CO2 Emissions From Idaho Power-Owned Generation

This chart shows Idaho Power’s historic CO2 emissions in millions of tons from Idaho Power-owned generation.

Idaho Power has been, is, and will continue to be a responsible environmental steward. As with all of our decisions, environmental decisions are evaluated and balanced with consideration of the impact of those decisions on cost to customers and our ability to reliably serve our customers.

Learn how Idaho Power compares to the 100 largest U.S. electric producers in terms of total carbon emissions and emissions per megawatt-hours produced.

Please note: Because of our significant hydroelectric generation resources, our emissions decrease in high water years like 2011.

Year Millions of Tons

The data in this chart comes from the July 2015 Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States, based on 2013 generation and emissions (see pages 10-11 of the report). This report is the product of a collaborative effort among Bank of America, Calpine, Entergy, Exelon, Public Service Enterprise Group (PSEG), Ceres, and the Natural Resources Defense Council (NRDC). Please note this report is traditionally produced annually. The next report is planned to be released in the summer of 2016 with data from 2014.
