In celebration of Earth Day, Mayor Bill de Blasio decided to make the five boroughs a little greener.

Mr. de Blasio today announced “the most sweeping update to New York City’s Air Pollution Control Code since 1975,” according to his office, with a “focus on pollution sources that currently have little or no emission control requirements.”

“[T]he air today in New York City is cleaner than it’s been in more than 50 years. And we’re going to work to make it better still. And for that reason, I’m proud to announce today that we’ll be updating and strengthening the city’s air pollution control code,” Mr. de Blasio said in a speech today, according to a transcript.

“This is the way we keep our air clean, and there’s more we can do to keep our air clean. And we’re devoted to doing it. We’re going to work with our friends in the City Council to make the law stronger. It is the best tool we have to ensure that every possible form of pollution of the air is addressed, and addressed stringently,” he continued. “We’re going to make sure we do that.”

The City Council will hold a hearing tomorrow on Intro 271, codifying the revisions to the Air Code. According to a memo in support of the bill, authored by Councilman Donovan Richards, the legislation would “introduce new requirements to limit emissions from certain unregulated sectors, while promoting the adoption of cost-effective air pollution controls.”

The bill specifically targets commercial char broilers, outdoor boilers, mobile food trucks and fire places, which will be required “to use only natural gas or renewable fuels in order to reduce the amount of pollutants.”

Though the bill only has a handful of sponsors so far, Council Speaker Melissa Mark-Viverito is fully on board.

“For years, New York City has been at the forefront of sustainable and responsible environmental practices,” she said in a statement released by the mayor’s office. “These reforms continue that trend by protecting our air, our water, and our city’s residents from harmful emissions.”
