The caretaker government plans to ban two-stroke vehicles in all the district headquarters and metropolitan cities to reduce greenhouse gas emissions that contribute to hazardous global warming. "Government is thinking about making cities and district towns clean by getting rid of two-stroke engine as it causes massive air pollution,' Raja Devasish Roy, special assistant to chief adviser on Chittagong Hill Tracts (CHT) and Forest Affairs, told UNB. He said the government will take steps to create awareness among the people against the use of two-stroke engines. Earlier, two-stroke engines were banned from the capital city of Dhaka and port city Chittagong. Raja Devasish, who had a meeting with Japanese Ambassador Masayuki Inoue, said the envoy sought Bangladesh's support in tackling climate change a red-hot issue that is going to be raised at the G8 summit to be held in Japan. The ambassador said Japan's government is willing to assist Bangladesh for adaptation and mitigation from the adverse impact of the changes in climate, which is already putting the country in perils -- like droughts, floods and cyclones.
