PROGRAM TITLE: Integrated Assessment of Global Change ACTIVITY STREAM: Assessment SCIENCE ELEMENT:Human Dimensions DEPARTMENT OF ENERGY DESCRIPTION: The objective is to improve the ability of decisionmakers to evaluate the benefits and costs, including non-monetary values, of actions to mitigate or adapt to global climate change. This research granting program, first initiated in 1993, supports the development of integrated (end-to-end) assessment of global climate change. Program priorities were set by an advisory committee made up of the major Federal granting agencies, the DOE Policy Office, and the community of integrated modelers. Program direction is highly coordinated with the other Federal granting agencies. The research program supports two topics: (1) the conduct of integrated analysis itself, which will be phased in through 1996; this research requires a strong interdisciplinary environment so that both natural and social science communities contribute to integrated assessments, and (2) the support of basic research on selected subjects that are common to all integrated assessment models. In 1993, the primary subject is forecasting technology innovation and diffusion. The results of integrated assessments are extremely sensitive to assumptions of how to forecast and structure the model to accommodate future technology changes, a subject highlighted by the Intergovernmental Panel on Climate Change (IPCC), the Energy Modeling Forum, and others. To oversimplify, "top-down" models generally assume that increased energy conservation is linked to significantly increased costs, and "bottom-down" models generally assume that further energy efficiency can be achieved at little or no cost. Another focused subject area in 1993 is the search for a rational way to trade off the impacts of one greenhouse gas with another greenhouse gas so that more efficient policy actions (more freedom to develop cost-effective solutions) can be implemented. The research expands on the concept of the Global Warming Potential by including the economic implications of a changing damage function and indirect economic impacts, such as CO2 fertilization effects. STAKEHOLDERS: The primary beneficiaries of the research are the policy offices in DOE, the Environmental Protection Agency, the Executive Office of the President, the Congress, private sector decisionmakers, and community of integrated assessment modelers. The program contributes to the IPCC, the International Institute for Applied Systems Analysis, the Human Dimensions of Global Change Programme of the International Social Science Council, the Energy Modeling Forum, and coordinates with the Electric Power Research Institute. The major program direction complements programs of the other Federal agencies and is coordinated with the modeling and process task groups. SHORT-TERM POLICY PAYOFFS: The payoffs will appear as better integrated models, suited to evaluate the kinds of policy questions asked of them, and as credible as possible both because of their economics sophistication and their connection to the natural and social sciences. These models will directly support policy formulation by estimating the benefits (including non-market valuation) and costs of a broad range of policy alternatives, such as greenhouse gas emission strategies, the value of shifting emissions to a later time period (for instance, carbon sequestration), the impact of mitigation and adaptation research as a policy alternative, and adaptation strategies. The models may also be used to better highlight high priority research areas for the natural and social sciences. PROGRAM CONTACT:John C. Houghton, DOE, ER-74, Washington, DC 20585, 301-903-8288
