and the units are specified in each file.

This page provides Scope 1 and Scope 3 embodied resource multiplier coefficients for several common factors:

• CO₂ - Embodied CO₂ (t per $)
• CO_2-eq - Embodied CO_2-eq (all GHGs) (t per $)
• BlueWater - Embodied water footprint (Mm3/$)
• MonetaryFlows - Monetary value
• VAWages - Embodied wages ($/$)
• VATotal - Embodied value added ($/$)
• EmploymentFTE - Embodied jobs (FTE/$1000)
• Biomass - Embodied biomass (t/$1000)
• AgArea - Embodied agricultural area (ha/$1)
• Forest - Embodied forest area (ha/$1)
• Biodiversity - Number of threatened speces (# species/$1)

Description:

The downloadable file for each country/year contains the following information:

Multipliers
Scope 1 multipliers refer to the direct emisisons associated with $1 of primary production in this industry. These are the emissions or resources used directly by facilities which are part of this sector. (Note: Does not include embodied emissions from electricity.)
Scope 3 multipliers refer to the total emissions, i.e. inclusive of all embodied upstream emissions, required or utilized to produce $1 worth of goods sold by this sector. Includes emissions embodied in electricity and all other purchased inputs to production.
This sheet provides data at the highest level of sectoral detail.
Note: Some countries provide their data in a "Supply/Use Table" framework. For these countries, primary production occurs in Industries but sales are recorded by Commodities. Scope 1 multipliers are associated with Industries and Scope 3 multipliers are associated with Commodities. No direct mapping exists between Industries and Commodities.

Multipliers - E26
This provides the same results as the Multipliers sheet but in the Eora26 Common Classification. This provides a simplified set of data and is advantageous for cross-country comparisons.

Top Upstream Sectors
Breakout of the top upstream sectors involved in creating $1 of output of each commodity in this country.
The sector names are listed first (in columns F:T), followed by the values in a subsequent block.
The values represent embodied resource use. E.g. 3.1459 Kg of CO₂ is emitted by sector X in service of production that ultimately ends up embodied in commodity Y. The units are indicated above.
Top sectors are often domestic.
A separate list of top foreign supplier sectors is also provided in columns further to the right.

Top Upstream Countries
Breakout of the top upstream supplier countries involved in creating $1 of output of each commodity in this country.
The country names are listed first (in columns F:T), followed by the values in a subsequent block.

Top Tier 1 Suppliers
Breakout of the top Scope 2 (aka Tier 1) supplier sectors, ranked according to their embodied emissions. This refers to the commodities directly purchased by companies within the sector in question.

Top Sales Destinations
Breakout of the top destinations where each commodity's output is sold.

Usage Notes

For some sectors and some countries, Scope 1 multipliers may be zero but Scope 3 multipliers are >0. This is because there are zero reported emissions in that sector, but imports used in producing that do carry embodied GHGs.

The units used vary by stressor. Units are specified in each file.

For countries in Full Eora that use Supply/Use tables, the Scope 1 multipliers will be >0 for Industries (since factor inputs are allocated to industries) and the Scope 3 multipliers will be >0 only for Commodities, since the economy utilizes factors of input for industries and emits commodities. Often countries use identical classifications for industries and commodities in their SUTs, but in some cases they do not. In this case you will have to pick the factor that best matches the sector/product you wish to analyse. This does not occur in Eora26 because as part of the Full Eora to Eora26 simplication process all SUT tables are converted to Commodity-by-Commodity IO tables.
