Study of Aquaculture Carbon Emissions in Zhejiang Province Based on the Long-range Energy Alternatives Planning System Model
In order to understand the current situation and development trend of energy consumption and carbon emission of aquaculture indus-try,based on LEAP model,constructed LEAP aquaculture model of Zhejiang Province and analyzed the trend of energy consumption and car-bon emission of aquaculture industry in Zhejiang Province under baseline scenario,low carbon scenario and enhanced low carbon scenario. The results showed that in terms of energy consumption,the total energy consumption of the future aquaculture industry in Zhejiang Province under the baseline scenario showed an increasing trend,and the composition of energy consumption was mainly based on fossil energy,with coal always being the most dominant energy demand. Carbon reduction measures had a certain energy-saving effect,in which the enhanced low-carbon scenario 2035 was 15.24% more energy-efficient than the baseline scenario,saving approximately 25.11×103t. In terms of final energy consumption structure,pond farming and feed production consumed the most energy,with energy consumption exceeding 30% of total energy consumption in all scenarios and years.From the perspective of carbon emissions,aquaculture in Zhejiang Province was more inclined to carbon sink attributes,and carbon reduction measures had a certain effect on carbon emission suppression. In terms of emission reduction contribution,the carbon reduction measures considered were able to reduce CO2 emissions,with energy efficiency improvement and clean en-ergy generation promotion playing a key role in aquaculture carbon reduction,contributing 20.9% and 64.5% of carbon reduction by 2035.
