The Western Regional Air Partnership (WRAP) will provide emissions data tracking and related technical analyses to assist states, tribes, federal land managers, local air agencies and the US EPA with understanding current and evolving regional air quality issues in the West.

The regional effort on emissions includes work to fully characterize sources important in the West, as well as those sources contributing to Western air quality issues from outside the WRAP region:

• Collection, analysis, and development of western emissions data through the Intermountain West Data Warehouse (IWDW) - Western Air Quality Study (WAQS);;
• Tracking of source processes and activity data, as well as analysis of the associated emissions from fire and biomass burning and the impacts of fire and smoke on ozone and particulate matter;
• Coordination and harmonization with the EPA National Emissions Inventory;
• Development of data for emissions sources from all sectors, both domestic and international for air quality planning in the West;
• Analyses of baseline, trends, and projection data;
• Evaluation of control technologies and strategies; and
• Identifying the effects of climate change on emissions.

To accomplish this, WRAP develops, maintains, and shares databases, supports technical analyses, and provides access to data and results from various information sources to produce consistent, comparable, and complete results for use by individual WRAP member jurisdictions and agencies.
