摘　　要：Cities are increasingly vital in global carbon mitigation efforts,yet few have specifically tailored carbon neutrality pathways.Furthermore,out-of-boundary indirect greenhouse gas(GHG)emissions,aside from those related to electricity and heat imports,are often overlooked in existing pathways,despite their significance in comprehensive carbon mitigation strategies.Addressing this gap,here we introduce an integrated analysis framework focusing on both production and consumption-related GHG emissions.Applied to Wuyishan,a service-oriented city in Southern China,this framework provides a holistic view of a city's carbon neutrality pathway,from a full-scope GHG emission perspective.The findings reveal the equal importance of carbon reduction within and outside the city's boundaries,with out-of-boundary emissions accounting for 42%of Wuyishan's present total GHG emissions.This insight highlights the necessity of including these external factors in GHG accounting and mitigation strategy development.This framework serves as a practical tool for cities,particularly in developing countries,to craft effective carbon neutrality roadmaps that encompass the full spectrum of GHG emissions.
