Greenhouse Gas Emissions from Marine Tours: A Case Study of Australian Tour Boat Operators
MetadataShow full item record
This paper estimates the overall and per capita energy costs and GHG contributions associated with tour boat operations in Australia, a country with a 35,000 km coastline and world class marine attractions. Using a comprehensive database of Australian tour boat operators, 145 face-to-face interviews or completed postal survey questionnaires and 45 in- situ audits, the overall GHG emissions for this industry sector was estimated conservatively at 70,000 tons CO2-e or 0.1% of the transport sector in Australia, the fastest growing sector in terms of GHG outputs. On average, this translated into an extra 61 kg CO2-e per tourist if their travel itineraries included a trip on a boat with a diesel engine, or 27 kg CO2-e for a trip on a boat with a petrol engine - the equivalent of a single person driving 140 km or 300 km, respectively, in a standard passenger vehicle. Information obtained from Australian tour boat operators, however, indicated a range of technical and operational opportunities for reducing GHG emissions. In the light of Australia's anticipated growth in domestic and international visitors, the importance of reducing tour boat GHG outputs, is stressed.
