Abstract

This paper presents a model for parallel replacement and improvement for a fleet of assets to minimize both the economic costs and greenhouse gas (GHG) emissions where the emissions are limited by an emissions trading system also known as cap-and-trade. The firm which owns the assets has the options of using, storing, improving, or salvaging them. Different technological types and their performances have been considered for the assets. The firm has the option of purchasing new assets from varying technologies and/or improving its existing assets to a higher-performance type. The model considers the possibility of both banking the emission allowances or trading them in the market. The model was applied to data from a fleet of excavators in Ontario, Canada. The model and the findings of this case study could help emitter firms to simultaneously manage the emissions and costs of their assets in a jurisdiction regulated by cap-and-trade.

摘要

本文提出了一种模型，用于并行替换和改进资产组，以最小化经济成本和温室气体（GHG）排放，其中排放受排放交易系统（也称为总量控制和交易）限制。拥有资产的公司可以选择使用，存储，改善或挽救它们。资产已考虑了不同的技术类型及其性能。公司可以选择从各种技术中购买新资产和/或将其现有资产改进为更高性能的类型。该模型考虑了将排放配额存入银行或在市场上进行交易的可能性。该模型已应用于来自加拿大安大略省的一系列挖掘机的数据。
