What TNB's ESG Upgrade Actually Teaches Malaysian SMEs

    26 September 2026 · Ecotabi Team

    In June, MSCI upgraded Tenaga Nasional Berhad (TNB) to an "AA" ESG rating. Alongside it, TNB says it has digitalised the collection of nearly 400 ESG indicators across its 90,000 assets in Peninsular Malaysia.

    If you run a business with a fraction of that headcount and none of that infrastructure, the instinct is to file this under "not relevant to me."

    Fair. TNB is a national utility with a Chief Sustainability Officer. Most Malaysian SMEs don't have one.

    But the part worth sitting with isn't the scale. It's what TNB's Chief Sustainability Officer, Ms Leo Pui Yong, said about what makes it work: "ESG data should be treated with the same seriousness as financial reporting."

    That's not a statement about resources. It's a statement about discipline. And discipline is the one part of this that scales down.

    What financial-grade discipline looks like at SME size

    Your finance team doesn't work out revenue once a year when someone asks for it. The same figure is tracked the same way, every month, by someone accountable for it.

    Most ESG tracking at SME level doesn't get that treatment. It gets estimated once, under deadline pressure, by whoever is free that week.

    The gap isn't the number of metrics. TNB tracks nearly 400. You'd start with far fewer: electricity use, water, waste, headcount by category, incidents, supplier practices. SEDG's Basic level, for example, is 35 disclosures, not 400, and you don't have to do all of it in week one.

    The gap is whether your short list gets tracked the same way each period, owned by one person, and reviewed rather than just collected and filed away.

    It isn't only a reporting exercise

    Ms Leo also made a point about mindset that applies just as directly downward. Talking about IFRS requirements, she said: "We don't see IFRS requirements as just a reporting requirement. We see it as a motivation for us to drive efficiencies."

    That reframe is available to a 20-person business exactly as much as to a national utility. Tracking your electricity consumption properly gives you a number for a report, and it can also show you where you're paying for more than you use. We can't promise that it will, since it depends on your operations. But it's a cheaper place to look than most.

    So what do you do with this?

    You don't need TNB's system, budget or team. You need three things:

    1. One number you already pay for. Start with your electricity bill.
    2. One owner. A named person, not "whoever's free."
    3. One monthly review. Put it next to your management accounts, not in a folder.

    If that feels like a lot for a business your size, it's still less than answering a customer's ESG questionnaire from a cold start.
