Climate Change

Climate change is one of the greatest public health challenges of the 21st century. PHI advocates for healthy and climate-resilient communities that have the right tools to mitigate and adapt to climate change, while promoting strategies to reduce the overall factors which drive climate change in the first place—focusing on the vulnerable communities impacted worst and first. We develop and implement policies that address the root causes of climate change and protect communities from its worst impacts. We design and implement research programs to identify the current and future impacts to communities by tracking rates of asthma, communicable and chronic diseases, and other related health threats. PHI’s adaptation and mitigation strategies emphasize co-benefits for the health, agriculture, transportation, urbanization, and energy sectors—at the local, state, national and global levels.
