This book provides a detailed breakdown of CO2 emissions from the Australian aviation network. The carbon footprints of scheduled domestic and international aircraft operations are examined from the perspective of both airlines and airports. While the data in the book relates to Australia, the focus is on trialling visualisations and transparency concepts that can be applied in general for the reporting of aviation carbon footprints. The concepts illustrated in the book can be used to paint 'carbon footprint pictures' for any aircraft operations network. The document also demonstrates the robustness of applying great circle carbon footprinting techniques to aviation.
