London’s Sustainable Event Venues
Discover a new generation of London venues that blend innovation, sustainability and style, proving that hosting responsibly doesn’t mean compromising on experience.
From nature-led luxury hotels to next-generation conference spaces, these venues are leading the way in creating unforgettable events with a lighter footprint.
There’s so much more out there, but here are a few of our current favourites that we’ve been talking about with clients recently.
The Conscious Luxury: 1 Hotel Mayfair
Where biophilic design meets mindful meetings
Nestled in the heart of Mayfair, 1 Hotel Mayfair has redefined what sustainable luxury looks like. Built by retaining over 80% of the original structure, the hotel minimises embodied carbon while surrounding guests in natural light, living walls, and reclaimed timber finishes.
Why it works for business: With 181 rooms and a selection of beautiful meeting spaces - including private dining and executive boardrooms - the hotel’s Certified Sustainable Gatherings programme makes sustainability seamless for planners. It’s ideal for leadership retreats, incentive stays, or premium brand events that want sophistication with substance.
The Powwow Perspective: Step inside and it’s calm, tactile, and quietly elegant. The moss walls and textured stone create a sensory experience that feels fresh, natural, and deeply luxurious - the perfect environment for clear thinking and creative conversation.
The Super Boutique: The Londoner, Leicester Square
Scale, sophistication, and sustainability at the centre of it all
Described as the world’s first super boutique hotel, The Londoner combines the intimacy of a design-led hotel with the capacity of a major conference venue. Beneath its sleek glass façade lies an extraordinary six-level subterranean world dedicated entirely to events.
Why it works for business: The Ballroom hosts up to 850 guests for receptions and 600 for seated events, supported by a series of stylish breakout spaces. Behind the glamour, The Londoner’s BREEAM Excellent rating reflects serious sustainability credentials - from 100% renewable energy to energy-sharing systems that reduce carbon emissions across Leicester Square.
The Powwow Perspective: Modern, bold, and beautifully British. The interiors are a masterclass in understated elegance - all soft lighting, plush textures, and clever zoning that keeps even large-scale events feeling intimate. A standout choice for high-profile London showcases.
The Modern Classic: Convene, 22 Bishopsgate
Where next-gen tech meets sustainable design
Occupying a prime position in London’s tallest building, Convene has fast become one of the City’s most innovative event spaces. With flexible layouts, cutting-edge AV, and all-day dining included as standard, it’s designed to take the stress out of large-scale meetings and conferences.
Why it works for business: Multiple spaces accommodate groups from 30 up to 400 delegates. Convene’s commitment to sustainability includes carbon-neutral operations, locally sourced catering, and a design philosophy centred on natural materials and energy efficiency. It’s perfect for high-impact corporate meetings, summits or client events that demand a premium experience without excess.
The Powwow Perspective: Sleek, efficient, and quietly stylish — Convene is the kind of venue that makes you look good without trying too hard. It’s proof that sustainability can be practical, scalable, and effortlessly modern.
The Reimagined Icon: Olympia London
Heritage meets innovation in a new era for exhibitions and experiences
An icon of London’s event scene for over a century, Olympia London is undergoing a £1.3 billion transformation - one that places sustainability and creativity at its core. The venue has already achieved Zero Waste to Landfill status for over a decade and is part of the Net Zero Carbon Events Pledge, aiming for net zero by 2050.
Why it works for business: With capacity for thousands, Olympia is ideal for major conferences, exhibitions, and product launches. The upcoming expansion will add new hotels, restaurants, and performance spaces — turning it into a complete cultural and business destination.
The Powwow Perspective: Few venues manage to balance heritage with forward thinking quite like Olympia. It’s vast but human, industrial yet warm — and its ongoing transformation is set to make it one of Europe’s most sustainable large-scale event campuses.
In Summary
From 1 Hotel’s biophilic calm to The Londoner’s glamorous efficiency, from Convene’s tech-forward precision to Olympia’s grand ambition, these venues show that sustainability and sophistication can go hand in hand.
Each has a distinct personality, but all share the same promise that aligns with us here at Powwow: they make business events not only memorable, but meaningful.
