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
![Page 18: Recycling Technologies and Evaluation...2009/11/11 · Recycling Technologies and Evaluation Geng Yong Professor, Ph.D Institute of Applied Ecology, Chinese Academy of Sciences Geng](https://reader034.vdocuments.us/reader034/viewer/2022050118/5f4e8aa7a8e4e57f69000154/html5/thumbnails/18.jpg)
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.
![Page 19: Recycling Technologies and Evaluation...2009/11/11 · Recycling Technologies and Evaluation Geng Yong Professor, Ph.D Institute of Applied Ecology, Chinese Academy of Sciences Geng](https://reader034.vdocuments.us/reader034/viewer/2022050118/5f4e8aa7a8e4e57f69000154/html5/thumbnails/19.jpg)
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.
