Greening
As trees grow, they take carbon dioxide out of the air and transform it into their roots and leaves. By providing shade and transpiring water, trees can regulate air temperature and thereby reduce energy use for air conditioning.
Despite Hong Kong's small size and dense population, we have designated 24 Country Parks and 17 Special Areas (11 of which are within Country Parks), with a total area of about 44 000 hectares. About 43% of Hong Kong's land area is under statutory protection. These protected areas have not only contributed to the maintenance of a rich biodiversity, but also help enhance the carbon dioxide absorption capacity in Hong Kong.

Develop Greening Programme
The Government compiles a territory-wide greening programme each year to maximise plantation opportunities. In the past five years, a total of about 8.5 million trees were planted. About 1.2 million plants will be planted in 2010. We will also push ahead with the greening work in densely populated urban areas through various Greening Master Plans.

Identify Greening Opportunities
Apart from planting trees on flat land or slopes, further plantation opportunities are being identified through new techniques. For instance, we aim to implement green roof projects for new Government buildings as far as practicable. Green roofs will be retrofitted at existing Government buildings. Pilot schemes to install vertical green panels at lift towers and external walls will also be carried in public housing estates.

Encourage Community Support and Private Sector Involvement
In addition to actively implementing greening in Government projects, the Government also seeks to promote the greening initiative in the private sector. A consultancy study on sustainable building design which aims to develop relevant guidelines and introduce more green features in buildings is being carried out.
