Thanks, Michelle. You pose excellent and timely questions.
The Arizona city's "Shade Phoenix" initiative (link below) has admirable aims, methods, and successes in a city strongly affected by global warming and its resulting climate change effects.
It funds the commonly recommended green spaces and tree planting and is linked to a widely reported Cool Streets program of coating asphalt pavements with reflective paints. Commercial buildings are encouraged to employ awnings and green roofs. It employs a "Tree Equity Score" to identify areas of need and public participation to design planting plans.
I no longer live in Phoenix, so it would be good to hear from someone there to get their perspective.
