The Environmental Protection Department will launch a fashion show in June to mark World Environment Day 2007 and promote dressing-down in the workplace.

Chief Executive Donald Tsang will officiate at the Cool Biz Fashion Show with senior officials, business representatives and consulate-generals. A television programme featuring the show will be aired on TVB-Jade on June 9 at 9.30pm.

Meanwhile, the department and the Environmental Campaign Committee will work with the 18 district councils to appeal to the public to dress-down at work and conserve energy.

The slogan for World Environment Day 2007 is "Melting Ice: a Hot Topic?", which focuses on the effects of climate change on polar ecosystems and communities, and the ensuing consequences around the world. To echo this global theme, Clean Air is set as the local theme to promote energy saving and dressing-down in the workplace.

In Hong Kong, one billion units of electricity can be saved yearly if the air-conditioned room temperature is set three degrees Celsius higher in all air-conditioned premises. Emission of carbon dioxide will be cut by 700,000 tonnes, sulphur dioxide 2,400 tonnes, nitrogen oxides 1,200 tonnes and respirable suspended particulates 100 tonnes.
