The Sunshine Coast Airport sought approval for a new runway to accommodate wide body jets. The EIS called for a carbon footprint following ISO14064, the Greenhouse Gas Protocol and the National Greenhouse and Energy Reporting (NGER) scheme, and including scope 3 emissions where possible.
Unusually, emissions from aircraft operations including landing and takeoff, and en route were to be covered. These do not have established estimation methods. Given the complex mix of current and forecast aircraft movements – commercial, general aviation, training flights and helicopter activity – Scott had to create an innovative method.
The base data reconciled multiple data sources for current and forecast movements. We then used Landing Take Off (LTO) emissions and passenger-kilometre factors, but the numerous helicopter and general aviation movements presented more challenges. The team overcame boundary setting, emission factor and data difficulties to produce a robust and defensible assessment. Scott completed this project while with Katestone.
