NPR does a point-by-point fact check of Trump's plan for his first 100 days, when he starts to make 'America great again'.
 

...So where to start for President-elect Trump, who at one campaign stop said 70 percent of regulations "can go”? One likely place: the environment. An EPA power plant rule aims to cut carbon emissions by nearly a third by 2030. Trump couldn’t simply veto the regulation, however, although Congress could vote to overturn it. But a Trump administration could certainly weaken enforcement of the standard.

The banking sector is another place for Trump to focus. During the campaign he said he wanted to "get rid of" the Dodd-Frank law that reshaped the banking industry after the 2008 recession. If repealing the entire law seems a heavy lift, one possibility would be to try to eliminate the so-called Volcker rule, which prohibits banks from making risky investments.

Republicans make no secret of their dislike of the recent Federal Communications Commission ruling that protects net neutrality. The Trump administration could also attempt to repeal a regulation that makes more workers eligible for overtime.
