When do electric vehicles become cleaner than
the production of a mid-sized EV saloon generates 47 grams of CO2 per mile during the extraction and
production process. By comparison, a similar gasoline vehicle generates 32 grams per mile

DETROIT (Reuters) - You glide silently out of the Tesla showroom in your sleek new electric Model 3, satisfied
you're looking great and doing your bit for the planet.
But keep going - you'll have to drive another 13,500 miles (21,725 km) before you're doing less harm to the
environment than a gas-guzzling saloon.
That's the result of a Reuters analysis of data from a model that calculates the lifetime emissions of vehicles, a
hotly debated issue that's taking center stage as governments around the world push for greener transport to meet
The model was developed by the Argonne National Laboratory in Chicago and includes thousands of parameters
from the type of metals in an electric vehicle (EV) battery to the amount of aluminum or plastic in a car.
Argonne's Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) model is now
being used with other tools to help shape policy at the U.S. Environmental Protection Agency (EPA) and the
California Air Resources Board, the two main regulators of vehicle emissions in the United States.
Jarod Cory Kelly, the principal energy systems analyst at Argonne, said making EVs generates more carbon than
combustion engine cars, mainly due to the extraction and processing of minerals in EV batteries and production of
the power cells.
