Carbon Footprint & Offset Report: Wilsons Prom Whale Cruise
Quick Snapshot
Estimated CO₂e footprint per participant: 95 kg CO₂e
(higher-end conservative estimate – covers all on-tour impacts plus average local travel to/from Port Welshpool Jetty)
Our 200% offset commitment per booking: 190 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
- 6-hour scenic whale watching cruise
- Departs Port Welshpool Jetty (80 Lewis Street, Port Welshpool VIC) at 10:30am
- Stable passenger vessel with undercover seating
- No accommodation included
- Meals: Morning tea, homemade lunch, afternoon snacks + complimentary tea and coffee
- Highlights: Spot migrating humpback and southern right whales (90% expected sightings), dolphins frolicking alongside the boat (90% expected), Australian & New Zealand fur seals in natural habitat, seabirds (White Bellied Sea Eagles, Shy Albatross, Australasian gannets); learn about area history and marine life
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: 6 hours
- Key locations: Port Welshpool Jetty start/end, open waters of Bass Strait along the east coast of Wilsons Promontory
- Travel style: Scenic whale watching cruise with wildlife viewing and commentary
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to Port Welshpool Jetty is factored into the higher-end footprint for completeness. Operates mid-July to November (whale migration season).
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 marine cruise operations and onboard catering.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. bar purchases).
Detailed Emissions Breakdown (per participant)
Transportation – 45 kg CO₂e
- Average local travel to/from Port Welshpool Jetty (higher-end mix): 25 kg
- All on-tour passenger vessel cruise (6 hours, shared): 20 kg – higher-end marine diesel factor
Accommodation – 0 kg CO₂e
- Cruise only – no overnight stay
Meals & Food – 30 kg CO₂e
- Morning tea, homemade lunch, afternoon snacks + tea/coffee: 30 kg – higher-impact estimate including production and waste
Activities & Excursions – 20 kg CO₂e
- Scenic cruise, whale/dolphin/seal viewing, seabird spotting and commentary
TOTAL ESTIMATED FOOTPRINT PER PERSON: 95 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset:2 × 95 kg = 190 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 (focus on marine habitat education and responsible whale watching); 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
