CDP Climate Change 2022 Reporting Guidance

(C8.2c) State how much fuel in MWh your organization has consumed (excluding feedstocks) by fuel type.

Question dependencies

This question only appears if you select “Consumption of fuel (excluding feedstock)” in C8.2. For each fuel application selected in C8.2b a column appears in the table in addition to the “MWh fuel consumed for self-generation of heat” and “Total MWh consumed by the organization” columns. If no fuel application is selected in C8.2b then only the “Total MWh consumed by the organization” column will appear.

Change from last year

Modified question

Rationale

Scope 1 greenhouse gas emissions are directly associated with the consumption of fuel for energy purposes. This question provides data users with more transparency regarding the type of fuel an organization has consumed. Total consumption of fuels and their consumption for different energy applications also provides insight on the way in which fuels are used by the organization, which can allow for a fairer and more consistent understanding of corporate energy and emissions from data users.

Requested content

General

• Complete all the cells within the table. Do not leave blanks.
• Figures you provide should be for the reporting year only (as defined by your answer to C0.2).
• You should provide information for all fuel (excluding feedstocks) consumed by your organization in the reporting year. Therefore, the sum of all rows for column 3 (total MWh consumed by the organization) should equal the total consumption of fuel (excluding feedstock) in MWh (from renewable and non-renewable sources) as reported in C8.2a.
• Fuel consumed for generation is fuel consumed for ‘self-generation’. Self-generation means generation from inside the organizational boundary. This includes all generation plant owned or controlled by the organization. Do not provide information for fuel consumed by another organization for the generation of electricity, steam, heat, and cooling that your organization has purchased or acquired.
• This table is for gross fuel consumption data only. You should not provide net consumption nor deduct for energy produced and exported from the organizational boundary. Because feedstock fuels are excluded from this question, this approach should not lead to double counting.
• All fuel consumed inside the organizational boundary should be included, regardless of whether the fuel was purchased or produced by the organization. If a fuel is consumed as a feedstock for the production of another fuel, then the feedstock should not be included, but combustion of the produced fuel should be included. Ultimately, if a fuel is combusted, e.g. consumed for energy purposes and not as a feedstock, then it should be included (see "Explanation of terms" for more detail).
• Companies who consume fuel for electricity, steam, and/ or cooling applications and who consume fuel for other applications (i.e. transportation, industrial process plant and equipment etc.) should report the MWh of fuel consumed for these other applications in column 5 ‘MWh fuel consumed for self-generation of heat’.
• If you do not have exact consumption data, you may alternatively estimate your company’s consumption by reviewing fuel and energy purchasing orders.
• If your raw data is in energy units other than MWh, such as Giga-Joules (GJ) or British Thermal Units (Btu), then you should convert to MWh. For example, 1 Giga-Joule (GJ) = 0.277778 MWh, so if your data is in GJ then should multiply your data by 0.277778. If your data is in million Btu, then you should multiply your data by 0.29307.
• If your raw data is in volume units, e.g. cubic feet or gallons, or in mass units, e.g. kilograms (kg) or pounds (lb), then you should convert to energy units using fuel heating/calorific values. These are available from numerous sources, some of which are listed below:

- IPCC Guidelines for National GHG Inventories (Volume 2, Table 1.2, p1.18-1.19)
- EPA AP-42 (Annex A)
- IEA Statistics Manual (Annex 3, p180-183)
- API Compendium (Table 3-8, p3.20-3.21)

• Further guidance on unit conversion is available in the following Technical Note: “Conversion of fuel data to MWh” and a glossary of definitions on some fuels is provided in Technical Notes: “Fuel Definitions”.
• If you want to provide additional information on the methods or assumptions used to determine the breakdown of fuel consumed for the self-generation of electricity/heat/steam/cooling/self-cogeneration or self-trigeneration then please do so in the Comment column.

Fuels (excluding feedstocks) (column 1)

• Please refer to the CDP Technical note on Biofuels for guidance on biomass/biofuel sustainability. If you report information in the “Sustainable biomass” row, provide the criteria used to classify the biomass as sustainable (e.g. certification) in the “Comment” column (column 9).
• “Other renewable fuels” and “Other non-renewable fuels” are aggregations of any other renewable and non-renewable fuels you consume that do not fit within the categories of fuels listed.
• If you have not consumed any fuels within a category in the reporting year, select a heating value and then enter 0 in the subsequent columns.

Heating value (column 2)

• Fuel should be reported consistently in either LHV or HHV.
• Your choice of HHV or LHV should be consistent with your choice in C8.2a.
• Higher heating value (HHV) is also known as gross calorific value (GCV), and lower heating value (LHV) is also known as net calorific value (NCV). Typically, LHV/HHV ratio is 0.95 for solid and liquid hydrocarbon fuels, such as coal and oil, and 0.9 for gaseous hydrocarbon fuels, such as natural gas.
• Fuel energy data in HHV is typically used in the United States and Canada, whereas LHV is more commonly the unit used in other countries and by international bodies. If you do not know the unit applicable to your raw data, you may wish to infer it based on the location from which the data is sourced, i.e. if the fuel related data is sourced from outside of the United States and Canada, then it is likely that LHV is applicable.

Total MWh fuel consumed by the organization (column 3)

• Enter the total fuel in MWh consumed by your organization in the reporting year for the category of fuel in column 1. It should be equal to the sum of fuel consumed for the self-generation of electricity, heat, cooling, steam and/or cogeneration or trigeneration.

MWh fuel consumed for self-generation of electricity (column 4)

• Enter in MWh the total consumption of fuel within the category in column 1 for the self-generation of electricity.
• Make sure that you do not enter data for the actual electricity generated from these fuels. This table is for the consumption of the fuels themselves and aims to capture the energy content of the initial fuel used, not the energy content of the electricity generated from these fuels.

MWh fuel consumed for self-generation of heat (column 5)

• This column will be presented if you selected “Yes” for any fuel application in C8.2b except if you selected only “Consumption of fuel for the generation of heat”. This is because combustion reactions are exothermic and thus generate heat in addition to any secondary energy carrier generated (electricity, steam, and/or cooling).
• This column is not presented if only “Consumption of fuel for the generation of heat” is selected in C8.2b, because in this case the “MWh fuel consumed for self-generation of heat” will be equal to the “Total fuel MWh consumed by the organization”.
• Enter in MWh the total consumption of fuel within the category in column 1 for the self-generation of heat.
• Fuel consumed for heat is fuel that is combusted for the direct use of the heat/thermal energy its combustion releases.
• This heat is used in applications such as direct heating for industrial process plant and equipment, engines, turbines, furnaces, heaters, stoves, incinerators, kilns, dryers, thermal oxidizers, space heating, open burning, flaring, or any other combustion that is not for the generation of secondary energy carriers (electricity, steam, and/or cooling).
• Do not enter the heat delivered for the application. This question asks for fuel energy, which is the total heat of fuel combustion and is equal to the heating value (or calorific value) of the fuels themselves.

MWh fuel consumed for self-generation of steam (column 6)

• Enter in MWh the total consumption of fuel within the category in column 1 for the self-generation of steam. This excludes fuel consumed for steam generated in cogeneration or trigeneration plant.

MWh fuel consumed for self-generation of cooling (column 7)

• Enter in MWh the total consumption of fuel within the category in column 1 for the self-generation of cooling. This excludes fuel consumed for cooling generated in cogeneration or trigeneration plant.

MWh fuel consumed for self-cogeneration or self-trigeneration (column 8)

• Enter in MWh the total consumption of fuel within the category in column 1 for self-cogeneration or self-trigeneration.

Comment (column 9) (optional)

• Any further information about the data provided may be entered here.
• For example, you may comment on the specific fuels consumed within each category in column 1.
• If you report information in the “Sustainable biomass” row, provide the criteria used to classify the biomass as sustainable (e.g. certification).

Explanation of terms

• Excluding feedstocks: Fuels consumed as feedstocks are fuels that are not combusted for energy purposes. For example, naphtha and ethane are feedstocks that may be converted into petrochemical products such as ethylene, and should not be included. The steel industry is a special case because coke and fuel injectants consumed at the blast furnace serve as feedstocks and a source of energy. These fuels are considered feedstocks and should not be counted. However, all fuels consumed for energy, i.e. combusted, that are derived from fuel feedstocks, e.g. blast furnace gas, coke oven gas, and smelting reduction gas, should be counted. Companies that consume fuel as feedstocks will have the opportunity to disclose these fuels in sector specific questions.
• Heating Value: Lower heating value (LHV) and Higher heating value (HHV), also known as net calorific value (NCV) and gross calorific value (GCV) respectively, are different measures of heat energy released from fuel combustion. Figures measured in HHV are larger because HHV includes the latent heat of water vaporization from combustion, whereas LHV does not. The difference between LHV and HHV is related to the fuel’s hydrogen content.
• Biomass: any organic matter, i.e. biological material, available on a renewable basis. Includes feedstock derived from animals or plants, such as wood and agricultural crops, and organic waste from municipal and industrial sources. Biomass fuels should be sustainably sourced and certified where possible, and include:

- Solid biofuels - solid fuels derived from biomass. Includes feedstock derived from animals or plants, such as wood and agricultural crops, and organic waste from municipal and industrial sources.
- Biogas - a mixture of methane (CH4) and carbon dioxide (CO2) used as fuel and produced by bacterial degradation of organic matter or through gasification of biomass.
- Liquid biofuels - liquid fuels derived from biomass such as ethanol and biodiesel.
