A GREENER government that uses less energy, protects the countryside, taxes polluters and seeks community input into its policies is promised in a draft review of environmental policy, but it is unlikely to satisfy environmentalists. Few concrete programmes, cost estimates or target dates are included on key issues such as nature conservation and air pollution, for which green groups have been pushing. Water conservation gets only a passing mention even though Hongkong's main water source - Guangdong - is expected to suffer increasing shortages and local water catchment areas are under threat from development. The still-untitled, thick draft, a copy of which was seen yesterday by the South China Morning Post, will be presented in summary form today to the Legislative Council's environmental affairs panel and a final submission made to the Executive Council in late August. It is intended as a progress report of the 1989 White Paper on Pollution and to look at non-pollution issues which the Government is under pressure to address from local green groups and the international community following last year's Earth Summit. Nature conservation and energy each get their own chapter in the 10-chapter review, reflecting the lack of clear initiatives in these areas in the past. For conservation, another 1,000 hectares of green space will be provided in urban areas, a profile of Hongkong's natural environment will be compiled with the World Wide Fund for Nature, and a conservation authority may be established to protect the countryside. But no target dates are included and there are no major additions to the current policy on land use, even though it has resulted in rural degradation and threats to country parks and local wildlife, such as the Chinese white dolphin. Firmer proposals are planned on energy efficiency, which is considered important because burning fuels like as coal and oil contribute to global warming. Advisory notes will be provided to industry and households next year and power companies will be required to look into the issue and report their findings to the Government. An energy tax was also floated but there were no proposals as to what it might be based on or when it would be introduced. Issues from the 1989 White Paper also crop up and air quality - which Secretary for Planning, Environment and Lands Tony Eason last week said was the most pressing pollution problem for Hongkong - was admitted to be poor. ''Many people are exposed to undesirable levels of air pollutants,'' the review said. Pollution in heavy traffic areas exceed government standards by 15 to 40 per cent and some pollutants are expected to increase by 60 per cent by 2001. But there were no new initiatives for tackling the worst source - motor vehicles. The Green Groups United Front, formed in April by the four major environment groups, has pressed for more co-ordination between the environment and transport branches and the review acknowledges the need for that, but offers no ideas on how or when it might be achieved. The front also urged a greener government and the review goes some way to addressing this. An internal government environmental audit study will be completed next year, ''green managers'' appointed in every department by 1995, and more public access to information offered on environmental impact studies of major infrastructure projects. The ''polluter pays principle'', which the administration has been promoting for the past year, is repeated and charges for disposing of sewage, solid waste and chemical waste are due to be introduced from next year. Other initiatives include: The Environmental Pollution Advisory Committee to get expanded terms of reference, more formal representation for green groups and a new name - the Advisory Council on the Environment. Information on the energy consumption of electrical appliances to be published for consumers. The introduction of electric vehicles to be explored.
