Mapping California’s Biggest Polluters
Carbon dioxide, as everyone knows, is invisible. But with a little mapmaking magic, the greenhouse gas comes into sharp view in a rainbow of colors, and shows clearly how and where California contributes to global warming.
California’s cap-and-trade program requires the largest emitters of greenhouse gases to pay to pollute. Each metric ton of carbon dioxide (or other greenhouse gas equivalent) requires an “allowance,” with the total supply (the “cap”) falling each year.
The idea is that the rising carbon prices spur facilities to reduce emissions to save money. Last November, an allowance cost $10.09. In May of this year, the price rose to $14.
These maps show the largest emitters. The bigger the dot, the more CO2 or other greenhouse gas the facility emits. Locations are approximate. Emissions data from the California Air Resource Board are from the most comprehensive list available, published in 2010. The agency breaks down facilities into eight sectors.
The distribution of polluters around the state clearly shows concentrations of refineries along the coasts, oil and gas extraction in Southern California inland areas, and other types of facilities scattered around the state.
These maps are part of a special report on climate change in the Summer print edition of the San Francisco Public Press, in collaboration with Earth Island Journal and Bay Nature magazine. It was made possible by the Fund for Investigative Journalism.

Years of Lobbying Helped Transportation Fuels Industry Win Exemptions From California’s Climate Rules, by reporters Ambika Kandasamy and Barbara Grady.
For four years oil companies, airlines and ground transportation industry groups have petitioned California for exemptions from the state’s cap-and-trade greenhouse gas market, saying consumers would take the hit through higher prices at the pump and in stores. And in court they are still arguing that the state lacks the regulatory authority to compel participation. To a degree, they have succeeded.

California’s Cap-and-Trade Experiment
Exasperated by the lack of international political action, regional efforts are taking aim at limiting greenhouse gas emissions. California’s cap-and-trade market promises major reductions. The San Francisco Public Press examined the program in the summer 2013 print edition. The newspaper is available now at local retailers. The stories will run online over the next few weeks.
