Published 6 August 2026 –
Sustainability is now core to doing business in Singapore. As green procurement climbs the corporate agenda, sustainability now makes up at least 5 to 10% of tender evaluation criteria across public and private sectors. Singapore businesses that strengthen the quality, transparency, and consistency of their ESG performance are turning sustainability into bottom-line gains and competitive advantage in the growing green economy. What has been missing is a common national standard defining environmental sustainability excellence, and a clear, staged pathway for businesses of any size to get there.
That yardstick has arrived. Technical Reference (TR) 149:2026 Specification for Organisations to Progress Towards Environmental Sustainability Excellence, was launched in May 2026 by Enterprise Singapore through the Singapore Standards Council, in partnership with the A*STAR Singapore Institute of Manufacturing Technology (SIMTech) and the Singapore Manufacturing Federation.
To help businesses make sense of it, ESGpedia and the Singapore Business Federation (SBF) brought together three perspectives at our complimentary webinar on Thursday, 30 July 2026: Hu Ching, Head of the Net Zero Transition Programme Office at SBF, who unpacked the TR 149 requirements under each level; Benjamin Soh, Founder and Managing Director of ESGpedia, who walked through how digital tools turn TR 149 from a checklist into tangible business outcomes; and Darran Ong, Digital (AI) & Sustainability Manager at SPIN Fans, who shared a firsthand account of his company’s sustainability journey.
Below, we share the most important takeaways from the session, including FAQs, and what TR 149 means for Singapore businesses looking to make sustainability their edge.
1. What is TR 149:2026?
As Hu Ching explained, a technical reference is a provisional national standard, and TR 149:2026 is the first to define, in the Singapore context, what it means to be excellent in environmental sustainability. The full document runs 77 pages and is available on the Singapore Standards eShop, but its purpose can be summed up simply: TR 149 is a Singapore sustainability framework that helps organisations assess and progressively improve their environmental sustainability practices. It provides a practical roadmap to guide businesses across different levels of sustainability maturity, strengthening areas such as governance, operations, supply chain management, emissions management, and business competitiveness over time.
Two design choices make TR 149 distinctive. First, it focuses squarely on the environmental pillar of ESG. Second, and most importantly, it is a multitiered approach.
“With ISO 14001, you either have it or you don’t have it, and it is actually quite difficult to get,” Hu Ching shared, describing the two standards as “same, but different”. “TR 149 is not zero or one. There are four levels that allow you to demonstrate your progress along this sustainability journey.”
2. Four maturity levels, five dimensions: Progress over perfection
TR 149 framework’s four maturity levels – Essential, Bronze, Silver, and Gold – map a progressive journey.
Essential signals that an organisation has started on its sustainability journey. Bronze means internally focused efforts are backed by policies and standard operating procedures. Silver requires demonstrating that supplier engagement and product life cycle work have begun. Gold represents environmental sustainability fully incorporated across the organisation and its value chain – a maturity level that demonstrates what sustainability excellence at its highest tier looks like.
Within each maturity level, requirements are assessed across five dimensions:
- People Readiness: the skills and capabilities of the workforce
- Structure: the policies and governance frameworks in place
- Operations: day-to-day performance on sustainability metrics
- Supply Network: engagement with suppliers beyond the organisation
- Product Life Cycle: especially relevant for companies that produce products
The requirements scale sensibly with each maturity level. Take greenhouse gases: at the Essential level, a documented draft GHG policy and measurement of Scope 1 or Scope 2 emissions will suffice. At Gold, organisations must measure Scope 1, Scope 2, and material Scope 3 emissions.
The entry point is deliberately accessible. “It’s not difficult to get Essential, and Singapore organisations really have no excuse,” Hu Ching said. “All the help and resources are there, and you can get Essential for free using the Green 100 platform.”
Green 100 is a national initiative built on TR 149, bringing together “Queen Bee” corporates and their suppliers, and governed by the newly formed Council for a Competitive Climate Transition (C3T), co-chaired by the National Climate Change Secretariat and SBF. SBF will be hosting in-depth Green 100 workshops covering the Green 100 Supplier Registry and how to attain the Green 100 Essential badge, which is linked to the TR 149 Essential level.
3. Why TR 149 matters now: Sustainability is already 5 to 10% of tender criteria
Benjamin set out why the TR 149 framework is so timely. On the public side, the Ministry of Finance has committed to incorporating environmental sustainability requirements into all government procurement by 2028, a key step toward the public sector’s net zero goals. On the private side, sustainability criteria are already embedded in tender requirements, with recent examples requesting GRI-aligned sustainability reports and carbon disclosures. Meanwhile, exporters serving markets like the EU face the Carbon Border Adjustment Mechanism‘s real carbon footprint calculations.
“Sustainability is now 5 to 10% of the evaluation criteria in procurement tenders,” Benjamin noted, “and suppliers who are aligned with these sustainability requirements typically do better.”
Benjamin predicts this trend will only accelerate. Tenders that currently list sustainability requirements could soon evolve to ask for a specific credential: the TR 149 badge.
4. Starting with digital tools: Essential in 15 minutes, then a progressive checklist to Bronze and beyond
For companies wondering how to begin, Benjamin’s message was reassuring: attaining the Essential level takes no more than 15 minutes using free, readily available tools. From there, he walked through a progressive 10-step checklist towards the higher levels, and stressed that it is not meant to be completed in one shot.
“Companies should not feel overwhelmed,” he shared. “A lot of the basic starting requirements are things you are already tracking. Any operating company typically already knows its energy usage, water usage, and waste disposal. It’s just about credibly communicating that through a sustainability lens.”
Many businesses, he noted, already have several checklist elements in place, such as internal policies, environmental impact accounting, perhaps even an audit trail or a first sustainability report. The role of technology is to consolidate and harmonise that data so it serves multiple purposes at once.
“With technology, we can harmonise the data so that with the same set of data, you can satisfy multiple outcomes. You can satisfy a sustainability report for your customer, a green finance requirement from the bank, an ISO requirement, or a TR 149 certification,” Benjamin explained.
He illustrated this with how ESGpedia supports each level of the TR 149 journey in practice:
- Localised, accurate carbon accounting. As the first Full Licensee of the Singapore Emission Factors Registry (SEFR), ESGpedia has helped over 800 local companies access more than 300 localised emission factors for Scope 1, 2, and 3, with automated mapping and unit-of-measurement conversion, plus AI tools like OCR that capture data from even bespoke supplier invoices.
- Sustainability reporting and finance. ESGpedia produces tender-ready sustainability reports in as fast as one week when data is in place, and has supported more than 300 companies, many of them first-time SME borrowers, to attain sustainability-linked loans with partner banks.
- Queen Bee supplier enablement programmes. ESGpedia supports supply chain sustainability and green procurement initiatives, where large corporates such as Razer and City Developments Limited (CDL) leverage the digital platform to enable their suppliers to measure their emissions and publish their first Sustainability Reports, directly addressing TR 149’s Supply Network dimension.
- Product-level footprinting. ESGpedia takes companies from life cycle assessments (LCAs) through to third-party verified Environmental Product Declarations (EPDs), which score points under green product labelling schemes such as the BCA Green Mark, addressing TR 149’s Product Life Cycle dimension.
The results are showing up on businesses’ bottom lines: in a recent ESGpedia client study, homegrown firms reported winning up to 15% more tenders after adopting sustainability practices, alongside cost savings from reduced energy use.
5. The SPIN Fans story: From first sustainability report to 66% cost savings
If the framework felt abstract, Darran Ong’s sharing made it concrete. SPIN Fans, a homegrown designer ceiling fan manufacturer, has spent the past three years embedding sustainability into how it thinks, operates, and grows.
“Sustainability is no longer an option for us. It is embedded into our business purpose,” Darran shared. “As a ceiling fan brand, our role is not just to sell products; it is to curate comfort and wellness in a way that is sustainable for people and the planet.”
SPIN Fans’ journey began in 2023, when an exploration of fleet electrification led the company to the DBS ESG Ready Programme and, working with ESGpedia, its first ever sustainability report. The company transitioned its vehicle fleet to EVs in 2024, and has since woven sustainability into product innovation and life cycle assessment.
Like many SMEs, SPIN faced limited manpower and expertise, complex reporting requirements, and data scattered across teams in hard copies. “At the start, it can be very overwhelming because there are so many things to report,” Darran admitted. “ESGpedia helped us structure it in a way that is easy for us to understand, and data is only useful when we can trust it.”
The outcomes speak for themselves: three consecutive years of verified ESG reporting, a target to cut GHG emissions by 70% by 2028 against a 2023 baseline that has already been achieved ahead of schedule, and 66% annual operational cost savings from vehicle electrification, alongside stronger business tender and partnership readiness.
Darran closed with three lessons for fellow SMEs: start before customers demand it, take baby steps because “progress beats perfection”, and embrace AI and digital tools to lift the administrative burden.
“Sustainability is a team sport,” he said. “It cannot sit with just one person or one department.”
6. FAQs: Your TR 149 questions, answered
The Q&A segment drew a wave of practical questions which, as Benjamin observed, focused on how to do it rather than why. Here are the highlights.
Who can certify TR 149, and how long does certification last?
Any accredited verifier can conduct TR 149 verification. The Singapore Environment Council has already stepped forward and is ready to certify companies today, while C3T is in discussions with other established verifiers, including TÜV SÜD, Bureau Veritas, UL Solutions and SGS, to bring them on board at competitive rates. Certification typically lasts one to three years, and Hu Ching encouraged companies to treat renewal as a promotion opportunity: “If you have Bronze today, in two years’ time you should aim to get Silver.”
Benjamin added that digitalisation smooths the verification process itself: “Having the digital data, supporting evidence and calculations all within the same platform typically results in a faster turnaround for verification, as opposed to doing it totally offline.”
How much does TR 149 certification cost?
On verification, Hu Ching offered a useful benchmark: “If you are familiar with the cost of obtaining ISO 14001, it’s typically in the low four digits. We are talking to the verifiers to say: for TR 149, as a national service, peg that cost to ISO 14001 or even lower.” Structuring data well, which is the very aim of the Green 100 platform and digital tools, makes the verifier’s job easier and directly reduces verification cost.
On solutions, Benjamin explained that ESGpedia’s pricing is modular and outcome-focused, whether the goal is a product LCA, a sustainability report or carbon accounting, and that technology’s scalability keeps it affordable even for large corporate groups. Support is also available today: SMEs are eligible for up to 50% funding support for pre-approved solutions like ESGpedia under the Productivity Solutions Grant, and SBF is actively advocating for further government support for companies pursuing TR 149.
How does TR 149 compare with EcoVadis ratings and the upcoming Singapore Sustainability Disclosure Standards?
EcoVadis assesses a broader ESG scope that includes social, human rights, and governance metrics, and it uses proprietary scoring, whereas TR 149 is an open standard with independent third-party validation. And being homegrown matters: “Because TR 149 is endorsed and published by the Singapore Standards Council, and the government has committed to incorporating sustainability considerations in procurement across all categories, I think TR 149 is going to be there when it comes to government procurement,” Hu Ching shared. “The announcement might come one or two years later, but this is going to be the direction.”
As for the Singapore Sustainability Disclosure Standards, currently under public consultation by ACRA and modelled on IFRS S1 and S2, the two are complementary: “The Singapore Sustainability Disclosure Standards are really meant for investors, to allocate capital. TR 149’s use case is really for sustainability-linked loans and for procurement,” Hu Ching explained. “If you’re a large company, you should get both. If you’re a small company that’s not listed, you should aim for TR 149.”
Is TR 149 only for SMEs?
No. It is designed for everybody. As Hu Ching put it: “I hope that one day, every company, large or small, will be able to get the Gold tier.”
