Hong Kong's air quality continues to deteriorate due to pollution, with emissions generated by the electric power stations accounting for 80% of the smog. Greenpeace hopes to raise public awareness of this issue.

Light switches designed as a nose were distributed and installed in partnering corporations, retailers and restaurants. When the switch is turned off, the nostrils will emerge, implying that the nose can now take a breath of fresh air; when the switch is turned on however, the nostrils are hidden within the switch, implying that the nose can no longer breathe. This educates users that reducing the use of energy can bring fresher air for all to breathe.

A lot of the corporations, retailers and restaurants have already installed these light switches. It was noted that more of their staff/customers are willing to switch off the lights after use.
