Abstract

Urban carbon emissions are greatly influenced by land use patterns in urban areas, which are largely decided by the urban planning program. The procedure for planning program adjustment aim for low carbon is urgently needed in the actual planning process. This paper establishes a land use-based method (LU-BM) using land-based emission factor (LB-EF) approach to evaluate and restrain carbon emissions for urban planning. Through the three-step processes of “Establishment of quantitative approach”, “Analysis of the pre-planning program”, and “Adjustment of the pre-planning program”, the total carbon emissions of 2035 planning of the central urban district in Changxing county, China was evaluated, and the land-use composition and carbon emission intensity in different functional zones were adjusted using land-use planning map and control indexes as the adjustment tools. By calculation, the comprehensive adjustments proposed by LU-BM in total cut 39.67 percent CO2 emission equivalents compared with the original planning, the effects were significant. The results indicate that land use planning and management can be a valuable tool to restrain carbon emissions in planning stage.
