Recently, in the concrete industry, the development and commercialization of low-carbon products of ready-mixed concrete have emerged as part of the efforts to realize carbon neutrality. This study aims to investigate the current status of environmental product declaration(EPD) of ready-mixed concrete and to analyze the characteristics of carbon emissions by compressive strength, life cycle stage, and region. To this end, the related certification system requiring the calculation of carbon emissions in the concrete industry was analyzed. The target of analyzing the current status of carbon emissions was set as a product of ready-mixed concrete that acquired EPD certification based on the life cycle assessment method. In addition, the trend of carbon emissions according to each characteristic was reviewed by analyzing carbon emissions by the life cycle of ready-mixed concrete products, analyzing carbon emissions by standard, and analyzing carbon emissions by region. As a result, the carbon emissions in the pre-production stage were 99% compared to total carbon emissions., and as it increased from 18MPa to 40MPa, carbon emissions also increased. Even with the same specifications, the carbon emissions in the capital region were higher than in the southern region.

15 carbon footprint product (CFP) schemes, including Korea Carbon Footprint Label, UK Carbon Trust's Carbon Reduction Label and Japan CFP are implemented in the world. A CFP describes green house gases (GHGs) emissions emitted throughout product's life cycle and is intended to reduce GHGs emissions by labeling a CFP result on product. This study calculates Korea, UK and Japan CFP result of vacuum cleaner, detergent, packagin material in order to analyze the Korea, UK and Japan CFP standards. Our results demonstrate significant differences among then calculated results because of criteria, emission factors, etc. Therefore, there are many difficulties in providing various CFP results and the international standard and guidelines for product category are needed.

The Product Carbon Footprint Labeling has been run for more than four years by the Ministry of Environment and there are number of products labeled by KEITI(Korea Environmental Industry & Technology Institute), as for declaring products with their carbon emission during life cycle stages. There are several categories for certifying products by the characteristics of usage. Building products which are applied to a building as combined components or elements, are classified as production goods which means that the products are chosen by a business, not by a final consumer. In this paper, current status of PCF labeling has been reviewed focused on building products and the characteristics of carbon emission by a kind of product such as interior products, window products, structural products, system products and others. Until Dec. 2013, 82 products has been labeled and it covers about 53% among labeled product goods by the certification. Among the labeled building products, interior products are main products. From the results of comparison, variations of emission amounts by products have been found and the cause of variation could be explained by the purpose and material properties of products. However, the exact reason for variations cannot be acquired because of lack of information and the short operation period of the certification program. Further studies and more products are needed to be studied and analyzed focused on the emission characteristic by each product and to suggest reduction technologies for sustainable building products.

내연기관 자동차는 연료 소모로 인해 대기 중에 유해 물질과 온실가스를 배출한다. 반면에 전기 자동차는 전기로 작동되어 대기 중 오염을 줄이고 친환경적인 운행을 제공한다. 전기차 대여 시스템을 도입함으로써, 사용자들에게 친환경적인 교통수단을 이용할 수 있는 기회를 제공하고, 탄소 배출량을 줄이는 데 크게 기여할 수 있기에 해당 연구를 진행하였다. 이 연구에는 React 기반의 Next.js 웹 프레임워크를 이용하여 클라이언트 측과 서버 측 렌더링을 지원하고 사용자들에게 빠른 반응 속도와 사용 편의성을 제공한다. Bootstrap을 이용하여 사용자 인터페이스(UI)를 개발하고, 전기 자동차 대여 서비스에 필요한 화면을 구성하였다. 또한 Node.js 기반의 Express.js 웹 프레임워크를 이용하여 서버 사이드 로직과 RESTful API를 개발하는 데 사용하고 데이터베이스와의 통신, 사용자 인증, 대여 정보 관리 등을 처리하였다. 이러한 기술적 개발을 통해 전기 자동차 대여 시스템은 실용적이고 효율적인 서비스를 제공하며, 환경 보호와 탄소 배출 감소에 기여할 수 있는 프로젝트라고 볼 수 있다.
