Index Construction and Leading Holdings

The index tilts the broad global market toward companies with lower carbon intensity, so the top positions reflect large technology and communication names. Apple accounts for about 5.2% of market value, NVIDIA 4.1% and Microsoft 3.9%. Amazon, Alphabet and Taiwan Semiconductor Manufacturing round out the largest holdings.

The portfolio spans a wide set of countries and sectors, with 1,044 positions. Its weighted average carbon intensity of 59.16 tons of CO2 equivalent per million dollars of sales is one of the metrics the index provider reports for the fund.

Business Involvement Screens and Exposure

The fund applies screens for controversial weapons, oil sands and thermal coal mining. Based on the fund's Business involvement data, exposure to controversial weapons and oil sands is recorded at zero. Tobacco involvement stands at about 1.2% of market value, and civilian firearms involvement at about 0.2%.

Business involvement metrics identify only companies that the data provider has researched, so they do not capture every possible activity within the portfolio. Investors reviewing the fund's screens should keep that limitation in mind.

Trading Details, Costs and Risks

The net asset value rose $6.22 in the latest session, a gain of 2.53%. Shares outstanding total about 4.65 million, and the 30-day average Volume is about 5,200 shares, which is light trading for an ETF of this size. The 30-day median bid-ask spread of 0.21% is worth noting when placing orders.

The expense ratio is 0.20%, consisting of a management fee of the same amount. Distributions are paid semi-annually. The fund's low carbon strategy limits the Investment universe, and it may underperform funds without that restriction or investments in sectors that lag the market.

Final Word

The iShares Low Carbon Optimized MSCI ACWI ETF offers a broad global equity holding with an index design that targets lower carbon exposure. Its concentration in large technology names, low fee and semi-annual distributions shape its profile. Investors will weigh the carbon-focused construction against their broader sustainability and allocation goals.
