Xun Xiang’s Playbook: What “Low Carbon” Really Means in an ETF

Speaker: Ong Xun Xiang, Head of ETFs at Lion Global Investors, unpacks what “low carbon” actually means inside an index, how the Lion-OCBC Securities Singapore Low Carbon ETF differs from a plain Singapore index ETF, and why it pays to look at performance across several years.

[About the Speaker] Ong Xun Xiang is Head of ETFs at Lion Global Investors, where he is responsible for building and commercialising the firm’s ETF business, including speaking at ETF events to share investment and industry knowledge with the public. He has worked across asset management, private banking and fintech. Before joining Lion Global Investors, he was a Capital Markets Assistant Vice-President at ADDX (formerly iSTOX), a MAS-licensed digital securities platform, and earlier an Assistant Vice-President in BNP Paribas Wealth Management’s Key Client Group, where he helped originate and manage private market investment opportunities for ultra-high-net-worth individuals. He holds a Bachelor of Accountancy from Nanyang Technological University and is a Chartered Financial Analyst (CFA), Chartered Alternative Investment Analyst (CAIA), Chartered Accountant (Singapore) and ASEAN CPA charterholder.

[The Hook] Xun Xiang joked that “low” does not sound like a flattering word in an investment product’s name. His point was that “low” here describes carbon intensity, not returns, and that investors should look at what the index screens for, how it is built, and how it has performed. This is Part 3 of 4 from the seminar “Diversifying for Changing Markets: Financials, Bonds and Singapore’s Green Leaders”, held at the Tiger Brokers office on 27 October 2026.

[The Backdrop: Singapore’s Net Zero Commitment]

  • Singapore accounts for only about 0.1% of global emissions, yet has committed to net zero by 2050, which it describes as a stretch target given limited options to deploy renewable energy at scale.

  • On 10 February 2025, Singapore committed to cut greenhouse gas emissions to between 45 and 50 million tonnes by 2035, down from around 60 million tonnes in 2030.

  • Why it matters to investors: the Economic Development Board’s chairman has said sustainability concerns will shape Singapore’s priorities in attracting investment, meaning companies here are expected to move towards a lower carbon footprint.

[How the Index Is Built]

The ETF tracks the iEdge-OCBC Singapore Low Carbon Select 40 Capped Index. In plain terms, it starts with Singapore companies and removes the ones that score worst on carbon, then weights what remains.

  • Eligible universe: companies domiciled or incorporated in Singapore that pass a set of relaxed liquidity criteria, with carbon intensity data from Sustainalytics.

  • Bottom-performer exclusions: within each sector, a maximum of 10% of companies with the highest carbon intensity (greenhouse gas emissions per unit of revenue) are removed, and companies with fossil fuel involvement are screened out.

  • The final index: the top 40 companies by free-float market capitalisation (REITs and business trusts included), weighted with a tilt towards lower carbon intensity.

Learning point: what changed in March 2025. The index methodology was enhanced as of the close of 21 March 2025, and the ETF has tracked the updated index since.

  • The number of constituents went from 50 to 40, and the single-security weight cap from 7% to 8%.

  • Permitted fossil fuel involvement went from up to 4.9% to 0%. Palm oil exclusions and norms-based screening (excluding sectors such as alcohol, gambling, tobacco, adult entertainment, defence and cannabis) were added.

  • Carbon emissions considered moved from Scope 1 and 2 to Scope 1, 2 and 3. Generally, Scope 1 covers a company’s direct emissions, Scope 2 its purchased energy, and Scope 3 the wider value chain.

  • Weighting moved from plain free-float market cap to a carbon-intensity “Z-score” tilt on top of free-float market cap.

On the slide’s measure of weighted average carbon intensity (WACI), the Low Carbon Select 40 index scored 28.7 as of September 2026, compared with 67.9 for the Straits Times Index and 132.6 for the MSCI Singapore Free Gross Return Index. Lower means a lower carbon intensity.

[How It Differs From a Plain Singapore Index]

Xun Xiang pointed out that Singapore’s main index is heavily weighted to banks. In the sector breakdown, finance is 67% of the Straits Times Index and 58% of the MSCI Singapore index, versus 36% in the Low Carbon Select 40 index. The rest is spread across REITs (16%), industrials (11%), consumer services (9%), telecommunications (9%), consumer non-cyclicals (8%) and technology (6%).

The country-of-listing slide shows another difference: 79.0% of the Low Carbon index is listed in Singapore, with 12.4% listed in the US and 8.6% in Hong Kong, whereas the Straits Times Index is 100% Singapore-listed. In the top holdings, the three local banks ( $UOB(U11.SI)$, $OCBC Bank(O39.SI)$ and $DBS(D05.SI)$, each about 8% to 9%) sit alongside $Singtel(Z74.SI)$, $Sea Ltd(SE)$ and $Trip.com Group Limited(TCOM)$ (each above 7%), SGX, ST Engineering and others. The speaker’s framing: you still get Singapore, plus broader sector and regional diversification.

[Performance: A Multi-Year Look]

The slide compares the ETF with other Singapore-focused ETFs (all total returns, SGD, as of 30 September 2026). The ETF was listed on 28 April 2022.

  • 2023: 5.8% for the Low Carbon ETF, ahead of the SPDR STI ETF (4.2%), Amova Singapore STI ETF (4.3%) and Xtrackers MSCI Singapore UCITS ETF (3.1%). Per SGX data, it was the best-performing Singapore equities ETF that year.

  • 2024: 27.6%, second best among Singapore equities ETFs (the Xtrackers ETF led with 29.9%).

  • 2025: 26.2%, behind the two STI ETFs (27.5% and 28.1%) but ahead of the Xtrackers ETF (22.7%).

  • 2026 YTD: 7.9%, behind the STI ETFs (25.8% and 26.2%) and the Xtrackers ETF (18.1%).

  • Annualised since inception: 13.3%, versus 16.5%, 16.8% and 15.3% for the three comparison ETFs.

Learning point: a strategy that tilts away from the biggest index weights will not behave like the index. Over some periods it can lead, and over others it can trail. That is why looking at several calendar years, rather than a single headline ranking, gives a fuller picture. The slide’s own caveat applies too: past performance is not indicative of the future.

[Income and Key Facts]

  • Tickers: ESG (SGD) and ESU (USD). The ticker itself is a handy reminder of the sustainability theme.

  • Costs: management fee 0.40% p.a.; total expense ratio 0.53% p.a. as of 30 June 2026. The TER is the broader measure of ongoing costs, so it is worth comparing alongside the headline management fee.

  • Dividends: 12-month dividend yield of 5.02% as of 30 September 2026 (the dividend amount or rate is not guaranteed). Distributions are semi-annual, declared in June and December at the manager’s discretion. Xun Xiang noted that special distributions have also been paid in some past years; none is guaranteed.

  • Rebalancing: the index is reviewed and rebalanced semi-annually in March and September by the index provider, Singapore Exchange. Single-stock weights are capped at 8% (market cap below US$200 billion) or 10% (US$200 billion and above).

[Key Takeaways]

  • “Low carbon” is a screening rule, not a return forecast. It describes how companies are selected and weighted.

  • Methodology matters, and it changes. The March 2025 update tightened fossil fuel exclusions and broadened the carbon measure to Scope 1, 2 and 3.

  • Tilting away from the index changes the mix. Less bank weight and some non-Singapore listings mean a different risk and return profile from a plain Singapore index ETF.

  • Judge performance over several periods. The ETF led in 2023, was second in 2024, and trailed the STI ETFs in 2025 and 2026 YTD.

[Call to Action 🎯]

  1. Compare the top 10 holdings of this ETF with a Straits Times Index ETF. Which names are different, and why might a carbon screen have excluded or reduced them?

  2. Look up the management fee and the total expense ratio of two Singapore equity ETFs and note the difference.

  3. Drop a comment: would an environmental screen change how you choose an index ETF, and why?

    我的看法:
    低碳 ETF 值得投资吗?

    1) 什么是低碳 ETF?

    简单说,就是投资股票时,优先选择碳排放强度较低的公司。

    这只 Lion-OCBC Securities Singapore Low Carbon ETF 会筛选公司,并调整持股比例。

    注意:低碳不代表回报高,也不代表风险低。

    2) 它和普通新加坡 ETF 有什么不同?

    普通 STI ETF:主要投资新加坡大型上市公司,银行股占比较高。

    低碳 ETF:减少高碳强度公司的权重,行业和上市地区更分散。

    低碳 ETF 的金融业占36%,STI 指数约67%。所以两者表现可能很不一样。

    3) 收益表现怎么样?

    根据你提供的数据:

    2023年:上涨5.8%。

    2024年:上涨27.6%。

    2025年:上涨26.2%。

    2026年至9月底:上涨7.9%。

    成立以来年化回报:13.3%。

    成立以来年化回报低于文中比较的 STI ETF(约16.5%和16.8%)。

    这说明:低碳投资有时跑赢市场,有时跑输市场。过去赚得多,不代表未来继续赚。

    4) 股息高吗?

    截至2026年9月底,过去12个月股息率约5.02%,每半年派发一次。

    但股息不保证。股价下跌时,即使收到股息,整体投资仍可能亏损。

    管理费每年0.40%,总费用率约0.53%,投资前要把成本算进去。

    我的看法

    如果你想投资新加坡股票,又重视环保,这只 ETF 值得进一步研究。

    但如果你最重视的是长期回报、稳定股息和低成本,就应该同时比较普通 STI ETF。

    新手记住三点:

    1. 不要只看5.02%的股息率。

    2. 比较长期总回报、费用和持股。

    3. 不要因为名字有“低碳”,就认为它更安全。

    我的结论:低碳 ETF 是一种投资选择,不是保证赚钱的方法。

    环境筛选会影响我选择指数ETF,但**不会成为我买入一只ETF的首要理由**。我更关注的是:低碳策略能否在控制风险和投资成本的同时,创造合理的长期回报。

    这次分享中,最值得研究的并不是“低碳”两个字,而是指数筛选规则如何真正改变投资组合。

    例如,传统海峡时报指数中金融板块权重约67%,而低碳精选40指数降至36%。这意味着投资者买入的不只是碳强度更低的企业,还买入了一个行业结构明显不同的组合。

    **这里存在一个容易忽略的问题:低碳ETF跑赢或跑输传统指数,究竟是因为碳筛选有效,还是因为行业权重不同?**

    2026年截至9月底,低碳ETF回报约7.9%,而两只STI ETF超过25%。我认为这不能简单证明低碳投资失败,因为两类ETF的金融股权重差异很大。如果同期银行股表现强劲,低配银行自然可能拖累相对收益。

    同样,2023年低碳ETF领先,也不能全部归功于ESG策略。

    我会特别关注三个方面:

    ① **风险调整后收益**:不仅比较年化回报,还要看波动率、最大回撤以及相对基准的跟踪误差。

    ② **真实减碳效果**:WACI从67.9降至28.7很有吸引力,但碳强度下降不一定代表企业绝对排放量同步减少,更不能直接等同于现实世界的减排成果。

    ③ **费用与方法稳定性**:0.53%的总费用率高于单纯看到的0.40%管理费,而且2025年指数规则发生重大调整,历史业绩需要分阶段分析,不能全部视为现行策略的验证结果。

    我认为低碳ETF可以成为传统指数投资的补充,但投资者需要清楚自己究竟在承担什么风险、支付什么成本。

    **真正有价值的ESG投资,不应该只证明组合“更绿色”,还应该解释清楚:这种绿色筛选改变了哪些持仓、带来了哪些风险,以及长期回报是否值得付出相应成本。**

    所以我的答案是:**环境筛选会影响我的选择,但我不会为了ESG标签而忽略估值、费用和长期投资回报。** 🐯
