Recruitment of Student Energy Ambassadors for
"Energy Conservation Incentive Scheme for Student Hostels"


In 2023 the University introduced the Energy Conservation Incentive Scheme for Student Hostels (ECIS-SH) with the participation of all CUHK hostel buildings of the Colleges, Postgraduate Halls and I-House. The aim of ECIS-SH is to encourage positive behavioural change among student hostel residents and raise awareness throughout the University of the importance of energy consumption and conservation.

Roles of Student Energy Ambassadors

Student Energy Ambassadors will be nominated by College to initiate publicity, education and/or engagement projects on responsible and smart energy consumption in our student hostels. They will compete for the annual Innovation and Engagement awards (e-certificate with cash prize of $4,000 for each award).  Training on smart energy consumption will be provided.

Registration: Please complete online application by 12:00pm, 5 October 2023 (Thursday). Shortlisted students will be contacted later.

Demo session of dried floral arrangement and making yarns with plant fibres were held. Each participant has taken their art of nature home.

Tree Planting Day

Participants gained valuable knowledge about the significance of planting trees as an effective strategy to restore the damage to ecosystems under SDG #15 (“protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss”) and UN Decade on Ecosystem Restoration 2021-2030.


Self-motivation Fund for Sustainability Activities

Self-Motivation Fund for Sustainability Activities encourages students to participate in various kinds of sustainability activities that promote sustainable development and reduce inequality.


Extract of Students’ Reflections


“As a person who has never practised farming, these activities have inspired me in terms of the difficulties in growing crops and maintaining financial sustainability of a farm in Hong Kong. Apart from the land use conflict between urban development and rural preservation, farmers also face shortages of resources and insufficiency in marketing knowledge. Such insight has enabled me to realise the importance of collective power in order to support the local agriculture system.”

Rooftop Farming

Rooftop Farming is one of our signature initiatives, working closely with Green Team, to engage students in green living. After planting in around October, the harvest in January – April is apparently the most expected and fruitful outcome for all farmers. We take a step beyond that.

To protect and nourish the soil during summer, cover crops like green beans, sunn hemp and sunflowers will be planted on rotational basis. The practice helps maintain the soil structure, improves soil fertility and lower farmers’ reliance on chemical fertilizers. “Put carbon back into soil” is also seen as one of the possible ways in fighting climate change.


Green Team

Green Team is formed by a group of passionate students to promote green living and sustainability. They have closely collaborated with College to implement a variety of activities, programmes and actions ranging from rooftop farming, eco-tours, green workshops and educational campaigns.

Green Actions

Guidelines for Sustainable Event Planning and Management

The following points deserve special attention and can also serve as an action checklist to

facilitate advance planning and duty assignment. Please always refer to the full guidelines

for implementation details and other environmentally-friendly suggestions.

  • Go electronic and reduce paper consumption whenever possible and appropriate;
  • Limit the number of handouts and souvenirs provided;
  • Purchase fair trade or green products, and choose products without excess packaging;
  • Do not provide corsages and, if name badge holders are used, choose reusable ones and collect them after the event;
  • Do away with single-serving bottled water of 1L or below and avoid individually packed beverages and food items;
  • Minimize disposables like dishware and utensils (e.g., by reminding guests to bring their own mugs, lunchboxes and cutlery);
  • Do not use polyfoam meal containers;
  • Help to protect threatened species by not serving or consuming the following food items: shark’s fins, bluefin tuna, black moss, humphead wrasse, Hong Kong grouper and sturgeon caviar;
  • Reduce food waste: avoid buffets, and order a 6-course menu for Chinese banquets;
  • Adopt measures to reduce waste at source, facilitate waste separation and arrange in advance for the collection of recyclables and unconsumed food;
  • Keep air-conditioner temperatures at 25.5oC + 2oC during the summer months;
  • Turn off lights, air-conditioners and equipment after use; and
  • Engage the services of social enterprises which employ the disadvantaged or minorities.

CUHK Waste Management Policy and Guidelines

CUHK's Waste Management Policy, based on a 'waste management hierarchy', emphasizes the '6Rs' principle: Rethink, Refuse, Reduce, Reuse, Repair and Recycle (or Recover).  We accord top priority to waste reduction at source and encourage cyclical use of resources.  Disposal is the last resort.
