The College Thrift Shop which sells used and donated items in good condition for a cheaper fee to encourage reusing over disposal.

 
The Cutlery Bank serves to minimise the use of disposables by providing an avenue for students to borrow cutlery for their consumption of food. The Cutlery Bank has been employed in collaboration with organising teams of various school events to reduce waste generated by providing a sustainable alternative to disposable cutlery.

 
The Butterfly Garden attracts numerous breeds of butterflies and other insects, serving as a hotspot for the school’s biodiversity enthusiasts.

 
The annual Clean & Green Week, our flagship event, which comprises a week of interesting and engaging activities which serve to educate, involve and promote environmental awareness and sustainability within the school. Activities include: exhibitions, social media campaign, and external speaker sharings. 

 
The Aircon Policy which serves to encourage class ownership over their effect on the environment by regulating the aircon usage within the school. The aircon policy enforces a mandatory minimum of classes conducted without using the aircon, and provides added incentives for classes who go the extra mile by awarding prizes to the top three classes who used the least aircon in a month. As such, the aircon policy encourages classes to change their daily lifestyles to be more sustainable for the benefit of the environment. 

The Green Council also participates in numerous ad-hoc events which serve to promote its cause. From creating exhibitions during the School Mid Autumn Festival to raise awareness of excessive wastage during festivities or collaborating with other organisations like the National Parks Board to educate the public of our local flora and fauna, the Green Council gets involved in numerous activities to further its agenda of building a more sustainable and green Hwa Chong. 

 
Greenterest is a largely informal group within Hwa Chong which comprises people passionate in starting their own green initiatives. Some greenterest events include:

First Spring, a student organised camp targeted at individuals interested in starting their own green initiatives. To encourage and empower these individuals to start their green efforts, First Spring comprised activities such as: discussion sessions for like-minded students to share about their intentions and experiences so that they may learn from each other, talks by external speakers experienced in the environment scene, human library with chances to interact with seniors who had started their own green initiatives.
