The campaign urges Hongkongers to turn off air-conditioning whenever the outdoor temperature is below 27 degrees Celsius.

Three tips for avoiding air-con use – click to view.
  1. Place a cooling mat on top of your seat or bed.
  2. Use an electric fan for better ventilation and heat dissipation.
  3. Use curtains, window blinds or other light-proof materials to reduce solar radiation entering your home.

United Nations Secretary General Antonio Guterres confirmed that this July was the planet’s hottest month in the past 120,000 years. Meanwhile, the local Observatory has said that August was Hong Kong’s hottest since records began in 1884.

In Hong Kong, electricity generation and other energy industries accounted for 62.7 per cent of the total greenhouse gas emissions in 2021, a Green Sense press release said last week. Of the city’s electrical output, 31 per cent is consumed by air conditioning, they added.
