Vienna becomes Europe's largest city with fully electric mail delivery

The world's first kilometer-high skyscraper is set to rise by 2028, according to architect Gordon Gill, who has been instrumental in shaping the future of architecture. The project, known as the Jeddah Tower in Saudi Arabia, aims to surpass all previous records in height and redefine modern architectural priorities. While the tower itself would mark a new era in construction, Gill emphasizes that innovation today lies not just in building taller structures but also in transforming existing cities and buildings.

According to Gill, a co-founder of the Chicago-based firm Adrian Smith + Gordon Gill Architecture, the most significant opportunities for innovation in the United States lie in programming cities rather than constructing entirely new ones. He argues that many of the real challenges already exist within the current urban fabric, where existing infrastructure must be adapted to meet evolving needs. This perspective shifts the focus away from purely vertical expansion toward sustainable practices and intelligent use of space.

Gill highlights sustainability as the most crucial aspect of contemporary architecture. He believes that buildings should contribute positively to their environment rather than being mere consumers of resources. This view aligns with growing trends in adaptive reuse, where older buildings are repurposed for new functions instead of being demolished. According to data from the American Institute of Architects (AIA), nearly half of the 125 million buildings in the United States are over 50 years old, presenting vast opportunities for renovation and functional transformation.

Environmental concerns further support this shift. Experts warn that adapting existing structures could avoid up to 75 percent of carbon emissions associated with new construction. The World Green Building Council reports that buildings account for almost 40 percent of global energy-related emissions, much of which comes from both operational use and the production of construction materials. As such, attention is increasingly focused on "upfront" emissions—those generated during the early stages of construction before a building even begins operation—which experts predict could make up nearly half of the total carbon footprint of new construction by 2050.

Gill underscores the importance of preserving and extending the life of existing buildings rather than replacing them. He cites the renovation of the Willis Tower in Chicago as an example, where improvements in energy efficiency and sustainability earned it a LEED Platinum certification. Such projects represent the future of architecture, combining technology, adaptation, and smart management of existing spaces.

In his view, the future of architecture lies not in seeking new opportunities but recognizing the potential already present around us. By focusing on the integration of technology, repurposing, and efficient use of existing structures, architects can address environmental challenges while meeting the demands of modern society.

Meanwhile, in Austria, Vienna has become the largest European city to implement fully electric postal delivery. The Austrian Postal Service has officially completed its transition to electric vehicles, bicycles, and pedestrian deliveries for packages, letters, newspapers, and other mail items. This milestone was marked at Heldenplatz in Vienna, where notable figures including Arnold Schwarzenegger, Austrian Minister of Economy Wolfgang Hattmannsdorfer, and climate commissioner Jürgen Czernohorszky gathered to celebrate the achievement.

Schwarzenegger praised the efforts of the Austrian Postal Service in advancing sustainable logistics and electrifying transportation. He emphasized that electric mobility represents a critical path toward reducing emissions and achieving a sustainable future. Every investment in this sector holds value, and the Austrian Postal Service demonstrates how concrete climate goals can be realized through practical initiatives.

According to company data, more than 1,300 delivery personnel operate daily in Vienna using electric bikes, scooters, and delivery vehicles. Approximately 1,000 vehicles collectively travel about eight million kilometers annually on electric power, reducing annual carbon dioxide emissions by roughly 2,300 tons. To achieve this, the postal service invested 32 million euros in purchasing electric vehicles and developing necessary charging infrastructure.

Wolfgang Hattmannsdorfer highlighted that the project contributes to greater energy independence for the country, as the vehicles are powered by electricity produced from domestic renewable sources. Part of the required energy is generated through solar plants in Vienna and Hagenbrunn, totaling 5.9 megawatts of capacity. The rest is sourced from renewable energy providers across Austria.

Jürgen Czernohorszky noted that this initiative significantly supports the realization of climate goals for Vienna and reduces emissions from transportation. Currently, the Austrian Postal Service operates a fleet of over 6,000 electric vehicles, making it the largest operator of electric vehicles in the country. Fully electric delivery has already been implemented in other Austrian cities, including Graz, Salzburg, and Innsbruck.

Looking ahead, the company aims to achieve completely emission-free delivery across Austria by 2030, ensuring that the final phase of package delivery nationwide becomes entirely free of carbon dioxide emissions. This ambitious goal reflects a broader commitment to sustainability and environmental responsibility, setting a precedent for other countries to follow.
