Carbon Footprint & Offset Report: Phillip Island Seal Cruise
Quick Snapshot
Estimated CO₂e footprint per participant: 65 kg CO₂e
(higher-end conservative estimate – covers all on-tour impacts plus average local travel to/from Cowes Jetty)
Our 200% offset commitment per booking: 130 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
- 2-hour scenic coastal cruise (departs 2:00pm daily all year; extra departures in peak periods)
- Boat capacity not specified (small-group friendly)
- Departs and returns to Cowes Jetty, Phillip Island (11-13 The Esplanade, Cowes VIC)
- Stable passenger vessel with undercover viewing
- No accommodation included
- Meals: Complimentary afternoon/morning tea + cake served on return
- Highlights: Australia’s largest fur seal colony (average 5,000+ seals sighted up close); seals approach the boat; playing with seaweed, diving, prey-chasing; moulting process; seabirds (crested terns, sooty oystercatcher); learn about marine mammals and habitat; beautiful Phillip Island western shoreline
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: 2 hours
- Key locations: Cowes Jetty start/end, Seal Rocks (2 km off rugged southwest coast of Phillip Island)
- Travel style: Relaxed seal-watching scenic cruise with close wildlife encounters
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to Cowes Jetty 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 well-to-tank fuel effects, +20% uncertainty buffer, and conservative assumptions for short marine cruise operations and complimentary onboard refreshments.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. bar purchases).
Detailed Emissions Breakdown (per participant)
Transportation – 40 kg CO₂e
- Average local travel to/from Cowes Jetty (higher-end mix of car, taxi or short transfers): 25 kg
- All on-tour passenger vessel cruise to Seal Rocks (2 hours, shared): 15 kg – higher-end marine diesel factor
Accommodation – 0 kg CO₂e
- Cruise only – no overnight stay
Meals & Food – 15 kg CO₂e
- Complimentary tea/coffee + cake on return: 15 kg – higher-impact estimate including production and waste
Activities & Excursions – 10 kg CO₂e
- Scenic cruise, close seal encounters, seabird viewing and onboard interpretation
TOTAL ESTIMATED FOOTPRINT PER PERSON: 65 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset:2 × 65 kg = 130 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 mammal habitat education, no motor craft interference with seals); 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
