When You Book With Zero Trace
Quick Snapshot
Estimated CO₂e footprint per participant: 420 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: 840 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: 4 days / 3 nights
- Key locations: Melbourne start, Great Ocean Road (Bells Beach, 12 Apostles, Loch Ard Gorge, Great Otway National Park), Warrnambool, Tower Hill, Port Fairy, Cape Bridgewater, Mount Gambier, Coonawarra, Naracoorte Caves, Hahndorf, Mt Lofty Summit, Adelaide end
- Travel style: Small-group eco-tour with guided walks, scenic drives and wildlife/cultural 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 coach operations and tourism-level meals.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. souvenirs or optional dinners).
Detailed Emissions Breakdown (per participant)
Transportation – 220 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 coach transfers (~1,200 km total, shared small group): 195 kg – higher-end diesel factor with realistic low-occupancy buffer
Accommodation – 135 kg CO₂e
- 3 nights comfortable motels: 45 kg per night – higher-end for regional energy, heating and laundry
Meals & Food – 45 kg CO₂e
- 4 days of included breakfasts/lunches + own dinners/snacks: ~11 kg per day – higher-impact estimate
Activities & Excursions – 20 kg CO₂e
- Guided walks, national park entries, winery tasting, caves visit and commentary
TOTAL ESTIMATED FOOTPRINT PER PERSON: 420 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset: 2 × 420 kg = 840 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
