LeafTracker supports five sustainability certification standards across buildings, products, and water management. Here's what each one means, who governs it, and why it matters.
National Australian Built Environment Rating System
NSW Dept. of Planning, Housing & Infrastructure
Buildings (offices, hotels, apartments, data centres, shopping centres)
Actual operational environmental performance using 12 months of real metered data — not design intent. Covers Energy, Water, Waste, and Indoor Environment Quality.
1–6 star scale. 6 stars = market-leading; 5 stars = excellent; below 3.5 stars = below average.
Unlike design-based ratings, NABERS scores reflect real-world outcomes. A 5-star NABERS Energy rating means the building genuinely operates efficiently, making it a trusted signal for tenants, investors, and government procurement.
WELL Building Standard™
International WELL Building Institute (IWBI)
New and existing buildings, fit-outs, communities, and portfolios
Occupant health and wellbeing across 10 concepts: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, and Community. Each concept includes preconditions (mandatory) and optimisations (points-based).
Bronze, Silver, Gold, or Platinum — determined by the number of optimisation points achieved.
WELL puts people at the centre of building design. As organisations compete for talent and prioritise employee wellbeing, a WELL certification signals a measurable commitment to the health of everyone inside the building.
BCA Green Mark 2021
Building and Construction Authority (BCA)
New and existing buildings in Singapore — residential, commercial, and institutional
Singapore's national green building rating aligned with the Green Building Masterplan 2030. The 2021 edition evaluates five sections: Health & Wellbeing (Hw), Whole Life Carbon (Cn), Resilience (Re), Intelligence (In), and Maintainability (Mt). Each section is worth up to 15 points, giving a maximum total of 75 points.
GoldPLUS (50–64 pts) and Platinum (65–75 pts) for new buildings. In-Operation buildings can also achieve Gold (37–49 pts). There is no "Certified" tier in GM:2021 — GoldPLUS is the minimum. The Energy Efficiency prerequisite must be met regardless of points scored. Maximum possible score: 75 pts.
5 sections × 15 pts each = 75 pts maximum. Earning ≥10 pts in a section awards a Section Badge. Super Low Energy (SLE), Zero Energy, and Positive Energy are separate BCA energy performance programmes — they are not scoring tiers within GM:2021 and require dedicated energy modelling rather than a point score.
BCA Green Mark is mandatory for new buildings above a certain gross floor area in Singapore, making it central to the built environment here. The 2021 refresh shifts focus from energy efficiency alone to whole-of-life carbon impact, and introduces a mandatory Energy Efficiency prerequisite that must be satisfied before any certification is awarded.
Alliance for Water Stewardship International Water Stewardship Standard
Alliance for Water Stewardship (AWS)
Any organisation that uses water in its operations — manufacturing, agriculture, data centres, and more
Most water certifications ask "are you using less water on your own site?" AWS asks a bigger question: "is the water source your whole region shares actually healthy?" To get certified, an organisation must map where its water comes from, show it isn't depleting or polluting that source, and actively work with others — farmers, communities, other businesses — who depend on the same river or aquifer.
Core, Silver, and Gold — Core means you've met the baseline requirements; Silver and Gold mean you're driving meaningful, measurable improvements for the shared water source.
A factory can cut its own water use by 50% and still be part of a water crisis if the river it draws from is being drained dry by everyone collectively. AWS is one of the few standards that tackles this shared-resource problem head-on, which is why it's increasingly required by large multinationals managing supply chain water risk.
Singapore Green Labelling Scheme
Singapore Environment Council (SEC)
Consumer and commercial products sold in Singapore — furniture, cleaning products, building materials, and more
One of Asia's longest-running eco-labelling programmes. A Type 1 Ecolabel (ISO 14024) that certifies products against multi-criteria environmental standards across the full product lifecycle — from raw material extraction through to end-of-life disposal.
Pass/fail certification with periodic renewal. Products display the Green Label mark once certified.
SGLS gives consumers and procurement teams a reliable, independently verified signal that a product meets environmental standards. It is widely recognised in Singapore government green procurement frameworks.
