If you've ever found yourself toggling between booking a nice hotel and feeling guilty about your environmental impact—you're not alone. But here's some relief: more hotel groups in Europe are getting serious about sustainability, and not just for the press release. We're talking real, measurable eco-efforts happening behind the scenes, without sacrificing comfort, aesthetics, or good service.

These are not rustic hostels with composting toilets and scratchy sheets. They’re stylish, well-run hotel chains that are leading the way for modern travelers who want both thoughtful design and eco-credentials they can trust.

So if you're after a city break that won't weigh heavily on your conscience or you're booking a longer Europe trip and want your hotel chain to reflect your values, here are six eco-conscious hotel brands we trust—and that you’ll actually want to stay in.

1. Radisson Blu – Understated Sustainability in Big Cities

We love a hotel that doesn't make a whole show out of being eco-friendly but still does the work. Radisson Blu is one of those. You’ll find them in cities like Copenhagen, Berlin, and Amsterdam, and they quietly deliver on sustainability without losing their signature sleek aesthetic.

They’re part of the Radisson Hotel Group’s commitment to becoming net zero by 2050, and many of their properties use renewable energy, reduce food waste, and operate with energy-efficient tech. Their green rooftops and partnerships with local sustainability initiatives show that they’re thinking beyond their own doors.

Tripper Tip: Copenhagen's Radisson Blu Scandinavia is a great one to check into if you’re after a balance of eco-conscious comfort and access to the city's best walking routes and coffee spots.

2. NH Hotels – Sustainability Without Compromise

If you're into city breaks with style (and want to keep your wallet and conscience equally happy), NH Hotels delivers. Found all across Europe—from Seville to Stockholm—they're quietly doing sustainability in a way that feels accessible, not preachy.

Expect smart energy use, LED lighting, and policies that reduce water waste. NH Hotels also works on sustainable sourcing, including eco-friendly toiletries and Fairtrade coffee. But more importantly, the design and vibe never feel like a compromise.

Ideal for: Solo trips, workcations, and couples who want a central, clean, good-looking base that aligns with their values without being too flashy about it.

3. The Hoxton Hotels – A Trendy Eco-Conscious Choice

Yes, The Hoxton is cool. But beneath the hip interiors and effortlessly trendy vibe, they’re also making some seriously good decisions when it comes to sustainability. Think repurposed materials, thoughtful supply chains, and menus designed to reduce food waste.

Their locations in London, Amsterdam, and Paris make them perfect for design-loving travelers who want their stay to reflect their values without losing the aesthetics. You get the vintage furniture, the curated playlists, the comfy robes—and you also get a hotel that’s working toward a lower carbon footprint.

Pro move: Grab a local, seasonal breakfast at the lobby restaurant before heading out on foot—most Hoxtons are in walkable neighborhoods.

4. CitizenM Hotels – Where Comfort and Sustainability Collide

CitizenM is what happens when a hotel actually listens to what modern travelers want. Affordable luxury, smart tech, and now—a real commitment to eco-conscious practices.

They’re compact by design (fewer materials used = lower impact), and use energy-efficient systems throughout. Most rooms are identical, which minimizes waste during building and operations. And behind the scenes? They're working on being fully carbon neutral, one city at a time.

Why we like it: These hotels are consistent. You know what you’re getting: a solid bed, a great shower, excellent Wi-Fi, and minimal environmental guilt. They're also great for solo trips, especially if you’re city-hopping.

5. Accor Hotels – Sustainability as a Core Value

Accor is a huge hotel group, but their Planet 21 initiative proves they’re not just about scale—they're about responsibility. From eliminating single-use plastics to working with eco-labeled suppliers and reducing water use, they’re making sustainability core to their operations.

Their European properties span everything from boutique hotels to budget-friendly spots, meaning there’s something for every kind of traveler. What stands out is how embedded the sustainability work is—you see it in the design, the operations, and the training their staff receive.

Good to know: Many Accor hotels offer refillable water stations, Fairtrade coffee, and bike rental options—small things that add up during your stay.

6. InterContinental Hotels Group (IHG) – Where Green Luxury Meets Travel

IHG’s eco-initiatives are serious. They’re working toward net zero, prioritizing energy efficiency and reducing waste across all their brands—from InterContinental and Crowne Plaza to Holiday Inn Express.

At many locations, you’ll notice refillable amenities, smart energy systems, and even zero-waste dining concepts. InterContinental Paris, for example, mixes five-star service with thoughtful sustainability. It’s proof that luxury doesn’t have to be excessive.

For the conscious traveler who still loves a plush robe and room service: This is the chain that lets you have both.
