One of Sarajevo’s best-kept secrets is that the city was thinking about sustainability decades before environmental protection became a global priority. While the world today focuses on climate action, cleaner energy, and sustainable urban development, Sarajevo was already transforming itself through one of the most ambitious environmental projects in Southeast Europe. It is a remarkable story that few visitors discover, yet it helped shape the modern city that millions know today.
Before Sustainability Became a Global Trend, Sarajevo Was Already Living It
During the 1970s, Sarajevo faced serious environmental challenges. The city struggled with outdated infrastructure, polluted air, an increasingly contaminated Miljacka River, and aging water and sewage systems. The famous Sarajevo fog was often mixed with smoke and soot from coal and heavy fuel, creating difficult living conditions for its residents. Rather than accepting these problems or abandoning its ambitious plans for the future, Sarajevo chose a different path. City leaders, engineers, visionaries, and citizens came together to launch the largest environmental protection project in the history of Yugoslavia.
The project was supported by a 72-million-dollar loan from the World Bank, making it the largest environmental loan ever granted to Yugoslavia at the time. However, financial institutions were only part of the story. Under the leadership and vision of Emerik Blum and Energoinvest, the people of Sarajevo also played a direct role in transforming their city. Citizens voluntarily contributed a percentage of their monthly salaries because they believed in creating a cleaner, healthier, and more modern Sarajevo for future generations.
The results were extraordinary. A new gas pipeline was built across the city, making it one of the largest infrastructure projects in Sarajevo’s history. Water supply and sewage systems were modernized, waste management facilities were developed, and a collector was constructed along the Miljacka River to improve water quality.
Construction affected everyday life. Streets were excavated, infrastructure was replaced, and the city became one enormous building site. Yet instead of seeing these temporary inconveniences as obstacles, many Sarajevans understood they were investing in the city’s future. Long before sustainability became an international buzzword, Sarajevo demonstrated that environmental protection required long-term thinking, public participation, and the courage to invest in change.
These environmental improvements also made it possible for Sarajevo to present itself as a modern, forward-looking city on the international stage. The environmental transformation became one of the foundations for the city’s successful Olympic bid, proving that ecological responsibility and urban development could go hand in hand. More importantly, it showed that Sarajevo was decades ahead of its time in understanding that a city’s future depends on the quality of its environment.
Today, this forgotten chapter is one of the many remarkable stories preserved at Planet Sarajevo – the Museum of Sarajevo Stories. If you are searching for unique things to do in Sarajevo, looking beyond the city’s wartime history, or interested in discovering the innovations and vision that once made Sarajevo one of Europe’s most progressive cities, this story offers a completely different perspective. It reminds us that the greatest transformations often begin with bold ideas, shared responsibility, and the willingness to build a future.
