Energy Use & GHG 2025
General Introduction
Energy production and energy use are the largest man-made sources of air pollution and greenhouse-gas (GHG) emissions. The operational, environmental, and financial impacts of energy are key issues for facility operations. Driving energy efficiency and use of renewable energy throughout facility operations is an important area of focus for all factories.
As climate change emerges as the most severe human, environmental, and economic risk in the world, more stringent requirements and regulations may be imposed by governments. If your facility reduces your energy consumption and greenhouse gas emissions, it will help to reduce your exposure to regulatory risks or new requirements from brands. This may also create an economic advantage for your company by mitigating risk of fossil fuel and energy cost increase.
In general, the Higg FEM Energy and GHG section encourages you to:
- Identify and understand the types of energy used at your facility.
- Understand what operations and processes at your facility use the most energy.
- Track and report the quantity of energy consumption at your facility.
- Calculate Scope 1, 2, and 3 GHG emissions.
- Evaluate, plan for, and adopt solutions to reduce energy use and GHG emissions through better manufacturing practices and energy management.
- Implement leading practices to reduce energy use and GHG emissions. (e.g., phase out the use of coal and fossil fuels for cleaner/renewable energy solutions).
Additional details on the intent and criteria for each Higg FEM Energy and GHG question is provided in the guidance below along with useful technical guidance and resources to support your facility in the management and reduction of energy and GHG.
Energy Use in Your Factory
Energy is used throughout manufacturing facilities for various operational and production activities. The Higg FEM requires that facilities track and report energy use data for the energy sources listed below, which are grouped into three categories (Purchased, Renewable, and Non-Renewable Energy).
Additional requirements on reporting energy data in the Higg FEM including any specific exclusions are provided in the relevant Higg FEM question guidance below.
| Purchased Energy | Renewable Energy | Non-Renewable Energy |
| Purchased Electricity Purchased Steam Purchased Chilled Water Purchased Heating (District Heating) |
Biodiesel Biogas Geothermal Hydro Mini or Micro-Hydro (onsite) Purchased Renewables Solar Photovoltaic (electricity)(onsite) Solar Thermal (onsite) Wind (onsite) |
CNG – Compressed Natural Gas Coal – commercial mix (1) Coal Water Slurry (2) Diesel Fabric Waste Fuel Oil – Blended (3) LNG – Liquid Natural Gas LPG – Liquid Petroleum Gas Natural Gas Petrol/ Gasoline Liquid Propane |
Biomass
- Biomass – Sustainably sourced with certification. (4)
- Biomass – Without sustainably sourced biomass certification. (5)
Notes:
- Coal – commercial mix includes all types of traditional coal (e.g., anthracite, bituminous, etc.)
- Coal Water Slurry is a combustible mixture of fine coal particles suspended in water used as fuel source.
- Fuel Oil – Blended includes all types of fuel oils (e.g., furnace oil, bunker fuel, etc.)
- Biomass – Sustainably sourced with certification is any biomass that has supporting certification documentation from a sustainably sourced biomass program (e.g., Forest Stewardship Council (FSC), Programme for the Endorsement of Forest Certification (PEFC), ISCC Biomass Certification, Sustainable Biomass Program (SBP) Certification, Better Biomass Certification, Country Specific Certification, etc.)
- Biomass – Without sustainably sourced biomass certification is any biomass that is not certified through a sustainably sourced biomass program.
Domestic and Production Energy Use
The Higg FEM, energy use is categorized as domestic or production energy use which are defined as follows:
Domestic Energy Use – Energy that is consumed in non-production related areas and/or buildings such as employee washrooms, domestic only wastewater treatment plant, or office areas separated from production, canteen and kitchen, security posts, external lighting (e.g. roadway or landscape lighting), medical center, etc.
Production Energy Use – Energy that is directly or indirectly consumed in production related activities or production areas such as production equipment operations, onsite energy generations for production (e.g. steam or electricity), industrial wastewater treatment plant, production area lighting, heating, ventilation and cooling, etc.
Note: If industrial and domestic wastewater are treated together, energy use of the combined wastewater treatment plant should be included in production energy use.
Greenhouse Gas (GHG) Emissions in the Higg FEM
Greenhouse gases (GHGs) are gases in the Earth’s atmosphere that absorb/trap some of the Earth’s outgoing radiation, maintaining the earth’s temperature (called the ‘greenhouse effect’). Anthropogenic GHGs, or GHGs emitted due to human activity, are causing the planet to warm faster than natural climatic variations, and this is called global warming or climate change. Energy generation and use, transportation, use of refrigeration gases, and other activities produce greenhouse gas emissions that harm the environment. Reference IPCC: www.ipcc.ch
GHG emissions are categorized into 3 different scopes:
- Scope 1 Emissions: Direct emissions from owned or controlled sources.
- Scope 2 Emissions: Indirect emissions from the generation of purchased energy consumed.
- Scope 3 Emissions: All other indirect emissions that occur in a company’s value chain.
The Higg FEM calculates Scope 1 and 2 GHG emissions based on the energy use values entered in the Energy section, as well as the refrigerant use listed in the Air section. Energy use values input into the FEM are converted to a common unit (MJ) and GHG emissions (CO2e) are calculated using the 100-year Global Warming Potential factors for each GHG in the IPCC 6th assessment report, including non-carbon GHGs.
In the FEM, location based emission factors are used by default when market-based emission factors are not provided by the user or required to be input into the FEM. Location-based and market-based emission factors are defined as follows:
- Location-based emission factors use the average emission factor for the energy/emission source (e.g. regional or national emission factors)
- Market-based emission factors consider contractual arrangements under which the organization procures power from specific sources (e.g. fossil fuels, renewable). These emission factors are typically specified in Energy Attribute Certificates (EACs), contracts such as a power purchase agreement (PPA), to purchase electricity from a specified generating facility, or provided as Supplier-Specific Emission Factors.
Additional information on the Higg FEM GHG emissions calculation methodology can be found on the howtohigg.org website here: https://howtohigg.cascale.org/resources-library/resources-library-fem-4-0-resources/
Reporting Energy Use in the FEM for Purchased Electricity, Purchased Renewables, Onsite Renewables and EACs
The following provides guidance on how to report, purchased electricity, purchased renewables, onsite renewables and relevant EACs in the FEM:
Notes on EACs and PPAs:
-
Energy Attribute Certificates (EACs) is a general term for a variety of market-based instruments that represent how energy is generated and ownership of the attributes of that energy. EACs are certificates that represent the renewable energy attributes of a unit of electricity. They can be purchased separately from the electricity itself. The name and specific requirements for EACs are typically defined by the jurisdiction or program under which they are issued. EACs can be issued as part of government initiatives or be offered by independent third-party providers
-
Power Purchase Agreement (PPAs) are contracts in which a company agrees to purchase electricity from an energy provider (e.g., renewable energy project), typically for a defined period of time and cost.
-
In general, PPAs and EACs are both used to source renewable energy, however they work in different ways. These are reported separately in the Higg FEM to track the different types of instruments a facility uses to demonstrate renewable energy use.
Scenario 1
How Purchased Electricity should be reported if Purchased Renewables are also purchased through a PPA by the facility
The facility should report their Purchased renewables and answer the relevant sub questions under purchased renewables category.
If the facility purchases grid electricity in addition to purchased renewables, the additional grid electricity purchased should be reported under Purchased electricity.
Example: Facility A uses 100 MWh of Electricity within the facility, out of which 60MWh is from Purchased renewables connected to a PPA, and the remaining 40MWh is directly taken from the Electricity service provider without any renewable attributes.
The Facility should report their electricity consumption as below,
- Purchased Electricity = 40,000 kWh
- Purchased Renewables = 60,000 kWh
Scenario 2
How Purchased Electricity should be reported if EACs are also purchased and retired from an external party without any power purchase agreement for purchase of renewable electricity.
The facility should report their Purchased electricity under purchased electricity category.
The annual quantity of EACs purchased and retired under the facility name will need to be reported under the separate question on purchase of Energy Attribute certificates.
No deduction or addition of electricity usage is required in this situation.
Example: Facility B uses 100 MWh of Electricity within the facility, and also purchased and retired 40MWh of EACs.
The Facility should report their electricity consumption as below,
- Purchased Electricity = 100,000 kWh
- Report 40 MWh under the EAC question.
Note: The facility should NOT report any quantity under Purchased Renewables.
Scenario 3
How Purchased Electricity should be reported if Purchased Renewables are also purchased through a PPA by the facility, and the relevant EACs for the purchased renewables are also retired under the facility name.
The facility should report their Purchased electricity under purchased electricity category.
The facility should report their Purchased renewables and answer the relevant sub questions under purchased renewables category.
Since the EACs for the purchased renewables are also retired under the facility name, the facility should answer “Yes” to the sub question on ownership of the purchased renewables.
The Higg FEM has now accounted for both the Purchased Electricity and the Purchased Renewables.
The associated EACs of the Purchased Renewables should NOT be reported under the EAC question as the consumption and GHG reduction have already been considered when reporting both the consumption information.
Example: Facility C uses 100 MWh of Electricity within the facility, out of which 60MWh is from Purchased renewables connected to a PPA and associated EACs are also retired under the facility name, and the remaining 40MWh is directly taken from the Electricity service provider without any renewable attributes.
The Facility should report their electricity consumption as below,
- Purchased Electricity = 40,000 kWh
- Purchased Renewables = 60,000 kWh
Note: The facility should NOT report any EACs under the EAC question.
Scenario 4
How Purchased Electricity should be reported if Purchased Renewables are also purchased through a PPA by the facility, and additional EACs are purchased and retired under the facility name to offset the associated Scope 2 emissions from purchased electricity..
The facility should report their Purchased electricity under purchased electricity category.
The facility should report their Purchased renewables and answer the relevant sub questions under purchased renewables category.
The PPA should state that the ownership of the Renewable Energy or associated GHG Offsets are also transferred to the facility when purchasing the purchased renewables, if so, the facility should answer “Yes” to the sub question on ownership of the purchased renewables.
The Higg FEM has now accounted for both the Purchased Electricity and the Purchased Renewables.
The additional EACs purchased and retired under the facility name should be reported under the EAC question.
Example: Facility D uses 100 MWh of Electricity within the facility, out of which 60MWh is from Purchased renewables connected to a PPA and additional EACs are retired under the facility name for the remaining 40MWh that the facility purchases from the electricity service provider.
The Facility should report the their electricity consumption as below,
- Purchased Electricity = 40,000 kWh
- Purchased Renewables = 60,000 kWh
- In this case, The facility should report the 40MWh of EACs under the EAC question.
Note: No deduction or addition of electricity usage is required in this situation, the facilities GHG emissions will be calculated by the system, taking into consideration the GHG emissions from purchased electricity , the purchased renewables and the GHG reduction credits relevant for the purchased and retired EACs.
Scenario 5
How Purchased Electricity should be reported if a facility generates onsite renewable electricity and sells it to the grid without using it onsite, but registers the onsite renewable electricity under an EAC scheme and retires it under the facility name.
The facility should report their Purchased electricity under purchased electricity category.
The facility should NOT report the onsite generated renewable electricity under any of the onsite renewable electricity categories.
The EACs registered and retired under the facility name should be reported under the EAC question.
Example: Facility E uses 100 MWh of Purchased Electricity within the facility, and generates 20MWh of onsite solar PV electricity and exports the renewable electricity to the grid, while registering the onsite renewable electricity under an EAC scheme and retires them under the facility name,
The Facility should report their electricity consumption as below,
- Purchased Electricity = 100,000 kWh
- In this case, the facility should report the 20MWh of EACs under the EAC question.
Note: The facility should NOT report any consumption under Onsite Solar PV or deduct any electricity consumption from the purchased electricity.
Scenario 6
How Purchased Electricity should be reported if a facility generates onsite renewable electricity and uses it onsite, and also registers the onsite renewable electricity under an EAC scheme and retires it under the facility name.
The facility should report their Purchased electricity under purchased electricity category.
The facility should report the onsite generated renewable electricity under the relevant onsite renewable electricity categories.
The EACs registered and retired under the facility name should NOT be reported under the EAC question.
Example: Facility F uses 100 MWh of Purchased Electricity within the facility, and generates 20MWh of onsite solar PV electricity and uses it onsite, also while registering the onsite renewable electricity under an EAC scheme and retires them under the facility name,
The Facility should report their electricity consumption as below,
- Purchased Electricity = 100,000 kWh
- Onsite Solar PV = 20,000kWh
- Also indicate within the sub question for onsite solar PV that the facility has not sold the EACs to an external party.
Note: In this case, The facility should NOT report the 20MWh of EACs under the EAC question.
Scenario 7
How Purchased Electricity should be reported if a facility generates onsite renewable electricity and uses it onsite, and also registers the onsite renewable electricity under an EAC scheme and sells it to another organization which retires the credits under their name.
The facility should report their Purchased electricity under purchased electricity category.
The facility should report the onsite generated renewable electricity under the relevant onsite renewable electricity categories., also report whether the credits were sold to an external party and the relevant percentage of EACs sold to that party in the sub questions posted to the facility.
The facility should not report the EACs under the EAC question.
Example: Facility G uses 100 MWh of Purchased Electricity within the facility, and generates 20MWh of onsite solar PV electricity and uses it onsite, also it registered the onsite renewable electricity under an EAC scheme and sells EACs relevant for 15MWh to Facility H which retires them under Facility H. and the remaining 5MWh is retired under the Facility G.
The Facility should report their electricity consumption as below,
- Purchased Electricity = 100,000 kWh
- Onsite Solar PV = 20,000kWh
- Also indicate within the sub question for onsite solar PV that the facility has sold 75% of the EACs to an external party.
Note: In this case, The facility should NOT report the 20MWh of EACs under the EAC question, or even the 5MWh EACs that it retired under its own name.
Energy Data Quality
Accurately tracking and reporting energy use data over time provides facilities and stakeholders with detailed insight into opportunities for improvement. If data is not accurate, this limits the ability to understand the facility’s energy use footprint and identify the specific actions that will help reduce environmental impacts and drive efficiencies.
When establishing an energy tracking and reporting program, the following principles should be applied:
- Completeness – The tracking and reporting program should include all relevant sources (as listed in the FEM). Sources should not be excluded from data tracking and reporting should be based on materiality (e.g., small quantity exceptions).
- Accuracy – Ensure that the data input into the energy tracking program is accurate and is derived from credible sources (e.g., calibrated meters, established scientific measurement principles or engineering estimates, etc.)
- Consistency – Use consistent methodologies to track energy data that allows for comparisons of energy use over time. If there are any changes in the tracking methods, energy sources, or other operations that impact energy use data, this should be documented.
- Transparency – All data sources (e.g., energy bills, meter readings, etc.), assumptions used (e.g., estimation techniques), and calculation methodologies should be disclosed in data inventories and be readily verifiable via documented records and supporting evidence.
- Data Quality Management – Quality assurance activities (internal or external) should be defined and performed on energy data as well as the processes used to collect and track data to ensure reported data is accurate. For additional guidance on managing data quality, refer to Chapter 7 of the GHG Protocol a Corporate Accounting and Reporting Standard: Managing Inventory Quality.
The above principles are adapted from The Greenhouse Gas Protocol – Chapter 1: GHG Accounting and Reporting Principles (https://ghgprotocol.org/)
