Our over-arching objective is to develop and demonstrate a comprehensive policy assessment framework that is both broad (multipollutant) and tall (from scenario specification to emissions to impacts). Related objectives are: 1) Apply chemical transport and reduced-form air quality models to assess the air quality and health impacts of various technology, policy, land-use, and climate scenarios; 2) Assess alternative policies, technology trajectories, and land-use variations; and 3) Assess statistical, scenario, and model specification uncertainty, determine the degree to which results are sufficiently robust to justify findings and recommendations, and identify key factors that drive uncertainty.


We will develop a common multipollutant policy framework for studying air quality and climate change that integrates expertise in energy policy, life-cycle assessment, and economics with traditional air quality methods. Our focus will be on four main elements: electricity generation; transportation; land use; and climate-dependent emissions, transport, and chemistry. For each focus area, policy scenarios will be developed with spatially- and temporally-explicit life-cycle emissions inventories that will be used as inputs to newly developed reduced-form models (Project 1) for all scenarios, and state-of-the-science chemical transport models (Project 1) for a subset of scenarios deemed most interesting. We will investigate the role of uncertainty in technology, land use, and policy in shaping model results. The scenarios will explicitly consider both changes in energy and fuel consumption as well urban form.

Expected Results:

We will demonstrate a multidisciplinary, comprehensive, and internally consistent approach for scenario development and assessment, combining models for energy use, transportation technology, life-cycle analysis, state-of-the-art and reduced complexity chemical transport models, exposure, and health effects (with new results from Project 5). Model predictions will quantify the current and future health impacts, climate-related impacts, and the resulting social costs for several technological and policy trajectories. We will examine variability by pollutant and region for each scenario. We will also evaluate results in terms of potential differential effects on specific subpopulations, especially disadvantaged groups (“environmental justice”). Findings will identify region-specific win-win opportunities to address air, climate, energy, health, and environmental justice goals simultaneously.
