Abstract

Accounting for potential GHG emissions from the palm oil production is essential to demonstrate partly how responsible palm oil production can be carried out. Results of the GHG emission calculation from certified RSPO members using the RSPO PalmGHG Calculator are collated and reported. The potential sources of GHG emission that result directly from production of palm oil are enumerated. The cumulative impact, which affects the final carbon balance in the production of crude palm oil (CPO), is quantified. The analysis helps to identify GHG emission hotspots so that mitigation plans can be developed and implemented. The aim is to minimise and reduce GHG emissions that result from production of palm oil. The emission from planting on peat, land conversion, and POME are the major sources of emission in CPO production. Peat is the most dominant contributing factor to GHG emission. Land conversion emission is dependent on the type of land cover which was converted to oil palm. Converting land cover with higher carbon stocks such as secondary forest to oil palm will cause higher GHG emission than converting land cover with lower carbon stocks such as shrubland. Emission from POME is significant and construction of methane capture can reduce the POME emission significantly. Sequestration from conservation areas and emission credit from export of biomass and electricity has a moderate positive impact on the GHG emission. Emission from existing certified RSPO plantations during the period of January 2015 to August 2017 is 3.33 tCO2e/tCPO for peat area and 0.94 tCO2e/tCPO for non-peat area. This is lower compared to average GHG emissions of the oil palm industry of 10. 6 tCO2e/tCPO for peat area and 1. 73 tCO2e/tCPO for non-peat area. Keywords: LCA, RSPO, PalmGHG, GHG emissions, palm oil.
Rspo计算棕榈油生产过程中温室气体排放量的方法
考虑棕榈油生产中潜在的温室气体排放,对于在一定程度上证明如何进行负责任的棕榈油生产至关重要。使用RSPO PalmGHG计算器对认证RSPO成员的温室气体排放计算结果进行整理和报告。列举了棕榈油生产直接导致的潜在温室气体排放源。对棕榈油生产过程中影响最终碳平衡的累积影响进行了量化。该分析有助于确定温室气体排放热点,以便制定和实施缓解计划。其目的是尽量减少棕榈油生产产生的温室气体排放。在CPO生产中,泥炭种植、土地改造和POME排放是主要的排放源。泥炭是温室气体排放的最主要因素。土地转化排放取决于被转化为油棕的土地覆盖类型。将碳储量较高的土地覆盖(如次生林)转化为油棕将比将碳储量较低的土地覆盖(如灌木地)转化为温室气体排放更高。POME的排放是显著的,甲烷捕获的建设可以显著减少POME的排放。保护区的固存和生物质和电力出口的排放信用对温室气体排放有适度的正向影响。在2015年1月至2017年8月期间,现有认证的RSPO人工林的排放量为泥炭区3.33 tCO2e/tCPO,非泥炭区0.94 tCO2e/tCPO。这比油棕行业的平均温室气体排放量低10%。6 tCO2e/tCPO泥炭区和1。非泥炭地区co2e / tcp为73 tCO2e/ tcp。关键词:LCA, RSPO,棕榈温室气体,温室气体排放,棕榈油
