“La guerra al carbone è finita”. Lo ha detto, riecheggiando le parole del presidente Usa, Donald Trump, il capo dell'agenzia federale dell'ambiente (Epa), Scott Pruitt. Che nelle prossime ore firmerà il piano per rottamare il 'Clean Power Plan'. Il provvedimento era stato introdotto dall'amministrazione Obama nell’ambito degli sforzi per ridurre il livello di emissioni inquinanti delle centrali elettriche del 32 per cento entro il 2030. Per il capo dell'Agenzia per la protezione dell'ambiente, il regolamento introdotto da Obama nel 2015 era "illegale" e "definiva vincitori e perdenti" nella competizione per produrre energia elettrica negli Usa. "Il potere regolatorio non dovrebbe mai essere usato per definire vincitori e perdenti", ha attaccato Pruitt. Durante la campagna elettorale per le presidenziali, Trump aveva ripetutamente criticato gli allarmi sui rischi connessi al cambiamento climatico globale, definendoli "bufale cinesi" e annunciato il ritiro degli Usa dagli accordi di Parigi sul clima. Una volta eletto ha poi dato mandato all’Epa di rivedere i provvedimenti adottati dall’amministrazione Obama.

US Environmental Protection Agency (EPA) Administrator Scott Pruitt has announced his plan to withdraw from the Clean Power Plan, a regulation enacted by former President Barack Obama to tackle climate change, on Tuesday. Obama unveiled the Clean Power Plan, the first national carbon pollution standards for power plants in the country's history, in August 2015. The initiative came within the 2015 Paris climate deal, a global accord which aims to limit global average temperatures to less than 2 degrees Celsius above the pre-industrial level. In November 2015, Obama banned the construction of 1,179-mile Keystone XL oil pipeline that was expected to run from Alberta, Canada to Steele City, Nebraska. "Tomorrow in Washington DC I'll be signing a proposed rule to withdraw the so-called Clean Power Plan of the past administration and thus begin the effort to withdraw that rule … Here's the president's message – the war on coal is over," Pruitt said at a joint event with Senate majority leader Mitch McConnell in Hazard, Kentucky. The EPA chief stressed that Obama's Clean Power Plan was not "about regulating to make things better," but rather unfair in its nature. "That rule really was about picking winners and losers. Regulatory power should not be used by any regulatory body to pick winners and losers. The past administration was unapologetic, they were using every bit of power, authority to use the EPA to pick winners and losers on how we pick electricity in this country. And that is wrong," Pruitt stressed. During his presidential election campaign, then-Republican candidate Donald Trump repeatedly criticized warnings about global climate change, saying it was a "Chinese hoax," and speculated about ending US participation in the Paris climate deal on carbon emissions. In March, Trump signed an executive order, instructing the US EPA to review and potentially withdraw from the Clean Power Plan. Then, in early June, Trump announced that the United States would be withdrawing from the Paris climate agreement. Officially, Washington notified the UN of its withdrawal on August 4.
