Cruises – GHG Calculator

Step 1 — Cruise details

Passengers: Total days: Days in port:

We assume port days emit 30% less CO₂e than sea days.

Step 2 — Select ship category

Category	Typical passengers	Example	kg CO₂e / passenger-day
Small expedition	< 200	Arctic / Galápagos	180
Medium cruise	200 – 1,000	Regional / Boutique	250
Large cruise	1,001 – 5,000	Caribbean / Alaska	320
Mega cruise	> 5,000	Ocean liner	380

Step 3 — Calculate cruise emissions

Step 4: Contribution Level ($/tonne)

$800 / tonne (full cost)
$400 / tonne (half cost)
$80 / tonne (entry level)
Custom Amount:

Please note that only donations of $20 or greater will be issued tax receipts
