Path of value realization of carbon sink products in ecologically fragile areas from the perspective of low-carbon cycle:A case study of CERs project of household biogas in the four prefectures of Southern Xinjiang
Under the background of low-carbon cycle development,the value realization of carbon sink ecological products of agriculture,the countryside and farmers can promote the low-carbon development of agriculture,the countryside and farmers,and also benefit farmers.Taking the household biogas project in the four prefectures of southern Xinjiang in the ecologically fragile area as the research object,and based on the perspective of low-carbon cycle,the small-scale methodology AMS-Ⅲ.R and AMS-I.C were adopted to comprehensively calculate the dual carbon emission reduction benefits of greenhouse gases,estimate the economic benefits after participating in the CERs project d,and calculate the carbon emission reduction costs of the project,and finally the actual suggestions aiming at the actual regional situation were put forward.The results showed that in 2020,the total carbon emission reduction of household biogas project in the four prefectures of southern Xinjiang was 32.46 × 104 t/a,of which the first carbon emission reduction was 0.96×104 t/a,the second carbon emission reduction was 31.50×104 t/a,and the average carbon emission reduction per household was 1.12 t/a,the total economic income of farmers and herders participating in the CERs project was 33.85 million yuan,and the net present value of each household after participating in the CERs project was 2 229.6 yuan,the internal rate of return could reach 30％and the dynamic payback period was 3.16 years,the incremental cost per unit of carbon reduction(ICER)was 9.01 yuan/ton CO2 equivalent,which was $ 1.42/ton CO2 equivalent.Therefore,the development of the household biogas CERs project is feasible and has great development potential,and participating the carbon trading market to realize the value as one type of carbon sink products of agriculture,the countryside and farmers will also promote regional ecological restoration,carbon reduction and income increase,and consolidate the achievements of poverty alleviation.
