Located in Halifax, Nova Scotia, we create strategies and programs that encourage people to make lasting changes in their daily lives to conserve resources such as water, energy, and waste.  Our mission? Creating change, through choice. We work with people and organizations to understand their resource costs and then create programs that achieve cost savings by understanding, engaging, and guiding the customer to motivate behaviour change.


We work with utilities, businesses, students, homeowners, and everyone in between.
