Electric vehicles versus ICEs, hybrids and hydrogen?

Producing an electric vehicle’s battery emits c9T of CO2. Hence, EVs will ultimately have c50% lower emissions than gasoline vehicles, assuming equivalent c8-10 year lifespans. But it takes around 3.5 years and c50,000 miles for the EV to ‘repay’ the CO2-costs of producing its battery. This data-file presents the calculations.
