為了達成環境永續的願景，如何減少車輛的產生及可回收零件的重覆利用將會是有效降低碳排放量的重要任務。本論文透過以區塊鏈建立非同質化代幣(以下簡稱NFT)的方式，讓賣家在販售車輛時能夠提供完整的生產履歷，期待可為二手車市場達成防範不實車輛資訊的功能。當車輛進入二手拍賣市場時，讓消費者可藉由透明且具公信力的生產履歷，了解這部車輛從生產、交易到拍賣之間總共經歷的維修紀錄以及詳細資訊之外，並可加速車輛擁有權及相關資訊驗證。如此一來，可避免大量的紙張浪費及提高使用者購買二手車意願，另外車輛零件的使用記錄也可明確有效地記錄著，故可回收利用零件的機會也將大大地提升，故可改善環保議題。

In order to achieve the vision of environmental sustainability, how to reduce the production of vehicles and reuse of recyclable parts will be an important task to effectively reduce carbon emissions. In this paper, by establishing a non-fungible token (referred to as NFT) on the blockchain, the seller can provide a complete production history when selling vehicles, hoping to achieve the ability of preventing false vehicle information in the used car market. When a vehicle is listed in the second-hand auction market, consumers can take advantage of the transparent and credible production history to understand the whole maintenance records and the detailed information of the vehicle from production, transaction to auction, and to speed up the verification of the car ownership and its corresponding information. In this way, a lot of paper waste can be avoided and users' willingness to buy used cars can be increased. In addition, the service records of vehicle parts can also be clearly and effectively recorded, so the chances of recycling parts will also be greatly improved. In the end, the proposed method should be a decent method to address environmental protection. issues.
