To enhance the co-ordination among concerned departments and the community, a high-level Steering Committee on Greening (SCG) was established in December 2002 to set the strategic direction and oversee the implementation of major greening programmes. Since the establishment of the Greening, Landscape and Tree Management Section in the Development Bureau in 2010, the SCG has been reorganised and renamed as Steering Committee on Greening, Landscape and Tree Management (SCGLTM). This steering committee is chaired by the Permanent Secretary for Development (Works) with members drawn from 16 bureaux and departments.

Various committees were set up under SCGLTM (for more details, please enter). They are responsible to provide technical and administrative support, as well as to collate input from the general public and expert advisers. In addition, they will have regular meetings to promote greening, review the existing standards and guidelines on greening, and establish reference guidelines for maintenance of trees and vegetation.
