AREA OF IMPACT Not Categorized

Carbon-tilted index provider

US Start-up Tour 2014We have designed a market mechanism to link share price to greenhouse gas emissions. Through our partner, the Environmental Investment Organisation, we have become the first and only body in the world to create a set of public Carbon Rankings scoring the world’s largest listed companies. The Rankings are designed to reward lower emissions and encourage greater transparency.

ET Index Ltd has been created to develop and commercialise a series of stock market indexes based on the Rankings. They are designed to shift capital away from the most polluting companies, towards the more efficient companies. Once adopted by a sufficiently large pool of investors, these indexes will offer the ability to shift demand for companies shares, and therefore influence share price, in line with emissions.
