To facilitate the coordination of environmental work in the Department, the Green Manager’s Committee was formed in 1999, which sets environmental objectives and adopts measures in line with the Government’s environmental policies. The Environmental Auditing Team conducts comprehensive audits at institutions, and reports the findings and makes recommendations to the Committee. Such findings and recommendations will be provided to institutions for reference. Phoenix House and Siu Lam Psychiatric Centre were chosen for conducting comprehensive environmental audits in 2019.
Our environmental initiatives include energy conservation, use of renewable energy, green housekeeping and gradual replacement of conventional electrical appliances and lighting systems with energy saving models. In 2019, two projects for the replacement of aged floodlight systems with LED floodlights and nine projects for the replacement of split-type air conditioners with variable frequency drive types were completed.
The Department has been making its best endeavours in resource utilisation in order to limit wastage and control operational consumption in offices. In 2019, Pik Uk Laundry introduced phosphate-free detergents and started to replace three units of diesel-fired boilers with gas-fired ones. This not only helps protect the ecology but also reduces carbon emission by 14%. Besides, a new series of government office furniture will be fully launched in early 2020 and by then the consumption of wooden material will be reduced by 63%. Moreover, “Smart Laundry” posters are displayed in all laundry workshops of CSD to promote a water conservation culture. CSD conducted carbon audits for 20 correctional facilities from January 1 to December 31 in 2018. The average greenhouse gas emission from these correctional facilities during the period was 0.116 tonnes of carbon dioxide per square metre (Note 1).
The Department has been implementing water conservation measures. Institutional staff members regularly inspect the exposed parts of water pipes for signs of leakage and arrange timely repairs. To better educate staff and persons in custody, the Department has displayed posters and produced videos to promote the message of water conservation. The Department also regularly reviews the washing programme of its laundry workshops to enhance water efficiency. The Chief Executive has announced in her 2018 Policy Address a target of reducing the per capita fresh water consumption by 10% by 2030 at the earliest, using 2016 as the base year. As compared with 2016, the water consumption per capita of the Department was reduced by about 5% in 2018.
