By Mandy Saucerman on 5/7/19 2:00 PM ![](https://blog.citizensenergygroup.com/hubfs/GettyImages-511245761%20bike%20to%20work.jpg) It’s “Knozone season” in Central Indiana. As we approach the warmer summer months, you can get in the know about how to reduce ground-level ozone and improve air quality.  Knozone is an initiative of the City of Indianapolis Office of Sustainability to make Central Indiana one of the Midwest’s most sustainable, livable regions through education and resources for local residents.   **What is ozone?**  Ozone is a highly reactive gas in the atmosphere that is both natural and manmade. The ozone layer, approximately 6 through 30 miles above the Earth’s surface, protects us from harmful ultraviolet radiation from the sun. However, when ozone develops at ground level, it can have negative impacts on air quality and human health. Ground-level ozone is created primarily from the reaction of manmade air pollutants with heat and sunlight, and is therefore more prevalent in the summer. It is the primary contributor to smog.  **How can you help reduce ground-level ozone?**  Air pollution can affect your health and the environment. Here are a few steps you can take to make a positive difference:  - Walk, bike, carpool or use public transportation - Turn off your vehicle engine when idling for more than 30 seconds - Avoid drive-through lanes - Combine errands into one trip - Wait until after 7 p.m. to refuel your vehicle or use gasoline-powered lawn equipment to cut down on evaporation emissions If you want to be in the know about when ground-level ozone is present in Central Indiana, you can sign up for Knozone Air Quality Action Day alerts at [www.knozone.com](http://www.knozone.com/).  For more tips on improving air quality, visit [https://airnow.gov/](https://airnow.gov/).  ### Current Articles ### Recent Issues - [November 2019 (23)](https://blog.citizensenergygroup.com/engauge/archive/2019/11) - [November 2018 (21)](https://blog.citizensenergygroup.com/engauge/archive/2018/11) - [January 2021 (21)](https://blog.citizensenergygroup.com/engauge/archive/2021/01) - [October 2021 (21)](https://blog.citizensenergygroup.com/engauge/archive/2021/10) - [February 2020 (20)](https://blog.citizensenergygroup.com/engauge/archive/2020/02) - [December 2021 (20)](https://blog.citizensenergygroup.com/engauge/archive/2021/12) - [October 2018 (19)](https://blog.citizensenergygroup.com/engauge/archive/2018/10) - [January 2019 (19)](https://blog.citizensenergygroup.com/engauge/archive/2019/01) - [June 2020 (19)](https://blog.citizensenergygroup.com/engauge/archive/2020/06) - [August 2019 (18)](https://blog.citizensenergygroup.com/engauge/archive/2019/08) - [October 2019 (18)](https://blog.citizensenergygroup.com/engauge/archive/2019/10) - [April 2020 (18)](https://blog.citizensenergygroup.com/engauge/archive/2020/04) - [September 2022 (18)](https://blog.citizensenergygroup.com/engauge/archive/2022/09) - [July 2019 (17)](https://blog.citizensenergygroup.com/engauge/archive/2019/07) - [July 2020 (17)](https://blog.citizensenergygroup.com/engauge/archive/2020/07) - [June 2021 (17)](https://blog.citizensenergygroup.com/engauge/archive/2021/06) - [April 2019 (16)](https://blog.citizensenergygroup.com/engauge/archive/2019/04) - [January 2020 (16)](https://blog.citizensenergygroup.com/engauge/archive/2020/01) - [October 2020 (16)](https://blog.citizensenergygroup.com/engauge/archive/2020/10) - [December 2020 (16)](https://blog.citizensenergygroup.com/engauge/archive/2020/12) - [April 2021 (16)](https://blog.citizensenergygroup.com/engauge/archive/2021/04) - [July 2021 (16)](https://blog.citizensenergygroup.com/engauge/archive/2021/07) - [September 2020 (15)](https://blog.citizensenergygroup.com/engauge/archive/2020/09) - [March 2021 (15)](https://blog.citizensenergygroup.com/engauge/archive/2021/03) - [June 2022 (15)](https://blog.citizensenergygroup.com/engauge/archive/2022/06) - [February 2019 (14)](https://blog.citizensenergygroup.com/engauge/archive/2019/02) - [May 2019 (14)](https://blog.citizensenergygroup.com/engauge/archive/2019/05) - [May 2022 (14)](https://blog.citizensenergygroup.com/engauge/archive/2022/05) - [July 2022 (14)](https://blog.citizensenergygroup.com/engauge/archive/2022/07) - [October 2023 (13)](https://blog.citizensenergygroup.com/engauge/archive/2023/10) - [September 2021 (12)](https://blog.citizensenergygroup.com/engauge/archive/2021/09) - [March 2023 (12)](https://blog.citizensenergygroup.com/engauge/archive/2023/03) - [May 2023 (12)](https://blog.citizensenergygroup.com/engauge/archive/2023/05) - [June 2023 (12)](https://blog.citizensenergygroup.com/engauge/archive/2023/06) - [February 2022 (11)](https://blog.citizensenergygroup.com/engauge/archive/2022/02) - [August 2018 (10)](https://blog.citizensenergygroup.com/engauge/archive/2018/08) - [August 2023 (10)](https://blog.citizensenergygroup.com/engauge/archive/2023/08) - [March 2022 (9)](https://blog.citizensenergygroup.com/engauge/archive/2022/03) [![PDF Archives](https://no-cache.hubspot.com/cta/default/2545024/33b9e93c-8f43-4101-9b48-7e78154731f5.png)](https://cta-redirect.hubspot.com/cta/redirect/2545024/33b9e93c-8f43-4101-9b48-7e78154731f5) **Engauge** is published by Citizens Energy Group, Corporate Affairs Department, under the direction of Shannon Stahley, Director of Corporate and Public Affairs.
