Freiburg - the Green City
Freiburg’s journey as a “Green City” is defined by numerous milestones. The city’s environmental movement began in 1975 with the sucesful citizen-led opposition to the planned Wyhl nuclear power plant, paving the way for sustainable policies. In 1979, Freiburg built its first solar apartment building, followed by the establishment of the Fraunhofer Institute for Solar Energy Systems (ISE) in 1981, a global leader in solar energy research.
In 1986, Freiburg’s municipal council passed a groundbreaking resolution to phase out nuclear energy, alongside the creation of the Environmental Protection Department, reinforcing the city’s commitment to a cleaner future. In 1994, Freiburg further innovated with the construction of the Heliotrop, the world’s first plus-energy house. The Vauban district, initiated in 1998, became a global model for sustainable urban development with its car-free zones and energy-efficient designs.
Freiburg also became a center for renewable energy events, hosting the premiere of the "Intersolar" fair in 2000, which later evolved into the globally recognized innovation platform, "The Smarter E." In 2014, Freiburg set bold climate targets, including a 50% reduction in CO2 emissions by 2030 and climate neutrality by 2050. The launch of the “Green Industry Park” initiative that same year underscored Freiburg’s push to involve businesses in sustainability.
In 2021, Freiburg updated its climate neutrality goal to 2038 and launched a €120-million Future Fund to support green projects. For its achievements, the city was honored with the German Sustainability Award as Germany's most sustainable major city.
These milestones highlight Freiburg’s leadership in environmental innovation and its ongoing dedication to sustainable living.
Freiburg - at the heart of the Black Forest
The Black Forest (Schwarzwald) in southwestern Germany is renowned for its natural beauty, deep cultural roots, and progressive environmental efforts. Historically, it has been a source of legends, crafts like cuckoo clock making, and traditional Black Forest houses that harmonize with the landscape.
Culturally, the Black Forest has influenced folk art, cuisine (such as Black Forest ham and cake), and festivals. It also played a pivotal role in forestry and woodcraft traditions.
Today, the Black Forest embraces sustainability, exemplified by its renewable energy projects. The region hosts Germany's largest solar park in Freiburg, wind farms, and sustainable forestry programs. Villages like Freiamt are nearly energy self-sufficient, combining wind, solar, and biogas installations.
As a UNESCO Biosphere Reserve, and with it's own national park, the Black Forest highlights eco-tourism, promoting conservation alongside its cultural heritage. This blend of tradition, innovation, and ecological stewardship makes it a symbol of sustainable living.
