The US EPA has released their latest update to their greenhouse gas document, Inventory of US Greenhouse Gas Emissions and Sinks [441 page, 13.6 MB PDF], covering the years 1990 to 2007.
From the executive summary:
In 2007, total U.S. greenhouse gas emissions were 7,150.1 Tg CO2 Eq. Overall, total U.S. emissions have risen by 17 percent from 1990 to 2007. Emissions rose from 2006 to 2007, increasing by 1.4 percent (99.0 Tg CO2 Eq.). The following factors were primary contributors to this increase: (1) cooler winter and warmer summer conditions in 2007 than in 2006 increased the demand for heating fuels and contributed to the increase in the demand for electricity, (2) increased consumption of fossil fuels to generate electricity and (3) a significant decrease (14.2 percent) in hydropower generation used to meet this demand.
(Note that throughout the document the figures are collected at the end of the chapters, with captions acting as placeholders in the body.)
Probably the most useful single item is Figure 2-6 on page 95, a chart showing the carbon flows in the entire US economy.
And yes, there will be a quiz on this material.
