GCLN is passively managed, providing exposure to global equities with business exposure to the clean energy sector. Companies include those involved in generating renewable power (solar, wind, and hydrogen), and energy storage, clean power infrastructure, energy digitalization and bioenergy. Stocks are selected based on their classification within the industry and relevance to the clean energy theme. Selected stocks are then put through exclusionary screens based on their carbon impact, thematic relevance, and any involvement in ESG controversies. Rebalanced quarterly, the index is market-cap weighted and tilted heavily towards those considered to have the greatest impact towards reducing the worlds carbon emissions. Specifically, those classified as the main driver of decarbonization receive majority of the weight, while those with considerable, moderate, and minor impact receive proportionately less. The fund may include traditional energy exposure to oil, gas or other hydrocarbons.
