New York Mayor Bill de Blasio said on MSNBC Monday morning his city will ban “inefficient” steel and glass skyscrapers as part of their Green New Deal. While Rep. Alexandria Ocasio-Cortez’s Green New Deal sputtered in Washington D.C., her home city of New York has embraced key pillars of the plan. When asked about it on Morning Joe, de Blasio outlined the proposal. “We are making the Green New Deal come alive here in New York City,” he said. “It’s three very basic ideas. One, the biggest source of emissions in New York City is buildings.”
