This PAS specifies requirements for the assessment of the life cycle GHG emissions of goods and services (collectively referred to as “products”) based on key life cycle assessment techniques and principles. This PAS is applicable to organizations assessing the GHG emissions of products across their life cycle, and to organizations assessing the cradle-to-gate GHG emissions of products. Requirements are specified for identifying the system boundary, the sources of GHG emissions associated with products that fall inside the system boundary, the data requirements for carrying out the analysis, and the calculation of the results. This PAS addresses the single impact category of global warming, and does not assess other potential social, economic and environmental impacts arising from the provision of products, such as non-greenhouse gas emissions, acidification, eutrophication, toxicity, biodiversity, labour standards or other social, economic and environmental impacts that may be associated with the life cycle of products. The life cycle GHG emissions of products, calculated using this PAS, do not provide an indicator of the overall environmental impact of these products, such as may result from other types of life cycle assessment. This PAS does not include product category-specific rules for goods and services; however, it is intended that selected product category-specific rules for goods and services, developed in accordance with BS ISO 14025, will be adopted where available, as specified in this PAS. It is one of the intentions of this PAS to allow for the comparison of GHG emissions between products, and to enable the communication of this information. However, this PAS does not specify requirements for communication.
《报告》通过对厨余垃圾全生命周期多种处理方式产生的温室气体排放等相关数据进行研究分析,提出低碳处理厨余垃圾,需要优先减少前端食物浪费,在妥善进行垃圾分类和资源回收利用的基础上,按照“厌氧消化>好氧堆肥>焚烧>填埋”的顺序优化后端处置方式。 食物浪费加剧气候变化 从前端食物浪费,到后端的厨余垃圾处理,都会产生资源消耗、环境污染和温室气体排放。...
也就是说,燃料的碳强度应从能源原料的获取开始计算,包括开采(种植)、生产、运输以及最后汽车发动机燃烧,整个过程的温室气体排放都应包括在燃料碳度内,并不是只考虑汽车发动机的燃烧排放。而且,温室气体的排放可能因其中任何环节的改变而产生较大的变化,同一种燃料的碳强度是可以通过工艺改进、技术创新来降低的。...
PAS 2050在国际上被企业广泛用来评价其商品和服务的温室气体排放。标准可以帮助实现测量和减少整个供应链的碳排放、信息透明度、可靠性和一致性的需要,因此帮助公司、客户和其他利益相关方在第一时间采取对于环境有益的恰当决策,同时可以为企业赢得信誉。“碳足迹”是用来对抗气候变化的一个重要工具。它让个人和组织能够评估自己对环境造成的影响,也能了解自己在哪些地方排放了温室气体,是评估未来的减排计划的基础。...
这意味着,这一产业很可能已经还清了能源消耗和温室气体排放中的“欠债”——即便没有,距离收支相抵也已十分接近。 研究人员对太阳能电池板产业进行了全生命周期评估,并将其模型与联合国和国际能源署的数据库进行了比较。他们还分析了模型中的不确定因素:在模型中的最坏情况下,这一产业将在2017年追平能源消耗,并有望在2018年还清温室气体排放“债务”。...
