Sources of Air Pollution in the Region

The Houston-Galveston region is one of the largest, fastest-growing, and most economically diverse metropolitan areas in the United States. The region’s air quality is influenced by several major sources of pollution, including emissions from:

• Transportation (cars, trucks, freight, port activity, etc.)
• Industry (petrochemical facilities, manufacturing, etc.)
• Energy (buildings, power generation, etc.)
• Construction, materials management, waste, etc.

The plan also includes a regional greenhouse gas (GHG) inventory, which identifies the largest sources of climate pollution and helps prioritize actions that reduce both greenhouse gases and harmful air pollutants.
