Tucson, Arizona

==== Water harvesting ====
The city of Tucson, Arizona, in an attempt to combat climate change, is providing financial incentives for residents to harvest their rainwater. Tucson's water supply, like many Western cities, is drawn from two main sources: surface water that is pumped more than 300 miles from the Colorado River and groundwater.<ref name="Malloy-2020">{{Cite web|last=Malloy|first=Chris|date=November 23, 2020|title=A Desert City Tries to Save Itself With Rain|website=[[Bloomberg News]]|url=https://www.bloomberg.com/news/articles/2020-11-23/harvesting-rainwater-in-a-desert-city}}</ref> The pump expends a significant amount of energy and the Colorado River is diminishing as a result of climate change and overuse.

In 2012, the city began a program that rebates residents as much as $2,000 for the purchase of water harvesting systems. "Water harvesting" refers to rainwater, which is gathered from building surfaces, and stormwater'','' which collects nonpotable storm runoff from streets and earth. The program is financed by a water bill fee of 10 cents per 748 gallons of city water used. In the first few years, the rebate program was not conserving water as efficiently as they anticipated. But in fiscal year 2018 to 2019, the rebate program saved 52.1 million gallons of water.<ref name="Malloy-2020" /> That is enough water to meet the annual usage of 160 households.<ref name="Malloy-2020" /> The city has been trying to grow the approximately 250 people who obtain active rebates each year by introducing a loan program to bring rebates within reach of lower-income residents.

The city government has an ambitious goal to be carbon neutral by 2030 and is integrating changes that will help change local resident's conventional thinking and practices. On May 1, 2020, Tucson began charging residents and businesses within city limits a monthly Green Stormwater Infrastructure fee (13 cents per 748 gallons of city water used), which is projected to raise some $3&nbsp;million a year for public stormwater capture installations and other projects.<ref name="Malloy-2020" /> But this comes at a time when unemployment is rising and the number of low income residents facing unaffordable bills between 2010 and 2018 doubled to 46% as the average bill increased by 119% in Tucson.<ref>{{Cite news|last=Lakhani|first=Nina|date=June 23, 2020|title=Revealed: millions of Americans can't afford water as bills rise 80% in a decade|language=en-GB|work=The Guardian|url=https://www.theguardian.com/us-news/2020/jun/23/millions-of-americans-cant-afford-water-bills-rise|access-date=December 1, 2020|issn=0261-3077}}</ref> Additionally, as part of the citywide climate resiliency effort, Mayor Regina Romero recently announced the planting of a million trees over the next decade.<ref>{{Cite web|last=Sayers|first=Justin|title=For Mayor Romero, 1 million planted trees in city admittedly a 'big effort'|url=https://tucson.com/news/local/for-mayor-romero-1-million-planted-trees-in-city-admittedly-a-big-effort/article_81c4c718-ef9c-5b65-aae2-d6bf979f3c1d.html|access-date=December 1, 2020|website=Arizona Daily Star|date=February 15, 2020 |language=en}}</ref>
