Carbon Footprint Calculator for ASEAN SMEs

The Carbon Footprint Calculator has been designed to help ASEAN SMEs measure their corporate emission footprint following GHG Protocol Guidance, including direct emissions from fuel and processes (Scope 1 emissions) and those emissions from purchased electricity (or Scope 2 emissions) for the assets they operate.

The following tool is not a complete evaluation of an organizational footprint. It only includes selected emission sources, common to the majority of SMEs using an operational control approach.

Data Requirements

In order to calculate your organisation’s carbon footprint, you will need the following information:

Fuel consumption

Fuel consumed by the organisation in its sites and owned vehicles. This can be natural gas, diesel or LPG. You may find this information in bills, fuel card data or meters.

Energy consumption

Electricity used in your sites. You may find this information through meter readings, utility bills, or automatic meter readings.

Top ups made to air conditioning and refrigeration units

Many refrigeration, fire protection and air conditioning equipment contain a type of F gas (Fluorinated greenhouse gas), which has a large carbon footprint. Please include the type and quantity of top up that has been done during the reporting year, as this serves as an indication of the amount of refrigerant leakage. You may contact your air conditioning or refrigeration provider for such information.

It is important that the reported data covers the annual consumption for your organisation. If you do not have data exactly for the whole year, you should estimate the annual consumption using the average energy or fuel consumed per month i.e., average monthly value consumed × 12 months.

Instructions

  1. Select the activity: Select an activity type from the dropdown. If in doubt, select an activity and move to ‘Step 2: Select the fuel type’ to see a list of fuel type under the selected activity.
    • a. Process – direct fuel combustion
    • b. Vehicle Fleet – tailpipe emissions from vehicles owned by the company
    • c. Fugitive – refrigerant leakage from air-conditioning and refrigeration units
  2. Select the fuel type: Select the fuel type representative of the fuel consumed by your organisation.
  3. Fill in the amount of fuel used: Fill in the amount of fuel used, in annual basis, and ensure that it is in the correct units as shown under fuel type. You may find this information in bills, fuel card data or meters.
  4. To add/remove entries: If there are multiple entries of activities and/or fuel type, click on the green button (‘+’ sign) on the right to add an additional entry i.e., repeat Step 1 to 3. If you need to remove an entry, click on the red button (‘-‘ sign).
  5. Select country: Select the country or region which your organisation is in. This will ensure that the most relevant grid emission intensity is used to calculate your organisation’s emissions.
  6. Fill in amount of electricity consumed: Fill in the electricity consumed in kWh. You may find this information through meter readings, utility bills, or automatic meter readings.
