ET Index Research helps investors create low carbon investment strategies.

We work with active and passive investors to provide quality carbon data across scope 1, 2 & 3 emissions, portfolio climate risk analytics and a unique range of low carbon and fossil free indexes.

Our Engaged Tracking (ET) Indexes enables investors to do three things:

  • 1) Cut their exposure to carbon risk by tracking a low-cost index.
  • 2) Engage with companies to reduce their carbon emissions.
  • 3) Benefit from the outperformance of low-carbon stocks.

    Each index in the ET Low Carbon Index Series has outperformed the market for the last 6 years. Our indexes encourage more money to back low-carbon businesses by enabling investors to reduce risk and diversify assets (or provide a good benchmark to assess their manager’s efforts). We also help cut carbon by praising publicly companies that do well. Every year, we rank the world’s largest companies by their emissions. This public ranking - the ET Carbon Rankings - highlights the best and worst. Our engagement incentivises corporates to reduce their emissions each year.


Our Services



ET Index Research produces a public Carbon Ranking of the world’s largest listed companies. The ET Carbon Rankings score companies according to the full extent of a company’s carbon footprint. That means not just Scope 1 and 2 (direct and indirect electricity emissions) but also Scope 3 (including emissions from the supply chain and end users). Scope 3 emissions typically account for 75% or more of a company’s carbon footprint and risk.

Organisations can buy our comprehensive ET Carbon Dataset, with access to 2,000 companies analysed directly by ET Index Research, as well as modelled data available for all companies in Bloomberg.

Please contact us if you are interested in purchasing the ET Carbon Dataset. Discounts are available for early 2017 data purchase, which will cover 2,400 public companies. Historical datasets from 2011 are also available.




ET Index Research provides portfolio analytics to help investors identify and understand their exposure to carbon and climate-related risks. A full report provides investors with a 360° view on the carbon exposure of the analysed portfolio. The analysis is in line with best practice as advocated by the Task Force on Climate-related Financial Disclosures and the French Energy Transition Law.

Please contact us if you are interested in a free trial of the ET Portfolio Analytics service.




The ET Low Carbon Index Series is the only low-carbon and fossil-free index series based on a fully transparent, public ranking of all index constituents. Different emissions reduction options and custom strategies are available. ET Index Research actively engages with constituent companies to improve disclosure and lower emissions on behalf of clients. Investor clients also use the ET Low Carbon or ET Fossil Free Low Carbon Index Series, as a main or supplementary portfolio benchmark.
