Major annual public markets data update

In line with our regularly scheduled annual data update, Emmi has updated emissions and transition risk metrics for public equities and public fixed income universe data. This comes with improved emissions estimates, mixed emission scopes, and a new scope 3 methodology for high intensity sectors. Overall universe coverage has improved.


What are the high level changes?

  • New machine learning models have been developed, improving overall error rates and emissions calculation accuracy across the board.

  • Mixed emissions scopes are now present in the data set. Emmi will use reported emissions where available, and fill missing emissions scopes with calculated estimates where unavailable, creating a more comprehensive data set.

  • Scope 3 emissions for the universe are significantly higher due to a new methodology for substituting systematic scope 3 under reported emissions in material sectors. We replace Machine Learning and low reported data within these industries with an industry intensity based on hand-picked high quality emissions reporting.

  • We have seen an improved universe coverage, with only 0.03% of output data points requiring quality control interventions.
