Sustainable investing doesn’t just benefit from an active approach — it demands one.

That’s according to TrueMark Investments, which in early March launched TrueMark ESG Active Opportunities ETF (ECOZ). The exchange-traded fund aims to provide investors with access to large-cap U.S. companies that meet a set of environmental, social and governance (or ESG) standards, particularly in terms of carbon footprint. It aims to hold about 75 to 125 positions, with names including Google parent Alphabet Inc., Mastercard Inc. and Sysco Corp. in its top 10.

ECOZ takes an active approach, with TrueMark working alongside the fund’s subadviser, Purview Investments, to identify companies that meet the ESG criteria and have attractive investment profiles, says Mike Loukas, the firm’s CEO. He argues that the ESG sector has “intrinsic shades of gray,” with companies that appear ESG-friendly on many criteria failing in another, such as their carbon footprint. Active management can help avoid these pitfalls, he says.
