The Petal Project criteria are divided into five categories creating an organized approach to reaching your sustainability goals—one petal at a time.
Download the criteria list by category or review the criteria explanation and resources online:
Petal Certified businesses must complete all required criteria and the minimum number of optional criteria for each category.
Petal Project standards were developed by program staff with input from economic development organizations, Iowa DNR pollution prevention professionals, and assistance from the San Francisco Green Business program coordinator. Project criteria are reviewed regularly to incorporate new resources or innovations available to Iowa businesses. The Petal Project staff are working with a variety of pilot businesses to gather input and feedback on the criteria and process.
Most businesses are expected to implement all required measures along with a minimum number of optional measures for each category. We realize that some businesses may have difficulty implementing some of the criteria.
