Airsourceinvent

Has your facility created an inventory of all point source air emissions sources at your facility? (Ref ID: airsourceinvent)

Answer Yes if: Your facility has a documented inventory of all point source emission sources at your facility including point sources from facility operations and production emission sources.

Notes:

  • Air Conditioning units are not considered a point source emission source in the FEM. These are considered fugitive emission sources.

If you select Yes, you will be asked the following sub question(s):

  • Does your facility’s point source air emissions inventory include the following information? Select all that apply.
    • Unique source identifier (emission point name or number)
    • Process or Equipment the source is linked to
    • List of pollutants emitted from the source
    • Control devices installed on the source, if applicable
      • Note: The intent of this inventory item is to indicate the presence or absence of a control device for the source. If there is no control device for this source and this is indicated on the inventory, this option should be selected.
  • Please upload a copy of the inventory

Suggested Uploads:

  • A copy of the facilities inventory of point source air emission sources.

What is the intent of the question?

The intent of this question is for facilities to establish an inventory (i.e. a list) of all possible point sources of emissions to air on-site. This includes point sources from facility operations and production emissions. The intent is also for facilities to understand which pollutants are emitted or have the potential to be emitted from each point source.

Technical Guidance

An air emission source inventory is needed for facilities to identify, track, and manage emission sources onsite. To prepare a comprehensive inventory, all point sources of facility emissions from operations and production should be included. Regular review should be carried out to make sure the inventory is up-to-date and accurate. This inventory should include emissions sources regulated by permits as well as those not currently regulated.

Emission source inventories can contain varying levels of detail and information, however the following basic information should be included in the inventory 

  • Unique source identifier (emission point name or number)
  • Process or Equipment the source is linked to.
  • List of pollutants emitted from the source.
  • Legal or other emissions testing or reporting requirements if required (testing parameters and frequency), if applicable
  • Control devices installed on the source, if applicable
    • Note: The intent of this inventory item is to indicate the presence or absence of a control device for the source. If there is no control device for this source and this is indicated on the inventory, this option should be selected.

An example inventory can be downloaded here: https://www.sumerra.com/wp-content/uploads/Air-Emissions-Inventory.xlsx

Examples of common sources of emission sources and pollutants that can be emitted through point sources are provided below. Note that this is not an exhaustive list and facilities may require the support of qualified environmental experts to identify air emission point sources and all potential pollutants emitted.

  • Particulate Matter (PM) – e.g., from fuel combustion, yarn spinning, slashing, weaving, synthetic fiber manufacturing, casting
  • Oxides of Sulphur and Nitrogen (SOx and NOx) – typically associated with fuel combustion.
  • Volatile organic compounds (VOCs) – e.g., from fabric finishes, solvents, adhesives, fabric printing, tenterframes, degreasing operations.
  • Ozone depleting substances (ODS) – commonly found in refrigerants, many apparel spot cleaners, and some adhesives and solvents.
  • Ammonia (NH3) – e.g., from fabric finishing, tanning processes.
  • Ozone (O3) – e.g., from denim finishing
  • Carbon disulfide (CS2) – from Man-Made Cellulosic Fibres (MMCF) Production
  • Hydrogen Sulfide (H2S) - from Man-Made Cellulosic Fibres (MMCF) Production
  • Hazardous or toxic air pollutants (HAPs/TAPs) - e.g., from fuel combustion, solvents, adhesives, and finishing processes (e.g., printing, potassium permanganate spray), anti-fungal/bacterial agents, metal plating, injection moulding, etc. 

Country-specific regulation may define which air pollutants are designated as HAPs/TAPs within a specific jurisdiction. Where country-specific definitions or regulations do not define HAPs/TAPs, recognized lists from other jurisdictions may be referenced when determining if pollutants from facility operation are considered HAPs/TAPs.  For example, information on HAPs from the US EPA can be found here https://www.epa.gov/haps. A current list of HAPs (as defined by the US EPA can be found here: https://www.epa.gov/haps/initial-list-hazardous-air-pollutants-modifications

The intent of this question is to ensure that facilities are operating in compliance with all applicable legal requirements relating to air emissions including any permitting, reporting, and testing requirements.  

Technical Guidance

Aspects related to air emissions at facilities may be regulated in multiple ways depending on several factors such as the type(s) of emission sources, pollutants, industry category, or the jurisdiction in which the facility operates. 

Requirements may include:

  • Discharge permits or approvals for facility emissions to air or specific facility operations or equipment.
  • Source testing (also known as stack testing) of specific sources at frequencies defined by local law(s) to determine compliance with in-stack or emission rate concentrations of specific pollutants (e.g., ppm or mg/m3)
  • Calculating or measuring annualized mass emission quantities of specific pollutants to demonstrate compliance with permits or other regulatory requirements (e.g., tons or kg per year) 
  • Calculating the offsite concentration of specific pollutants using air dispersion modelling to demonstrate compliance with ambient air quality guidelines or standards.
  • Legally mandated control devices for emission sources. 

Being in compliance means that all legally required permits are valid and up to date and any testing and/or reporting are performed in accordance with all applicable legal requirements.

Technical Guidance

Refrigerants such as CFCs and HCFCs commonly used in air conditioning, cooling and refrigeration equipment can contain ODS that are contributors to GHG emissions and climate change due to their relatively high global warming potentials (GWPs). Refrigerants are often emitted to the air through equipment leaks or during servicing or disposal of refrigerant containing equipment.

Knowing which refrigerants are used onsite will help facilities plan for phasing out the use of ozone depleting substances (ODS) at their facility in accordance with good environmental practices and current or future regulatory requirements. More information on phasing out Ozone Depleting Substances can be found here: https://www.epa.gov/ods-phaseout

Airleakage

Does your facility have preventative maintenance procedures in place to avoid refrigerant leakage from your equipment?  (Ref ID: airleakage)

Answer Yes if: Your facility has a documented preventative maintenance program that covers all refrigerant containing equipment at your facility.

If you answer Yes, you will be asked the following sub questions:

  • Please upload your preventative maintenance procedures.
  • If you can't upload your procedures, please describe them here.

Suggested Uploads

  • Copies of your preventative maintenance plan or program documentation that covers all refrigerant containing equipment at your facility (e.g., preventative maintenance schedules or procedures, completed inspection checklists or service records, etc.) 

What is the intent of the question?

The intent of this question is to ensure that facilities have preventive maintenance procedures in place to proactively identify and minimize the release of refrigerant gases to the environment.  

Technical Guidance

Preventative maintenance is maintenance that is regularly scheduled and performed on equipment to reduce the chances of equipment failure and identify potential problems before they result in breakdowns or leaks. Preventive maintenance should be planned and scheduled based on available information for each piece of equipment (e.g., manufacturer’s recommendations, past breakdowns or leaks from equipment, operating conditions, etc.) 

Refrigerants are commonly emitted to the air through equipment leaks and although leaks do occur, preventative maintenance can help facilities prevent or detect leaks early and minimize releases to the environment. Preventative maintenance actions may include:

  • Inspecting compressor operation
  • Checking refrigerant levels
  • Refrigerant leak testing
  • Inspecting motor operation and motor mounts
  • Checking electrical connections
  • Inspecting all pipes and fittings
  • Examining all other parts for wear and tear
  • Testing and recalibrate temperature settings and thermometers.
  • Cleaning the equipment (e.g., motors, fans, cooling coils, drain lines, etc.)
  • Note - Inspection and maintenance of refrigerant containing devices should only be conducted by trained and qualified individuals.

Resources:

Additional resources for inspecting, maintaining, and managing refrigerant containing equipment are provided below.

Note - The resources are provided for reference only and may contain legal references that do not apply to your facility. Facilities are expected to understand and comply with any applicable local regulations related to the use and management of refrigerants.

Guidance for Higg FEM:

Note: Refrigerants used within owned and operated vehicles will be in scope of the Higg FEM from Higg FEM 2024 onwards. Facilities are encouraged to account and report these sources and emissions in FEM 2023. If these are not tracked in FEM2023, a "Yes" response can be input for Question 6 "Does your facility track refrigerant usage?". However, if these sources are not tracked from FEM2024 onwards, facilities should select "Partial Yes" or "No"to this question in accordance with FEM Guidance for this question.

If you answer Yes or Partial Yes, you will be asked the following sub questions:

  • Refrigerant (list of refrigerants will pre-populate based on refrigerants used)
  • Did you add this refrigerant to existing equipment in the reporting year?
  • Quantity of refrigerant added to existing equipment during the reporting year
  • Unit of measure
  • What method was used to track refrigerant use?
  • Did you fix the leak associated with this refrigerant?
  • How did you fix the leak/ What is your plan for fixing this leak?
  • Please upload your action plan or methods fixing the leak that you had fixed the leak

What is the intent of the question?

The intent of this question is for facilities to enter quantitative data that shows how much refrigerant(s) your facility emitted in the reporting year. 

Note: This question will contribute to your GHG-emissions calculation so it’s important for you to enter accurate data about refrigerant use onsite. 

Technical Guidance

Refrigerants are often emitted through equipment leaks and servicing. Most modern equipment is designed to minimize leaks however over time, leaks do occur. Having to add refrigerants to existing equipment generally indicates the system has a leak.

Tracking refrigerant use is an important part of managing refrigerants use onsite. Tracking refrigerant use allows facilities to monitor how much refrigerant has been released to the environment as well as identify problematic or leaking equipment.  

It is also important to have an action plan to fix the leaks and/or upgrade equipment to eliminate refrigerant leakage.

When establishing your tracking and reporting program, start by doing the following:

  • Map out all facility equipment (production and operational equipment) to identify equipment that contain refrigerants.
    • This should include identifying the specific refrigerant type that is used in the equipment (e.g., R-22).
  • Establish procedures to determine how much refrigerant is released (e.g., through leaks, disposal, etc) from each piece of equipment. 
    • In general, the amount of refrigerant released is equal to the amount of refrigerant that is added to the equipment (see Calculating Leak Rate below) 
    • Refrigerant purchase invoices, or service records may also be helpful in determining quantities released.
    • If estimation techniques are used, the calculation methodology should be clearly defined and be supported by verifiable data.
  • Record tracking data (e.g., monthly, annual leakage or top-up records) in a format that is easy to review [e.g., spreadsheet or similar data analytics program that allows export of data in a human readable format (e.g., Microsoft Excel)] and maintain relevant supporting evidence for review during verification.

Reporting Refrigerant Data in the FEM:

Before reporting refrigerant data in the FEM, data quality checks should be performed to ensure that the data AND the processes used to collect and record the data are effective at producing accurate energy data.

Do:

  • Review source data (e.g., equipment maintenance records, servicing logs, refrigerant purchase invoices, etc.) against aggregated totals to ensure it is accurate. 
  • Ensure the most recent and updated versions of data tracking spreadsheets are being used and that all automated calculations/formulas are correct.
  • Ensure the proper units are reported and verify any unit conversions from source data to reported data.
  • Review any assumption or estimation methodology/calculations to ensure accuracy.
  • Report the proper tracking method in the FEM (e.g., measured, leakage rate, estimate)

Do Not:

  • Report data that is not accurate (e.g., the data source is unknown or has not been verified).
  • Report estimated data if it is not supported by verifiable and reasonably accurate estimation methodology and data (e.g., leakage rate or other engineering calculations).

Airrefrigtrack Verification And Scoring

How This Will Be Verified:

When verifying a facility’s refrigerant data, Verifiers must review all aspects of the facility’s tracking program that could produce inaccuracies including:

  • The initial data collection processes and data sources (e.g., equipment maintenance records, servicing logs, refrigerant purchase invoices, etc.); and
  • The process and tools used to aggregate the data (e.g., spreadsheet calculations, leakage rate calculations, etc.)

If any inconsistencies or errors are noted, the reported information must be corrected where possible and detailed comments should be included in the Verification Data field.

Full Points

Documentation Required: 

  • All refrigerant containing equipment has a log of equipment servicing including refrigerant replacement that is kept up to date (e.g., monthly, annual leakage rates or top-up records)
  • Records of the quantity of each refrigerant added to existing equipment for the reporting year.
  • Documentation of the methodology used to track refrigerant use (e.g., leakage rate or other consumption calculations and methodology) 
  • Documented plans or actions taken to fix refrigerant leaks, if applicable.

Note: If the facilities equipment is maintained by third-party service providers, copies of relevant documentation (e.g., service records, maintenance logs, quantities of refrigerants added) should be made available for verification. 

Interview Questions to Ask: 

  • Staff responsible for maintaining the refrigeration equipment and tracking usage should understand and be able to describe the process and frequency for tracking refrigerant and the methodology to determine refrigerant usage. 

Inspection - Things to Physically Look For: 

  • Evidence the facility is tracking refrigerant use and this is consistent with onsite observations (e.g. service tags or record on equipment that match maintenance records)

Partial Points: 

  • Partial points will be awarded if your facility tracks the usage of at least one (1) refrigerant but does not yet track all refrigerants used onsite.

Airmonitor

Are you monitoring or reporting against any industry guidelines or tools for air emissions (additional to the legal requirement)?  (Ref ID : airmonitor)

Answer Yes if: You are monitoring or reporting your facility’s air emissions against industry guidelines or tools for air emissions. The standard must be in addition to any local law monitoring or reporting requirements.

Answer Not Applicable if your facility does not have any relevant emission from operational or production sources that are covered under industry guidelines or tools (i.e., if your facility only has refrigerant emissions)

Note: If your facility is only monitoring, reporting, or testing your facility emissions in accordance with local law requirements, you should select No for this question.

If you answer Yes, you will be asked the following sub questions:

  • Please indicate which Air standard you are reporting against:
    • ZDHC Air Position Paper/Guideline
    • ZDHC MMCF Air Guidelines
    • Other
  • If other, please describe.

Suggested Uploads

  • Copies of emissions calculations or reporting that demonstrate facility emissions are being monitored or reported against the selected standards.

Note: This question is unscored in Level 1. Scoring will be applied in Level 2 and will result in additional scored questions on industry air emission guidelines/tools in Level 2. 

What is the intent of the question?

The intent of this question is to encourage facilities to monitor and report their air emissions against industry developed guidance or tools that go beyond basic legal compliance monitoring and reporting.  

Technical Guidance

Industry guidance and tools are developed to support facilities in the proper management and reduction of emissions to the environment. These tools intend to provide consistent methodologies to identify, monitor and report emissions of hazardous pollutants. They also strive to support facilities in managing and reducing emissions by establishing progressive emission thresholds that go beyond basic compliance. 

Different guidelines or tools may have different requirements for monitoring and reporting of air emissions (e.g., the type and frequency of emission reporting, types of pollutants that must be monitored/reported, emission calculation or testing methodologies, etc.) When adopting an industry standard, facilities should review the guideline to determine the monitoring and reporting requirements that apply to their operations and put in place procedures to meet the required monitoring and reporting requirements. 

Examples of industry guidance/tools for air emissions are the ZDHC Air Position Paper/Guidelines and the ZDHC MMCF Air Guidelines - Air Emissions of the ZDHC MMCF Guidelines.  Both of these guidance documents can be found and downloaded here https://www.roadmaptozero.com/output
