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.
