For decades, California has used groundbreaking tools to collect and analyze emissions data from a variety of sources to establish a scientific basis for policy making. As its scope has expanded to include greenhouse gas (GHG) reductions, it has sought out similar tools to use to achieve the goals of legislation such as the Global Warming Solutions Act of 2006 (AB 32).
To support this effort, Lawrence Berkeley National Laboratory developed a... Read More

Researchers estimate that those of us in developed countries spend 90 percent of our time indoors, which means that most of the time we are breathing air polluted by emissions from indoor sources. Providing more outdoor air ventilation can improve indoor air quality; however, energy is needed to heat, cool, humidify or dehumidify, and sometimes filter the ventilation air brought indoors from outdoors. Studies have shown that about 10 percent of... Read More
