Frankfurt is green in lots of other ways, too! In fact, for its combined focus on the planet, people and profit, Frankfurt earned the top spot as the world’s most sustainable city in 2015, and has consistently ranked in the top 10 since then. It has also got lots of fun local eco initiatives, like rooftop bees (and honey!) at the Museum MMK for Modern Art. Finally, we were delighted to learn that Messe Frankfurt, the location for this year’s me Convention, is partially powered by solar panels. Better yet? They are committed to using only renewable energy by 2020.
