We are transparent.

Transparency Matters

A range of approaches has evolved around how to measure the ESG performance of a company, which has led to some confusion in the market. How can ESG scores be so different from one another? The answer is that they are trying to measure different things. While market participants often value a diversity of opinions to support their decision-making, there must be transparency to mitigate confusion and enhance understanding.

S&P Global ESG Scores assess impact alongside risk and sentiment. And we are committed to providing the highest level of transparency, so you can make sustainable decisions with conviction.

ESG in Indices

The methodology of the S&P 500 ESG Index employs rules-based selection using an adjusted version of the S&P Global ESG Scores. Companies may be excluded from the index if they have a low ESG score relative to global industry peers, are involved in controversial business activities, perform poorly relative to the UNGC principles, or are involved in controversies as determined by the Media & Stakeholder Analysis. The S&P 500 ESG Index, which is weighted by float-adjusted market cap, targets 75% of the market cap of industry groups, selecting the top ESG performers as measured by the adjusted version of the S&P Global ESG Scores.
