Part 2: A Review of Policies and Programs Addressing UHI Across the US
To learn more about the impacts of climate change on our growing cities, I began to research some of the challenges that urban areas are experiencing as they grow. In addition to housing, offices, and shops for consumer goods and services, roads and other infrastructure are needed to support these communities. This brings more heat, and more consumption of energy, goods, and services in a way that is not sustainable. Last week, I took a look at urban trees as a means of reducing the urban heat island effect (UHI) within cities. Here, I’ll be exploring the question: what policies or programs are in place across the United States to reduce UHI in cities using trees?
The American Council for an Energy-Efficient Economy (ACEEE) created a list of cities in the United States with ordinances that address urban heat island and enhance cities’ energy efficiency, which is an integral part of reducing UHI. I reviewed the 50 cities below, looking at their programs and policies to see which were designed specifically to use trees to mitigate UHI.
