About Hotel Los Delfines.

Hotel Los Delfines is a 4-star hotel in Cartagena, Spain, bookable through IMPT's carbon-neutral hotel programme. Every booking removes 1 ton of UN-verified CO₂ from the atmosphere — physically extracted under United Nations carbon frameworks, retired on-chain, and paid from IMPT's commission at no extra cost to the guest. On-site facilities include Free Wifi, Family rooms, Swimming pool, Bar/Lounge, Outdoor pool, Non smoking rooms.

That makes Hotel Los Delfines one of the genuinely eco-friendly, sustainable, and climate-positive stays available in Cartagena. The carbon-removal model used here differs from conventional offsets in three ways: removal credits are physically pulled from the atmosphere rather than representing avoided emissions; every retirement is recorded on a public blockchain so the credit can't be resold or double-counted; and verification is handled under UN frameworks — the most rigorous standard available.

Travellers searching for an eco hotel, green hotel, sustainable accommodation, or net-zero stay in Cartagena can book Hotel Los Delfines at the same rate as direct (often less), with free cancellation on most rooms and a discounted price applied automatically at checkout. The IMPT booking is rate-matched against Booking.com and Hotels.com — the green angle never costs you extra. Browse other carbon-neutral hotels in Cartagena →

Why this is genuinely different.

Removal

Real removal. Not offsets.

IMPT funds UN-verified carbon removal — physically pulled from the atmosphere, not a credit that might be resold.

Price

Same rate as direct.

The carbon removal comes from IMPT's commission. You pay the same as Booking.com or Hotels.com — often less.

Trust

Publicly tracked.

Every tonne is retired on-chain and listed publicly. UN-framework aligned. No double-counting.

How it works.

1
Book

You book Hotel Los Delfines.

Same rate as any other platform — often cheaper. Pick dates, hit Book Green, done in 60 seconds.

2
Remove

IMPT removes 1 ton of CO₂.

Funded from IMPT’s commission. Real projects. Real carbon pulled from the atmosphere — UN-verified.

3
Verify

You can track the impact.

Every tonne is retired on-chain — project, location, verification body, immutable. No double-counting.

UN-verified. The highest standard.

UN
VERIFIED

Why UN verification matters.

Most hotel "carbon-neutral" programmes use cheap avoidance offsets — credits that have been over-counted, double-sold, or untraceable. IMPT only retires UN-verified removal credits, the most rigorous independent standard available, and records each retirement on-chain so the credit can never be resold.

UN-verified Removal not avoidance On-chain retired No double-counting
