Carbon Footprint & Offset Report: Milford Sound Day Tour from Queenstown
Quick Snapshot
Estimated CO₂e footprint per participant: 380 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: 760 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
- 13-hour full-day tour (hotel pickup early morning, return late afternoon/evening)
- Small group (comfortable minibus)
- Starts and ends with hotel pickup/drop-off from Queenstown accommodations
- Modern air-conditioned minibus + boutique Milford Sound cruise
- No accommodation included
- Meals: Picnic lunch with local produce, snacks & refreshments
- Highlights: Scenic Milford Road with stops (Mirror Lakes, Eglinton Valley, Lake Gunn, Homer Tunnel), boutique cruise with views of Mitre Peak, towering cliffs and waterfalls, wildlife spotting (seals, dolphins, birds), relaxed pace with photo stops
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: 13 hours
- Key locations: Queenstown hotel pickups, Milford Road (Mirror Lakes, Eglinton Valley, Homer Tunnel), Milford Sound (boutique cruise)
- Travel style: Premium small-group day tour with scenic drive and intimate cruise
- 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 any connecting flights, well-to-tank fuel effects, +20% uncertainty buffer, and conservative assumptions for long scenic minibus + marine cruise operations.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. souvenirs or optional scenic flight return).
Detailed Emissions Breakdown (per participant)
Transportation – 280 kg CO₂e
- Average local travel to/from Queenstown pickup points (higher-end mix of car, taxi or short transfers): 30 kg
- All on-tour modern minibus transfers (~480 km round trip, shared small group) + boutique cruise: 250 kg – higher-end diesel + marine factor with low-occupancy buffer
Accommodation – 0 kg CO₂e
- Day tour only – no overnight stay
Meals & Food – 60 kg CO₂e
- Picnic lunch with local produce, snacks & refreshments (tourism-level portions and waste): 60 kg – higher-impact estimate
Activities & Excursions – 40 kg CO₂e
- Scenic stops, boutique cruise, wildlife viewing and commentary
TOTAL ESTIMATED FOOTPRINT PER PERSON: 380 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset: 2 × 380 kg = 760 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 minibus, boutique cruise, respectful visitation in Fiordland National Park); 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
