FEP and the environment - The Facts 

It's always frustrating to see misinformation about FEP that can cause unnecessary concern for local communities. Here our Environmental Engineer, Kylie Bishop, fact-checks some of these. 

Environmental Monitoring Programme

Since starting production 36 years ago, Fife Ethylene Plant has undertaken and continuously evolved a comprehensive programme of environmental monitoring – covering emissions to air, as well as noise and vibration. This monitoring has evolved over time in line with emerging regulations, understanding of environmental aspects and feedback from stakeholders.

Submitted in April 2022 to the Scottish Environmental Protection Agency (SEPA), this latest monitoring programme helps us to accurately assess and address any environmental risks, and ensure we comply with our legal obligations and international agreements.

We monitor all 19 emission points as identified by SEPA, as well as undertaking broader site-wide monitoring.Our latest programme is available here.

FEP and Local Air Quality 

FEP operates to strict environmental standards and our teams work hard to ensure our operations are as efficient as possible.

Fife Council and SEPA regularly monitor air quality to ensure it continues to meet stringent environmental standards.

The following links provide fully independent data that consistently show Mossmorran has no impact on local air quality.

It is highly unlikely for FEP to impact local air quality of people in Fife. 

July 2019

Initial air quality monitoring continues to be in line with previous monitoring and shows no cause for concern 

SEPA 2019

No air quality issues in the vicinity of Mossmorran or Braefoot Bay were identified.

SEPA has published over 20 air quality monitoring reports, each showing that FEP has no impact on air quality. Click here to see their reports. 




Fife Council monitors air quality across the region. Their monitoring again shows that Mossmorran has no impact on air quality. Read more here



This document assesses the impact of emissions (air, noise & vibration) from Fife Ethylene Plant on the local community and environment, with the aim of defining an appropriate forward monitoring plan for these emissions. Read more about our Environmental Monitoring Programme here.
