Observation on data availability/gaps

Different methodologies and scales would require internal evaluation, as it is not transparent on how the ESG scoring is derived. The coverage of companies also varies across these platforms. Bloomberg provides a variety of proprietary scores that investors can use to assess company or government disclosure and performance on a wide range of ESG and thematic issues. Bloomberg’s ESG and thematic scores can integrate into company research and portfolio construction.
