Abstract：
Achieving net zero emissions to ensure a sustainable future has become increasingly urgent in light of climate change. The palm oil industry in Malaysia plays a significant role in the country\'s economy but has faced criticism for its environmental impact, particularly in terms of sustainability and greenhouse gas emissions. While the government has implemented policies and initiatives to promote sustainable palm oil production and reduce emissions, there remains a need for a comprehensive and integrated mitigation strategy to help make an informed decision to improve the performance. To address the limitations of the current framework, this study proposes an Integrated Mitigation Strategy Model which incorporates established frameworks of Palm Oil Mill Carbon Accounting (POMCFA) and Sustainability Index (POMSI). This model has been developed based on the superstructure approach, considering a set of mitigation options to improve weak indicators identified through assessments. The selection of these options is informed by a theoretical review of existing literature on factor changes and their impact on emissions reduction. The model is further validated through case studies, ensuring its robustness and reliability. Based on the case study, it reveals that palm oil mill effluent, diesel consumption, and water consumption contribute the most to carbon dioxide equivalent emissions. In terms of sustainability scoring, the environmental aspect obtains the lowest scores compared to social and economic aspects. Weaknesses identified include dust concentration, palm oil mill effluent, and boiler emissions. Using the heuristics of factor changes equation, the mitigation model suggests implementing high-technology boilers as the optimal solution for these weaknesses. With the theoretical and empirical support behind the choice of variables, our model provides a valuable tool for decision-making in achieving net-zero emissions and sustainable palm oil production.
摘要：
鉴于气候变化，实现净零排放以确保可持续的未来变得越来越紧迫。马来西亚的棕榈油产业在该国经济中发挥着重要作用，但因其对环境的影响而受到批评。特别是在可持续性和温室气体排放方面。虽然政府实施了促进可持续棕榈油生产和减少排放的政策和举措，仍然需要一个全面和综合的缓解战略，以帮助做出明智的决定，以提高绩效。为了解决当前框架的局限性，本研究提出了一个综合缓解策略模型，该模型结合了已建立的棕榈油工厂碳会计（POMCFA）和可持续发展指数（POMSI）框架。该模型是基于上层建筑方法开发的，考虑一套缓解方案，以改善通过评估确定的薄弱指标。这些方案的选择是通过对现有有关要素变化及其对减排影响的文献进行理论综述而得出的。通过案例研究进一步验证了该模型。确保其鲁棒性和可靠性。根据案例研究，它揭示了棕榈油厂的废水，柴油消耗，水消耗对二氧化碳当量排放量的贡献最大。在可持续性评分方面，与社会和经济方面相比，环境方面的得分最低。确定的弱点包括粉尘浓度，棕榈油厂废水，和锅炉排放。使用因子变化方程的启发式方法，缓解模型建议实施高科技锅炉作为这些弱点的最佳解决方案。在变量选择背后的理论和实证支持下,我们的模型为实现净零排放和可持续棕榈油生产的决策提供了宝贵的工具。
