About Koyasan Saizenin.

Koyasan Saizenin is a 3-star hotel in Koya, Japan, 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 Family rooms, Free car parking, Non smoking rooms, Parking, Garden, Internet access.

That makes Koyasan Saizenin one of the genuinely eco-friendly, sustainable, and climate-positive stays available in Koya. 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 Koya can book Koyasan Saizenin 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 Koya →

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 Koyasan Saizenin.

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

Sustainability

01 · Sustainability#

Is Koyasan Saizenin a carbon-neutral hotel?

Yes. Every booking of Koyasan Saizenin through IMPT funds 1 ton of UN-verified CO₂ removal — physically pulled from the atmosphere, retired on-chain, no double-counting. That's about 28× the per-night footprint, fully removed at no extra cost to the guest.

02 · Sustainability#

What makes Koyasan Saizenin an eco-friendly hotel?

Koyasan Saizenin is bookable through IMPT's green hotel programme: every stay funds 1 ton of UN-verified carbon removal, the booking is rate-matched or cheaper than direct, and the property's residual emissions are offset against measured atmospheric removal — not avoidance offsets.

03 · Sustainability#

Is Koyasan Saizenin a sustainable hotel?

Sustainable hospitality has four pillars — energy, water, waste, community. Koyasan Saizenin is part of IMPT's green programme, and the residual carbon footprint of every stay is fully removed via UN-verified projects. Property-specific certifications (LEED, Green Key, EarthCheck) are listed on the page when available.

04 · Sustainability#

Who verifies the carbon removal at Koyasan Saizenin?

Every credit IMPT retires is independently audited under United Nations carbon frameworks — the most rigorous standard available. Each tonne removed by a booking at Koyasan Saizenin is publicly trackable on-chain at app.impt.io/projects. No double-counting, no avoidance credits.

05 · Sustainability#

Is the carbon at Koyasan Saizenin really removed, or just offset?

Removed. Most travel programmes buy avoidance offsets — certificates representing emissions someone promised not to produce. IMPT funds physical removal credits under the UN framework. The CO₂ is actually pulled from the atmosphere, the credit is retired on-chain, and it can't be resold.

06 · Sustainability#

Does it cost more to book Koyasan Saizenin as a green hotel?

No. You pay the same rate as direct — often less. The 1 ton of CO₂ removal is funded from IMPT's commission, not added to your bill. Free cancellation is available on most rooms.

07 · Sustainability#

How much CO₂ does my stay at Koyasan Saizenin actually remove?

Each booking funds 1,000 kg (1 ton) of UN-verified CO₂ removal — the equivalent of about 45 trees grown for a year, 79 days of driving avoided, or one return flight London→New York fully neutralised.
