In this episode, we welcome back Dan Rutherford, Senior Director of Research at the International Council on Clean Transportation (ICCT), for his second appearance on the show. Rutherford shares his insights on the latest developments, partnerships, and challenges in reducing aviation emissions and achieving net-zero emissions by 2050.Rutherford discusses ICCT's expanded collaborations with industry partners, governments, and non-governmental organisations to apply their research directly to various projects and initiatives aimed at reducing aviation emissions. He highlights their work with Google on the Travel Impact Model (TIM), which aims to provide consumers with accurate, precise, and transparent emissions estimates when booking flights.The conversation delves into the challenges of achieving net-zero emissions by 2050, with Rutherford providing sobering projections and emphasises the critical role of sustainable aviation fuels (SAFs) in bridging the gap, given the long lifespan of aircraft and the slow development of alternative technologies like hydrogen.The discussion also touches on the concept of a frequent flyer levy as a potential progressive taxation method to fund the transition to net-zero emissions. Rutherford emphasises the importance of consumer awareness and action in driving change within the aviation industry. The conversation concludes with Rutherford highlighting the role of multi-stakeholder initiatives and partnerships between organisations like ICCT and airlines, manufacturers, and other industry players in driving the transition to a cleaner, more sustainable future for aviation.If you LOVED this episode you’ll enjoy revisiting one of our earliest episodes – also with Dan – who sets the stage for understanding the future of sustainable aviation and the trajectory airlines and governments need to follow to get to net-zero emissions.
