- Manufacturing a cellphone uses approximately 1390 MJ of energy and produces 60 kg of CO2 emissions
- A gallon of gasoline has 131 MJ of energy and emits 8.8 kg of CO2
- Manufacturing a cellphone uses as much energy as 10.5 gallons of gasoline and emits as much as 6.8 gallons of gasoline
- Using a cellphone for a year on average uses 4,221 MJ of energy (equivalent to 32 gallons of gasoline) and emits 112 kg of CO2 (equivalent to 12.8 gallons of gasoline)
- replacing a cellphone every 2 years rather than one would save 30 kg of CO2 emissions (about 3.3 gallons worth) and 700 MJ
