原文是英文 我大概归纳一下重点
1. 原本Obama的政策是每年逐渐升高排放标准的限制，Trump希望到2020年先冻结住
2. Trump想要收回各州能够各自订立排放标准的权力，要将标准一致化
3. CA是反抗最大的一州 (毫无意外)XDDD
4. 多数制造商，包括美国本土制造商都认为这一政策会打乱目前的整体规划
5. 当年Obama的政策在当下是引起很大的反弹，然而随着近几年EV快速发展，制造商们
反而没那么反对Obama的排程。
Ford CEO/董事长甚至直接宣布他们支持Obama到2025之前的排放规划
心得:
1. 这其实并没有让GM/Ford等等美国品牌制造商更好过，因为他们头早就都洗下去了
2. 受益的其实是传统燃油车零件供应商以及某部分能源供应商 当然我想这也是目标
3. 受益的还有UAW，UAW立场一向都很鲜明XDD
4. Musk之前杠上Trump我觉得多多少少也有差
5. 这场仗没那么好打，因为可能会牵涉到联邦法院、释宪、自治权等等
所以议题不仅仅只有排放标准这件事情，牵涉到更多联邦政府管辖范围
CA带头出来，可能会有其他18个州出来反对
6. 这个政策伤害对于制造商伤害是全面性的，不管日欧美系车都遭殃
他们所有的长期计画会被迫延后。
原文内容：
The Trump administration has published plans to weaken regulations for
vehicle fuel efficiency and carbon dioxide emissions, raising fears in the US
automotive industry of a crippling clash over standards between Washington
and the state of California.
The US Environmental Protection Agency and the National Highway Traffic
Safety Administration announced on Thursday that they favoured freezing
standards at 2020 levels, rather than requiring the steady increase in
performance planned under the Obama administration between 2021 and 2026.
As part of the announcement, Washington also proposed stripping California of
its rights to set its own vehicle emissions standards and to require
manufacturers to sell electric cars and trucks in the US’ richest and most
populous state.
The proposals set the stage for a legal battle over the future of the
automotive industry, threatening to create uncertainty that could drag on for
years, affecting decisions over investment plans and the development of new
models.
Xavier Becerra, California’s attorney-general, said on Twitter that the
Trump administration had “launched a brazen attack” on the country’s clean
car standards. He pledged that his department would “use every legal tool at
its disposal to defend today’s national standards and reaffirm the facts and
science behind them”.
California signed up to the Obama administration’s plans in 2011, and state
officials still want to impose standards that become more stringent over
time. They have signalled they could reach a compromise to ease the burden on
manufacturers, but pledged to fight the administration through the courts if
it tries to impose standards the state finds unacceptable.
The Auto Alliance and Global Automakers, two industry groups that between
them represent all large carmakers selling in the US, issued a joint
statement saying they supported “continued improvements in fuel economy”.
They added that they also support standards with flexibility to allow “
balancing priorities like affordability, safety, jobs and the environment”.
They suggested the administration’s favoured option should be seen as a
startingoint, and urged the federal government and California to “find a
common-sense solution that sets continued increases in vehicle efficiency
standards while also meeting the needs of America’s drivers.”
The US automotive industry has been urging a rethink of the Obama-era
standards. Shortly after Donald Trump’s inauguration, the chief executives
of 18 of the largest manufacturers in the US, including Ford, General Motors,
Toyota and Volkswagen, wrote to the new president warning him that the
regulations put up to a million jobs in the industry at risk.
More recently, however, industry leaders have sounded less antagonistic
towards the Obama-era plans. Bill Ford and Jim Hackett, the chairman and
chief executive of Ford, wrote in March:劬e support increasing clean car
standards through 2025 and are not asking for a rollback.”
