THE second annual Business and Industry Environment Week has one primary objective - to create a positive private sector attitude towards the environment. ''We want to develop a business culture that includes environmental considerations automatically, not as optional extras,'' said Mr Stephen Lam Wing-hong, executive director of the organising body, the Centre of Environmental Technology (CET). ''We want to see industry taking a pro-active role and initiating programmes of its own, not merely obeying government regulations,'' he said. ''CET hopes this week of wide-ranging seminars and workshops will champion this notion.'' Issues that will be addressed over the eight sessions will include the design and implementation of environmental management systems, Hongkong's existing Government environmental policy and the current policy review, the role of the media, and the emergence of a whole new industry supplying the relevant technology. Senior members of Legco, the Environmental Protection Department, leading industrialists, academics and journalists will be invited to use the forum to ''hot house'' their ideas and opinions. The keynote speech at the opening ceremony will be given by Hongkong's Governor, Mr Chris Patten, who is a former Secretary of State for the Environment in Britain. Mr Lam, who holds a PhD in environmental engineering in the United States, was born in Hongkong, but spent 25 years in the US. In Louisiana, he became the first Chinese-American to serve at cabinet level in the state government, as a minister for urban development and community affairs. He was also executive assistant to the state governor, advising on international developments. Having run his own environmental consultancy in New Orleans, he returned to Hongkong just 18 months ago, to head the CET from its creation in October 1991. Mr Lam said he was committed to his cause but, should his enthusiasm ever temporarily wane, he needed only to gaze up at the artwork on his office wall where the Chinese calligraphy read, ''Protect the Environment and Benefit Mankind''. This simple message serves as a beacon of hope for him because it was hand-painted by China's Minister for the Environment, Professor Qu Geping, and was presented to Mr Lam in Beijing in May last year, in recognition of his work. Mr Lam is well aware that he has a huge task on his hands. Not only must he encourage Hongkong's business and industrial communities into environmentally sound practices, he also wants to extend what he himself describes as an ''evangelistic mission'' into China. One positive sign is that Professor Qu is due to speak in one seminar on the subject of ''Entrepreneurial Opportunities: Public/Private Partnerships''. The CET is the first and only privately initiated agency in Asia, working to develop projects that protect the environment. Originally it had a staff of three, based in 2,000 square feet of space at the City Polytechnic of Hongkong. But it now has eight staff, with a further two appointments pending. Planning is underway for a move to 40,000 sq ft of premises, with the objective of making CET the undisputed regional environmental information and resource centre. A site has been earmarked. The new building is expected to feature an exhibition hall with a foyer display area, where environmental technology and pollution control equipment can be showcased. An auditorium, meeting and conference rooms and a computer database centre, with technical and support facilities, are also planned. Mr Lam said extensive landscaping, together with state-of-the-art energy efficiency technology, would make the centre a showpiece for Hongkong's burgeoning environmental awareness.
