Bill de Blasio says Green New Deal will ban ‘inefficient’ steel and glass skyscrapers
If the Big Apple is to become the Green Apple, it will have to ban the steel and glass towers that form its signature skyline, according to Mayor Bill de Blasio.
De Blasio, speaking on MSNBC’s “Morning Joe” said that city’s most iconic structures – the tall skyscrapers seen from miles away – are the “biggest source of emissions” in New York City. The drastic change, and a switch to only renewable energy within five years, are necessary for Gotham to embrace the Green New Deal, de Blasio said.
“We are putting clear, strong mandates” to lower emissions, he said, warning property owners will face massive fines unless buildings are retrofitted.

New York City Mayor Bill de Blasio says the city’s most iconic structures – its towering skyscrapers– are its ‘biggest source of emissions.’

“We are putting clear, strong mandates” to lower emissions, he said, warning property owners will face massive fines unless buildings are retrofitted.
“The first of any major city on the Earth to say to building owners, ‘you've got to clean up your act, you've got to retrofit, you've got to save energy,’” he said. “If you don’t do it by 2030 there will be serious fines, as high as $1 million or more for the biggest buildings.”
He continued: “We’re going to ban the classic glass and steel skyscrapers, which are incredibly inefficient. 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 used to see in the past.
