    查看更多>>摘要:This study provides a comprehensive overview of the challenges to achieving carbon neutrality at the county level in China and offers targeted recommendations,laying the groundwork for future specialized research in this area.A total of 283 relevant studies(2004-2023)were analyzed to assess county-level carbon emissions through three phases:bibliometric analysis,frontier analysis,and future prospects.Biblio-metric findings reveal that publication trends were largely influenced by domestic and foreign policies.Keyword cluster discerns ten primary themes,ranging from conceptual frameworks to research methodologies.The frontier analysis of the literature highlights the leading research areas,which include carbon neutrality pathway,driving factors,spatiotemporal variation of carbon emissions,the co-effects of pollutants and carbon reduction,and carbon emissions in China's rural areas.Drawing from the results of bibliometric and frontier analyses,this study elu-cidates the recommendations for achieving carbon neutrality at the county level from three perspectives:effective regional policy guidance,emphasis on ecological conservation,and the deployment of advanced carbon reduction and sequestration technologies.This study enriches the body of knowledge on carbon emissions at the county level and holds significant implications for China's comprehensive push towards achieving its carbon neutrality objectives.

    Challenges and countermeasures for developing countries in addressing loss and damage caused by climate change

    查看更多>>摘要:Loss and damage caused by extreme climate events have attracted increasing attention.The 28th Conference of the Parties to the United Nations Framework Convention on Climate Change(hereinafter referred to as the Convention)has agreed to adopt Loss and Damage Fund agreement,which identified the source of funding and the funds to be entrusted to the World Bank.However,there is still ambiguous that how to allocate the funds could accelerate the effectiveness of meeting the needs for developing countries.Pre-disaster prevention and preparedness is one of the most effective measures to deal with loss and damage,which closely related to adaptation.Previous studies rarely analyzed quan-titatively the financial needs of pre-disaster prevention and preparedness relating to adaptation to reduce loss and damage.Based on the official reports submitted by countries under the Convention,this study analyzes the annual change in the total financial support provided by developed countries to developing countries,the proportion of pre-disaster prevention and preparedness in the adaptation needs of developing countries,and the progress in raising the current annual funding target of 100 billion USD for developed countries,to reveal the financial and technical challenges facing by developing countries on addressing loss and damage.The results show that by 2030,the total adaptation financial needs of developing countries are estimated to be about 3.8 trillion USD,of which pre-disaster prevention matters account for about 9%.Therefore,by 2030,developing countries will need about 342 billion USD in pre-disaster prevention and preparedness finance to withstand loss and damage.In addition,developing countries face a lack of technical methods to quantify information about their needs.Based on the above analysis,this study puts forward countermeasures and suggestions,including strengthening the allocation amount of loss and damage fund on pre-disaster warning,prevention and control actions,and establishing track modalities on the finance provided by developed countries to developing countries based on the principles of the principle of Common but Differentiated Responsibilities and Respective Capabilities(CBDR-RC),to provide favorable guarantee for accelerating the effectiveness of international climate governance.
