- Individual Impact
- Combine Impact
Global sales of electric cars accelerated fast in 2020, rising by 43% to more than 3m.
Hybrid cars can reduce carbon dioxide emissions by 4.6–7.9 gigatons by 2050, saving owners US$3.0-6.1 trillion in fuel and operating costs over the lifetime of the cars.
Project Drawdown, Hybrid cars
If electric car ownership rises to 16–23 percent of total passenger km at a first cost of $4.7–6.0 trillion, by 2050, 11.9–15.7 gigatons of carbon dioxide from fuel combustion could be avoided as well as US$15.3–21.8 trillion in fuel costs.

Impact metric calculations
To determine the carbon emission reduction estimates related to switching to an electric car or hybrid car, the following calculations were performed:
(Fossil fuel car; kg CO2e/month) – (Lower emitting car; kg CO2e/month)
Fossil fuel car:
(miles/week) / (miles/gallon) x (kg CO2e/gallon) x (weeks/month) = kg CO2e / month
Lower emitting car (electric or hybrid):
(miles/week) x (kg CO2e/mile) x (weeks/month) = kg CO2e / month
