Planet Tracker reveals how current EPA rules allow petrochemical companies to continue polluting local environments and communities with their toxic waste

New York City, 20 September 2022: In a new report launched at New York Climate Week, Toxic Fog – Known Unknowns, Planet Tracker has revealed the regulatory weaknesses around toxic releases that are currently hidden from both investors and the public – despite the clear health hazards – which the Environmental Protection Agency (EPA) is not permitted to reveal.

In light of the paper’s findings, Planet Tracker is calling for financial institutions to demand transparency on toxic emissions so they can conduct a thorough risk assessment of their investments.

Toxic Fog follows on from Toxic Footprints, a previous research paper published by Planet Tracker in July, which revealed the prevalence, toxicity and effect on human health of chemical pollutants, and the facilities most accountable for them.

The report highlights ten major failings regarding toxic emissions. These are split into two categories: data that is hidden from view, but which is still allowed under current regulations, and areas where data transparency can be improved.

Failings within the first category include:

  • Companies can classify their chemical compounds as ‘trade secrets’, which allows them to hide these substances’ names and keep them from scrutiny.
  • Acute human1 and environmental toxicity are not included in the calculation of RSEI metrics, which focus instead on chronic toxicity impacts.
  • Because it usually comes from one-off events or accidents, non-production waste is excluded from permitted emission release thresholds.


In the second category, Planet Tracker identifies areas where data can be improved, or further explanation provided, including::

  • Adding geographic information to the end destination for TRI Basic files, which are the quickest and easiest for companies to use and understand.
  • Ensuring that TRI self-reported metrics include when a facility has breached its legal limit of releases.


The Toxic Fog report reminds readers of the five facilities that regularly and notably contribute toxic emissions to their local environments and communities,. Olin Corp is named the U.S.’s most hazardous company, with two facilities in the Gulf area that account for more than 52 percent of total chemical releases.

Berkshire Hathaway’s Deer Park Plant, run by Lubrizol in Texas, released more than 46,000 pounds of production-related chemicals. In addition, American Acryl’s Bayport Plant released between 14,000 and 144,000 pounds a year between 2007 and 2019.

John Willis, Planet Tracker’s Director of Research, comments: “These ten known unknowns create an operating environment that allows businesses to avoid scrutiny of their chemical releases. Financial institutions can put a stop to this fogginess. By fully understanding the toxic footprint of their investments and their effect on both the environment and human health, they can undertake a fully informed and accurate risk/reward assessment for themselves and for their clients. It’s past time for proper due diligence of the petrochemical industry”.

Greenhushing – sophisticated greenwashing?

Recently concerns have been raised that corporates are ‘greenhushing’, when organisations deliberately choose to hide their green or ESG credentials from public view. Is this an indication that civil society or investors have gone too far in their demands for sustainability metrics, leaving management teams cautious about declaring their progress on green or sustainability issues, or the next step in the evolvement of increasingly sophisticated greenwashing?
