Carbon Footprint & Offset Report: Melbourne to Adelaide 2-Day Great Ocean Road & Grampians Tour
Quick Snapshot
Estimated CO₂e footprint per participant: 195 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: 390 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.

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 days / 1 night
- Key locations: Melbourne start, Great Ocean Road (Apollo Bay, 12 Apostles, Loch Ard Gorge, Great Otway National Park), Halls Gap, Grampians National Park (Boroka Lookout, Reeds Lookout/Balconies, Mackenzie Falls), Dimboola Pink Lake, Nhill, Bordertown, Adelaide end
- Travel style: Small-group eco one-way tour with guided bush walks, scenic drives and wildlife focus
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to Melbourne pickup points 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 Melbourne-to-Adelaide mini-bus operations and tourism-level meals.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. souvenirs or optional extra tastings).
Detailed Emissions Breakdown (per participant)
Transportation – 105 kg CO₂e
- Average local travel to/from Melbourne pickup points (higher-end mix of car, taxi or public transport): 25 kg
- All on-tour air-conditioned mini-bus transfers (~520 km total, shared small group): 80 kg – higher-end diesel factor with realistic low-occupancy buffer
Accommodation – 45 kg CO₂e
- 1 night in Halls Gap (motel ensuite or eco YHA shared): 45 kg – higher-end for regional energy, heating and laundry
Meals & Food – 25 kg CO₂e
- 2 days of included meals (lunch, dinner with guest participation, breakfast) + snacks: ~12.5 kg per day – higher-impact estimate including production, transport and waste
Activities & Excursions – 20 kg CO₂e
- Guided bush walks (~4 km total), national park entries, lookout stops, wildlife spotting and commentary
TOTAL ESTIMATED FOOTPRINT PER PERSON: 195 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset:2 × 195 kg = 390 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 (minimal ecosystem disturbance, respect for traditional owners, refillable water encouraged, stay on designated tracks, no feeding wildlife, waste management, guest participation in meal prep/clean-up); 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
