EMBARQ's Istanbul Project Director Sibel Bulay warns Turkey's business elite that successful development will require more sustainable transportation policies. Speaking to Turkey’s business and political elite at the Turkish Business Council for Sustainable Development’s recent biennial congress, EMBARQ-Istanbul Project Director Sibel Bulay noted that 45% of Istanbul residents spend at least two hours each day commuting, drastically reducing overall efficiency in the city. Bulay warned that this serious traffic congestion, along with transport-related air pollution and green house gas emissions, is undermining Istanbul's economic vitality and quality of life, threatening the city's plans to become a world-class business and cultural center. The high-profile event was the latest in a series of congresses organized biennally by the Turkish Business Council for Sustainable Development (TBCSD) designed to highlight how sustainable practices need not harm businesses’ bottom line.
