Report containing tools to equip development finance institution project officers and portfolio managers with information to design projects that generate air quality benefits. It includes basic information on air quality and health impacts, and ways to integrate air quality in investment decisions. The goal is to increase the volume and types of financing available for air quality programs.
CalEEMod (California Emissions Estimator Model) is a free, statewide land use emissions calculator used to estimate air pollutant and greenhouse gas emissions from development projects in California. It allows planners, consultants, and agencies to input project characteristics (like land use type, size, construction schedule, and operations) and then uses built?in emission factors and default assumptions to quantify construction and operational emissions (e.g., vehicle trips, energy use, area sources). The tool supports CEQA review, air district permitting, and project comparison by providing standardized, transparent emission estimates for proposed developments.
The Toxics Release Inventory (TRI) Program tracks the industrial management of toxic chemicals. TRI data are reported annually by industrial and federal facilities that meet reporting requirements. EPA makes these data available through multiple online tools, many of which add context to help make the reported data more understandable.
Document providing basic information on methods for reducing dust emissions
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.
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.
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.
Website providing downloads of two databases: a control measures reference library which provides information on control technologies for a variety of source categories, and a menu of control measures which provides information on existing emission reduction measures including efficiency and cost-effectiveness for large point sources and some nonpoint sources.
