U.S. Environmental Protection Agency (EPA) and the California Air Resources Board, the two main regulators of vehicle emissions in the United States are taking assistance to shape policy from Argonne’s Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) model. this model includes various parameters to measure the environmental impact of Electric vehicles; their study includes from a battery of Ev to plastic or steel materials used in EV cars. Principal energy systems analyst at Argonne - Jarod Cory Kelly stated EVs produce more carbon than combustion engine vehicles, mainly due to the processing & extraction of EV battery minerals & power cell productions.

The Reuters analysis has selected the above-mentioned model for the hotcake topic of late, whether ElectricVehicles are more environment friendly than gasoline cars or not. Reuters Analysis showed that a mid-sized EV saloon production produces 47 grams of carbon dioxide per mile, or more than 8.1M grams before reaching the 1st user. However, when comparing, a similar gasoline car produces 32 grams per mile or more than 5.5M grams. In addition, a senior scientist & director of the Systems Assessment Center at Argonne's Energy Systems Division - Michael Wang, said that EVs generally produce far less carbon over a 12-year lifetime.

Even in worst cases where an electric car is charged only from a coal-fired grid, it would emit an extra 4.1M grams of carbon a year, while a gasoline vehicle would generate over 4.6M grams. The result of Reuters analysis is similar to the life-cycle assessment of combustion-engine & electric cars in Europe by research group - IHS Markit. According to its director of carbon dioxide compliance - Vijay Subramanian, the study showed the actual break-even point in carbon emissions for electric cars was around 15,000 to 20,000 miles, depending on the country. He added using such a method showed there were long-term merits from changing to EVs.

 

In 2019, University of Liege researcher Damien Ernst said that EV's CO2 emission can occur once the car travels 7000,000 km. But recently he overlapped his comment and said that EV can emit CO2 traveling between 67,000 km and 151,000 km. Few groups continue to argue that EVs are not necessarily greener than fossil-fuelled vehicles. The US Petroleum Institute, which represents about 600 firms in the oil industry, said: "Multiple kinds of research showed that, on a life-cycle basis, different automobile powertrains result in similar greenhouse gas generations."
