Carbon sink assessment of bivalve and seaweed mariculture based on life-cycle carbon emissions:A case study of Zhanjiang City,Guangdong Province
摘要
Abstract
Zhanjiang City,with an area of 37 000 hm2 of mariculture,is an important production and processing base for aquatic products in Guangdong Province and even in the whole country.Conducting carbon sink accounting for mariculture bivalve and seaweed is of great significance,as it will provide data support for Zhanjiang City to conduct fishery carbon sink trading in the future and meet the national carbon neutral demand.Based on the field surveys and laboratory analysis,the key basic data of carbon sink accounting of native bivalve and seaweed in Zhanjiang was obtained in this study.And the carbon sink capacity of mariculture in Zhanjiang based on the whole life cycle carbon emissions of bivalve and seaweed were also evaluated.The results showed that the total carbon sink(measured in CO2)of mari-culture bivalve and seaweed in Zhanjiang was 155 436 t in 2021,with bivalve accounting for 155 359 t and seaweed accounting for 77 t.According to the current CO2 trading price in China's blue carbon market,the economic value created by the carbon sinks of bivalve and seaweed in Zhanjiang was 16.48 million RMB.Using the comprehensive method of carbon emission in the whole life cycle assessment,the net carbon sink of the bivalve in Zhanjiang City was 135 176 t,and the seaweed was 39 t.It is evident that Zhanjiang City has a high carbon sequestration capacity in marine bivalve cultivation,which can bring significant economic benefits through emission reduction,and making an important contribution to China's climate change solutions and achieving the"dual carbon"goals.关键词
