  • This study was carried out to estimate carbon footprint and to establish of LCA of garlic production system. We have case study in cultivate garlic 1 kg calculate in carbon footprint. LCA carried out to estimate carbon footprint and to establish of LCI (life cycle inventory) database of garlic production system. The data is from Research of Farmer's income in 2010 (RDA, 2011), and used Pass (5.0.0) program. The value of fertilizer, amount of pesticide input were shown the environmental effect and direct emission. Carbon footprint in agriculture guarantees the choice right the consumer to choose the lower carbon goods. Its can make to strengthen of agriculture and food industry's reduction effort of $CO_2$. Nowadays consumer requests food's safety and environment friendly process. Carbon footprint also needs consumer's relief and incentives.

  • The goal of this study, as an effort to reduce national greenhouse gas (GHG) emissions, is to calculate the carbon footprint of students based on the commute pattern of high school students in big (Seoul), middle (Suwon) and small (Icheon) size city. By conducting a survey, the commute pattern and method of students as well as students' carbon footprint were evaluated. As a result, the carbon footprint of the high school student in Icheon ($1.698kgCO_2$) had 2~3 times higher than student's carbon footprint in Seoul ($0.623kgCO_2$) and Suwon ($0.699kgCO_2$). One of the reasons for the different carbon footprint result between big and small city was whether the public pedestrian facilities and a bicycle path or not. Based on our research results, we pointed out the problems and suggested some ways to reduce carbon footprint of students.

  • 본 연구는 지구과학교육을 전공하는 예비교사들에게 SDGs(지속가능발전목표)와 연계된 ESD(지속가능발전교육)을 적용하기 위한 기초 연구이다. 연구의 목적은 예비교사가 내면화 하고 있는 탄소발자국에 대한 인식과 태도 및 지식, 주관적 규범 및 행동 통제를 분석하여 탄소 소양을 평가하는 것이다. 예비교사들은 탄소 발자국을 자신의 책임으로 인식하고 있지만, 비용을 지불하고 불편을 감수하는데 소극적인 이중적 태도를 갖고 있다. 또한 탄소 발자국을 줄이기 위한 행동을 지지하지만, 요구하지는 않는다. 탄소 저감 행동에 대한 상식은 충분한 반면, 지구 온난화의 원인과 결과에 대한 개념은 불안정하다. 예비교사들은 학교 현장으로 배출되어 수많은 학생들에게 지구 온난화 문제를 가르치게 될 것이다. 따라서 탄소 발자국을 줄이는 경제적 비용과 사회적 책임에 대한 소양 교육이 필수적이며, 생각과 행동 사이의 간극을 메울 수 있는 방법을 찾아야 할 것이다. 예비교사들의 탄소 소양(carbon literacy)에 대한 연구로부터 ESD로 이어지는 교육이 실현되기를 바란다.

  • The product-level carbon footprint (PCF) is a comprehensive and widely accepted metric for sustainable product development. However, since a full PCF study in general is time and cost intensive, it is not feasible for the product development team to synchronize the activity to the main product development process. In addition, the current dedicated life cycle assessment (LCA) tools for calculating PCF, separated from the main product data management systems, have limitations to provide timely PCF information for design decision makings and collaborations between design and environment engineers. This paper examines the possibility of the extension of the current product data model that can support the PCF calculation with PDM (Product Data Management) databases. The product data model can represent not only the content of products but also context or system information of the products. The product data model can be implemented as a PDM database that can satisfy the needs for handy and timely PCF calculations from the consistent product data for dynamic design decision makings and engineering collaborations.

  • 사범대학에 개설된 교양 강의를 통해 지속가능발전목표(SDGs)와 연계하여 지속가능발전교육(ESD)을 실시한 사례를 소개하고자 한다. SDGs 13번 목표인 '기후변화 대응'과 연계하여 설계된 수업에서 42명의 예비교사들이 표출한 탄소 발자국(carbon footprint)에 대한 인식을 분석하였다. 예비교사들은 일상생활에서 탄소를 배출하는 실천 정도에 대한 체크리스트인 탄소 다이어트 다이어리를 작성하고, 탄소 발자국 그리기 활동을 통해 자신이 배출하는 탄소의 출처와 비율을 자유롭게 표현하였다. 전기 사용, 대중교통 이용, 쓰레기 처리 항목에서는 긍정적인 실천 정도를 나타내었으나, 수도 사용에 대해서는 부정적인 방향으로 분석되었다. 탄소 발자국을 2-3가지 항목으로 표현한 예비교사들이 과반수에 달하여 자신의 일상생활에서 탄소 배출 상황을 인식하는데 한계를 나타내었다. 예비교사들은 학교현장에서 지구의 환경문제를 교육하는 주체가 될 것이며, 예비교사들의 탄소 소양(carbon literacy)은 학생들에게 직간접적 영향을 미치게 될 것이다. 17가지 SDGs와 연계되는 다양한 지속가능발전교육 프로그램이 개발되고 교육현장에 적용되어 지속가능한 지구환경교육에 기여하기를 바란다.

  • Reservoirs play a key role in the carbon cycle between terrestrial and marine systems and are pathways that release greenhouse gases(GHGs), CO2, CH4, and N2O, into the atmosphere by decomposing organic matters. Developed countries have been actively conducting research on carbon emission assessment of dam reservoirs for over 10 years under the leadership of UNESCO/IHA, but associated research is very rare in Korea. In particular, the GHGs footprint evaluation, which calculates the change in net carbon emission considering the watershed environment between pre- and post- impoundment, is very important in evaluating the carbon emission of hydroelectric dams. The objective of this study was to estimate the GHG emissions and footprints in Daecheong Reservoir using the G-res Tool, an online platform developed by UNESCO/IHA. The G-res Tool estimates CO2 and CH4 emissions in consideration of diverse pathway fluxes of GHGs from the reservoir and characterizes changes in GHG fluxes over 100 years based on the expected lifetime of the dam. The input required to use the G-res Tool include data related to watersheds, reservoirs, and dams, and most were collected through the government's public portal. As a result of the study, the GHG footprint of Daecheong Reservoir was estimated to be 93 gCO2eq/m2/yr, which is similar to that of other reservoirs around the world in the same climate zone. After impoundment, the CH4 diffusion emission from the reservoir was 73 gCO2eq/m2/yr, also similar to those of the overseas reservoirs, but the CH4 bubbling emission, degassing emission, and CO2 diffusion emissions were 44, 34, 252 gCO2eq/m2/yr, respectively, showing a rather high tendency. Since the dam reservoir carbon footprint evaluation is essential for the Clean Development Mechanism evaluation of hydroelectric power generation, continuous research is needed in the future. In particular, experimental studies that can replace the emission factors obtained from the overseas dam reservoirs currently used in the G-res Tool should be promoted.

  • This study investigates the environmental footprint impacts of nuclear energy consumption in the presence of environmental technology and globalization of the ten largest ecological footprint countries from 1990 up to 2017. By considering a set of methods that can help solve the issue of cross-sectional dependence, we employ the Lagrange multiplier bootstrap cointegration method, Driscoll-Kraay standard errors for long-run estimation and feasible generalized least squares (FGLS) and panel-corrected standard errors (PCSE) for robustness. The finding revealed significant negative effects of nuclear energy consumption, environmental-related technology, population density and significant positive effects of globalization and economic growth on ecological footprint. These results are also robust by assessing the long-run impacts of predictors on carbon footprint and CO2 emissions as alternate ecological measures. These conclusions provide the profound significance of nuclear energy consumption for environmentally sustainable development in the top ten ecological footprint countries and serve as an important reference for ecological security for other countries globally.

  • 과거 50여 년간 한국의 생태발자국(Ecological Footprint, EF)은 가파르게 증가해 왔으며, 이에 따라 오버슈트(Overshoot) 역시 증가해 왔다. 오버슈트를 야기하는 중요한 원인에는 인구 증가와 일인당 자원 사용 강도 증가가 있다. 본 연구에서는 이들 원인 가운데 어떤 변수가 지난 50여 년간 한국의 EF에 더 큰 영향을 미쳤는지에 대해 알아보았다. 소비 부문들 가운데, 에너지 소비에 따른 탄소발자국(Carbon Footprint, CF), 단백질 섭취에 따른 초지발자국(Grazing Land Footprint)과 어장 발자국(Fishing Grounds)이 EF 증가에 크게 영향을 주었다. 지난 50여 년간의 추세가 앞으로도 유지된다면, 2060년에는 일인당 EF 값이 2009년 현재의 2배에 달할 것으로 보이며, 2031년 이후 인구가 감소함에도 불구하고 1인당 EF 값의 증가에 따른 영향으로 EF는 2059년까지 증가할 것으로 보인다. 그러므로 향후 개개인의 소비 패턴과 행동 변화를 유도하는 것으로 환경관리 방향을 전환해갈 필요가 있을 것이다.
