Third party certifications: a list of sustainability related third party certifications was developed through internet searches, scoping literature reviews and key informant interviews. Webpages for each identified certification were reviewed for relevance and inclusion. Where the certification was determined to be applicable to veterinary clinical practice, information was included in the results section.
Clinical supply type considerations: A list of general supply categories was developed from clinical experience of the editorial team. These included:
- Appliances and electronics
- Cleaning products
- Office supplies
- Paper supplies
- Sharps containers
- Tissue products
For each category, both peer reviewed and grey literature were searched to develop a series of general procurement considerations and guidelines. Human hospital sustainability resources such as the Sustainability Roadmap for Hospitals that could be adapted to veterinary clinics were key resources.
