On March 15th, 2021, General Secretary Xi Jinping presided over the 9th meeting of the Central Committee of Finance and Economics, stressing that "we should build a clean, low-carbon, safe and efficient energy system, control the total amount of fossil energy, focus on improving the utilization efficiency, implement renewable energy substitution actions, deepen the reform of power system, and build a new power system with new energy as the main body. Electric power is an important basic industry related to peoples lives.

文摘This paper investigates China's coal price volatility spreaders(CPVSs)from the supply side to locate the volatility source since coal price volatility may destabilize many downstream products'prices or even bring uncertainties to macroeconomic output.Especially in the carbon neutrality context,China's coal market is being reconstructed and responding to imbalances between supply and demand;identifying the CPVSs helps alleviate rising market instability and prevent energy-induced system risk.To achieve this objective,we explore causalities among 938 weekly coal prices reported by different coal-producing areas of China from 2006.9.4 to 2021.7.12 using the transfer entropy method.Then,coal price volatility influence is quantified to identify the CPVSs by conjointly using complex network theory and a rank aggregation method.The validity test demonstrates that the proposed hybrid method efficiently identifies the CPVSs as it correlates to many price determinants,e.g.,electricity and coal consumption and generation.The empirical results show that causalities among coal prices changed dramatically in 2016,2018,and 2020,affected by coal decapacity and carbon neutrality policies.Before 2018,coal-producing provinces with strong demand for coal and electricity,e.g.,Jiangxi,Chongqing,and Sichuan,were CPVSs;after 2019,those with comparative advantages in coal supply,e.g.,Gansu and Ningxia,were CPVSs.Overall,the coal market is unstable and sensitive to energy policy and external shocks.Policymakers and market participants are recommended to monitor and manage the CPVSs to improve energy security,avoid policy-induced instability and prevent risks caused by coal price fluctuations.

文摘The technology of carbon dioxide(CO_(2))enhanced hydrocarbon recovery is favored over other Carbon Capture,Utilization,and Sequestration(CCUS)methods for achieving the"double carbon"goal in China due to its ability to sequester CO_(2) geologically while enhancing the recovery rates of oil and gas resources.However,current technologies face significant challenges,such as limited recovery enhancement capacity,as well as high costs and low efficiency in carbon utilization and sequestration.To address these issues,an innovative carbon-negative technology termed Carbon Capture,Circular Utilization,and Sequestration(CCCUS)is proposed.This technology integrates CO_(2)-microbial enhanced hydrocarbon recovery,CO_(2) underground bio-methanation,and CO_(2) sequestration in depleted hydrocarbon reservoirs.Compared to conventional CCUS technologies,CCCUS stands out through both its modes of carbon utilization and the forms in which carbon exists,by cyclically biochemically converting endogenous and exogenous CO_(2) into renewable natural gas(RNG).A preliminary assessment indicates that CCCUS holds significant developmental potential in China,with 661 million tonnes of CO_(2) utilized per cycle and 3.47 billion tonnes ultimately sequestered.However,there is a significant lack of research on the core technology of CCCUS,specifically CO_(2) underground bio-methanation,in China.To bridge this gap and mitigate potential challenges during the development of CCCUS,targeted proposals have been formulated.This paper provides new insights into advancing the development of a circular carbon economy and accelerating the achievement of carbon neutrality in China.

文摘China is the largest emitter of anthropogenic CO_(2) globally,with its cities recognized as significant emission hotspots.Consequently,evaluating anthropogenic CO_(2) emissions and the carbon neutral capability(CNC)of Chinese cities is critical for climate change mitigation.Despite this importance,no studies to date have assessed recent and future city-scale CNCs using the top-down atmospheric inversion approach,revealing substantial knowledge gaps regarding regional CO_(2) budgets.To address these issues,this research focused on Hangzhou,a megacity known for having the highest forest cover among China’s provincial capitals,as study region.Year-round atmospheric CO_(2) concentration measurements were conducted from December 2020 to November 2021 at two sites:one urban and one suburban.These observations,along with their difference,were utilized to derive city-scale posterior anthropogenic CO_(2) emissions and to evaluate recent and future CNCs.Our key findings are as follows:(1)The manufacturing industry,energy industry and oil refineries/transformation industry were identified as the largest contributors to urban-suburban CO_(2) difference,accounting for 36.5%,21.3%,and 16.6%,respectively.Additionally,82.5%,65.2%,81.2%and 86.3%of total anthropogenic CO_(2) enhancements were attributed to emissions within Hangzhou city in winter,spring,summer and autumn,respectively.(2)The posterior annual anthropogenic CO_(2) emission for Hangzhouwas estimated at 4.65(±0.72)×10^(10) kg/a,indicating significant biases among different prior CO_(2) emission inventories.The annual biological CO_(2) sink,derived from multiple products,was estimated at-0.48(±0.16)×10^(10) kg.(3)The calculated CNC for 2021was 10.3%±3.4%,highlighting a substantial gap towards achieving full carbon neutrality.Considering potential increases in ecosystem carbon sinks due to forest age and uncertainties from climate change,it was predicted that at least 65.2%-82.6%of anthropogenic CO_(2) emissions must be reduced to achieve the goal of full carbon neutrality by year of 2060.

文摘Global land monsoon precipitation(GLMP)is highly sensitive to changes in interhemispheric thermal contrast(ITC).Amplified interhemispheric asymmetries of GLMP due to enhanced ITC driven by high-level anthropogenic emissions are expected to simultaneously increase the probability of regional floods and droughts,threatening ecosystems within global terrestrial monsoon regions and the freshwater supply for billions of residents in these areas.In this study,the responses of GLMP to the evolution of ITC toward the carbon neutrality goal are assessed using multimodel outputs from a new model intercomparison project(CovidMIP).The results show that the Northern Hemisphere-Southern Hemisphere(NH-SH)asymmetry of GLMP in boreal summer weakens during the 2040s,as a persistent reduction in well-mixed greenhouse gas(WMGHG)emissions leads to a downward trend in the ITC after 2040.At the same time,the reduction in WMGHG emissions dampens the Eastern Hemisphere-Western Hemisphere(EH-WH)asymmetry of GLMP by inducing La Niña-like cooling and enhancing moisture transport to Inner America.The resulting increases in land monsoon precipitation(LMP)may alleviate drought under the global warming scenario by about 19%-25%and 7%-9%in the WH and SH monsoon regions,respectively.However,a persistent reduction in aerosol emissions in Asia will dominate the increases in LMP in this region until the mid-21st century,and these increases may be approximately 23%-60%of the growth under the global warming scenario.Our results highlight the different rates of response of aerosol and WMGHG concentrations to the carbon neutrality goal,leading to various changes in LMP at global and regional scales.

文摘This study aims to develop and expand a new perspective on ecological value realization(EVR)and provide policy recommendations for marine ecological value realization(MEVR)based on Carbon Trading.Currently,the immaturity of EVR calculation methods and difficulties in determining the price of ecological products pose significant challenges to ecological value trading.By employing mathematical models and logical reasoning,this study proposes a novel frame-work for EVR,illustrated through several diagrams.According to this frame-work,ecological value is not static but fluctuates with factors such as human well-being(HV)or gross domestic product(GDP).Therefore,ecological value should be determined by an exchange market rather than solely relying on hypothetical calculation methods.Consequently,carbon trading cases are crucial in under-standing ecological value.Based on the analysis of blue carbon(BC)trading cases,including the lack of international BC exchanges,challenges in carbon sink projects,and the Free Rider Effect,this paper identifies current issues in MEVR and BC trading in China.To address these challenges,we propose integrating carbon trading databases with evaluations of ecological protection and restora-tion projects,along with BC trading data,to calculate ecological value.Addi-tionally,we recommend increasing the supply of BC products in both national carbon trading markets and voluntary markets,promoting the internationaliza-tion of BC accounting,addressing the Free Rider Effect through government actions and market mechanisms,attracting more foreign investment in BC en-hancement projects,and formulating a BC enhancement plan during marine resource development.
