Carbon Dioxide (CO2) Emission

The Energy Consumption Dashboard in Manage displays Energy Savings, Energy Usage, and its equivalent C02 Emission for the selected period. In the Energy Consumption Dashboard, you can monitor and measure Energy Usage by

  • Energy in kWh,
  • Cost in your regional currency. To set the Electricity cost per your country's norms, refer to the Change Electricity Pricing.
  • CO2  emissions - The CO2 emission values displayed in Energy Consumption is based on the US emission factor value. This value differs by geography and is subject to change.

This article describes the procedure used for calculating CO2 emissions. 

  1. Select a facility in the left panel and click the Energy Consumption tab. 
  2. Select CO2 from the dropdown to display CO2 emissions in the dashboard.

Calculating C02 Emission in Pounds (lbs)

Use the following formula to calculate CO2 emission in pounds:

Energy Saved (KWh) x 0.00068956 x 2204.6 

where 0.00068956 is the CO2 Factor value for the USA. The CO2 Factor value is region and country- specific.

Determining the Energy Consumption in kWh

Since the formula uses energy saved in kWh, the first step is determining the Energy Consumption in kWh value.

  1. Select a facility in the left panel and click the Energy Consumption tab.
  2. Select the duration period.  
  3. Select Energy from the dropdown list.

The graph shows the energy consumed in kWh for the day and time. 

  1. Note the Consumption value that is displayed in the data. For example, on Sunday, at 12 am, the energy consumed is 315.2 kWh.
  2. Substituting the Consumption value in the formula:
    315.2 x 0.00068956 x 2204.6 = 479.16 pounds
    The C02 emission is approximately 479 pounds.

Verifying the CO2 Emission

Go to Energy Consumption and select CO2 from the dropdown list to verify the CO2 emission.

The value of CO2 emitted for the duration is 479 lbs., per the calculation.

Calculating CO2 Emission in Tons

Use the following formula to calculate CO2 emission in tons:

Energy Saved (KWh) x 0.00068956 

where 0.00068956 is the CO2 Factor value for the USA. The CO2 Factor value is region and country- specific.

  1. Select a facility in the left panel and click the Energy Consumption tab.
  2. Select the duration period.  
  3. Select Energy from the dropdown list. 
  4. Note the Period Consumption value that is displayed in the dashboard. For example, the energy consumed from Jan. 1, 2019, to Dec. 31, 2020, the energy consumed is 776.2 kWh.

Substituting the Consumption value in the formula:
776.2 * 0.00068956 = 0.535 tons.
The C02 emission is approximately 0.535 tons.

Go to the Energy Consumption dropdown and select CO2 from the list to verify the calculation.
