Abstract This study explores the use of Public Participation Geographic Information Systems (PPGIS) to support environmental justice (EJ) efforts in Charlotte, NC by incorporating community knowledge and engagement. Through a workshop with representatives from community-based organizations (CBOs), participants learned about PPGIS, NASA remote sensing data, and environmental screening tools. A hands-on web-GIS demonstration allowed them to identify how PGIS might address challenges in their EJ efforts. Using a mixed-methods approach, both surveys and focus group discussions were conducted to explore community perspectives on the strategic implications of incorporating PPGIS into current EJ efforts. Thematic analysis of the focus group data revealed key themes of community engagement and representation, challenges with coordination, the power of GIS and data, political and policy advocacy, and holistic and intersectional approaches. Assessment of the strengths, weaknesses, opportunities, and threats of current efforts showed that coalition building, community involvement, and local knowledge were key strengths, while weaknesses included limited influence over decision makers and difficulty securing funding. The study concludes that PPGIS could play a strategic role in enhancing community mobilization, facilitating collaboration, and advocating for policy change.
