On August 6, according to White House officials, US President Joe Biden will sign a new executive order on Thursday local time to ensure that half of all new cars sold in 2030 are zero emission vehicles. At the same time, Biden will also propose new vehicle emission rules to reduce pollution by 2026 < p > it is reported that Biden will sign an executive order with representatives of Detroit carmakers and the national automobile workers' Federation on Thursday. "These new measures will strengthen the leadership of the United States in the field of zero emission vehicles and trucks by accelerating innovation and manufacturing in the automotive industry, supporting the domestic supply chain of the automotive industry and increasing automotive jobs with generous salaries and benefits," the White House said in a statement < p > Biden's goal is not legally binding, but it has won the support of major automobile manufacturers in the United States and foreign countries. However, stellantis, the parent company of general motors, Ford and Chrysler, said that this positive sales target of electric vehicles can only be achieved through billions of dollars of government incentives. These incentives include providing subsidies to consumers, building electric vehicle charging networks, increasing investment in R & D and expanding support for electric vehicle manufacturing and supply chain in the United States < p > in a joint statement, the three Detroit automakers said that their goal is to "achieve 40% - 50% of the annual sales of electric vehicles in the United States by 2030". Hyundai expressed support for the target of 40% - 50% of electric vehicle sales in 2030. Toyota also said the goal was "very beneficial to the environment" and said it would "do our best". U.S. Transportation Secretary Pete Buttigieg said: "we must take action to electrify half of our new cars within 10 years to meet our emission reduction requirements." < p > among Biden's 50% target and automaker's 40% - 50% target, zero emission vehicles include battery electric vehicles, fuel cell vehicles and plug-in hybrid vehicles. Among them, plug-in hybrid vehicles are also equipped with gasoline engines. Previously, Biden has repeatedly rejected the call of many Democrats to follow the example of California or some countries to set a specific date for phasing out fuel vehicle sales. Dan Becker, head of the non-profit organization "Safe Climate transportation" movement, criticized that Biden's goal "depends on the unenforceable voluntary commitments made by unreliable carmakers" < p > Joe Britton, executive director of the zero emission Transport Association, said: "to do this well, the budget for the next 10 years will be between $20 billion and $30 billion." The association said 4.5 million charging piles would be needed when switching to pure electric vehicles in the United States < p > Biden's new executive order also sets a timetable for the formulation of new emission standards. Light vehicles should formulate new emission standards at least before 2030, and heavy vehicles should formulate new emission standards as early as 2027 < p > meanwhile, U.S. regulators plan to propose revising former president Donald Trump's plan to cut fuel economy standards in March 2020. Trump calls for an average fuel economy increase of 1.5% per year by 2026, which is far lower than the 5% increase set by the Barack Obama administration in 2012. Biden is expected to increase this figure to 3.7% < p > at present, all electric vehicles account for only about 2% of the total automobile sales in the United States, although the sales of electric vehicles have jumped sharply in recent months. According to the data of Kelly blue book, the sales of all electric vehicles in the United States exceeded 100000 in the second quarter of 2021, which was largely driven by Tesla Model 3 and model y. Meanwhile, the sales volume of hybrid vehicles (20000 vehicles) also increased, with a year-on-year increase of 200% < p > in some ways, Tesla has become the kind of carmaker that the Biden administration wants. Tesla only produces electric vehicles, and its CEO Elon Musk's preference for vertical integration means that Tesla's cars are assembled from a large number of parts made in the United States. However, it is strange that Tesla was not invited to the event scheduled for Thursday < p > it was unclear which companies would participate in Thursday's event, and the White House did not immediately respond to a request for comment. However, Elon Musk, CEO of Tesla, wrote on Twitter: "it seems strange that Tesla was not invited." When asked why Tesla was absent, batijig did not comment directly, but said the move to electric vehicles focused on the entire market < p > Biden called on the government to allocate $174 billion to boost the electric vehicle industry, including $100 billion in consumer incentives. An infrastructure bill proposed by both parties in the Senate includes $7.5 billion for the construction of electric vehicle charging stations, but there is no money for new consumer incentives（ Small) < / P > < p >
