Environmental Emissions Trends 1999-2010 Analysis: Alpine Geophysics Report Highlights

Analyzing NOx, SO2, and VOC emissions trends from 1999 to 2010 in the U.S., this report highlights data for different sources including coal-based EGUs, highway vehicles, and industrial processes. The presentation by Paul Loeffelman to the NARUC Subcommittee on Clean Coal and Carbon Sequestration outlines significant changes in emission categories across five regions. Data sources from Alpine Geophysics offer valuable insights into national and regional trends, aiding in environmental policy and decision-making.
