  • Energy Storage & Conversion (advanced batteries, power conversion, electric vehicles, hybrid drivetrains, hydrogen, fuel cells for stationary, portable, and transportation applications, etc.); and

In addition, a security must pass the following screens:

  • be listed on the Nasdaq Stock Market, the New York Stock Exchange, NYSE American, or the CBOE Exchange;
  • have a minimum market capitalization of $150 million;
  • have a minimum average daily trading volume of at least 100-thousand shares;

  • may not be placed in a trading halt for two or more consecutive weeks;
  • the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn;
  • and have a demonstrated ability to capture the potential of the clean-energy sector by receiving a majority (50% or more) of its revenue from clean-energy and low-carbon activities, "or," in the case where a constituent has multiple business units and revenue streams, have substantial exposure to the clean-energy and low-carbon sector, according to Clean Edge.

Classifications are determined by Clean Edge, which has been at the forefront of identifying and classifying the clean-energy and clean-tech sectors for nearly 20 years. The firm’s first report, Clean Tech: Profits & Potential, which defined and highlighted the business and economic case for clean tech and clean energy, was published in April 2001 and Clean Edge co-founder Ron Pernick coauthored one of the first business books on the topic, The Clean Tech Revolution, published by HarperCollins in 2007. In addition to the company’s stock indexing work, Clean Edge has also classified and benchmarked the clean-tech activities of cities, states, and utilities.
