Methodology
To built spatial databases for understanding current materials, water and energy consumption
perspectives
Based on GIS and remote sensing techniques, we will establish a spatial database that can reflect resource inputs, waste outputs, energy and water consumption scenarios, and their spatial distribution;
To establish inventories of environmental policies and technologies
To design an indicator system for evaluating urban energy-saving and emission-reduction
efficiency
– To identify key urban sectors related with urban energy-saving and emission-reduction;
– To assess the GHG emissions of urban activities by analyzing the energy and material flows from different urban sectors by adopting life cycle assessment (LCA); and
– To design an indicator system and guidelines for evaluating urban energy-saving and emission-reduction efficiency.
To conduct dynamic simulation analysis and to explore the optimized approach on promoting urban energy- saving and emission-reduction efficiency at various
temporal and spatial scales– To screen appropriate environmental technologies
and policies for realizing the potential symbiotic opportunities;
– To assess, by scenario simulation, combinations of possible environmental technologies and policies that can potentially contribute to promoting urban energy- saving and emission-reduction efficiency;
– To explore the optimal approach on promoting urban energy-saving and emission-reduction efficiency;
– To propose appropriate strategies for promoting urban energy-saving and emission-reduction efficiency by considering the local conditions.
