Carbon Footprint & Offset Report: Hervey Bay Half Day Whale Watching Tour
Quick Snapshot
Estimated CO₂e footprint per participant: 145 kg CO₂e
(higher-end conservative estimate – covers all on-tour impacts plus average local travel to/from Hervey Bay pickup points)
Our 200% offset commitment per booking: 290 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
- 4-hour guided catamaran cruise (morning or afternoon departures)
- Comfortable groups (max ~85 passengers)
- Starts and ends at Great Sandy Straits Marina, Hervey Bay (free hotel transfers from select Hervey Bay accommodations)
- No accommodation included
- Meals: Two light meal services (morning or afternoon tea outbound and antipasto-style platter on return)
- Highlights: Close humpback whale encounters (breaching, tail slapping, spy hopping), water-level viewing platform, expert naturalist guide, underwater hydrophone for whale song, potential dolphins and turtles
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: 4 hours
- Key locations: Hervey Bay Marina start/end, sheltered waters along western side of K’gari (Fraser Island)
- Travel style: Guided eco catamaran whale watching cruise
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to Hervey Bay pickup points is factored into the higher-end footprint for completeness. Operates during humpback migration (July–late October).
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 well-to-tank fuel effects, +20% uncertainty buffer, and conservative assumptions for short marine catamaran operations.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. souvenirs or additional purchases).
Detailed Emissions Breakdown (per participant)
Transportation – 80 kg CO₂e
- Average local travel to/from Hervey Bay pickup points (higher-end mix of car, taxi or short transfers): 25 kg
- All on-tour fast catamaran cruise (shared group): 55 kg – higher-end marine diesel factor
Accommodation – 0 kg CO₂e
- Day tour only – no overnight stay
Meals & Food – 40 kg CO₂e
- Two light meal services (tea + antipasto platter) (tourism-level portions and waste): 40 kg
Activities & Excursions – 25 kg CO₂e
- Guided whale watching, naturalist commentary, hydrophone use and wildlife viewing
TOTAL ESTIMATED FOOTPRINT PER PERSON: 145 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset: 2 × 145 kg = 290 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 (eco vessel, naturalist guide, respectful whale viewing); 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
