GHG organizational reporting


The term "organization" is understood to refer to:

  • Companies
  • Public institutions and the State
  • Local/regional authorities (collectivities) producing the inventory of their specific activity (also known as "Patrimony & Competences")

To conduct an organization's GHG assessment, it is necessary to define:

  • the main stages of the process
  • the boundaries to be taken into account
  • the data to be used

The formulated recommendations are not intended to take the place of the regulatory or normative requirements when these are applicable, nor of the environmental policies of the organizations or their expertise in these matters.



These are presented on this page: stages



The question of boundaries is essential since this is what determines the framework of the GHG assessment. What installations or buildings are to be taken into account? How far to go with the data collection?


General principle (ref.: ISO 14 064-1 standard)

The implementation of an Organization GHG assessment requires the definition of the organizational boundary of the study: "What installations are concerned by my study?" The organization, whatever the complexity of its structure, may in fact be responsible for, control or be involved in the activities of different installations. Any installation may include one or more GHG sinks and/or sources.

Once this organizational boundary is determined, the organization must define its reporting boundary: "What are the sources generating emissions within my organizational boundary?"

Organizational boundary

This involves defining the sites, installations and competences included in the inventory.

For this, the ISO 14064-1 standard defines 2 modes of consolidation:

  • The "capital share" approach: the organization consolidates the emissions for installations in line with its capital share in the installations.
  • The "control" approach

The "control" approach breaks down into:

  • Financial control: the organization consolidates 100% of the emissions for the installations over which it exercises financial control.
  • Operational control: the organization consolidates 100% of the emissions for the installations over which it exercises control.

The international financial reporting standards (IFRS) define "control" as "the power to direct the financial and operational policies of an entity in order to benefit from its activities".

If the organization owns and operates all of its installations, then the organizational boundary is identical whatever the mode of consolidation chosen.

If the organization is joint owner of installations, then the mode of consolidation chosen will influence the result of the inventory.

Each approach has its pros and cons.

"Organizations should comply with the organizational boundary already defined for their general accounting, provided that this boundary is clearly laid out and used consistently. When applying these concepts, the underlying hypothesis of the "primacy of substance over form" should be pursued. In other words, GHG emissions and removals should be quantified and declared in accordance with the concrete and economic reality of the organization, and not simply according to its legal status". (ISO 14064-1: 2006, Appendix A).

Reporting boundary

This involves defining the sources of emissions to be included in the inventory.

The reporting boundary corresponds to the emission categories and subcategorizations linked to the activities of the organizational boundary. The principal international standards and methods define 3 emission categories:

  • Direct GHG emissions (or SCOPE 1): Direct emissions emanating from stationary or mobile installations situated within the organizational boundary, i.e.: emissions from sources owned or controlled by the organization, such as combustion from stationary and mobile sources, industrial processes excluding combustion, emissions from ruminants, biogas from landfill centers, refrigerant leakages, nitrogenous fertilizers, biomass, etc.
  • Indirect energy emissions (or SCOPE 2): Indirect emissions associated with the production of electricity, heat or steam imported for the activities of the organization.
  • Other indirect emissions (or SCOPE 3): The other emissions indirectly produced by the activities of the organization which are not accounted for under Scope 2 but which are linked to the overall value chain, such as: the purchasing of raw materials, services or other products; employee travel; upstream and downstream transportation of goods; the management of waste generated by the activities of the organization; the use and end-of-life of sold products and services; the amortization of production goods and equipment, etc.

Subcategorization of emissions

Drawing on the work of reference standards currently being drafted (ISO-TR 14069: Application guide for standard 14064-1 WD3, March 2011), it is possible to distinguish several emission subcategories in each emission scope. These subcategories, along with the calculation methodologies, are presented in the "Method for carrying out GHG emission assessment in accordance with article 75 of Act No. 2010-788 of 12/07/2010" and the aforementioned normative reference frameworks.

The 3 SCOPES are then broken down into 23 subcategories (ISO-TR 14069: Application guide for standard 14064-1 WD3, March 2011).

Scopes No. Categories


Direct GHG emissions

1 Direct emissions from fixed combustion sources
2 Direct emissions from mobile sources with internal combustion engines
3 Direct emissions from processes excluding energy
4 Direct fugitive emissions
5 Emissions from the biomass (soils and forests)


Indirect emissions associated with energy

6 Indirect emissions linked to electricity consumption
7 Indirect emissions linked to the consumption of steam, heating or refrigeration


Other indirect GHG emissions

8 Emissions linked to energy not included in the "direct GHG emissions" and "indirect GHG energy emissions" scopes
9 Purchasing of products and services
10 Amortization of assets
11 Waste
12 Upstream goods transportation
13 Professional travel
14 Uptream leasing assets
15 Investments
16 Transportation of visitors and clients
17 Downstream transport of goods
18 Use of sold products
19 End-of-life of sold products
20 Downstream franchise
21 Downstream leasing
22 Home-work commuting
23 Other indirect emissions

The selection of the scope of study depends on the desired target of the assessment (environmental policy of the organization, regulatory requirements, carbon vulnerability, etc.), as well as on the available resources of the organization for carrying out the GHG inventory and implementing the relevant actions.


Data to be used

To implement a GHG assessment, it is necessary to gather all the activity data for the organization being studied. This may concern information that is already available within the organization (primary data), but also external data to be collected from suppliers, customers, users, etc., or indeed statistical or study data (generic or secondary data).

These are the data that can be used for completing the spreadsheets for the chosen method. These data will then be associated with an emission factor enabling calculation of its carbon equivalent. These emission factors are available in the Base Carbone®.
