The impact of electrification technology on reducing emissions is significant, mainly reflected in the following aspects:
1. Reduce greenhouse gas emissions:
Electric vehicles do not produce exhaust emissions during use, and compared to traditional internal combustion engine vehicles, they can effectively reduce CO2 emissions throughout their entire lifecycle. Research has shown that the reduction rate of carbon dioxide emissions from pure electric vehicles during the fuel cycle compared to traditional gasoline vehicles has increased from 34% (2015) to 57% (2020), and is expected to reach 69% (2030). In addition, the full lifecycle energy consumption of electric vehicles is 1123-1592KJ/km, and the equivalent greenhouse gas emissions of carbon dioxide are 131-162g/km. Compared with gasoline vehicle routes, electric vehicle routes have significant energy-saving and emission reduction advantages, saving more than 35% of energy and reducing emissions by at least 20%.
2. Improving air quality:
The popularization of electric vehicles can significantly reduce urban air pollutants such as particulate matter and carbon monoxide. Due to the fact that electric vehicles do not produce exhaust emissions, promoting electric vehicles can improve urban air quality.
3. Reduce emissions of key precursor pollutants:
Electric vehicles can significantly reduce the emissions of key precursor pollutants such as VOCs and NOx, which are the main factors leading to an increase in PM2.5 concentration. Electrification has significant health benefits for densely populated areas in cities. For example, by 2030, the annual population weighted concentration of PM2.5 in the three major urban agglomerations can be reduced by 0.5 μ g/m3, with a reduction rate of 2% to 3%.
4. Health benefits:
The development of electric vehicles has a positive impact on air quality in China and key regional urban agglomerations, especially in quantitatively evaluating the reduction of major air pollutant concentrations under different electrification scenarios. It was found that in the next decade, the monetization benefits of China's transportation electrification on air quality improvement will be significantly higher than its monetization benefits on greenhouse gas emissions reduction.
5. Collaborative emission reduction effect:
The development of electric vehicles not only reduces CO2 emissions, but also has a synergistic emission reduction effect on air pollutants such as NOx and VOCs. In the case of Jiangsu Province, the emission reduction rate of electric vehicles will reach 17.1% to 49.7% in 2030, and 41.8% to 83.5% in 2060.
In summary, electrification technology has a significant impact on reducing emissions, not only reducing greenhouse gas emissions and improving air quality, but also bringing positive benefits to human health and the ecological environment. With the advancement of technology and the cleanliness of electricity production, the environmental benefits of electrification technology will be further amplified.
