In May 2019 Ethical Consumer viewed the Diomed Developments website for the company's environmental policy or report. No such information could be found. An environmental policy was deemed necessary to report on a company's environmental performance and set targets for reducing its impacts in the future. A strong policy would include two future, quantified environmental targets, demonstration by the company that it had a reasonable understanding of its main environmental impacts, be dated within the two years and have its environmental data independently verified.

Diomed did not meet any of these criteria therefore it received Ethical Consumer's worst rating for Environmental Reporting.

In May 2019 Ethical Consumer searched the Diomed website for the company's policy on the use of the hazardous chemicals parabens, triclosan and phthalates.

Some forms or uses of these chemicals are banned or restricted in the EU or the USA.

Triclosan is an antibacterial and is a suspected endocrine disruptor. Parabens are also endocrine disruptors and have been linked to breast cancer and are used as preservatives. Phthalates, usually DEP or DBP, are used in fragrances and are endocrine disruptors.

A strong policy on toxics would be no use of these chemicals or clear, dated targets for ending their use.

Nothing could be found that specifically mentioned these three chemicals.

Therefore the company received Ethical Consumer's worst rating on toxics.
