What happens if we cannot measure ESG?

 Barrons:  Tesla (electric cars, batteries) was just added to the S&P ESG Index, albeit with a lower ESG score than Phillip Morris, a US Tobacco manufacturer. From Free Beacon:

ESG ratings are supposed to guide investors, and their money, toward ethical enterprises. But Big Tobacco has lapped Tesla in the ESG ratings race more than once: Sustainalytics, a widely used ESG ratings tool, gives Tesla a worse score than Altria, one of the largest tobacco producers in the world. And the London Stock Exchange gives British American Tobacco an ESG score of 94—the third highest of any company on the exchange's top share index—while Tesla earns a middling 65.

Here's why:

How could cigarettes, which kill over eight million people each year, be deemed a more ethical investment than electric cars? It may have something to do with the tobacco industry's embrace of corporate progressivism.

Companies like Altria have gone out of their way to emphasize the diversity of their corporate boards and the breadth of their social justice initiatives, from funding minority businesses to promoting transgender women in sports. But Tesla, whose executives are overwhelmingly white men, has resisted that bandwagon, going so far as to fire its top LGBT diversity officer last year.

If we cannot measure ESG, we cannot align the incentives of those companies that follow ESG with the investors who want to invest in them.
