Goal Update

2009 Baseline: 1.8 MtCO2e per occupant

November 2021 Update: 1.12 MtCO2e per occupant (37% reduction) *goal exceeded*

December 2019 Goal: 1.36 MtCO2e per occupant

All measurements in thousand metric tons of carbon dioxide equivalent per occupant.

Emissions Reduced

162,500 MtCO2e reduced since 2009-2010.

…which is equivalent to…

34,500 cars’ emissions for one year.


There are many efforts that have resulted in such an exceptional improvement in energy efficiency, including but not limited to: good tracking and use of energy data, consistent analysis of energy trends, broad communication of energy-related opportunities and successes, and implementing new technologies that automate many of these efforts on a real-time basis.

District Average Energy Star Rating

OPS’ current district average Energy Star Rating is 55.4.

Energy Star is an energy efficiency rating program created by the United States Environmental Protection Agency (EPA). Based on a building’s utility data and building characteristics, it provides a rating from 1 to 100. The rating reflects how energy efficient a building is compared to similar buildings. Higher scores are better, and a score of 75 or higher makes a K–12 building eligible to apply for a national Energy Star award with the EPA.

Since higher Energy Star ratings reflect greater energy efficiency, they are a good indicator of reduced emissions. See Energy Star page for more information on energy usage reductions.
