The United States rejoined the Paris accords

After Donald Trump's withdrawal in 2019, America is once again the standard-bearer of efforts to limit damage to our planet. For the United Nations, it is above all a political message that was badly needed

A month ago, on his first day as president, Joe Biden signed an executive order that overturned Donald Trump's provisions on the country's withdrawal from the international agreement on protecting the environment and reducing greenhouse gas emissions, dating back to 2015. Trump's attempt to get the US out of the deal only lasted 107 days. In fact, despite the former president signing his retirement in 2019, the exit was made official only on November 4, 2020, the day after the US elections.

The Paris Agreement is the largest project of alliance between the countries of the world to counter the effects of climate change, signed by 194 nations. The purpose of the agreement is to reduce emissions of gases responsible for the greenhouse effect - mainly from the use of fossil fuels - to almost zero and to limit the increase in the planet's temperature. The agreement also provides that more developed countries provide assistance to developing ones to reduce their environmental impact, without limiting their growth.

Although the return of the United States is mainly symbolic, reports the Guardian, the leaders of the international community expect a deep involvement of the North American country in the fight against the climate crisis, after the largely marginal position taken so far. "We expect the United States to take the lead in global efforts to reduce greenhouse gas emissions to zero," said United Nations Climate Change Convention Secretary General Patricia Espinosa, "including the development of a national greenhouse gas reduction plan. emissions to achieve the 2030 goals ". United Nations Secretary General Antonio Guterres called the US re-entry into the agreement "very important", while former environmental policy officer Christiana Figueres expressed satisfaction with the "political message" given by the Biden administration to the rest of the world.

The UN, in fact, feared that other countries would follow the United States out of the agreement, although fortunately no one has yet. For Figueres, though, while individual North American cities and states have continued to work to reduce emissions, the four-year Trump administration has slowed global efforts towards climate neutrality. “From a political point of view,” Figueres said “100 days or 4 years are the same thing. No matter how much time has passed, the problem is the political message of rejection and denial of the climate crisis, launched by the world's largest economy "to the rest of the international community.

The Biden administration has assured its willingness to strive to reverse the course followed by Trump to date, guaranteeing its support to developing countries in the fight against climate change. In addition, the announcement of the emission reduction targets chosen by the United States is expected in April. According to Professor Nathan Hultman of the University of Maryland, Barack Obama's advisor in drafting the Paris targets, the United States could reduce its emissions by between 40% and 50% by 2030.
