Perhaps the biggest initiative thus far has been the installation of solar panels which meet the electrical needs of the 25 vets, nurses and support staff at its Kirriemuir branch.
In recent months, the group has also invested in a water purifier and oxygen generation system, installed composting bins made from recycled pallets and changed food packaging to eco-friendly and recyclable materials.
Compostable paper towels are now being used across the practices and, through a partnership with PetsApp, appointment reminders, invoices and receipts are sent electronically.
Anything that does have to be printed is printed on FSC certified paper.
Eco-friendly cleaning supplies and sustainable office products are also being sourced from local suppliers.
Other initiatives include avoiding single-use plastic wherever possible, using water butts to collect rainwater for watering plants and washing vans, and planting wildflowers to encourage wildlife.
The group has also installed energy-efficient LED lighting, along with a system to prompt people to turn off lights, and is currently switching signage lighting to LEDs.
Katrin Lewis said: “As we celebrate our 75th anniversary this year, we’ve clearly always been committed to providing the best care for our clients, but it’s vital that this also extends to the impact we have on the planet.
"We’ve therefore embarked on green mission to ensure our practices are as sustainable as possible.
“We’ve also taken inspiration and advice from practices within XLVets, the community of independently-owned veterinary practices that work collaboratively for the greater good of the industry.
"This has helped us to share best practice when it comes to sustainability and make further improvements to our procedures.
“We now have colleagues from all four of our practices in the green team and we’re continually looking at new ways of improving our green credentials.
"Even simple things like using spare Loxicom syringes for lab work, and washing lines instead of relying on tumble drying, as well as redesigning our recycling plan, are making a noticeable and positive difference.
“Since the start of the year, we’ve significantly reduced our carbon footprint and we’re now looking at a number of other exciting initiatives that we’ll be ready to unveil in the coming months.”
