The seventh issue of our sustainability newsletter project was published a week and a bit ago, and is mostly about sustainable travel and transport...

Things I learned writing articles in this issue

* Sometimes, like crossing an ocean, flying is actually the most sustainable transport option (as well as the cheapest).

* Hydrogen fuel cell cars might not be as popular or in the news as Tesla and other electric options, but if you live in a place with the infrastructure; Japan, Germany, California, etc. then they are a much better option.
