AB: A new version of MIT's Emission Projection and Policy Analysis Model (EPPA) has been developed to project global anthropogenic emissions of greenhouse gases (CO_2, CH_4, N2O, SF_6, PFC, HFC), criteria pollutants (NO_x, SO_x, CO, and non-methane VOCs), NH_3, and carbonaceous particulates simultaneously. Emissions are estimated with a 1 x 1 degree resolution based on the underlying activity, such as fossil fuel combustion in various sectors of the economy, industrial production or agricultural activities. For the time period from 1995 to 2100 we have carried out several runs with EPPA to establish a reference scenario and different climate policy scenarios. The emissions of the different 105-year simulations were then used as an input to an improved version of the MIT coupled chemistry-climate model [{\it Prinn et al.}, 1999; {\it Wang et al.}, 1998] that utilizes the computationally efficient urban airshed module [{\it Mayer et al.}, 2000] to predict urban air pollution and its impact on global tropospheric chemistry and thus on climate. This enables us to investigate the effect of climate policies on urban air quality in terms of criteria pollutant emission reductions as well as the impact on ambient concentrations such as ozone. Results of the new EPPA model and coupled chemistry-climate model will be presented. Mayer, M., C. Wang, M. Webster, and R.G.
