Abstract The report gives results of an analysis of national and regional acid deposition precursor emission trends, involving SOx, NOx, and VOCs. While the focus is on emissions during 1980-1985, comparisons are made (for perspective) with emission trends for 1940-1980. Study methods integrated data from the U.S. EPA's national emission trends reports, state and regional activity indicators, and plant level data for electric utilities and copper smelters. For 1980-1985, all three pollutants showed both annual declines and increases. For a longer term, emission trends can be divided into three periods: (1) 1940 to the mid-1970s, when emissions increased in proportion to fuel use and the GNP; (2) the late 1970s to the early 1980s, the emissions control era, when Clean Air Act programs produced a downward trend for all pollutants except NOx as the economy continued growing; and (3) since 1980, when relationships between emissions and the economy, fuel use, and regulations are making it more difficult to predict emissions in future years.
