Aviation versus Environment? Late public discussion of this issue did not even put a questionmark. The suspected vast effects of air traffic on global environmental problems such as climate change or ozone layer depletion led to an urgent demand for both practical solutions and a political framework for the conduct of airports and airlines. This book contains the expertise of environmental organisations, politicians, airline and airport managers who discussed these issues on the second Hamburg Aviation Conference, held on February 17 - 19, 1999. Taking into account the environmental and economic needs for air traffic, the conference was a stage for a constructive debate between aviation business and environmentalists and showed a broad range of measures in regard of environmental problems linked with aviation.
