API

• .asNumber() - get the kg CO2e as a number
• .measure(interval) - calculate the emissions every two seconds and prints the result to the console. (The default value of interval is 2000ms)
• .measureOnce() - the same as .measure but it does it only once.

Formula

Carbon Footprint (kg CO2e) = MB * 0.5 kg CO2e/MB
