To manage climate risks, investors need reliable climate exposure metrics, but such risks may be difficult to measure, particularly along the supply chain. Using broadly accessible data, we propose an intuitive metric that quantifies the exposure a company has to customers and suppliers. Our metric is related to scope 3 emissions and captures the strength of economic linkages as well as the overall climate exposure of a firm’s customers and suppliers.

Increasingly many allocators are interested in computing their portfolio’s carbon footprint. We show that historical emissions data are useful despite a substantial 1-2 years’ lag typically to when investment portfolios are built.

Man Group recently wrote an op-ed titled “Short-selling does not count as a carbon offset.” Of course we agree it doesn’t. But the headline is quite misleading if taken to mean shorting has no role in the fight to reduce carbon emissions. Shorting does exactly what it’s supposed to do – raise the cost of capital to the emitters, even more so than divestment.
Some investors have incorporated carbon emissions into investment selection as their primary approach to preparing their portfolios for a future regime shift to a lower-carbon economy. However, carbon emissions can be a narrow measure of overall climate risk. To complement this approach, we explore how machine learning techniques may be able create a broad climate hedging portfolio based on stocks’ sensitivity to climate news.

It would be an understatement to say there is confusion in the industry about the use of shorting in an ESG context. When it comes to calculating a portfolio’s ESG score, we have heard arguments ranging from "ignore the shorts” to “net them against longs,” and, my favorite as it’s creatively insane, “pretend the shorts are actually longs.” This note explains why it is critical that shorts be properly accounted for, so that investors can use shorting to reduce carbon exposure, to get to net zero or to achieve other ESG goals.

We discuss how an investment portfolio could dramatically reduce its carbon footprint, potentially even achieving a ‘net zero’ carbon footprint. We discuss the pros and cons of techniques to achieve carbon reduction goals, including security selection, shorting high carbon footprint companies, and trading instruments such as carbon offsets and carbon permits.
