BILD targets sustainable infrastructure companies throughout the world. The fund actively invests in pure infrastructure firms that contribute to the objectives of climate change mitigation and adaptation, and/or positive social impact. The portfolio is constructed using a proprietary process designed to identify companies with carbon reduction targets, low or declining carbon emissions, material investments in assets that contribute to systematic decarbonization, investments to increase infrastructure resilience, as well as companies that make commitments to improve affordability of and access to infrastructure. An exclusionary screen is also applied to remove companies involved in coal, weapons, and tobacco industries, or that have serious violations of the UN Global Compact. In addition to these sustainability metrics, the fund uses a research-oriented, bottom-up and top-down approach to identify high quality, global-listed infrastructure companies.
