ESG rating services are essential for investors. However, there is a high variance between them and when I’m saying high variance – it’s more like huge variance.
A good example is America’s most valuable automobile company – Tesla.
MSCI ranks it at the top of the car industry for sustainability, whereas FTSE ranks it as the worst car producer globally.
You read it right.
Tesla is both the best and the worst.
One rating agency claims “It’s the best” while another is putting it in last place. The discrepancy reflects the fact that MSCI judges Tesla to be almost perfect on carbon emissions because of its clean technology, while FTSE, which evaluates factory emissions, regards the firm as a serious offender. In this post we will see what are the characteristics of this challenge and how ESGgo platform can help to address them.
The Difference In ESG Ratings
The divergence in rating across large companies is quite surprising. If we look at Facebook (at Figure #4) we can see that on the Environmental pillar they are ‘the best’ if we choose MSCI however, if we ask Sustainalytics the answer is “they are the worst”.
The same thing is going on with JPMorgan Chase, J&J, Wells Gargo and Pfizer on the Governance pillar.
Data at Variance
There are four factors that give rise to inconsistencies across ESG rating services:
- Data discrepancies – There is a significant variety of the metrics that purport to measure much the same thing. The diversity of measures gives rise to considerable dissimilarity in ratings reflecting firm-specific attributes, differing terminologies, metrics and even the units of measurement.
- Benchmark choice – There are differences in how raters define the benchmark for comparisons. For example, Sustainalytics compares companies to constituents of a broad market index, whereas S&P compares companies to industry peers.
- Data imputation – at the company level, ESG ratings are plagued by missing data. When a company does not reveal metrics, some ESG raters assume the worst and assign a score of zero. Other raters give it a score that reflects peers that do report the data. Don’t ask me why.
- Information overload – reflecting the never-ending expansion in the volume of public information and the lack of consensus on metrics, there is greater scope for raters to disagree about the scores for particular companies.
