Leading the Way in Reducing Emissions

We’re making strides to improve air quality for our communities and for our planet.

Advancing a Cleaner Energy Future
OG&E has lowered emissions while keeping our rates among the lowest in the country. By 2030, we expect to see a 50 percent reduction in carbon dioxide emissions over 2005 levels. We’re also making significant reductions in ozone-forming and regional haze-contributing emissions – all while providing affordable and reliable power to the communities we serve.

Doing Our Part for Tomorrow
We’re committed to environmental stewardship and air quality, and our performance speaks for itself. Today, we are at the forefront of our industry. Sulfur dioxide (SO2) emissions have decreased by approximately 90%, nitrogen oxide (NOx) by approximately 75% and carbon dioxide (CO2) by over 40%, below 2005 levels.

Long Description for Key Emissions for OG&E Owned and Operated Fleet per year (in metric tons) chart 


The line graph chart shows the key emissions generated by OG&E's owned and operated fleet for 2005, 2010, 2015 and 2020. Over 15 years, the chart shows a steady decrease in key emissions for each 5-year period.


Numerical values presented on the chart image:

Key Emissions - OG&E Owned and Operated Fleet per year (in metric tons)
Year Sulfur Dioxide (Metric Tons) Nitrogen Oxides (Metric Tons) Carbon Dioxide (Metric Tons)
2005 45,777 35,690 23,992,764
2010 37,351 28,148 23,125,013
2015 24,706 11,319 18,839,633
2020 3,936 9,404 12,287,672


In 5-year increments, the line graph represents the amount of key emissions per year in metric tons for Sulfur Dioxide, Nitrogen Oxides and Carbon Dioxide. Emissions listed for the time period are represented using lines descending left to right horizontally, with dots indicating the amount of emissions for the year listed.

Taking Strides Towards Lowering Emissions
Electrifying Our Fleet
We’ll replace 50 percent of our light-duty vehicles with electric vehicles by 2025, 100 percent by 2030.
Focusing on Clean
We’ve invested in over 800 MW of wind and solar power while converting 35 percent of our coal-fueled fleet to natural gas.
Smart Choices
By offering smart energy usage programs to our customers, we’re giving them the power to save money and manage their energy use.

Reducing Emissions Through Energy Efficiency

We love helping our customers save energy – wherever they live or work. Our SmartHours program helps customers save money by letting them shift their electricity use to lower cost “off-peak” times. We also give our customers access to their personal electricity usage data, empowering them to make energy efficient choices. Combined, our energy efficiency programs have saved as much energy as 1 million homes use in a year while also delaying the need for new power generation.

Leading Change With Our Electric Fleet

We’re empowered to reduce greenhouse emissions by making smart choices on behalf of our company. Upgrading our light duty vehicle fleet to 50 percent electric vehicles by 2025 and 100% by 2030 allows us to meet our goal of reducing the company’s fleet vehicle emissions by 60 percent by 2030. And we’re also integrating fuel efficient vehicles that use Electric Power Take Off (ePTO) equipment while retiring our medium and heavy-duty trucks wherever possible.

Tracking Our Impact with Advanced Monitoring Systems

Our Continuous Emissions Monitoring Systems (CEMS) measure emissions from our power plants around the clock. These state-of-the-art systems allow us to verify compliance and quantify the emission reductions we invest in on behalf of our communities and are certified by the Environmental Protection Agency.
