Nomenclature of GHG emissions



Categories of emissions

The ISO 14064-1 standard (version 2018) distinguishes six categories of emissions:

  1. Direct emissions,
  2. Indirect emissions related to energy,
  3. Indirect emissions associated with transportation,
  4. Indirect emissions associated with purchased products,
  5. Indirect emissions associated with sold products,
  6. Other indirect GHG emissions.

Each category includes several GHG emission sources considered as sub-categories.

  Category Examples of emission sources
Direct GHG emissions

1.1 Direct emissions from stationary combustion sources

Consumption of fuels (heating oil, wood, natural gas in a boiler)
1.2 Direct emissions from mobile combustion sources Fuel consumption in cars, heavy-duty vehicles, or other machinery
1.3 Direct process emissions, excluding energy Industrial processes other than combustion
1.4 Direct fugitive emissions Leaks of refrigerant fluids, methane from anaerobic decomposition of waste, nitrous oxide during fertiliser application
1.5 Emissions from biomass (soil and forests) Sealing off meadows or forests for urban development needs (roads, parking lots, buildings, etc.), deforestation for converting an area (from the organisational boundary into agricultural land)
Indirect emissions associated with energy 2.1 Indirect emissions related to electricity consumption Electricity generation by a power plant - thermal, nuclear, or renewable energy
2.2 Indirect emissions related to the consumption of energy other than electricity Operation of turbines or boilers
Indirect emissions associated with transport 3.1 Upstream transport of goods Transportation of goods by truck, train, ship, airplane, electric-assisted bicycle, etc., with costs borne by the Legal Entity
3.2 Downstream transport of goods Transportation of goods by truck, train, ship, airplane, electric-assisted bicycle, etc., with costs not borne by the Legal Entity
3.3 Home-to-work travel Car, public transportation, motorised two-wheeler, electric-assisted bicycle, etc., used by the employee to travel to work
3.4 Travel of visitors and clients Airplane, train, rental car, taxi, electric-assisted bicycle, etc., or urban public transportation used by the visitor or client to travel to one of the facilities
3.5 Professional travel Airplane, train, rental car, taxi, electric-assisted bicycle, etc., or urban public transportation used for business travel
Indirect emissions associated with purchased products 4.1 Purchases of goods Extraction (or cultivation) and then processing of materials for the production of non-durable products purchased by the Legal Entity: raw materials for production, paper, various supplies, etc.
4.2 Capital goods Extraction (or cultivation) and then processing of materials for the production of non-durable products purchased by the Legal Entity: buildings and other infrastructures, vehicles, machines, computer equipment, etc.
4.3 Waste management Collection and treatment (incineration, composting, landfill, recycling, etc.) of waste and effluents from within the organisational boundary
4.4 Upstream leasing assets Production, use, maintenance, end-of-life of goods (vehicles, housing, machinery) that are leased by the Legal Entity from third parties who own them
4.5 Purchases of services Activities leading to the production of a service (banking, advertising, consulting, technical study, etc.) purchased by the Legal Entity
Indirect emissions associated with sold products 5.1 Use of sold products

Production of energy and materials consumed over the lifetime of products sold during the reporting year by the Legal Entity

5.2 Downstream leasing assets

Production, usage, maintenance, end-of-life of goods  (vehicles, housing, machinery) owned by the Legal Entity and leased to third parties who use them

5.3 End of life of sold products

Collection and treatment (incineration, composting, landfill, recycling, etc.) at the end of life of products sold during the reporting year by the Legal Entity

5.4 Investments

Activities and projects financed by the Legal Entity

Other indirect emissions

Other indirect emissions

Sources of indirect emissions stemming from the activities of the Legal Entity that cannot be accounted for in any of the other categories
