Air Quality

Good air quality reduces rates of lung cancer and asthma complications, and laws to protect healthy indoor air can help improve the air people breathe. While smoking is not the only contributor to air quality, it has been proven to be dangerous to workers, patrons, or anyone exposed to secondhand smoke on a regular basis.

As of October 2016, 17 states had smoke-free air laws that covered workplaces, restaurants, bars, and gambling establishments. As the number of states with comprehensive smoke-free air laws increases, more states would have a key policy in place to support cleaner, healthier air for all.

Climate Adaptation and Mitigation

Climate change has a significant impact on health, worsening chronic diseases like respiratory ailments and affecting mental health. Climate Action Plans (CAPs) outline a set of strategies within specific environmental policy proposals and programmatic initiatives, indicating that state agencies are working together to improve health. By establishing standards for air quality, targets for emissions, or requirements for housing development, CAPs indicate that states are engaging in cross-sector collaborations that benefit health.  

As of 2015, according to an inventory by the Center for Climate and Energy Solutions, 34 states and the District of Columbia had a Climate Action Plan in place. An increase in the number of states adopting CAPs would indicate that states are not only engaging multiple sectors, but also prioritizing their own climate issues and public health.
