I would refer the committee to the national inventory for the absolute figures because I do not have them in front of me today.
But my personal reaction to this is that we've been holding our own. Contrary to the comment I just heard about a 23% increase in greenhouse gas emissions from 1990 to 2004, I would argue that that is possibly the case if you look strictly at nitrous oxide emissions. But if we look at the aggregate of carbon dioxide being sequestered in the soils and methane reductions from livestock, the issue of nitrous oxide may have gone up. But when I do the complete addition across the board, I would state for the record that agriculture is holding its own, if not decreasing.
