Climate change is an inevitable challenge for the world. If mitigative measures are not taken promptly, frequent extreme weather events will occur along with sea-level rise, threatening food supply and global species. Therefore, immediate reduction in carbon emission is needed in order to mitigate climate change!

Electricity generation is the major source of carbon emission in Hong Kong. When generating electricity, fossil fuel is burned, releasing numerous greenhouse gases, hence, exacerbating climate change. According to the EMSD of the Hong Kong government, on average, more than 30% of electricity generated is wasted on air conditioning every year, where the value could reach 60% in the summer. Use less and use the aircon wisely is crucial to reducing our carbon emission.
