城市温室气体清单评价研究

城市消费了大量的能源,是全球人类活动温室气体的最大排放源,在应对气候变化中起到关键作用.城市温室气体清单评价成为重要的基础性工作,对于制定城市减排目标和计划、评估减排措施效果具有重要的意义.然而,城市开放的空间系统结构导致城市温室气体清单核算面临许多困难和挑战.本文对国内外城市温室气体清单方法和案例进行了回顾与展望,研究内容主要集中在比较城市清单和国家清单方法、联系和区别,分析清单编制的不确定性,在此基础上提出可借鉴的经验与启示,以期推动我国城市温室气体清单研究发展.

Progress in Research of Urban Greenhouse Gas Emission Inventory

Urban areas carry main responsibility for consuming massive energy sources and make great contribution to global anthropogenic greenhouse gas emissions.City and local governments are seen to have a key role in climate mitigation.Hence,one of the important work concerns accounting for city greenhouse gas (GHG) emissions,because it plays significant role in setting reduction targets and evaluating success of local measures.However,open system architectures like city face many challenges for greenhouse gas accounting.Based on the review in details the methodology and case study,our study focuses on the difference and interconnection between country and city GHG accounts,and uncertainty of accounts.Further,we propose the valuable experience in order to improve domestic research on city GHG emission inventory.
