<p>Environmental justice (EJ) mapping tools play a crucial role in addressing disparities in environmental hazards and promoting equitable treatment for all communities. Drawing from observations of tools worldwide, with a particular focus on well-documented examples from the United States, this perspective piece aims to provide actionable recommendations to enhance the usability and impact of EJ mapping tools. Based on our collective experience and analysis, we identified key areas for improvement, including general characteristics, tool resources, and indicator selection. Our recommendations aim to increase transparency, user-friendliness, and overall effectiveness of EJ mapping tools. These insights are intended to support stakeholders globally in advancing EJ goals by facilitating the adoption of best practices in EJ mapping tool development and implementation. The accompanying checklist summarizing the recommendations will serve as a valuable resource for tool developers, policymakers, and communities seeking to address environmental disparities and promote equitable decision-making across various geographical contexts. <i>Clinical trial number</i>: Not applicable.</p>
