EV vs combustion car CO2 comparison API

Compare annual use-phase CO2e of an electric vehicle (annualKm x kWh/100km / 100 x grid intensity) against a combustion car (annualKm x L/100km / 100 x fuel factor) over N years. Returns each vehicle's annual and total kg CO2e, the kg saved, the reduction percent, which is cleaner, and tree equivalents saved. Answers 'is an EV cleaner than my gas car','how much CO2 does switching to an EV save','EV emissions on a dirty grid','5-year EV vs ICE footprint'.
