ET Index Research and FFI Will Collaborate to Provide Indexes and Enhanced Analytics for Investors Concerned about Climate Risks

London, UK and New York, USA ET Index Research (ETIR), producers of the ET Carbon Rankings, which publicly score the largest listed companies according to their greenhouse gas emissions, and corresponding ET Low Carbon and ET Fossil Free Low Carbon Index Series, and FFI, creators of The Carbon Underground 200TM, an internationally-recognized ranking of the top 200 global publicly-traded fossil fuel holders, today announced a collaboration that will incorporate FFI’s research into ETIR’s product offerings. ETIR will now utilize The Carbon Underground 200 and data from FFI’s universe of over 600 global, publicly-traded reserve-owning companies as a fossil fuel screen for its index solutions.

ETIR will also incorporate FFI’s reserves-based emissions research into its ET Portfolio Analytics solution, which helps investors understand the carbon risks embedded in their portfolios.

ETIR CEO, Sam Gill, observed: “Incorporating FFI’s reserves-based emissions data into our offerings allows us to provide a more robust set of carbon exposure analysis tools to our clients, and aligns our definition of fossil free with that of the Divest Invest community.”

Christopher Ito, FFI CEO, added: “We’re excited about this partnership and about the synergies between our two firms. Sam and his team have developed a unique approach to customizing low-carbon index strategies and we look forward to exploring other ways we can work together to enhance our clients’ ability to understand and manage their exposure to climate risks.”

These indexes can be used as a benchmark for fund managers who want an objective comparison for their performance. They can also form the basis of investment strategies or products (like Exchange Traded Funds) that diversify investment across the market while reducing exposure to carbon.

The ET Low Carbon Index Series is underpinned by the public and transparent ET Carbon Rankings – in combination, this is designed to reduce carbon exposure for investors and act as an engagement tool to encourage constituent companies to lower emissions.
