Environmentally Preferable Purchasing
Environmentally preferable purchasing, or EPP, refers to buying products and services with reduced effects on human health and the environment.
To learn more about environmental purchasing, see PPRC's EPP publications.
EPP Rapid Research Service
Many organizations, cities, counties, states and the federal government are in the process of developing internal procedures to incorporate EPP criteria into their purchasing decisions. This research takes staff time. PPRC is pleased to be able to assist with the process by offering the EPP Rapid Research Service.
PPRC will provide up to 10 hours of research into the environmental aspects of a specific purchasing question. See the list below for previous questions and responses.
Additionally, we have subject-specific Rapid Response services available on:
Here are some of the other topics we have researched but did not respond with a full report. If you're interested in learning more about any of these topics, send us an email and we'll gladly provide you with the information that we have.
