Carbon Footprint & Offset Report: Milford Sound Fly Back Experience: Cruise & Scenic Flight
Quick Snapshot
Estimated CO₂e footprint per participant: 420 kg CO₂e
(higher-end conservative estimate – covers all on-tour impacts plus average local travel to/from Queenstown pickup points)
Our 200% offset commitment per booking: 840 kg CO₂e
Funded through genuine landscape restoration in climate-vulnerable developing regions (reforestation, mangroves, soil regeneration, etc.). This creates real net-positive impact beyond neutrality.
Tour summary
- 10-hour full-day tour
- Small group – max 16 guests
- Starts and ends with hotel pickup/drop-off from Queenstown accommodations
- Modern air-conditioned minibus + boutique Milford Sound cruise + scenic flight return
- No accommodation included
- Meals: Lunch with mountain views, snacks & bottled water
- Highlights: Scenic drive through Fiordland with photo stops (Mirror Lakes, Eglinton Valley, Homer Tunnel), intimate Mitre Peak small boat cruise, scenic flight back over the Southern Alps, wildlife spotting (seals, kea), expert local guide commentary
Overview
This report estimates the carbon footprint for one individual participant on this tour using higher-end data from trusted sources. We intentionally choose upper-range figures to fully cover every impact – including hard-to-measure parts like supply chains and indirect effects.
We then double it (200%) and fund genuine landscape restoration projects in developing and climate-affected regions worldwide. This goes beyond standard offsetting to deliver real, lasting benefits for ecosystems and communities.
All figures in kg CO₂e (carbon dioxide equivalent – the standard measure that includes all greenhouse gases).
Tour Details
- Duration: 10 hours
- Key locations: Queenstown hotel pickups, Milford Road (Mirror Lakes, Eglinton Valley, Homer Tunnel), Milford Sound (small boat cruise), scenic flight return over Southern Alps
- Travel style: Premium small-group experience combining scenic drive, intimate cruise and scenic flight
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to Queenstown hotel pickup points is factored into the higher-end footprint for completeness.
Calculation Approach
- Sources: UK DEFRA 2025 conversion factors, Australian National Greenhouse Accounts 2024, UNWTO tourism data, IPCC guidelines, and peer-reviewed studies.
- Higher-end scale: Upper-range emission factors everywhere, plus radiative forcing for the scenic flight, well-to-tank fuel effects, +20% uncertainty buffer, and conservative assumptions for minibus + marine cruise operations.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. souvenirs or additional purchases).
Detailed Emissions Breakdown (per participant)
Transportation – 320 kg CO₂e
- Average local travel to/from Queenstown pickup points (higher-end mix of car, taxi or short transfers): 30 kg
- On-tour minibus (~480 km round trip, shared small group) + boutique cruise + scenic flight return: 290 kg – higher-end diesel + marine + aviation factor with low-occupancy buffer
Accommodation – 0 kg CO₂e
- Day tour only – no overnight stay
Meals & Food – 60 kg CO₂e
- Included lunch with mountain views + snacks & bottled water (tourism-level portions and waste): 60 kg – higher-impact estimate
Activities & Excursions – 40 kg CO₂e
- Guided cruise, scenic flight, photo stops, wildlife viewing and expert commentary
TOTAL ESTIMATED FOOTPRINT PER PERSON: 420 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset: 2 × 420 kg = 840 kg CO₂e per individual booking
- How: Direct funding of landscape restoration projects – reforestation, mangrove protection, regenerative agriculture, wetland and soil carbon restoration
- Where: Developing countries and regions most affected by climate change (e.g. Pacific Islands, Southeast Asia, Africa, Latin America) for maximum global benefit and community co-benefits
- Why 200% and higher-end estimates: To guarantee coverage despite any measurement discrepancies and to create genuine extra positive impact
Important Notes
- Numbers are deliberately conservative (higher) so we over-deliver on restoration – real footprint may be lower
- The tour already has strong sustainability practices (small group, low-impact visitation in World Heritage area); our independent higher-end analysis adds extra certainty
- Carbon accounting has natural uncertainties – doubling it is the responsible way
- This directly supports long-term carbon-sequestering landscapes and local communities
