The resurrection of supersonic travel and the quest for net-zero carbon emissions

Double the speed, half the time: from NY to London in 3.5 hours.

✈ The global aviation industry produces around 2% of all human-induced CO2 emissions and so sleeper trains are having a comeback.

Also back is supersonic passenger travel, which died out with the retirement of the Anglo-French Concorde in 2003, after 27 years of service.

✈️ “The jets will be net-zero carbon from day one [and] optimized to run on 100 percent sustainable aviation fuel.” But how? Too good to be true? Environmental groups are worried that faster speeds will equal more pollution.

In addition to United, the startup Boom has contracts or memorandum of understanding with Rolls-Royce and the US Air Force. It has raised $240 million in funding and fielded preorders from Virgin Group (which is also working on its own supersonic jet) and Japan Airlines.

✈️ The Solar Impulse project took Bertrand Piccard and Andre Borschberg flying around the world in a Solar Powered Plane without a single drop of fuel. The journey took 505 days to fly 42.000 km at an average speed of about 70 km/h.


🚂 Sustainable travel is getting overnight travel back on track
