Sustainable & green accommodation: IMPT lists eco-friendly hotels, green-certified stays, sustainable guesthouses, and responsible travel options — from carbon-neutral hotels and eco lodges to environmentally friendly B&Bs and net-zero accommodation. Every booking removes 1 tonne of verified CO₂ at the lowest price guarantee — same as Booking.com or better.
🌍 Your Carbon Impact at This Hotel
An average hotel night produces roughly 35 kg of CO₂ — from air conditioning, laundry, lighting, and food. When you book The King William Hotel through IMPT, we retire 1,000 kg of UN-verified carbon removal credits. That's not carbon-neutral. That's carbon-negative.
How it works: IMPT funds the carbon removal from its booking commission — you pay €0 extra. Credits come from UN-verified regenerative agriculture projects, tokenised on Ethereum, with a public retire code anyone can verify. No double-counting. No greenwashing.
