Indeed, research shows that the cost of climate activity far outweighs the cost of reducing carbon pollution. A recent study suggests that if the United States does not meet its climate targets in Paris, it could cost the economy up to $6 trillion in the coming decades. A lack of compliance with the NPNs currently foreseen in the agreement could reduce global GDP by more than 25% by the end of the century. Meanwhile, another study estimates that achieving – or even exceeding – the Paris targets by investing in infrastructure in clean energy and energy efficiency could have great benefits globally – about $19 trillion. Taking part in an election campaign promise, Trump – a climate denier who has claimed that climate change is a “hoax” perpetrated by China, announced in June 2017 his intention to withdraw the United States from the Paris Agreement. But despite the rose garden president`s statement that “we`re going out,” it`s not that simple. The withdrawal procedure requires that the agreement be in effect for three years before a country can formally announce its intention to withdraw. She`ll have to wait a year before she leaves the pact. This means that the United States could formally withdraw on November 4, 2020, the day after the presidential elections.
Even a formal withdrawal would not necessarily be permanent, experts say. a future president could join us in a month. At the 2011 UN Climate Change Conference, the Durban Platform (and the ad hoc working group on the Durban Platform for Enhanced Action) were created to negotiate a legal instrument to mitigate climate change from 2020. The resulting agreement is expected to be adopted in 2015.  The Kyoto Protocol, an environmental treaty adopted at COP3 in Japan in 1997, is the first time that nations have agreed on country-by-country emission reduction targets. The protocol, which only came into force in 2005, set binding emission reduction targets only for industrialized countries, based on the fact that they are responsible for most of the world`s high greenhouse gas emissions. The United States first signed the agreement, but never ratified it; President George W. Bush argued that the agreement would hurt the U.S. economy because developing countries such as China and India would not be included. In the absence of the participation of these three countries, the effectiveness of the treaty was limited, as its objectives covered only a small fraction of total global emissions. In the agreements adopted in Copenhagen in 2009 and Cancun in 2010, governments set a target of keeping global temperature increases below 2 degrees Celsius above pre-industrial levels. The Paris Agreement reaffirms the 2-degree target and insists that the increase be limited to 1.5 degrees Celsius.
