Climate change impacts the world we live in today as well as future generations. As with other transportation sectors, aviation plays a role in sustainability. The Federal Aviation Administration (FAA) is rolling out Phase III of its Continuous Lower Energy Emissions and Noise (CLEEN) Program, working with stakeholders to decrease aviation's effects on climate change. Among other things, Phase III of the CLEEN Program introduces new environmental goals, including reducing noise and carbon dioxide (CO2) emissions. Tune in to this podcast episode where we sit down with Kevin Welsh, FAA's Executive Director of the Office of Environment & Energy, and David Hyde, former Director of Environmental Policy at the Aerospace Industries Association, to discuss what CLEEN is, what success looks like, and what is exciting about this new phase.
