This is an actively managed ETF that invests in global companies tied to sustainable infrastructure, including clean energy, water treatment, digital connectivity, and low-carbon transportation. It builds its portfolio using the FTSE Global Infrastructure Opportunities Index as its benchmark universe.

It suits long-term growth and income investors who want to consider both the infrastructure theme and ESG factors.

The ETF is managed by Impax Asset Management using an active management approach.

Within the benchmark universe, the fund actively selects global companies classified as sustainable infrastructure, covering clean energy, water treatment, digital connectivity, and low-carbon transportation. It integrates ESG factors into fundamental financial analysis to manage returns relative to risk.

• Active stock selection rather than passive index tracking
• A focus on the sustainable infrastructure theme through ESG integration analysis

Assets under management (AUM) stand at $102.3M, and the total expense ratio is 0.60% per year.

Compared with IGF, GUNR, GNR, and the other funds shown in the table, this ETF differs strategically through its active management and ESG integration, so it is worth considering differences in investment philosophy rather than a simple fee comparison alone.

Given the nature of thematic infrastructure assets, the ETF tends to show volatility depending on the interest rate environment and infrastructure-related policy trends, while over the long term it moves in line with the expansion of global infrastructure investment.

As an active thematic ETF, its asset base is smaller than that of large passive infrastructure ETFs, and its fund flows appear to be influenced by demand for sustainable investing.

Its strength is concentrated exposure to the infrastructure theme through ESG integration and active selection, while its weaknesses are its small size and a relatively high fee burden typical of active management.

IGF, which also appears in the table, is a large passive ETF in the same global infrastructure theme, with lower fees and greater liquidity. GUNR and GNR are related thematic ETFs weighted more toward natural resources than infrastructure. Comparing other options as well can widen your choices by region and strategy scope: NFRA and GII in the same global infrastructure category, PAVE and IFRA focused on US infrastructure, and TOLZ specialized in listed infrastructure.

Here are the points to review before investing in BLDX. Because it is an actively managed ETF specialized in the sustainable infrastructure theme, you should check the nature of its strategy, its cost level, and the fund size together, and it is also wise to understand in advance how it differs from large passive infrastructure ETFs.

As a small active thematic ETF, its liquidity tends to be lower than that of large passive infrastructure ETFs, and you should also consider that performance swings in the infrastructure and ESG themes may widen with changes in the policy and interest rate environment.

It suits investors who want exposure to the sustainable infrastructure theme through ESG integration and active selection, and if you prioritize cost and liquidity, it is worth comparing it with large passive ETFs such as IGF as well.
