FFIUS is a benchmark index built to be the basis for investable products. These products will be attractive to market participants concerned about carbon risk in their portfolios and/or climate risk in the world. Companies owning fossil fuel reserves have valuations based on development of their reserves. They have the corresponding risk that those assets will be “stranded” and their valuations will drop if reserves cannot all be extracted due to regulation or market forces. FFIUS removes from the S&P 500 those public companies ranked by The Carbon Underground 200 as having the reserves with the greatest carbon emissions potential.
