An important part of improving our sustainability as a business is developing our processes and procedures to a sustainable standard, so they do not produce negative environmental effects.

As such, Newton has worked hard to achieve several certifications and third-party approvals that indicate the effort the company makes to be a responsible business, including responsible product sourcing and best practice in our daily procedures.

Newton is certified with the international standards ISO 9001, ISO 14001 and ISO 45001, all of which enable transparency about our products and best practices to limit their impact on the environment.

These certificates and approvals are available to view below, alongside our Sustainability Report.
