Essen, a city in Germany, has undergone a remarkable transformation from an industrial wasteland to one of Europe’s greenest cities. Despite being marred by pollution and industrial activities for over a century, innovative approaches have helped Essen to revamp its image significantly. The city implemented a mix of Blue Green solutions, focusing on water and land-based projects, which led to Essen being declared the European Green Capital in 2017.
One of Essen’s most prominent green projects is the transformation of the Zollverein industrial complex into an eco-park, now a UNESCO World Heritage site. The site, once a coal production facility, now houses museums, biking trails, art installations, and even a winter ski piste. Additionally, Essen has introduced initiatives like a 100km cycling super-highway and nature-walking trails to promote eco-friendly practices and engage the community in appreciating nature.
Essen has also made significant progress in restoring water bodies like the River Emscher, once considered a biologically dead open sewer. After a two-decade clean-up programme, the river now supports over 1,000 fish and animal species, demonstrating a successful turnaround. The city’s commitment to sustainability is further evident in the creation of urban farms, rainwater harvesting projects, and eco-friendly initiatives throughout Essen.
From the creation of green spaces to revitalizing water bodies, Essen’s transformation showcases the positive impact of sustainable urban development. The city’s green-and-blue approach not only benefits the environment and outdoor enthusiasts but also serves as a model for other cities looking to transition from industrial pasts to cleaner, greener futures.
