Carbon Footprint & Offset Report: Katherine Gorge Tour & Edith Falls
Quick Snapshot
Estimated CO₂e footprint per participant: 160 kg CO₂e
(higher-end conservative estimate – covers all on-tour impacts plus average local travel to/from Darwin pickup points)
Our 200% offset commitment per booking: 320 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
- 13.5-hour day tour (departs ~6:00am, returns ~8:00pm)
- Group size 8–28 travellers (usually max 21)
- Starts and ends at selected Darwin inner-city pickup points (main central point: Travelodge Resort Darwin / The Leea Darwin)
- Air-conditioned mini-coach (~820 km round trip)
- No meals or accommodation included
- Highlights: Guided commentary en route, Nitmiluk Visitor Centre (Jawoyn-managed cultural displays), 2-hour NitNit Dreaming Katherine Gorge boat cruise through 70 m cliffs, Edith Falls (Leliyn) for seasonal swimming in plunge pools or relaxing, guided bush walks (~1–2 km, rocky terrain), wildlife spotting
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: 13.5 hours (full day)
- Key locations: Darwin CBD pickups, Stuart Highway via Adelaide River/Pine Creek, Nitmiluk National Park (Nitmiluk Visitor Centre, Katherine Gorge boat cruise, Cahills Crossing), Edith Falls (Leliyn)
- Travel style: Eco day tour with boat cruise, short guided walks and cultural/wildlife focus
- Assumptions: Average participant, standard behaviours, higher-impact choices where uncertain. Local travel to Darwin 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 remote Northern Territory mini-coach operations, marine boat cruise and tourism-level food purchases.
- Per person, full tour experience.
- Excludes only purely personal extras (e.g. souvenirs or optional extra activities).
Detailed Emissions Breakdown (per participant)
Transportation – 105 kg CO₂e
- Average local travel to/from Darwin pickup points (higher-end mix of car, taxi or short transfers): 30 kg
- All on-tour air-conditioned mini-coach transfers (~820 km round trip, shared): 75 kg – higher-end diesel factor with realistic low-occupancy buffer
Accommodation – 0 kg CO₂e
- Day tour only – no overnight stay
Meals & Food – 25 kg CO₂e
- No meals included; higher-end estimate for own purchases at stops (Adelaide River, Pine Creek or Nitmiluk Visitor Centre) with tourism-level portions and waste: 25 kg
Activities & Excursions – 30 kg CO₂e
- 2-hour NitNit Dreaming boat cruise, guided bush walks (~1–2 km), wildlife spotting, cultural displays at Nitmiluk Visitor Centre and commentary
TOTAL ESTIMATED FOOTPRINT PER PERSON: 160 kg CO₂e
Our 200% Offset Commitment
- Amount we will offset:2 × 160 kg = 320 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 impact guidelines, respect for Jawoyn traditional owners, stay on designated tracks, support local economy, refillable water encouraged); 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
