When You Book With Zero Trace
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 San Remo 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
- 3-hour scenic cruise (departs San Remo Jetty daily at 1:00pm; returns ~4:00pm)
- Passenger vessel (group-friendly; subject to minimum numbers and weather)
- Departs and returns to San Remo Jetty (170 Marine Parade, San Remo VIC 3925)
- No accommodation included
- Meals: Afternoon tea (cake & biscuits) + complimentary tea & coffee; licensed bar (drinks at own expense)
- Highlights: Search for migrating humpback & southern right whales (85% expected sightings) and dolphins (80% expected); seals & seabirds (Shy Albatross, Australasian gannets); cruise past Cape Woolamai cliffs & caves; watch behaviours like breaching, tail slapping, spy-hopping; captain’s commentary on marine life & local history
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: 3 hours
- Key locations: San Remo Jetty start/end, open waters of Bass Strait along Phillip Island’s southern coastline & Cape Woolamai
- Travel style: Relaxed dolphin & whale watching cruise with close wildlife encounters and commentary
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to San Remo Jetty is factored into the higher-end footprint for completeness. Seasonal: June–early August (2026 season starts 4 June).
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 San Remo Jetty (higher-end mix of car, taxi or short transfers): 25 kg
- All on-tour passenger vessel cruise (3 hours return, shared): 15 kg – higher-end marine diesel factor
Accommodation – 0 kg CO₂e
- Cruise only – no overnight stay
Meals & Food – 15 kg CO₂e
- Afternoon tea (cake & biscuits) + complimentary tea & coffee: 15 kg – higher-impact estimate including production and waste
Activities & Excursions – 10 kg CO₂e
- Scenic cruise, whale/dolphin/seal viewing, seabird spotting and captain’s commentary
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 (responsible marine wildlife viewing from a distance, educational commentary on habitat protection); 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
