The mayor of New York City Bill de Blasio was mocked on Twitter Monday after he said in an interview that he wanted to “ban the classic glass and steel skyscrapers” in an attempt to bring a version of the Green New Deal to the City That Never Sleeps.

De Blasio caught heat on Twitter after proclaiming on MSNBC’s “Morning Joe” Monday morning that he wanted to “[make] the Green New Deal come alive” in the Big Apple by “ban[ning]” the construction of “glass and steel skyscrapers” if they do not meet the city’s environmental requirements.

“We’re actually making the Green New Deal come alive here in New York City. It’s three very basic ideas. One, the biggest source of emissions in New York City is buildings. We’re putting clear, strong mandates, the first of any major city on the earth to say to building owners, ‘You gotta clean up your act. You gotta retrofit. You gotta save energy.'”

“We are going to ban the classic glass and steel skyscrapers which are incredibly inefficient,” the mayor of New York City continued. “If someone wants to build one of those things they can take a whole lot of steps to make it energy efficient, but we’re not going to allow what we’ve seen in the past.”

Some people in the Twitter-sphere disagreed, however, including the national spokeswoman for the Republican party Elizabeth Harrington, who blasted the idea as “out of touch” and “radical.”

First ban cars, then planes, then cows, now… skyscrapers?

Other users torched de Blasio’s ideas, as well.

De Blasio went on in the interview to defend his use of a motorcade to go to a gym in Brooklyn 11 miles from his home in the Upper East Side as opposed to one closer to his abode most mornings.

Watch the clip below:

He excused the move by saying his “security detail” would be following him in cars wherever he went in the city and that it was “just part of [his] life.”
