Healthy Air and Water Colorado, fondly referred to as “HAWC”, is Healthier Colorado’s climate project. HAWC advocates for public policy that focuses exclusively on the growing public health threats posed by climate change. We know that worsening air quality, rising temperatures and threats to water availability and quality – all products of climate change – have profound impacts on human health, particularly for our most vulnerable community members like those with existing health issues and children. While the rest of our Healthier Colorado work focuses on broadly mobilizing grassroots Coloradans, our charge with this project is to engage health care professionals, including frontline health care providers who see and treat the real health issues caused by our changing environment.
