Buildings Are Empty, Now They Have to Go Green
Rising rates, falling occupancy and new carbon taxes hit building owners
Rising rates, falling occupancy and new carbon taxes hit building owners
Their buildings echo with empty offices, their borrowing costs have soared, and now owners of buildings in cities across the U.S. are facing a new tax on their carbon emissions.
Cities are toughening their climate standards and are beginning to tax buildings that don’t meet the new requirements. Landlords are left with a difficult choice between paying for expensive upgrades to reduce emissions or paying the tax.
In New York City, which has one of the first and most expensive carbon taxes, landlords of large buildings (including owners of residential buildings) beginning next year will face a $268 fine for every ton of carbon dioxide emitted beyond certain limits.
“If you’re under cash flow pressure due to lack of tenancy, adding a tax on top of that isn’t a good sign,” said Bank of America CMBS Strategist Alan Todd. “It would be potentially pretty painful.”
The Wall Street Journal tallied the potential impact of the taxes on buildings that borrowed funds from Wall Street investors by issuing mortgage-backed bonds. The Journal also looked at properties owned by three of the country’s largest publicly traded landlords. The tax bill for 128 properties analysed could add up to more than $50 million during the first five-year enforcement period, which begins in 2024, according to the Journal’s analysis of Department of Building data and financial disclosures.
Fines for the same buildings could jump to $214 million if their landlords don’t meet the city’s emissions standards during the period between 2030 and 2034, the Journal’s analysis shows. The Real Estate Board of New York, an industry group, and engineering consulting firm Level Infrastructure said that more than 13,000 properties could face fines totalling about $900 million annually.
Buildings are by far New York City’s largest source of carbon emissions, which come from the fossil fuels used to heat and to provide air conditioning for them.
More than a dozen local laws regulating buildings’ carbon footprints from Chula Vista, Calif., to Boston have gone into effect since 2021 or will come online by 2030, according to carbon accounting firm nZero. Compliance also begins next year for buildings in Denver, while St. Louis properties face penalties beginning in 2025. Four other laws from Cambridge, Mass., to Reno, Nev., will go into effect in 2026.
The impact of the emissions laws initially will be small but will come on top of other, more costly problems faced by landlords. The law, based on New York’s current projections, would cost the 51-story skyscraper at 277 Park Ave. in Manhattan just $1.3 million in fines in 2024. The revenue of the building, owned by private landlord The Stahl Organization, was $129 million last year.

The building’s vacancy rate has jumped from about 2% in 2014 to 25% currently, according to commercial property data provider Trepp. JP Morgan Chase accounts for about half of the building’s space, but its lease expires in 2026. The bank is constructing a nearby tower that aims to produce net-zero carbon emissions and is scheduled to be completed in 2025. It wouldn’t comment on its leasing plans.
Stahl’s $750 million mortgage on the building is scheduled to mature next August. Stahl is now faced with potentially higher rates if it takes out a new loan, the loss of its biggest tenant and fines for carbon emissions.
Stahl declined to comment.
Shares of the three big landlords whose properties were analyzed by the Journal are trading at near historic lows. Shares of Vornado Realty Trust and SL Green, each of which has about 30 New York City office buildings, are down by roughly two-thirds since before the pandemic. Boston Properties Inc., one of the country’s largest office building owners, shares are down more than 50% from before the pandemic.
SL Green faces a potential carbon-tax liability of up to $6.6 million by 2030, according to the Journal’s analysis. The company declined to comment. More than 80 other properties financed using mortgage-backed bonds reviewed by the Journal could have a nearly $27 million carbon-tax bill by 2030.
The costly upgrades needed to comply with the law will hit some properties when they are on the block or when they are trying to attract tenants, who know they will effectively be paying for any improvements. “Tenants are looking to be in a building that is greener,” said Brendan Schmitt, partner in law firm Herrick’s Real Estate Department.

The new laws coincide with big government spending on climate. Landlords can get generous subsidies for projects that reduce emissions.
Ironically, landlords are also benefiting from emptier buildings, which burn less fossil fuel. New York City says about 11% of buildings covered under the law are projected to face penalties using the latest energy data, down from 20% using earlier data.
The city’s law was passed in 2019 and included a $268 fine for every ton of CO emitted by buildings over 25,000 square feet exceeding limits. Landlords will be required to report emissions to city officials starting in 2025 with penalties based on 2024 energy use.
Some big landlords are facing fines in multiple jurisdictions including Boston Properties, which will likely get hit on properties it owns in Boston, New York and Washington, D.C. The company’s eight New York City offices could face a $2.3 million dollar tax bill by 2030, according to city data.
Ben Myers, senior vice president of sustainability at Boston Properties, said complying with local building standards is important. “We have made energy efficiency a priority,” he said.

A bold 1950s home in Palm Springs, California, adorned with eight colorful murals by the late artist Shawn Savage, is coming to market ahead of the city’s annual Modernism Week.
The white stucco home on El Camino Way, built in 1954 and recently renovated, has an asking price of $2.295 million. Its staggered facade features three playfully abstract murals on either side of double-height hot pink doors.

The sellers are Los Angeles-based partners John Freeman and Mathieu Faure, who knew it was “the one” when they saw it after several months of searching in the winter of 2023. “It’s a happy house,” Freeman said. “We really liked the feel of the house: the uniqueness, the openness, the brightness—and the art.”
Located in the Mesa neighborhood of Palm Springs, which backs up to the San Jacinto Mountains, the 2,237-square-foot house features three bedrooms, an angled bonus room and a yard with a pool, desert mountain views and another colorful mural running alongside the pool.
“I never thought in my life I would have a house with pink doors,” said Faure, a producer at Apple TV who is originally from Paris. “It’s so colorful, it’s so different. And so Palm Springs.”
The layout of the home creates a smooth flow from the front doors through the open-plan common area—a foyer, bar, and living and dining room—into the kitchen around a fireplace wall and out to the yard. A corridor leads to a private bedroom wing, where the primary suite has floor-to-ceiling windows and the primary bath is only a tad smaller than the bedroom.
Faure has filled the home with Jonathan Adler furniture, rugs and accessories, riffing on the energetic California vibes of the house to create an aesthetic of “modern American glamour,” he said.
“It was enjoyable for me to play with different types of furniture and make this house ‘happy chic,’ as I describe it,” he said.

“He did a fantastic job,” said Freeman, who is an attorney and consultant. “It does kind of bring a smile to my face whenever I walk into the house.”
Since the furniture and decor were chosen for the particularities of the space, the couple is open to selling them with the home. Their West Hollywood house is already furnished; the collection doesn’t match the vibes of a Houston loft they bought near family; and Faure can’t imagine these pieces in New York—where he’s lived in the past—he said.
The duo bought the Palm Springs house for $1.925 million in 2024, according to property records, and will list the home Monday. They are represented by Stewart Smith, Patrick Jordan and Kevin Stanley of Bennion Deville Homes/Luxury Portfolio International.
The previous owners had purchased the home in 2021 for $975,000 and then spent more than two years and $700,000 on the renovation, according to Realtor.com. They commissioned Savage, a local Palm Springs artist and painter known for his joyful abstract work, to decorate the home.

Savage, who died in 2024, lived in the Coachella Valley from 2003, and his work can be found in various local institutions and is on exhibit at the Illumine Gallery in Palm Springs. “Some artists pass through a place. Shawn Savage became a part of it,” the gallery’s description states.
Unsurprisingly, the murals invite lots of friendly conversations, as well as guided tours and interested lookers, but never to a degree that it disturbed the peacefulness of their home or the neighborhood, the sellers said. “It felt like living in an art gallery, and you have the exterior that you would share with the world,” Faure explained.
The neighborhood also played a role in their decision to buy, because of its access to the hiking trails of the San Jacinto Mountains, the lack of through-roads and the neighborly environment.
“It’s a very friendly place,” Faure said.
