In many ways, Essen is the envy of cities trying to move past their industrial days. Once the steel and coal center of Germany, Essen’s economic success in the early 20th century was evident in the dust blanketing the city and sulfur filling the air with the constant stench of rotten eggs.

Speakers included representatives from Pittsburgh, Cincinnati, and Beijing’s E-Town (short for Economic-Technological Development Area)—all cities that make up the new Urban Transitions Alliance.
