Bombardier's new aircraft is mired in trade disputes, and that's creating some uncertainty over Delta Air Lines' order for 75 CS100 planes. But if Delta keeps its eye on the fuel savings it will reap—and remembers that the clean-sheet design CSeries is going to easily meet the ICAO CO2 standard—it will buy those aircraft, and more.
Next year, EPA has the chance to propose an ambitious GHG standard for aircraft to promote low carbon aviation. It alluded to the possibility of going further than the UN’s weak recommendations in the 2016 endangerment finding, where it argued that it would set aircraft standards “at least as stringent as ICAO’s.” Here’s hoping that EPA agrees with Boeing, GE, and, yes, ICCT and goes further than ICAO’s least common denominator standard.
One of the key challenges faced by engine and airframe manufacturers in developing fuel-efficient products is the looming risk that their significant investment will not pay off. The more this risk is lowered, the better the chance that we will see a much-needed improvement of aircraft fuel efficiency. In this final post of the series, we explore ways to lower the risk faced by these risk-averse industry players.
An interview with Dr. Fay Collier, Associate Director for Flight Strategy, Integrated Aviation Systems Program at NASA Aeronautics and a former Project Manager at NASA Environmentally Responsible Aviation (ERA), on NASA’s contribution to technologies already in use on aircraft flying now, the ERA project, and a new NASA initiative to demonstrate these environmentally responsible aviation technologies.  
Richard Golaszewski's insights on what a successful clean-sheet aircraft program looks like—from research and development to sales, what made it successful, and what makes sense for manufacturers and airlines today to repeat that success.
Why real-world aircraft fuel efficiency improvements fell short of ICAO's mid- and long-term fuel burn technology goals for aircraft designs and what can be done to get us closer to achieving them. An interview with Stanford's Juan Alonso.
