After years of inertia, a number of countries have begun taking new steps to address the climate change challenge. The EU has launched its Green New Deal (GND) on December 2019, just before the burst of COVID-19 outbreak. Joe Biden, new president of the US, has made clear, in his speech after the election, that environment will be one of the most prominent issues on which he will lean during his presidency. Similarly, China, despite the lack of a comprehensive GND, has assured that it will fulfill by 2060 the climate neutrality obligation imposed by the Paris Agreement.
