The Government is committed to protecting and enhancing a green environment when planning and designing infrastructural projects. The government had carried out a series of environmental protection and greening works in the planning and design of infrastructure projects. The government has been very active in implementing greening works. In the last five financial years, a total of some 54 million trees, shrubs and annuals have been planted by all government departments in Hong Kong.

     The government will start the preparation for the formulation of Greening Master Plans for the New Territories in late 2009. The Government will strive to increase greening zones, enhance the existing greening areas, and maximize greening opportunities in the planning and development of public works projects.

     Most of the government's infrastructure projects include extensive planting schemes. Such greening works involve planting in a variety of settings like roadsides, footbridges and flyovers, podiums, slopes, river channels and promenades.

     The Architectural Services Department is also actively implementing roof top projects for new government buildings, which aim to help enhance the cityscape and attenuate urban heat islands. Since 2001, about 70 roof top projects for new government buildings have been completed while some 40 projects are under planning or construction. These include schools, office buildings, hospitals, community facilities and government quarters.
     The completion of Road Works at Areas 34 and 52 in Shui Chuen O and Area 56A in Kau To was another milestone in the continual development of Sha Tin New Town. The project provides the essential infrastructure for the housing development and the associated community facilities in the areas which will eventually be developed into communities with pleasant surroundings to accommodate a total population of over 20,000. About 250,000 trees and shrubs will be planted in this project.
