Carbon Footprint Maps by Zip Code

U.C. Berkeley has created an amazing set of resources under the name Cool Climate Network. It's worth exploring their site in general, but one of the most fascinating areas is the interactive carbon footprint map, based on data from their CoolClimate Calculator and the research of Christopher Jones and Daniel Kammen. For those interested in how the maps were created, the abstract of their paper is below. Whether or not you care about how it works, go to the site and just start playing around. It is quite intuitive and very informative. The URL is

Data are from the following paper:
Christopher M. Jones and Daniel M. Kammen, "Spatial Distribution of U.S. Household Carbon Footprints Reveals Suburbanization Undermines Greenhouse Gas Benefits of Urban Population Density." Environ. Sci. Technol., 2013,

Which municipalities and locations within the United States contribute the most to household greenhouse gas emissions, and what is the effect of population density and suburbanization on emissions? Using national household surveys, we developed econometric models of demand for energy, transportation, food, goods, and services that were used to derive average household carbon footprints (HCF) for U.S. zip codes, cities, counties, and metropolitan areas. We find consistently lower HCF in urban core cities (40 tCO2e) and higher carbon footprints in outlying suburbs (50 tCO2e), with a range from 25 to >80 tCO2e in the 50 largest metropolitan areas. Population density exhibits a weak but positive correlation with HCF until a density threshold is met, after which range, mean, and standard deviation of HCF decline. While population density contributes to relatively low HCF in the central cities of large metropolitan areas, the more extensive suburbanization in these regions contributes to an overall net increase in HCF compared to smaller metropolitan areas. Suburbs alone account for 50% of total U.S. HCF. Differences in the size, composition, and location of household carbon footprints suggest the need for tailoring of greenhouse gas mitigation efforts to different populations.

Video of Damming the Rainforest Talk

Weston Media Center was on-hand to video Willie O'Laughlin's June 23rd talk on the Belo Monte Dam and other projects impacting the Amazon Rainforest. We are posting the video here for your convenience, but you can also find it on the Weston Media Center's Vimeo Channel (see links below).
