Carbon Footprint & Offset Report: Melbourne Great Ocean Road & 12 Apostles Discovery Day Tour
Quick Snapshot
Estimated CO₂e footprint per participant: 100 kg CO₂e
(higher-end conservative estimate – covers all on-tour impacts plus average local travel to/from Melbourne pickup points)
Our 200% offset commitment per booking: 200 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 day tour
- Average 35 guests (max 38)
- Starts and ends at selected inner-city Melbourne pickup points
- Modern air-conditioned coach (~500+ km round trip)
- Morning tea and snack included; lunch/dinner at own expense
- Rainforest walk, wildlife spotting, 12 Apostles, Loch Ard Gorge and multiple lookouts
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: Inner-city Melbourne start/end, Great Ocean Road (Memorial Arch, Apollo Bay, Great Otway National Park, Island Archway, Razorback, Loch Ard Gorge, 12 Apostles)
- Travel style: Iconic scenic discovery day tour with easy walks and lookouts
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to pickup 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 (0.06–0.08 kg CO₂e per passenger-km for coach with buffer), plus well-to-tank fuel effects, +20% uncertainty buffer, and conservative assumptions for tourism operations.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. souvenirs or optional alcohol).
Detailed Emissions Breakdown (per participant)
Transportation – 65 kg CO₂e
- Average local travel to/from Melbourne pickup points (higher-end mix): 25 kg
- All on-tour coach transfers (~520 km round trip, shared): 40 kg – higher-end factor with realistic occupancy
Accommodation – 0 kg CO₂e
- Day tour only – no overnight stay
Meals & Food – 15 kg CO₂e
- Morning tea/snack + higher-end estimate for own lunch/dinner purchases: 15 kg – tourism-level portions and waste
Activities & Excursions – 15 kg CO₂e
- Guided rainforest walk, wildlife spotting, multiple lookouts and national park entries with commentary
TOTAL ESTIMATED FOOTPRINT PER PERSON: 100 kg CO₂e (rounded higher for full coverage)
Our 200% Offset Commitment
- Amount we will offset:2 × 100 kg = 200 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; 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
