Greenhouse Gas Emitters

Maybe you saw the article in yesterday's New York Times about the clickable map identifying greenhouse gas emitters in the US? I looked up the map, and it's even better than the article made it sound. The map is searchable by state, and you can click in for more detail. The site also has preset graphs and charts allowing you to look at contributors by sector, and geography. Here's a screenshot of a bar chart showing Greenhouse Gas emitters by sector.

Note the line of caution at the bottom. But the EPA includes a link to the page explaining the different data sources. The data are self-reported emissions data from large facilities, and the EPA is admirably clear about what the data source is.
