Private Assets Can’t Hide from SEC’s Proposed Climate Rule

  • The SEC’s proposed climate-disclosure rule may draw a line between private and public general partners (GPs) in the U.S., potentially creating different disclosure requirements for their portfolios.
  • The proposed rule may indirectly bring climate transparency to 11% of global private capital as U.S. GPs may hold non-U.S. private companies in their portfolios.
  • Portfolio companies held by U.S. public GPs were estimated to have a higher average carbon intensity than those held by private GPs. In recent years, however, public GPs have been shifting away from carbon-intensive assets.

Much has been written on the U.S. Securities and Exchange Commission’s proposal requiring U.S.-listed companies to disclose information on climate-related risks. What is less understood is how these proposed rules may affect private markets — in particular, the portfolios of U.S.-listed general partners (GPs), where emissions generally count as Scope 3 Category 15 (financed emissions) in a fund manager’s reports.1 In reality, the rule may represent the camel’s nose under the tent as the SEC indirectly brings climate transparency to private companies — albeit for a limited subset.


Financed emissions reporting: Where’s the data?

The SEC’s proposal would require disclosure of Scope 1 and 2 emissions, and Scope 3 emissions’ categories, if deemed material.2

For companies in the asset management and custody banks Global Industry Classification Standard (GICS®)3 subindustry, which includes U.S.-listed GPs with significant private holdings such as KKR & Co. Inc., The Carlyle Group and Blackstone Inc., financed emissions accounted for 99% of their total emissions footprint (see exhibit below). However, where companies in this subindustry disclosed data, it was partial, accounting for as little as 7% of their total assets under management.4


Sector-estimated average emissions per scope and category

Total value-chain emissions per scope and category were based on MSCI ESG Research’s model that estimates Scope 3 emissions and the average emission intensities per sales of the 2,565 companies in the MSCI USA IMI with a market cap larger than USD 75 million. Data as of June 3, 2022.
Scope 1 emissions are direct emissions while Scope 2 emissions are indirect emissions from the generation of purchased energy. Scope 3 emissions stem from the value chain outside of Scope 1 or 2 emissions. Scope 3 emissions are further divided into 15 categories, of which Category 11 includes emissions from the use of goods and services sold. Category 15 emissions are financed emissions applicable to debt and equity investments.

Public US GPs’ exposure to global private markets

The SEC’s proposed climate disclosure rule may draw a line between private and public GPs in the U.S., imposing a tougher burden on public GPs. If adopted, the proposal would require public U.S.-listed GPs to report their portfolios’ emissions footprint. Using Burgiss data on private holdings, we estimate that 11% of global privately held capital would be affected.5 That’s a small but meaningful share of the world’s estimated USD 5.4 trillion in privately held assets. The greatest regional shares of private capital affected are in the Pacific (14%) while the lowest are in the Middle East and Africa (see exhibit below).

Public US GPs shifting away from carbon-intensive assets

Observers have criticized a shift of carbon-intensive assets to private markets or to buyers with weaker environmental commitments.6 We estimated that U.S.-listed GPs were more exposed to companies that had a higher weighted average carbon intensity than companies held by private U.S. GPs, based on estimates of Scope 1 + Scope 2 carbon intensities.7

U.S.-listed GPs had greater exposure to companies with carbon intensities in the “very high” band (exceeding 525 tons CO2/USD million of sales), largely attributed to energy, materials and utilities companies. In contrast, the distribution of carbon-intensity estimates for private GPs skewed toward the “very low” carbon-intensity band (less than 15 tons CO2/USD million of sales), with companies typically in the information technology and communication services sectors.

The share of investment flow by listed GPs to carbon-intensive companies appears to be decreasing. As of Q4 2021, nearly one-fifth of the listed GPs’ long positions in the 10 most-carbon-intensive subindustries was from investments that originated in the 2008 to 2014 period, compared to less than 10% in the case of private GPs. By the 2015 to 2021 period, however, U.S.-listed GPs had noticeably reduced the investment flow share to this subindustry segment at a faster rate than their private counterparts.8


Average carbon footprint and investment flows for listed and private GPs

Data as of Q4 2021. Carbon-footprint analysis is based on aggregated company holdings valuation of ~USD 4.3 trillion; investment shares are based on a total investment flow of ~USD 3.3 trillion made by U.S. GPs. Carbon-intensity estimates were calculated only for companies within the private-capital universe. Properties, natural-resource investments and infrastructure assets are excluded from these calculations because they generally do not have an emissions intensity estimate available yet.

While the SEC’s current focus is on public companies, MSCI and Burgiss estimate that climate disclosures by listed U.S. GPs may shed a light on 11% of global private capital. Such disclosures may open the door to further climate-disclosure rules affecting privately held companies.

The top 10 sub-industries are: independent power producers and energy traders, construction materials, electric utilities, coal and consumable fuels, multi-utilities, marine, industrial gases, steel, airlines and aluminum.
