One of the main arguments in favor of electric cars is their lower emissions of environmentally harmful substances. Until now, the practical impact of this effect was unknown, but new research seems to point to a positive future.

A study conducted by a team of scientists at the University of California, Berkeley, shows that: A steady decline in carbon dioxide emissions in the San Francisco Bay area. There was an annual decline of 1.8% between 2018 and 2022, with the mass adoption of electric cars in the region identified as one of the main factors responsible for the index.

Because according to the survey; Direct emissions of pollutants from vehicles decreased by 2.6% per year. The region where cities such as San Jose and San Francisco are located is very suitable for this type of study because almost 40% of new car registrations in the region in 2023 were electric vehicles.

Sustainable goal still far away

Achieved through research 50 sensors were installed in the area to measure air pollution. Equipment has the ability to separate even the most harmful substances present and therefore also find out what the sources of emissions are.

In this way, scientists were able to isolate emission levels from refineries, homes (especially heating systems), industries and vehicles.

In addition to the adoption of fully electric cars, greater sales of hybrid vehicles and the adoption of less harmful fossil fuel consumption systems by conventional cars are also seen by the team as reasons for the decline.

On the other hand, the study also shows that the rate of reduction in emissions is increasing. Still not enough for district to meet goal for entire state of CaliforniaThis means that these pollutants will reach zero by 2045. According to the researchers, in order to achieve the target “smoothly”, the annual decline must be 3.7% per year.

Additionally, the pollution caused by electric cars needs to be taken into account, especially in the process of removing, producing and disposing of batteries from these cars.

There is high adoption of electric vehicles in the San Francisco Bay.

Professor Ronald Cohen, chemical expert and responsible for sensors, is optimistic about the decline in pollutants and celebrates the current rates, as the beginning of the reduction appears to be the most complex period.

He also states: Satellites could do the job of sensors in the future in a more precise and complete way, but such technology is far from being realized.
