Quantifying spatial and temporal divergence of carbon balance and carbon offset in the Yangtze River Delta Urban Agglomeration under the carbon neutrality coal
Carbon offsetting is an effective means to promote the low-carbon transformation of a region and achieve carbon neutrality goals.Based on the calculation of carbon absorption and offset in the Yangtze River Delta urban agglomeration,the temporal and spatial evolution characteristics were analyzed,and the payment area,compensation area and related functional area were identified through the calculation of carbon compensation amount,ecological carrying coefficient and economic contribution coefficient,and a scientific and reasonable spatial compensation scheme was formulated.The results showed that from 2009 to 2019:(1)The carbon emissions in the study area showed a phased increase with significant fluctuations,presenting a pattern of"increase,slow growth,increase."Spatially,the high-value urban areas along the Yangtze River serve as the axis,with weakening trends in the northern and southern regions.(2)Carbon absorption in the study area fluctuates above and below the balance point of 200 million tons,with a slow growth rate,minimal increment,and overall stability.Spatially,it exhibited a distinct"periphery to center"characteristic.(3)Payment and compensation areas lack coordination in terms of the number of urban areas and compensation amounts,leading to significant pressure on compensation amounts.Therefore,it is crucial to conduct comprehensive planning,strengthen top-level design,control energy consumption,diversify compensation methods,and broaden compensation channels.
