The Clean200 are the largest 200 public companies ranked by green energy revenues. The dataset is developed by multiplying a company’s most recent year-end revenues by its clean revenue estimate, primarily sourced from Corporate Knights Research supplemented by FactSet, Bloomberg BNEF, and FTSE Russell data. In order to be eligible, a company must have USD revenue of at least $1 billion (most recent available fiscal year-end data) and earn more than 10% of total revenues from clean sources, which extends beyond energy efficiency, green energy, and zero emission and hybrid vehicles. We include banks that are financing the low-carbon solutions; real estate companies leading the way on low-carbon buildings; forestry companies protecting carbon sinks; responsible miners of critical materials for the low carbon economy; food and apparel companies with products that are primarily made of raw materials with a significantly lower carbon footprint; and energy-hungry information and communications technology companies that are leading the way on renewable energy.
