Vermont’s iconic autumn foliage through the Green Mountains, can be seen on winding country roads through small towns, charming covered bridges, and antique stores. Natural resources like granite and timber helped support early rural colonist communities. By the 1900’s Vermont was being promoted as a tourism destination, helped by the new legal protections for maple syrup from Vermont trees. Ski resorts popped up quickly, allowing those from out of state to also appreciate the Vermont skyline.
This natural beauty has motivated a historic culture of environmental protection in the state. A few examples of this culture come from the 20th century, when Vermont took action by banning billboards and passing its own Clean Air Act that also included a tax on low-efficiency vehicles. Recently, their flood resiliency projects that partner with regional planning commissions as well as local housing organizations, has been highlighting their work to restore floodplanes, remove dams, and broadly improve the reliability of the public water system.
Looking forward, Vermont has set the ambitious goal of achieving 100% renewable electricity across large and small utilities by 2035. Aging residential infrastructure, lead contamination, and weather events are all major threats to Vermont and young people especially. In the profile below, you’ll find a set of key children’s environmental health indicators that illuminate Vermont’s environmental risks, children’s exposures, and emerging trends in child health and development.

Nationwide: 3.9%
Children’s environmental health indicators (CEHIs) are measures that can be used to assess the magnitude or extent of environmental hazards, environmental exposures, or children’s health outcomes.
Each headline indicator should be a clear, understandable indicator of children’s environmental health, with broad relevance for a range of audiences at the state level – with relevance to the national level.
The indicators as a package should provide a representative picture of children’s health and relation to the environment.
Each indicator should be calculated using an agreed-upon (and published) method and accessible and verifiable data.
Each indicator should be calculated regularly (at least biennially), with a short lag between the end of the period and publication of the data.
The available data needed for the indicator must be sufficiently robust, reliable and valid.
Indicators must be comparable across all or very nearly all 50 U.S. states.

In this profile, counties with “unhealthy” levels of air pollution are those receiving a grade of F for ozone and/or short-term particle pollution (PM2.5), and/or a grade of “Fail” for year-round particle pollution (PM2.5) in the American Lung Association’s 2024 State of the Air report. According to the report, 0% of Vermont children under age 18 live in counties that received a failing grade for at least one pollutant. This only considers the 3 counties where air quality data is monitored, collected, and sufficient (out of 14). Across the US, 39.88% of children under the age of 18 live in counties with unhealthy levels of at least one measure of air pollution. Nationwide, air quality data is monitored, collected, and sufficient in 885 counties (out of 3,243 total).

Children are more vulnerable to the hazards driven by warming temperatures, such as heatwaves, droughts, flooding, and many other cascading effects. Climate change causes an increase in the frequency and severity of temperature anomalies, extreme weather, and natural disasters globally.
EPA’s Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals
that may threaten human health and the environment. Industrial facilities across the
U.S. are required to annually report the amount of each chemical disposed of or
released into the environment, both on- and off-site. Many of these chemicals are
known carcinogens, developmental toxicants, and neurotoxicants that adversely impact
children’s health, such as arsenic, lead, and mercury.
A wealth of research links exposure to poor outdoor air quality, including high concentrations of ground-level ozone, with the exacerbation of children’s respiratory illnesses, including asthma. Several studies link it with the onset of childhood asthma.

Although cancer in children is rare, the rate of pediatric cancer has been increasing since the 1970s. It is the leading disease-related cause of death past infancy in U.S. children. Neither genetics nor improved diagnostic techniques can explain the increased rate. According to the 2020 Childhood Cancer Prevention report, no more than 10% of all childhood cancers are derived from heritable genetic risk factors, and hazardous chemicals are a preventable risk factor that contributes to the remaining cases.
In 2023, 29.0% of Vermont children under age 6 were tested for blood lead levels (BLLs). Of those tested, 4.5% had a BLL ≥ 3.5 μg/dL. Often the most vulnerable children are not tested, and not all who are tested get reported, so this is likely an underestimate of the true scope of children’s elevated blood lead in Vermont. There is no safe level of lead exposure for children. A potent neurotoxicant, lead reduces IQ and impairs other cognitive, behavioral, and developmental functions. In 2021, the CDC lowered the BLL reference value from 5 to 3.5 μg/dL, but much of the available data still categorizes “elevated” BLLs as being 5 ug/dL or higher.

Mounting scientific research links environmental exposures with risk of Attention-Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). Neither genetics nor changing diagnoses or other artifacts fully account for the increased incidences of these conditions. ADHD and ASD data are for children aged 3-17 years in this state.

All children deserve and need a safe and healthy environment to grow and develop. They need clean air to breathe, safe water to drink, nutritious food to eat, and healthy places in which to live, learn, and play. Early exposure to harmful agents can lead to acute and chronic adverse outcomes. Infants and children are especially vulnerable to environmental exposures because they breathe, eat and drink more, in proportion to their body size, than do adults, and because their bodies and brains are still developing.
A blueprint for Protecting Children’s Environmental Health Network set out to identify a set of CEHIs that can be used to provide an understanding of children’s environmental health at the state level. Through this process, CEHN found that robust, valid, and regularly updated state level data–that are comparable across most states–were not readily accessible. States need adequate funding and capacity to collect and make accessible reliable CEHI data in order to set goals and track progress towards improving children’s health.
Children are our future – society has a moral obligation to protect them. Exposure to environmental hazards can and must be prevented. Prevention requires strong environmental regulations, fully funded and supportive public and environmental health programs and a robust workforce.
