The report measures air and water pollution, diesel exhaust, toxins and other factors to calculate pollution burdens of communities at the ZIP code level. It also evaluates socioeconomic and health factors such as asthma rates, poverty and ethnicity to determine the population’s vulnerability to pollution.
The final ranking is the product of the pollution and population scores, with the highest scores highlighting the most environmentally impaired communities. Those areas are entitled to funding for environmental cleanup or sustainable development through the state’s greenhouse gas cap-and-trade program. (UT San Diego, 6/8/2013)
