'According to Miao, approximately 42 of the 123 auto manufacturers operating in China will not meet their credit requirements without changing their product mix and will be forced to buy credits. '
'As shown in Table 1, most of the EVs sold in China are low-cost A0 (sub-compact) and A class (compact) vehicles, and their performance level barely meets government standards.'
'The price of charging in Beijing is fixed at 0.8 yuan/kWh, and the price of electricity in residential areas fluctuates with the time of day, ranging from 0.4 to 1.0 yuan/kWh. All these prices are subsidized.'

'Since the GHG emission intensity of the power sector differs from one region to another, we estimate the provincial average emission rate of Beijing (983 g-CO2eq/kWh), Shanghai (809 g-CO2eq/kWh), and Guangdong (687 g-CO2eq/kWh), where EVs are relatively more popular, due to their access to inexpensive hydro-electricity.'

'when EVs replace ICEVs, our lifecycle estimates of reduction of GHG emissions is reduced by approximately 36% due to GHG emissions from the manufacturing sector, especially battery manufacturing. '

'Despite the higher GHG emissions in the manufacturing phase, EVs can help reduce the GHG emissions from the transportation sector by up to 6.2% in 2030 with a 20% penetration rate, assuming the carbon intensity of regional power grids continues to improve.'

'In summary, our two main conclusions are 1) EV deployment may increase GHG emissions in some regions, but these increases will be offset by declines in the emissions in other regions, so that the national average impact will be slightly lower GHG emissions, and 2) On a life cycle basis, EVs reduce emissions relative to ICEVs, and this reduction will be higher if battery production facilities are able to invest in cleaner technologies and improved processes, and vehicle recycling rates improve.'
