New York City may soon force pizzerias to pay thousands of dollars in renovations to keep their coal and wood-fire ovens over environmental concerns with air quality, according to a report.

The New York City Department of Environmental Protection (DEP) has drafted new rules that would require pizzerias with coal and wooden-fire ovens installed prior to 2016 to cut carbon emissions by 75%, according to the New York Post. Restaurant owners would be forced to install a filter to the specified ovens then hire an engineer to regularly inspect the carbon emissions.
