The DEQ North Carolina Community Mapping System is an online, interactive mapping platform that brings together environmental, health, demographic, and infrastructure data to help communities understand local conditions and support environmental justice and planning efforts. Through a web map interface, users can explore layers related to air and water quality, regulated facilities, climate and flooding risks, sensitive receptors (like schools), and community characteristics, allowing residents, advocates, and decision?makers to identify overburdened areas, visualize cumulative impacts, and inform permitting, enforcement, and investment decisions.
EPA’s Community Multiscale Air Quality (CMAQ) modeling system is an open-source, regional air quality model used to simulate how pollutants such as ozone, PM2.5, and air toxics form and move in the atmosphere. It combines detailed atmospheric chemistry, emissions, and meteorology to estimate pollutant concentrations and deposition over time and space. The CMAQ website provides the model code, documentation, tutorials, input datasets, and example applications, supporting researchers and agencies in evaluating air quality policies, health and ecosystem impacts, and interactions between air quality and climate.
Climate TRACE is a global emissions tracking initiative and online platform that uses satellite observations, remote sensing, and other independent data—combined with AI and machine learning—to estimate greenhouse gas emissions from specific countries, sectors, and large facilities in near real time. It provides publicly accessible maps, dashboards, and downloadable data that let users see where emissions are coming from, how they change over time, and how reported inventories compare to independent estimates, supporting greater transparency and accountability in climate action.
NOAA’s HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory) website provides access to a powerful atmospheric transport and dispersion model used to simulate how airborne pollutants, smoke, dust, volcanic ash, and other particles move and spread in the atmosphere. The site offers model documentation, tutorial materials, downloadable desktop software, and online web-based tools that let users calculate air parcel trajectories, dispersion, and deposition patterns based on meteorological data. It is widely used for air quality studies, emergency response, and research on long-range transport of contaminants.
Website providing information on state, Tribal, and federal implementation plans. Information included on approved state regulations, source specific requirements, and nonregulatory provisions.
Report providing evidence-based guidance to inform local actions to reduce air pollution and its impacts on health. Includes interventions to address mobile sources, buildings, industrial sources, agriculture, and individual behavior.
This is a report that provides information on funding and financing approaches that are potentially applicable at state and city levels. It highlights opportunities to leverage public and private financial resources. The report was developed for EU cities, but many of the examples and cases are applicable to U.S. cities.
Case study demonstrating methods for evaluating the emissions, transportation, and health impacts of infill development (building on vacant, underutilized, or bypassed land within already developed, existing urban or suburban areas).
This is the text of the Linn County Iowa air quality ordinances. It provides extensive language on control of air pollution sources through rules and permits.
ProPublica’s Toxmap is an interactive map that visualizes estimated cancer risk from industrial air pollution across the United States. Built from EPA emissions and modeling data, it shows how toxic chemicals from thousands of facilities spread into surrounding neighborhoods, highlighting hotspots where cumulative industrial air pollution may raise cancer risk to levels the government considers unacceptable. The site lets users zoom to specific communities, see which facilities are driving risk, and explore patterns of environmental injustice in overburdened areas.
