Abstract: A centralized emission and energy management system is implemented via a server that is accessible to a client organization. In response to a request to recommend best practices for an organizational unit to reduce environmental impact or energy usage, the system selects relevant best practices based on reduction goals and the organizational unit's particular industry. Based on attribute values for the relevant best practices and the organizational unit, the system filters/ranks the relevant best practices to form recommended best practices. The system may transmit a forecast of energy savings, cost impacts, and environmental impacts over an implementation time period for a draft procedure created from a recommended best practice. The system may generate a request for proposal (RFP) including an approved procedure to a vendor. The system may maintain ratings and feedbacks on the approved procedure and the vendor.
