New York City, US has approved a new environmental regulation mandating pizzerias and matzah bakeries to significantly reduce emissions from their traditional wood and coal-fired ovens, the New York Post has reported.

The new rule requires a 75% reduction in pollutants from pizzerias operating wood and coal-fired stoves.

The Department of Environmental Protection (DEP), under Mayor Eric Adams, has announced that the rule will take effect on 27 April 2024. Some businesses have already invested in emission-control air filter systems in anticipation of the mandate.

Businesses operating with wood and anthracite stoves have the option to apply for a variance if they can demonstrate their inability to comply with the new requirements.

DEP spokesperson Edward Timbers was quoted by the New York Post as saying: “The scientific evidence is clear that reducing emissions of fine particulate matter will improve the health of New Yorkers and reduce hospital visits and costs, without changing the amazing taste of NYC pizza.”

Around 130 businesses in the city are expected to be impacted by the new regulation.

The move has prompted a public debate. Critics have questioned the focus on pizza ovens rather than on other pollution sources such as diesel trucks, and highlighted the challenges the new rule poses to small businesses.

The regulation applies to ovens installed before May 2016 and aligns with a 2015 law enacted during Bill de Blasio's tenure as mayor. The law requires coal and wood-fired pizza restaurants to limit their emissions.

Establishments that cannot meet the 75% reduction target must provide assessments justifying their situation and strive for at least a 25% decrease in emissions.
