Chiho Environmental Group and EcoSmart Energy Management Limited had formed a partnership and jointly completed the design and construction of a solar power generation system in Chiho's Hong Kong factory. The system was approved by the Hong Kong CLP, officially launched in February 2021, and successfully completed in May 2021. It is currently the single largest solar power system in Hong Kong. This system will be able to generate 1,013,375 kilowatt-hours of electricity per year (approximately equivalent to the total electricity consumption of 241 Hong Kong households), which is estimated to reduce carbon emissions by approximately 572,000 kilograms per year. The solar power generation system, which is fully financed by EcoSmart and installed on the rooftop of the Chiho's Hong Kong factory, not only will contribute to sustainable development, but also general income from power generation for Chiho. It is believed that this will act as a model to allow other Hong Kong companies and organizations to understand the benefits of utilising the roof space for solar power systems and encourage them to work together to tackle global climate change.
