CDP Climate Change 2022 Reporting Guidance

(C-EU7.1b) Break down your total gross global Scope 1 emissions from electric utilities value chain activities by greenhouse gas type.

Question dependencies

This question only appears if you select “Yes” in response to C7.1

Change from last year

No change

Rationale

Electric utilities face significant exposure from the transition to a zero-carbon economy through their global greenhouse gas emissions, either directly through electric utility companies’ own energy use for production, or indirectly through combustion of fossil fuels. Electricity production is responsible for of the world’s GHG production. Electric utilities are therefore requested to provide gross emissions for their emission sources by greenhouse gas from sources including fugitive, combustion and other emission sources.

Requested content

General

• This question requests emissions data only from emission sources that fall within the chosen reporting boundary (i.e. Scope 1 emissions) and that are within the electric utilities sector boundary.
• Utility companies that purchase wholesale electricity supplied by independent power producers for resale to their customers should consider reporting these emissions under Scope 3.
• When providing emissions resulting from combustion activities please note for the purposes of this question combustion is divided into three categories comprising electric utilities, gas utilities, and other.
• Emissions not elsewhere classified includes any emissions occurring in the organizational/sector boundary that have not been reported in the above rows. Therefore, the sum of GHG emissions in all rows should equal the figure reported in C-CE7.4/C-CH7.4/C-CO7.4/C-EU7.4/C-MM7.4/C-OG7.4/C-ST7.4/C-TO7.4/C-TS7.4.
• The Global Warming Potential (GWP) factors used here should be consistent with your disclosures throughout the questionnaire. CDP encourages the use of the most recent GWP factors published by IPCC, in alignment with the GHG Protocol.
• Negative numbers are not allowed as you are requested to report gross, not net figures.
• Emissions figures should be for the reporting year only (as defined by your answer to C0.2).

Emissions sources (column 1)

• An explanation of the emissions categories is provided in the explanation of terms.

Gross Scope 1 CO₂ emissions (metric tons CO₂) (column 2)

• Report your organization’s Scope 1 CO₂ emissions for the emissions category in column 1.

Gross Scope 1 methane emissions (metric tons CH₄) (column 3)

• Report your organization’s Scope 1 methane emissions in CH₄ for the emissions category in column 1.

Gross Scope 1 SF₆ emissions (metric tons SF₆) (column 4)

• Report your organization’s Scope 1 sulphur hexafluoride emissions in SF₆ for the emissions category in column 1.

Total gross Scope 1 emissions (metric tons CO₂e) (column 5)

• Total greenhouse gas emissions – from CO₂, CH_4, SF₆ and any other greenhouse gases such as HFC’s etc., if applicable, should be aggregated and reported in units of CO₂e.

Note on sector boundary

Sector production activities relate to activities conducted by your organization relating to the high-intensity sector that this sector-specific questionnaire relates to. These activities may be directly or indirectly related to the production process itself. Given the potential complexity of production sectors, CDP encourages you to identify and remove specific activities from your organizational boundary (or business division’s organizational boundary) that are not necessarily a part of the sector. Starting with your answer to question C6.1, emissions from the following sources should be deducted:

• External corporate entities, i.e. assets, business divisions, partnerships and subsidiaries operating outside of the high-intensity sector.
• Non-industrial buildings, e.g. offices, accommodation, other property.
• Non-production related activities, e.g. management, services, R&D, marketing, retail. o Transport, e.g. distribution, business travel, shipping, freight, logistics.
• Projects, e.g. construction, engineering and maintenance.

Alternatively, you may consider constructing your sector boundary around activities that should be included. At a minimum, you should include in your sector boundary:

• The production processes
• All activities, processes and equipment that are ancillary to the production processes.
• All other industrial installations, energy installations and other installations or activities contributing to or supplying the production processes and ancillary activities, e.g. boilers, power plant, raw material preparation and extraction, etc.
• All buildings that house the production processes and ancillary activities and said installations, as well as buildings used for inventory storage.
• Onsite mobile combustion, e.g. forklifts and excavators, and movement of materials between industrial sites within the sector.
• Any other industrial activities that typically occur on the production sites of the high-intensity sector.

Explanation of terms

• Combustion: Combustion refers to combustion within the company’s boundary giving rise to greenhouse gas emissions. Sources may include boilers, heaters, furnaces, incinerators, internal combustion engines, and turbines. Scope 1 GHG emissions exclude emissions of CO₂ arising from the combustion and fermentation of biomass and biofuels; these emissions are reported as a separate category.
• Fugitives: Comprises all intentional or unintentional releases of carbon dioxide (CO₂) methane (CH₄) and other greenhouse gases. The primary sources of these emissions may include fugitive equipment leaks, evaporation losses, venting, flaring and accidental releases. Further examples of leak sources include valves, fittings, flanges, compressor seals, other compressor related leaks, heaters, dehydrators, and pipelines. Accidental fugitive emissions can be individually found and fixed in order to make the emissions near zero. Emissions from non-point sources, such as wastewater treatment and surface impoundments, should be accounted for under fugitive emissions.
