Local action has always been at the heart of environmental progress. Especially now, local action is necessary to combat climate change. Cities, rightly seeing electric as one of the big climate solutions, are clearly at the forefront.
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.
The IMO will consider concrete proposals on ways to reduce the risks of HFO at the next meeting of its Marine Environment Protection Committee, MEPC 72 in April 2018. A decision on what should be done to mitigate the risks of HFO could come as early as 2019.
The messages on cost, greenhouse gas emissions, and latitude in interpreting the statute may not be entirely consistent, but one thing is clear: U.S. EPA is now intent on dialing down RFS obligations, and that is a real change.
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.
