A blueprint on energy-efficient buildings will be announced in the first half of this year, Secretary for the Environment KS Wong says.

Mr Wong told the media after attending a radio programme today the public will be encouraged to express their views on how Hong Kong's buildings can save energy.

On the extension of the Environmental Levy Scheme on Plastic Shopping Bags from April, the Government will conduct more publicity programmes to educate the retail trade and the public on the extension, he added.
