Forget carbon neutral. Soon that term will be passé. Net-zero goes much further than simply paying someone else to offset emissions while still relying on fossil fuels for heating and cooling.
Here’s a look at six hotels and resorts that are leading the way.
room2 Chiswick, London
London’s room2 Chiswick has a biodiverse green roof that absorbs CO2.
Recognizing the climate crisis, room2 owner Robert Godwi spent two years planning a “whole life” net-zero hotel.
That means shredding the carbon footprint from construction through to running the hotel, which opened in late 2021.
“The result is a hotel that is 89% more energy-efficient and shows what can be done.”
Clearly, net-zero energy doesn’t mean net-zero luxury.
At first glance, it might seem like just another design hotel, with its terracotta floors, pendant lights, and lush red velvet bar stools.
Giveaways include the power sensors in rooms and a host of invisible elements like a ground source heat pump, water-saving fixtures, and a ‘blue roof’ that converts rainwater into energy. A biodiverse green roof uses 200 tons of soil and wildflowers aimed to absorb CO2.
Wren Urban Nest, Dublin
Tucked down a quiet street between Temple Bar and Trinity College, this newcomer declares itself “Dublin’s most sustainable place to stay.”
The capsule hotel with 137 pod rooms or “nests” was designed “using advanced carbon reduction technologies,” says architect Michael Mullen.
“The ventilation system captures 81% of rejected heat using a thermal wheel and heats incoming fresh air for free,” he adds.
That energy is also used for hot water, while the hotel kitchen snubs gas. Water conservation and low-loss fittings make water demand “approximately 60% lower than a typical hotel”.
Peep in and you will quickly realize that ditching carbon offsets doesn’t put a dint in design. Scandinavian minimalism — wood, wicker lights and natural hues — meet Irish textiles and furniture, and abundant greenery.
“Cosy” and “Snug” bedrooms, just 9.5-12 square meters (102-129 square feet), pack in “compact luxury” with amazing energy efficiency. But that doesn’t rule out Chromecast and lightning-fast WiFi. Or handmade soaps, locally crafted mugs and rugs, and roasted coffee.
Comfort Hotel Solna, Sweden
In June 2021, Scandinavia welcomed its first certified “zero-energy” hotel. The 336-room Comfort Hotel Solna lies a few miles north of central Stockholm.
The angular building sports 2,500 square meters of colorful solar cells, making it “the world’s most photovoltaic-dense.”
“We generate enough solar power to send a Tesla around the world 50 times!” the hotel boasts on its website. And more than its annual energy needs.
“Nothing is left to chance,” says owner Petter Stordalen. “The elevators charge when they go down to power the ascent. The building is cooled and heated by heat pumps that fetch energy from borehole bearings (underground thermal energy storage).
From the maritime-themed rooms to industrial-chic Barception (the bar-reception), this “energy-smart” hotel shows off Nordic design while being relatively easy on the wallet. The light-filled space is fitted with wood, raw steel, earthy colors, and Bakelite bowl suspended lighting.
Boutiquehotel Stadthalle, Austria
A sustainable oasis in the heart of Vienna.

Long before hotels began touting their net-zero virtues, it turns out there was a true zero-emissions pioneer in Vienna.
In a restored turn-of-the-century house surrounded by solar panels and garden beds, the 79-room Boutiquehotel Stadthalle has been running on solar power and other renewables since 2009.
“A zero-energy balance may not sound sexy for a hotel,” says owner Michaela Reitterer. “But our guests think it is. About 70% stay because of our ‘green at heart’ vision.
“We generate as much energy in a year with a groundwater heat pump, solar panels and photovoltaic technology as we consume. Excess goes into the grid and sometimes in peak seasons, we source surplus renewable energy from the city, such as Biomass.”
The quirky rooms flaunt recycled wine bottle chandeliers, upcycled wood furniture, sheep bedheads and Klimt prints. Forget energy-guzzling minibars. Try a few chords on a piano instead.
Breakfast is in the interior courtyard “oasis” among herb pots, flowers, and ivied walls. Up above, the lavender roof bursts with butterflies and bees.
Hailed as Vienna’s “green queen,” Reitterer says she took a really long-term view betting on renewable energies in her quest to “change the world,” starting out in a “sustainability Stone Age.”
Hotel Marcel, New Haven, Connecticut
The new Hotel Marcel New Haven, part of the Tapestry Collection by Hilton, is a 165-room hotel inside the city’s iconic Pirelli building that’s “powered solely by the sun” and is fusing a legendary past with a climate-first future.
It operates independent of fossil fuels, resulting in zero carbon emissions.
“Fossil fuels are really a 20th-century technology, and they are more expensive to use now,” says Bruce Becker, the architect-developer behind Hotel Marcel.
“A net-zero hotel is really self-sufficient and makes all the energy it uses.”
“Over 1,000 solar panels generate all the electricity to meet the needs of the building,” says Becker.
“Solar panels covering the rooftop and parking canopies provide 100% of electricity for lighting, heating, cooling, and electric car charging stations.”
Behind its gridded concrete facade, the Hilton Tapestry Collection hotel boasts walnut furniture, white terracotta tiles and Bauhaus geometric print rugs — all custom-designed.
The rooms have touchpad controls for controlling temperature, lighting, and automatic shades. Triple-glazed windows and dramatic views of Long Island Sound meet curated art, retro lights and original wood-paneled walls.
Four Elements Hotel, Amsterdam
The Four Elements Hotel’s Herbs Garden Restaurant.
This “eco-luxe” hotel on the edge of Amsterdam’s Ijmeer Lake snuck in almost unnoticed in 2019.
Never has green looked so sexy as from the top floor Wind Sky Bar, with its recycled wood banquettes, exposed pipes, orange poufs and peacock blue fabrics. Meanwhile, the Herbs Garden restaurant fancies traditional fermentation, preserving, pickling and smoking.
The decor in the 195 rooms is also Dutch gezellig cozy. Behind the moss encased numbers lie salvaged timber floors and repurposed brass bedheads and architectural lighting.
