AB: Reversing global warming is the defining crisis of the 21st century and must be dealt with, in part, by reinventing the built environment. Current land use and planning frameworks are not aligned with scientific models which can aid in the reversal of carbon emissions at the local and regional scale. The disjunction between land use planning and the scientific methodologies for calculating the impacts of climate change beg for a stronger union between climate change science and land use planning. Buildings account for approximately 35 percent of the U.S. carbon emissions while the transportation sector accounts for approximately 27 percent (U.S. Department of Energy, Energy Information Administration, United States Environmental Protection Agency, 2007). To adopt energy efficiency measures and hence reduce carbon dioxide emissions at a site, city, or regional scale, land use planners and climate scientists must integrate their expertise to influence policy with precision and accuracy. Land use planners have influence over the design of the built environment in municipalities and institutions such as colleges and universities. In many ways, college and university campuses are microcosms of the land use patterns established historically; they demonstrate a lack of coordinated land use planning across the entire continent that is extremely dependent on the automobile and fossil fuels. Climate models predict that the average temperature at the Earth's surface could increase from 2.5 to 10.4ºF above 1990 levels by the end of this century (United States Environmental Protection Agency, 2007). Further, it is estimated that the country will have to construct an additional 213 billion square feet of built space by the year 2030 to accommodate the increasing population. Planning and design will dictate the degree to which land use change will exacerbate trends of global warming. It commands an integration of the methodology to calculate carbon emissions with the science which demonstrates the impact of those emissions. This session presents a new approach and methodology for integrating calculating carbon emissions and land use planning to increase the accessibility of carbon dioxide emissions data, transforming our conception of how the built environment can function in a more sustainable way. The emergence of the public and institutional interest in reducing carbon emissions advances the question of how climate science may be applied and translated for a public audience to develop effective, measurable carbon reduction strategies. Building on the growing momentum in the higher education sector in the United States, land use planners are grappling with the integration of carbon reduction and the transformation of the built environment, particularly at college campuses. A critical first step in reducing carbon emissions is to complete a greenhouse gas inventory. In recent years, universities have adopted challenges to become climate neutral through operations, buildings, and transportation. This session will present two case studies at universities of how land use planning integrates scientific data and suggested methodology from the IPCC, the Chicago Climate Exchange, the Kyoto Protocol, and various other climate action registries in order to demonstrate a university's contribution to global warming. By developing a methodology for calculating CO2 emissions, land use planning and climate science can collectively formulate strategies for a more sustainable future.
