Phoenix is grappling with severe urban heat problems. As the city continues to grow, it is expected to experience a rise in temperatures of three to five degrees on average in the coming years. This makes urban heat a significant concern, especially for vulnerable populations. Phoenix’s extensive urban sprawl, combined with a lack of green space, has exacerbated the urban heat island effect, where cities become significantly hotter than surrounding rural areas due to the high concentration of concrete, asphalt, and infrastructure. In 2022, Nick Lodato, the principal of Emerson Elementary School, wanted to mark the school's 100th anniversary in a meaningful way. He decided that planting trees would be the perfect way to celebrate this milestone while also benefiting the community. The tree planting event not only symbolized the school's strong sense of community but also represented an investment in its sustainable future. Prior to the project, Emerson had only 9% tree canopy cover, which was far below what is necessary to address some of the pressing environmental challenges Phoenix faces.
Tree cover has become critical infrastructure for heat mitigation. Trees provide natural shade and help cool the environment by reducing surface temperatures, which in turn lowers energy consumption and promotes better public health. In addition to offering shade, the native, drought-tolerant trees and plants planted at Emerson will also contribute to carbon sequestration, purify the air, and improve mental health by creating more green spaces for relaxation and outdoor activities.
To complete this project, Emerson Elementary partnered with the Arizona Sustainability Alliance (ASA), a local nonprofit. Together, they planted over 100 trees and plants across the school’s campus, with approximately 125 people attending the event. Volunteers included students and their parents, Tau Psi Omega fraternity members, APS employees, neighbors, former Emerson students and teachers. (1-3)

Project objectives
The goals of the Emerson Elementary Tree Planting Project were:
To celebrate the school's anniversary by strengthening the community through tree planting, promoting sustainability for both the environment and the community.
To educate the community on sustainable planting practices and raise awareness about environmental sustainability.
To mitigate the effects of urban heat, air pollution, and lack of green space, while addressing educational gaps around sustainability.
To create cooler spaces for children and improve outdoor environments for future generations.
To plant native drought resistant trees and plants that enhance carbon sequestration and contribute to environmental health. (1-3)
Implementation activities
Emerson Elementary School partnered with the Arizona Sustainability Alliance (AZSA) Tree Planting Program to organize a community-focused tree planting event. The project was funded by raising over $20,000 from eight different organizations and more than 40 individuals. The event successfully engaged around 125 participants, including students, parents, local volunteers, and community members. During the event, over 100 native, drought-resilient plant species, including 58 trees and 58 plants, were planted across the school grounds. The project also provided an opportunity to promote educational awareness about sustainable planting practices, with the expertise of Trees Matter and AZSA guiding the community on how to adopt environmentally friendly methods for tree planting and climate change mitigation.

Climate-focused activities
Climate change adaptation:
- Increase urban vegetation cover to reduce urban heat island effect
Climate change mitigation:
- Increase the availability of green urban space for carbon storage (street tree cover)
- Improve carbon sequestration through selection of more adaptable species

Details on the roles of the organisations involved in the project
The tree planting project at Emerson Elementary was initiated and organized by the school’s principal, Nick Lodato. The event saw active involvement from various community groups, including students and parents from the school, local neighbors, and Tau Psi Omega fraternity members, who all volunteered their time to help plant trees. The Arizona Sustainability Alliance (AZSA) played a key role by partnering with Emerson Elementary to offer expertise and organizational support through their Tree Planting Program. Additionally, Trees Matter, another local NGO, contributed by providing educational guidance during the event. The project also received support from private sector entities such as Arizona Public Services (utility company) and My Central Phoenix Realtor, as well as assistance from Banner University Medical Center Phoenix.
