Sustainability at Work offers three levels of certification to recognize your business’s positive impact on our environment and our community. Certification will help you share your achievements with staff and customers, and capitalize on your success.

Steps to Certification

  1. Download application - Download an application (see below). Before filling out, save a copy to your computer and open with the most recent version of Adobe Reader. For mobile devices, download the Adobe Reader app.

  2. Email application - Email the application to us at

  3. Verification visit - We’ll contact you within two days of receiving your application to schedule a verification visit. A visit typically takes an hour to complete.

  4. Certification awarded - We will send you certification materials (see below) and include your business on our website and in our marketing communications. Your certification lasts for three years. At the end of that period, your business will need to submit a new checklist and meet the latest program standards for renewal.
