CO2 estimates are calculated as follows: Laptop manufacture typically produces 225 kg of CO2; and shipping adds 25 kg of CO2. The energy consumed
during three years’ laptop use produces around 50 kg of CO2. The CO2 estimate for the second shipping, typically for a shorter distance than the first,
includes the carbon footprint of the refurbishing process.
