New York City Seeks To Reduce Carbon Emissions From Buildings By 40%

Buildings account for 67% of all carbon emissions in New York City. The city council has just passed a resolution mandating a reduction in emissions from large buildings of 40% by 2030.

Climate advocates know that meeting the goals of the Paris climate accords means more than generating more renewable energy. It also requires reducing emissions from existing sources. At present, 67% of all greenhouse gas emissions  in New York City come from buildings, not from transportation as you might expect.

On April 18, the city council of New York gave its approval to an ambitious plan that calls for every building in the city more than 25,000 square feet in size to reduce its carbon emissions by 40% no later than 2030. The new policy will apply to more than 50,000 buildings in the city, including Trump Tower.

“It will be the largest emissions reduction policy ever, in any city,” says city councilor Costa Constantinides, who led the campaign to enact the new policy. According to The Guardian, the law puts a cap on how many tons of carbon a building may produce per square foot, with different limits for residential, commercial, and industrial buildings.

New York carbon emissionsTo reach the goal, many buildings will need to replace heating or air conditioning systems with more efficient equipment. Energy efficient windows and better insulation will also be part of the plan. Finally, converting as many systems as possible to run on renewable electricity rather than fossil fuels will be a necessary part of meeting the new requirements.

Not everyone is happy with the new policy. “The approach taken today will have a negative impact on our ability to attract and retain a broad range of industries, including technology, media, finance and life sciences, that provide opportunity and continued economic growth that is so important for our city,” says John Banks, president of the Real Estate Board of New York.

Rent stabilized apartments will be exempt from the caps, though they will be required to do some upgrades to improve energy efficiency. Churches, synagogues, and mosques are also exempt. What is surprising is the city’s public housing units are exempt as well, which seems like a “Do as we say, not as we do” position. John Banks says the exceptions unfairly leave “mostly market-rate housing and commercial buildings to shoulder the entire burden of what is undeniably a shared societal problem.” He has a point.

Others complain the new policy does not go far enough. They point out that huge energy savings are possible with new refrigerants and the cooling equipment designed to operate using the latest technology. Once again, they are not wrong, but the burden of the new regulations should incentivize building owners to retrofit existing buildings with the most energy efficient air conditioning devices available.

The owners of buildings that do not meet the carbon reductions mandated could be fined up to $268 a year for every excess ton of carbon they emit. That could add up to millions of dollars in fines for the worst offenders. A carbon credit trading system may follow, but it has not progressed past the planning stage as of yet. The city’s long range goal is to reduce the carbon emissions from buildings 80% by 2050.

Under the plan, new buildings will be required to have “green” roofs or rooftop solar systems, requirements that Paris initiated four years ago. San Francisco is the only US city to have enacted similar requirements so far.

Mayor Bill DeBlasio is expected to approve the city council’s bold new initiative. “It’s going to revolutionize our ability to reduce emissions through our buildings, which are really our number one problem here in New York City,” he says. “We were going to need to do something very aggressive, particularly because the federal government is not doing their role.”
