Trump exiting Paris accord will harm US economy – LSE research

Economists say falling cost of clean energy and growing climate risks strengthen case for cutting CO2 emissions

Withdrawing from the Paris agreement does not make economic sense for the US, a group of economists has argued, as the cost of clean energy has fallen since the agreement was signed in 2015, while the risks of climate catastrophe have increased.

Economists from the Grantham Institute for Climate Change at the London School of Economics examined the economic case for the US withdrawal, which President Donald Trump signalled in June 2017, and which will take effect on 4 November, the day after this year's presidential election.
