Impax Asset Management has converted its Impax Global Sustainable Infrastructure Fund into an exchange-traded fund, launching the strategy as the Impax Global Infrastructure ETF. The move marks Impax’s first entry into the ETF market and reflects growing investor demand for sustainable strategies delivered through more flexible and tax-efficient investment vehicles.

The newly structured fund now trades on the New York Stock Exchange under the ticker BLDX.

From Active Fund to ETF Structure

Originally launched in 2016, the Impax Global Sustainable Infrastructure Fund was designed to invest in companies providing infrastructure critical to the transition toward a more sustainable global economy. The strategy targets long-term capital growth and income by investing in a diversified portfolio of listed companies operating across sustainability-linked infrastructure systems and services.

According to Impax, the conversion does not change the underlying investment strategy. Instead, it repackages the existing approach into an ETF format that aligns more closely with how institutional investors and registered investment advisors are constructing portfolios today.

Investment Focus Remains Unchanged

The ETF continues to focus on sustainability-driven infrastructure themes, including clean energy and electrification, digital infrastructure, water systems, and waste management. These sectors are seen as essential enablers of decarbonisation, resource efficiency, and economic resilience as governments and businesses adapt to climate and sustainability pressures.

Impax emphasised that the portfolio construction, active management approach, and sustainability lens remain consistent with the original fund, ensuring continuity for existing investors while broadening access to new ones.

Responding to Evolving Investor Preferences

Impax cited the rapid growth of the ETF market as a key driver behind the decision. ETF structures offer features such as intraday liquidity and operational simplicity, which have become increasingly important for advisors managing diversified client portfolios.

The firm also highlighted the potential tax efficiencies associated with ETFs, particularly through in-kind creation and redemption mechanisms, which can reduce capital gains distributions compared with traditional mutual fund structures.

Expanding Access to Sustainable Infrastructure Investing

By shifting to an ETF format, Impax aims to make its sustainable infrastructure strategy accessible to a wider range of investors, including those who prefer exchange-traded products for portfolio construction and risk management.

The launch also signals Impax’s broader strategic intent to adapt its product offering in line with market structure trends, while maintaining its long-standing focus on investing in companies positioned to benefit from the global sustainability transition.

Positioning for Long-Term Growth

The conversion of the fund comes as infrastructure investment linked to energy transition, digitalisation, and resource efficiency continues to attract capital globally. For Impax, the ETF format provides a scalable vehicle to capture long-term growth opportunities in these sectors, while preserving the firm’s active management philosophy and sustainability-driven investment approach.

As sustainable infrastructure increasingly becomes a core allocation within ESG and transition-focused portfolios, the move positions Impax to compete more directly within the rapidly expanding global ETF landscape.
