With President-elect Joe Biden slated to formally take up office in the White House in the year ahead, the upcoming U.N. Summit on Climate Change may have been given a boost by this change of administration, as the United States could be expected to find themselves back in the fold of the Paris Agreement.

The U.S. Presidential Election precedes an unprecedented period of collective international climate action, in which China, the European Union, Japan and many others have agreed to commit to long-term targets on controlling greenhouse gas emissions to meet their targets for the Paris Climate Agreement.

The United States' reintegration into the fold of the Paris Agreement, along with Biden's proposals for a "green economy" in the aftermath of the COVID-19 pandemic, could mark a historic period in which the world's largest contributors of greenhouse gases would be committed to a collective goal of reducing emissions drastically.

President-elect Biden has vowed to return the United States to the Paris Agreement, from which President Donald Trump unceremoniously withdrew in June 2017; setting a goal of reaching "net zero emissions" by 2050.

Furthermore, it can also be observed that President Biden, upon his formal return to the White House, could seek to reverse many of President Trump's unprecedented policy decisions, especially pertaining to the United States' withdrawal from the World Health Organization and the Iran Nuclear Deal (or the JCPOA).
