Grade summary

Linde produces three SIN List substances, but none of them are officially recognised as chemicals of high concern by the EU. The company has a method in place to screen and assess the sustainability of its products but it does not include intrinsic hazards of ingredients in the screening process. Linde does not have a phase-out strategy for hazardous substances. The company follows several voluntary standards of good conduct and has not been involved in any major controversies over the last ten years.

Opportunities for improvement

  1. Since February 2019, Linde and Praxair have been operating jointly under the name Linde PLC. This merger of equals, including the promised restructuring, offers the opportunity to cut out double standards. We advise the market leader in gases to use the strictest legal standard for its overall global production.
  2. Linde should phase out the few SIN List chemicals it still produces to reduce the hazards even more. Some of the uses can be very specific, however, and need long-term substitution. Therefore, it’s all the more important to start right away.
  3. The Fred Butler company was rolled out to implement textile cleaning processes using CO2 instead of the hazardous PERC. The business was eventually discontinued due to low demand at the time, but the intention was good. Linde should use the lessons learned and try again to cooperate with partners to develop safer and healthier products and processes.

Linde violated air quality standards and pipeline safety regulations twice between 2016 and 2018 and had to pay a fine of 136,907 USD. In September 2016, the US EPA fined the Linde Gas North America plant at Romeoville, Illinois for a violation of ambient air quality standards. Two years later, the US Pipeline and Hazardous Materials Safety Administration levied another penalty for violations of pipeline safety regulations at a Linde facility located in Green River, Wyoming.
