Abstract

The civil aviation sector has been forecast to grow at the rate of 4.5% per year for the foreseeable future. There are increasing concerns about the impact of aircraft emissions on local air quality, health, and climate change. Aircraft engines are a unique source of emissions both at ground level in the urban environment and at cruise level altitudes. The characteristics of aircraft engine emissions are distinct from other sources, and have been shown to vary with engine type, fuel composition, and engine thrust setting. The aviation industry has committed to reducing emissions through technology, operations, and infrastructure improvements, and the use of sustainable alternative jet fuels (SAJF) and market-based measures, with an ambitious target of 50% reduction in carbon emissions by 2050 from 2005 levels. A number of potential pathways are being pursued to produce SAJF and blending components from various feedstocks. SAJFs must be compatible with existing aircraft engines and fuel handling and storage infrastructure to be considered “drop in” fuels. Several evaluations and flight demonstrations of SAJFs blended with conventional jet fuel have been performed. Aircraft engines burning SAJFs have shown significant reductions in their PM emissions, and modest reductions for gaseous emissions. A summary of recent measurements to characterize the gaseous and non-volatile particulate matter (nvPM) emissions from aircraft engines burning conventional jet fuel and SAJFs will be presented. The development of a new international regulatory standard for nvPM emissions from civil aviation aircraft engines will also be discussed in the context of changes in jet fuel composition.

Speaker

Dr. Prem Lobo is the Team Leader for the Black Carbon Metrology group in the Metrology Research Centre at the National Research Council Canada. He is an international expert on aviation-related emissions characterization and regulatory standards development. He specializes in the assessment of aircraft engine emissions generated utilizing conventional and alternative aviation fuels, and their impact on local air quality and climate change. Dr. Lobo is a nominated member of the International Civil Aviation Organization’s Committee on Aviation Environmental Protection - Working Group 3 (WG3). In this capacity, he has contributed to the development of the new non-volatile particulate matter (nvPM) emissions regulatory standard for aircraft engines. He is also a member of the Transportation Research Board (National Academies, USA) standing committees on the Environmental Impacts of Aviation (AV030) and Alternative Transportation Fuels and Technologies (ADC80), and is the chair of the Alternative Aviation Fuels subcommittee.
