About No Air Con Night

A prairie fire can be ignited by a single spark. It is never too late to ease global warming and its environmental impacts!

“No Air Con Night” is a territory-wide energy saving campaign started in 2010 to promote the wise use of air-conditioning. Green Sense aims to bring out the importance in reducing greenhouse gases and saving energy through this event. By turning off the air conditioning for one night, we hope the citizens to  rethink how their habits rapidly affect our natural environment, and take action to slow down global warming.

The use of air-conditioning becomes more frequent while the global temperature is rising year by year. In 2017, the power consumption on air con is 13.6 billion kilowatt hour in Hong Kong which emitted about 7.57 million tonnes of carbon dioxide. Carbon dioxide can cause greenhouse effect and aggravate global warming. In other words, if we rely on turning on air con to cool us down, the weather will be hotter and hotter, which is trapped in a vicious circle. So, the better way to cool down is turning off the air con.

With continuous promotion and educational activities, “No Air Con Night” gained generous support from citizens, the business community, education institutes and political parties. With reference to the pledge collected last year, over 100,000 households joined and turned off the air con at home and hostels. In this year, we aim at 120,000 households joining which can reduce 514 tonnes carbon emission.

We sincerely invite all citizens in Hong Kong to switch off their air con on 5th Oct 2019, suggesting from 7pm to 7am the next day. Make a small step to ease global warming!
