Many people spend their lives estimating embedded emissions and, more importantly, the time it will take for any emission-reducing technology (e.g. electric cars) to amortise away the CO2e emissions required to produce it.
For instance, it's been estimated that a Tesla Model 3 "needs to be driven for 13,500 miles (21,725 km) before it does less harm to the environment than a Toyota Corolla" [1]
