The VanEck Environmental Services ETF (EVX) aims to closely mirror the price and yield performance of the MarketVector Global Environmental Services Index (MVEVX), before accounting for its own fees and expenses. This index tracks companies primarily involved in various environmental services, including environmental consulting and modeling, wastewater and drainage management, general waste disposal, environmental remediation and protection, non-industrial air filtration, and technologies for carbon capture, waste-to-energy, and biofuel production, though it excludes certain recycling activities.
