Our Sustainability Commitments:

No Need for Nitrous Campaign

We have removed nitrous oxide from use across the group as an anaesthetic agent. Linnaeus commits to working with Associates to make sustainable and quality choices for anaesthesia and analgesia provision.

All new acquisitions using nitrous oxide are enrolled in a removal programme with specialist-led support to improve the quality of care for our patients and planet.


Lower flow anaesthesia

The benefits of lower flow anaesthesia for efficiency, increasing airway humidity and reducing patient cooling are understood, but we are increasingly aware of the impact of volatile anaesthetic agents as greenhouse gases.

Within our We Go for Lower Flow campaign, we have made capnographs available to all sites performing general anaesthesia and produced guidelines to help our practices to become more efficient in their use of these drugs.


Investors in the Environment (iiE) partnership

We are the first veterinary group to partner with the Investors in the Environment (iiE) accreditation scheme, with over 27 of our practices currently taking part in the programme. This scheme was created to help businesses reduce their environmental impacts.

Our Central Support office received the Bronze level accreditation in May 2021 and achieved Silver in May 2022.

Mars Sustainability in a Generation Plan

Linnaeus is proud to be a part of the Mars Veterinary Health family and work with them as they lead the way for sustainability.

In 2017, Mars launched their Sustainable in a Generation plan, supporting the Mars Purpose of ‘The world we want tomorrow starts with how we do business today’.

One Health projects

As part of the Linnaeus commitment to the Mars Five Principles and Sustainable in a Generation plan, we support One Health initiatives within our business and charitable activities.

All of our iiE member practices work towards Corporate Social Responsibility (CSR) projects with a One Health theme.

‘Paws to Turn Off’ campaign

We have launched a campaign to encourage our practices to turn off unnecessary lights and air conditioning, with the aim of cutting down our annual electricity consumption by up to 14 per cent.

We’ve sent over 2,000 ‘Paws to Turn Off’ stickers as part of this, which members of the team can place stickers by the switches to encourage and promote energy-saving behaviour.

The stickers are made from mineral and plant-based ingredients. They are also PVC-free and made with a glue-free, water-based adhesive and are vegan-certified.


At Linnaeus our efforts are driven forward by our Environmental Sustainability Lead, Ellie West. Ellie is an RCVS and EBVS® European Specialist in Veterinary Anaesthesia and Analgesia at Davies Veterinary Specialists. The function of our Environmental Sustainability Lead is to catalyse sustainable working practices across all our businesses.

Ellie first started pioneering veterinary sustainability at Davies Veterinary Specialists in 2017 and has since been a massive influence on Linnaeus and the veterinary industry. Ellie received the Individual Sustainability Influencer award in the iiE ceremony in 2020.

We are proud that Ellie works to educate and spread the word about sustainability to the vets of tomorrow by collaborating with veterinary schools on seminars for their undergraduate programmes. In 2020-2021, Ellie spoke to cohorts of veterinary and veterinary nursing students at the Universities of Bristol and Liverpool.

Ellie West has also been named an official Veterinary Woman Role Model, you can read her full profile here.
