As if there wasn't exhaustive enough evidence that "ESG" is nothing but a scam, the Financial Times was out this week with a piece detailing how many companies with good ESG scores pollute just as much as their lower-rated rivals.

Don't say we didn't warn you; we have been writing about the ESG con for years now, which along with other "sustainable" investments continues to see hundreds of billions of dollars in inflows from investors. 

The FT added to our skepticism by revealing this week that Scientific Beta, an index provider and consultancy, found that companies rated highly on ESG metrics - and even just the 'Environmental' variable alone - often pollute just as much as other companies. 

Researchers look at ESG scores from Moody's, MSCI and Refinitiv when performing the analysis. They found that when the 'E' component was singled out, it led to a "substantial deterioration in green performance".

Felix Goltz, research director at Scientific Beta told the Financial Times: "ESG ratings have little to no relation to carbon intensity, even when considering only the environmental pillar of these ratings. It doesn't seem that people have actually looked at [the correlations]. They are surprisingly low."

He added: "The carbon intensity reduction of green [ie low carbon intensity] portfolios can be effectively cancelled out by adding ESG objectives."

"On average, social and governance scores more than completely reversed the carbon reduction objective," he continued. "It can very well be that a high-emitting firm is very good at governance or employee satisfaction. There is no strong relationship between employee satisfaction or any of these things and carbon intensity."

"Even the environmental pillar is pretty unrelated to carbon emissions," he said. 

Vice-president for ESG outreach and research at Moody's, Keeran Beeharee, added: "[There is a] perception that ESG assessments do something that they do not. ESG assessments are an aggregate product, their nature is that they are looking at a range of material factors, so drawing a correlation to one factor is always going to be difficult."
