Washington - On April 6, the U.S. Environmental Protection Agency (EPA) proposed strengthened standards designed to reduce cancer risks related to emissions from chemical and polymers plants. The proposal targets the reduction of air toxins, including ethylene oxide, chloroprene, benzene 1,2-butadiene, ethylene dichloride, vinyl chloride and smog-forming VOCs (volatile organic compounds). According to EPA estimates, this would reduce toxic pollution by over 6,000 tons/year and VOCs by over 23,000 tons/year.1

The EPA identified over 200 facilities responsible for generating, storing or emitting these toxins. Its proposed new standards would require companies to monitor and reduce levels of these air pollutants, resulting in an estimated $501 million cumulative capital cost with $190 million per year in total annualized costs.2 Another effect would be to limit air pollution in high risk areas like Cancer Ally in Louisiana, which speaks to the EPA's efforts around environmental justice.

This proposal illustrates the importance of accurately assessing the long-term business risks of negative externalities. While short-term financial results may not be impacted by pollution or GHG emissions, over the long term, companies ultimately pay a price for the problems they cause — through regulation, taxes, lawsuits, reputational damage and more. When these externalities are later priced by governments or through market action, these serve to raise cost and influence corporate and consumer behavior.

How Calvert's Principles reduce exposure to affected plants

As part of our research process and application of the Calvert Principles, we account for toxic emissions via our Pollution and Waste custom indicator. Starting with the list of facilities identified by the EPA, we found 137 facilities that were associated with companies we evaluated for potential investment, which span across different GICS sub-sectors including chemicals, oil & gas, industrials and auto parts.

Our approach limits potential exposure to this proposed change in regulatory standards in the following ways:

  1. Only 40 facilities are associated with eligible issuers, versus 97 facilities associated with ineligible issuers.
  2. We calculated the implied capital costs to be $280 million for companies with principles decisions, of which eligible issuers represent just $80 million of that total, or 29%.
  3. For the implied annual costs to facilities, we calculated the implied cumulative costs for facilities associated with principles decisions to be $109 million per year, of which only $32 million (29%) is associated with eligible decisions.3

In total, Calvert owns 18 issuers with a combined exposure to 34 facilities that would be impacted by the EPA's proposal. Given the clear connection between the proposed standards and pricing this known externality (pollution), we ask that these companies support the strengthened emissions standards proposed by the EPA.


Bottom line: Long-term responsible investors should take note of these changes, as governments have signaled that they are no longer sitting on the sidelines. They are ready to step in and legislate where corporations are unable to self-regulate.

3. Analysis assumes that cumulative EPA cost estimates are shared equally by each facility. This does not account for plant size/capacity. We estimate that larger capacity facilities may be associated with large-cap issuers with principles Ineligible decisions, therefore the costs to the Ineligible category may be understated in our analysis.
