该生命周期环境成本分析（LCECA）模型的目标是将生态成本纳入产品的总成本。生态成本是指产品在其整个生命周期中对环境造成的直接和间接成本。随后，该LCECA模型确定了具有成本效益的生态友好型零件/产品的可行替代品。这试图将成本计算纳入生命周期评估（LCA）实践。最终，它的目标是在任何产品生命周期的所有阶段，借助绿色或生态友好的替代品来降低总成本。成本细分结构的新生态成本类别包括八项生态成本，即污水/废物处理成本、污水/废物控制成本、废物处置成本、实施环境管理系统成本、生态税成本、恢复成本（在环境事故的情况下）、可再生能源利用的成本节约以及回收和再利用战略的成本节约。开发一个合适的成本模型和识别可行的替代方案是同时进行的。将使用基于多个环境标准的各种检查表，以确保替代品的生态友好性质。根据计算出的环境影响指数，将优先选择合适的替代品。LCECA的数学模型旨在定义产品的总成本与产品生命周期相关的各种生态成本之间的关系，并确定上述成本之间的定量表达式。已经开发了一个计算LCECA模型来比较替代方案的生态成本。该模型将包括评估替代方案的盈亏平衡分析，以及敏感性分析和风险分析模块。这种模式的目标是成本效益，生态友好的产品作为最终结果。该LCECA模型将与现有的LCA软件工具兼容。
The objective of this life cycle environmental cost analysis (LCECA) model is to include eco‐costs into the total cost of the products. Eco‐costs are both the direct and indirect costs of the environmental impacts caused by the product in its entire life cycle. Subsequently, this LCECA model identifies the feasible alternatives for cost‐effective, eco‐friendly parts/products. This attempts to incorporate costing into the life cycle assessment (LCA) practice. Ultimately, it aims to reduce the total cost with the help of green or eco‐friendly alternatives in all the stages of the life cycle of any product. The new category of eco‐costs of the cost breakdown structure includes eight eco‐costs, namely cost of effluent/waste treatment, cost of effluent/waste control, cost of waste disposal, cost of implementation of environmental management systems, costs of eco‐taxes, costs of rehabilitation (in case of environmental accidents), cost savings of renewable energy utilization, and cost savings of recycling and reuse strategies. Development of a suitable cost model and the identification of the feasible alternatives are performed simultaneously. Various checklists based on multiple environmental criteria will be used to ensure the eco‐friendly nature of the alternatives. On the basis of the calculated environmental impact indices (EII), priorities will be made for the selection of suitable alternatives. The mathematical model of LCECA aims to define the relationships between the total cost of products and the various eco‐costs concerned with the life cycle of the products, and determine quantitative expressions between the above‐said costs. A computational LCECA model has been developed to compare the eco‐costs of the alternatives. This model will include a break‐even analysis to evaluate the alternatives, and sensitivity analysis and risk analysis modules. This model aims at a cost‐effective, eco‐friendly product as an end result. This LCECA model will be compatible with the existing LCA software tools.
