By far the largest source of sulfur emissions is from burning coal to generate electricity. An approximate distribution of sources that generate SO2 is presented in Figure 18.1. The declining trend in SO2 emissions, which is largely as a result of efforts to control SO2 as a source of acid rain, is plotted in Figure 18.2. Note in particular the sharp decline that occurred in 1995, which was a direct result of implementing the Phase I acid rain controls to comply with Title IV of the Clean Air Act amendments.
