Chicago's road salt use plummets as climate change reshapes winters

Climate change has begun to significantly impact winter weather patterns in Chicago, leading to a decline in the city's use of road salt for maintaining road safety during wintertime. For instance, the amount of salt used by the city in the winter of 2023-2024 amounted to only 119,500 tons, a stark reduction compared to 322,000 tons during the winter of 2020-2021. This change reflects the evolving winter conditions that the city experiences, as highlighted by the Commissioner of the Department of Streets and Sanitation, Cole Stallard, who has overseen more than 20 winters in Chicago and acknowledges the variability in weather from year to year. The reduced usage of road salt not only points to changing weather but also raises awareness regarding environmental impacts. Excessive road salt can lead to serious consequences such as contamination of drinking water, detrimental effects on wildlife, soil erosion, and damage to property. The U.S. Environmental Protection Agency has underscored these concerns, prompting local agencies like the Chicago Metropolitan Agency for Planning to advocate for more thoughtful use of salt during winter maintenance efforts. The call for reducing road salt use is embraced across Illinois, as there is a growing understanding among city officials and organizations about the importance of responsible salt management. In addition to reducing traditional salt usage, the City of Chicago has begun exploring alternative options to maintain safe road conditions. One of these alternatives is beet juice, which is being utilized primarily at the beginning and end of the winter season. While beet juice is not a full replacement for salt, it serves as a supplementary material that helps with road safety in milder conditions. Commissioner Stallard emphasizes the value of these alternatives, affirming the need to adapt to winter weather changes while being conscious of environmental responsibilities. Overall, as winter weather continues to shift due to climate change, the City of Chicago is taking active steps to both ensure public safety and limit the negative environmental impact associated with road maintenance. The ongoing adaptations reflect the city's commitment to a balanced approach in navigating the challenges presented by changing winter conditions.
