Prime Minister Sheikh Hasina left for Switzerland on Tuesday to participate in the World Climate Conference-3. She took a regular flight of Biman Bangladesh Airlines to London at 8:45am, accompanied by Foreign Minister Dipu Moni, State Minister for Environment Hassan Mahmud, her press secretary Abul Kalam Azad, and daughter Saima Wazed Putul. The delegation was seen off by cabinet ministers, three military chiefs, and other high officials at Zia International Airport. Mahmud stated in the VIP Lounge that Bangladesh would request compensation from countries accountable for climate change. The theme of the five-day summit, which started on Monday and is organized by the World Meteorological Organisation, is 'Better Climate Information for Better Future'. The summit will continue until September 4. Bangladesh is leading the 50-member LDC Group, comprising countries most at risk from the harmful effects of climate change, largely due to emissions from developed nations.
