THE Government's environmental advisory committee has been re-named, given broader terms of reference and had its membership expanded to include all the major green groups. The move has been welcomed by the environmental groups who had lobbied for a stronger role. The former Environmental Pollution Advisory Committee, or EPCOM, is now known as the Advisory Council on the Environment, or ACE, and its membership was announced yesterday. The World Wide Fund for Nature will have a seat on the council for the first time, as will the Director of Agriculture and Fisheries, in recognition that conservation issues will be addressed. The committee has been boosted by two, to 17 members. Unlike EPCOM, ACE's terms of reference will not be limited to outdoor pollution but will take in conservation, indoor air quality and any other issues related to the environment. EPCOM previously was barred from discussing non-pollution issues, most prominently when it was told it could not discuss the controversial Shalotung golf course because it was not within its terms of reference. David Melville, executive director of the WWF which focuses largely on conservation and ecology issues, will represent the group on ACE. ''Obviously we're very pleased that EPCOM has had its brief expanded so it is not only addressing pollution issues, and we're looking forward to contributing to ACE in its expanded format,'' he said. Green groups also were given permanent membership for the first time, rather than having members sit in their personal capacity. The old system caused complications for Friends of the Earth whose former director, Linda Siddall, stepped down from Epcom last year, leaving them with no voice on the committee. Lisa Hopkinson, who will now represent the group on ACE, yesterday said they had been pressing for wider public consultation and giving the green groups a permanent role on the committee was a step towards this. Green Power and the Conservancy Association also are represented on ACE, as are the Chinese Manufacturers' Association, the Hong Kong General Chamber of Commerce, the Federation of Hong Kong Industry and the Motor Traders' Association. The committee will continue to be chaired by Professor Wang Gungwu, who has headed EPCOM since 1989, even though he has decided to return to Australia late next year. He could not be reached yesterday. A government spokesman said Professor Wang could be expected to serve for at least a year and there was no need to replace him at this time. ACE's other members include legislators Christine Loh Kung-wai, Albert Chan Wai-yip, Dr Samuel Wong Ping-wai and Peggy Lam Pei Yu-dja, who were all re-appointed; Henry Chiu Sin-sing of the Hong Kong Productivity Council; Lam Kin-che of Chinese University; Dr Richard Jack of China Light and Power; and, in their personal capacities, businessmen Chan Kwok-wai and Paul Fan Chor-ho.
