With the new government in the United States, there has also been a significant change in the country’s environmental strategy. This will have an impact on the global climate agenda. The United States is the world’s second-largest producer of greenhouse gases, therefore, the announcement that it is rejoining the Paris Agreement, which sets them on the road to climate neutrality, is excellent news. In the meantime, China, the main emitter, announced in November last year that it aims to be carbon neutral by 2060. These two countries, together with Europe, are the world’s main CO2 emitters, therefore, their zero-emissions objectives are pivotal in the fight against climate change. According to the spokesperson of the head of the UN, the Paris Agreement came into force for the United States today, 19 February 2021, so today is a day for celebration!
