*</sup>Kristin Aunan, PhD, is a research fellow at CICERO. Her research interests focus mainly on the local and regional benefits that may be obtained in a more short-term perspective by implementing measures to reduce greenhouse gas emissions, especially with respect to reduced damage to human health and agricultural crops. kristin.aunan@cicero.uio.no
^**Terje Berntsen has a PhD in meteorology. He works as a senior scientist at CICERO and at the Department of Geophysics, University of Oslo. He has been working with chemical transport models for the troposphere, with focus on oxidation capacity of the atmosphere, tropospheric ozone trends, impact of NOx emissions from aircraft, etc. terje.berntsen@geofysikk.uio.no
^***Hans Martin Seip is professor in chemistry at the University of Oslo and has a part-time position as senior scientist at CICERO. He has worked with environmental problems for about 25 years. A major research field has been effects of acid rain in Europe and in China. He has also studied how inclusion of regional and local benefits will affect benefit-cost analyses of measures primarily directed at reducing emissions of greenhouse gasses. h.m.seip@kjemi.uio.no
