规模化奶牛场温室气体排放量评估

Evaluation of greenhouse gas emissions from scale dairy farm

为了对组织层次上温室气体排放进行量化,为企业选择最有效的减排措施提供依据。该文以河北保定一规模化奶牛场为案例,利用气候变化框架公约(UNFCCC)清洁发展机制理事会批准的相关方法学、IPCC排放系数法及相关文献,在组织层次上量化了该奶牛场运行过程中的温室气体的排放与清除。案例研究结果表明,采用规模化运行管理方式及粪便管理系统时,该2300头存栏的奶牛场年排放温室气体为11333.2tCO2-e或者说每头存栏奶牛年排放温室气体4.9tCO2-e,并提出了组织温室气体的减排建议。这对同类牛场温室气体排放量的评估具有参考意义。

In order to quantitative greenhouse gas（GHG）emissions at the organization level and provide the most efficient GHG mitigation measures for enterprise,a scale dairy farm was studied in Baoding of Hebei Province.Based on scenario analysis,the detailed greenhouse gas emission and removals inventory were assessed at the organization level using methodology approved by executive board（EB）of clean development mechanism（CDM）under United Nation framework convention on climate change（UNFCCC）,IPCC emission coefficient and related literature.Case study indicated that using traditional operating management and current manure management system,the greenhouse gas emission was estimated to be 11 333.2 t CO2-e per year or 4.9 t CO2-e/head per year with 2 300 dairy cattle.Some mitigation measures have been proposed to reduce GHG emissions.It has significance in emission reduction of same scale dairy farm.
