While each purchase is unique, there are fundamental factors that should guide sustainable buying choices. The principles outlined below can be applied to nearly all purchase categories, enabling a more environmentally conscious decision-making process.

Say "NO" to unnecessary purchases:

Aim to reduce non-essential acquisitions by carefully evaluating and prioritising needs. Existing resources should be optimised and responsible consumption should be encouraged. Product that doesn’t need to be purchased has the least carbon footprint!
Buying of disposables is one of the many instances of unnecessary purchases, particularly when there are reusable alternatives readily available. Another example to support this principle is forgoing lanyards for event participants, especially when the event is short-lived and there is no long-term need for the lanyards. Organisers may encourage participants to bring their own lanyard or provide digital alternatives to reduce the environmental impact.

Consider total cost of ownership:

Always evaluate the entire lifecycle cost by using costing approach such as Life Cycle Cost Analysis ("LCCA") and Total Cost of Ownership ("TCO"). Considering just the cost of acquisition would not give you an accurate and comprehensive perspective of the actual cost as it often represents only a portion of the overall expenses associated with a purchase.
By evaluating the lifecycle cost, all hidden and/or long-term expenses would immediately be apparent, leading to a more accurate, informed, cost effective and sustainable procurement decision. While the initial purchase price is a significant factor, ongoing cost such as maintenance cost, energy consumption, disposal and potential environmental and social impact, like carbon tax, should be considered.

Source sustainable products:

If purchases are necessary, prioritise sourcing products with credible certifications that validate their environmental, social and ethical standards. Look for recognised eco-labels and/or certifications such as ENERGY STAR, Singapore Green Labelling Scheme ("SGLS"), Mandatory Energy Labelling Scheme ("MELS") and Forest Stewardship Council ("FSC") to ensure sustainable and responsible procurement.

Source from sustainable suppliers:

Establish relationships with suppliers and consider supporting suppliers who are committed to sustainability, ethical practices and environmental responsibility. By patnering with suppliers with strong commitment to sustainability, we aim to create a more sustainable ecosystem and resilient supply chain.

Dispose responsibly:

Our environmental responsibility does not ends with the receipt of purchased item. Support NUS Zero Waste program by prioritising recycling and reusing at the end of the product lifecycle. Minimise waste by ensuring proper disposal methods that reduce environmental impact and promote circularity. Find out what you can recycle in NUS Campus here ^.
