Green chemistry is a far-ranging effort to reduce the environmental impact of the chemical enterprise. It focuses on developing and using technologies that are cleaner, smarter, less costly and more sustainable than approaches traditionally used in chemistry and chemical engineering. Authorities on green chemistry are gathering in Washington, D.C., June 26-30 for a conference that promises to be a bonanza of news and background for science and environmental journalists. It is the 10th Annual Green Chemistry & Engineering Conference [ www.greenchem2006.org]. Sponsors include the American Chemical Society, the Royal Society of Chemistry, the National Science Foundation, the U. S. Environmental Protection Agency, the ACS Green Chemistry Institute, the ACS Green Chemistry Institute Pharmaceutical Roundtable, and the Mascaro Sustainability Initiative.
