How each country is on track to meet its obligations under the Paris Agreement can be constantly monitored online (via the Climate Action Tracker [95] and the climate clock). President Obama was able to formally enshrine the United States in the agreement through executive measures because he did not impose new legal obligations on the country. The United States already has a number of instruments on the books, under laws already passed by Congress to reduce carbon pollution. The country officially joined the agreement in September 2016, after submitting its request for participation. The Paris Agreement was only able to enter into force after the formal accession of at least 55 nations representing at least 55% of global emissions. This happened on October 5, 2016 and the agreement came into force 30 days later, on November 4, 2016. The development of e-mobility creates real opportunities for improved air quality. Consistent measures in the area of transport electrification should be implemented in parallel with the liquidation of low-emission emissions from the combustion of solid fuels in domestic systems and the promotion of the switch to electric heating. This is reflected in the fact that some of the instruments applicable to pollution are common from both sources. Therefore, improving air quality through the development of e-mobility will have an impact not only on improving public health (reducing health care costs), but also on reducing damage to the natural environment and buildings.

Another factor that has a positive impact on health is the reduction of traffic noise in cities. Unfavourable health symptoms are already observed at 55 dB in cases of long-term exposure to noise, and in some larger cities, noise levels are even higher. The development of e-mobility will go a long way to reducing traffic noise. Taking part in an election campaign promise, Trump – a climate denier who has claimed that climate change is a „hoax“ perpetrated by China, announced in June 2017 his intention to withdraw the United States from the Paris Agreement. But despite the rose garden president`s statement that „we`re going out,“ it`s not that simple. The withdrawal procedure requires that the agreement be in effect for three years before a country can formally announce its intention to withdraw.
