What We Do

Engaged Tracking Index Strategies

Our work drives the reallocation of investor capital to low-carbon companies. Each year, we publicly rank the world's largest companies on their carbon emissions data, as part of the ET Carbon Rankings. Using this data, we inform investment strategy by helping investors identify, understand and manage carbon and climate-related risks.

We provide investors with corporate carbon emissions data, portfolio carbon analytics - including footprinting and reporting services - and low-carbon and fossil-free low-carbon indexes. These indexes are designed to act as the next generation of index benchmarks or as the basis for investable products.

Aligning investment strategies with the transition to a low-carbon economy does not mean sacrificing performance. Each index within the ET Low Carbon Index Series has outperformed its benchmark over the last 5 years and we expect this trend to continue.

Our Free Portfolio Analytics helps investors align with best practices (e.g. Mark Carney’s Task Force Recommendations) and growing regulatory pressures, through an easy-to-read online dashboard and modular scorecard report.

Premium Analytics modules (e.g. ESG analysis), access to the underlying data and additional consulting are paid-for services.

The only low-carbon and fossil-free low-carbon index series based on a fully transparent, public ranking of all index constituents, via the ET Carbon Rankings.
