Using the Technology Clearinghouse
Contact
The Technology Clearinghouse is one of multiple tools that can assist in identifying emission reduction strategies for stationary, mobile, and area sources by providing information on emissions limits, control technologies, and emerging technologies.
Before using this system you may want to consider the following questions:
Which pollutants am I most concerned about?
Pollutants have different impacts on human health and the environment. For instance, Greenhouse Gases, remain in the atmosphere for many years, their effects have a compounded, global impact. Regional pollutants, such as smog, spread out across a large area. Exposure to other pollutants, such as airborne toxics, can change dramatically depending on how far you are from the source. Air monitoring data which is used to determine a region's ambient air quality attainment status, can provide useful information on the pollutants measured in your community (see the Community Air Monitoring page for more information). To view air monitoring data in your area use the following links:
- Community Air Quality Portal (AQ View)
- Air Quality Data Statistics (ADAM)
- Air Quality and Meteorological Information System (AQMIS)
Which sources do these pollutants come from?
Pollutants come from a wide range of sources, which are divided into three main emission source categories: stationary sources, area sources, and mobile sources. Emissions Inventories are used to track the amount of pollution that enters the air from every source in California. These inventories summarize the total emissions coming from a source (e.g. facility, vehicle type), but can also provide detailed emissions contribution estimates by unit or process. More information about California's emission inventories can be found using the following links:
Which agency is responsible for controlling pollution? How?
The California Air Resources Board (CARB), United States Environmental Protection Agency (U.S. EPA), and 35 local air districts rely upon a combination of regulatory, permitting, certification, monitoring, and enforcement programs to reduce emissions in California. For more information about government roles and responsibilities use the following links:
