본 연구에서는, 환경산업연관표 분석모형을 활용해, EU 탄소국경조정이 전면 도입될 경우의 국내 산업별 탄소국경조정 부담액 규모를 산정하고 국내 저탄소 정책 시행에 따른 산업별 부담액 변화를 비교 분석함으로써 기후변화 리스크에 대응한 중장기전략 수립에 시사점을 제시하고자 하였다. 분석 결과 EU 탄소국경조정 전면도입 정책충격에 따른 국내 산업 총부담액은 2030년 기준 약 8조 2,456억 원 규모로 예측되었다. 업종별 영향을 살펴보면 석유화학, 석유정제, 운송장비, 철강, 자동차, 전기/전자/정밀 산업으로 등 6대 주요 산업군에서 총탄소국경조정 총부담액의 84.3%를 차지하는 것으로 전망되었다. 그리고 저탄소 정책 시행에 따른 기술발전 및 에너지 전환을 가정한 복수의 정책 시나리오에서는 탄소국경조정 총부담액이 약 11.7%~15.0% 감소할 것으로 전망되었다. 본 연구의 주요 분석 결과는 탄소국경조정의 전면도입 확대에 따른 대응전략 수립을 특정 분야에 한정해 이행하는 것이 아니라, 종합적 접근 하에서 이뤄내 국가 경제 전반에 끼치는 부정적 영향을 최소화하고 새로운 성장동력을 발굴하는 기회의 창으로 활용할 필요가 있음을 시사하고 있다.

한국은 2015년부터 총 국가배출량의 60%를 차지하는 탄소 배출권 거래제를 시행하고 있다. 선진국에서 탄소가격 정책은 다양한 사회경제적 구성 집단 사이의 소득 불균형을 심화시키는 것으로 밝혀진 바 있다. 현재 한국 사회는 분배적인 문제뿐 아니라, 에너지 안보, 기후변화 대응, 경제 성장 등 다양한 과제에 직면하고 있다. 이런 상황에서 탄소가격정책이 소득 분배적인 측면에 미칠 영향을 분석하고, 이 분석결과를 바탕으로 대응책을 마련할 필요가 있다. 가계동향조사자료와 환경투입산출분석(EEIO)을 이용해 분석한 결과 저소득 가구, 노인가구와 도시가구가 탄소가격정책으로 인해 상대적으로 무거운 부담을 지는 것으로 나타났다. 그러나 세수의 일부가 가구에 재분배 될 경우 이러한 부담은 경감될 수 있을 것으로 분석되었다.

The question of how to establish sustainable agricultural systems has become as prominent as questions related to water, energy and climate change. High input/high output agriculture has brought with it many adverse effects; the massive deterioration of soil and water in both quantity and quality, increased greenhouse gas emissions and an increased prevalence of unsafe foods. Additionally, urbanization and climate change has worsened the shortage of farmland and reduced the supply of agricultural water. Given these challenges, maintaining, conserving and efficiently using agri-environmental resources, through fostering of sustainable agriculture, have emerged as key tasks in solving these problems. What is needed therefore is research, based on systematic and comprehensive empirical analyses, that can propose plans and methods for establishing an appropriate sustainable agricultural system. The empirical analysis of sustainable agricultural system is approached separately from economic, environmental and social aspects. An analysis of environment effect reveals that the available phosphate level is 1.3~2.1 times greater than the optimal amount in rice paddies, upland fields and orchards. Further examination has revealed that the excess nutrient is polluting both ground water and surface water. Analytical results for economic feasibility show that factors of production have been invested heavily in the rice crop. Under these conditions, sustainable agriculture, including low-input agriculture, appears to be a possible alternative that will facilitate simultaneous improvements in both economic feasibility and environment effects. Analysis results for sociality reveal that social factors include the value of producer, association and interior networks. Social conditions are comprised of leadership, consumers' awareness, education and conflict solutions. In addition, analysis as to the degree investments contribute to improving agricultural value added has revealed that the direct payment program is the most effective instrument. Experts confirm that economic feasibility can be improved by scientific and well-reasoned nutrient management on the basis of soil testing. Farmers pointed to 'economic factors' as being the largest obstacle to switching to the practice of sustainable agriculture. They also indicate 'uncertainty with regards to sustainable agriculture technology' as an impediment to practicing sustainable agriculture. Even so, farmers who believe environmental and regional issues to be the most pressing problems have expanded their practice of sustainable agriculture. The keys to establishing sustainable agriculture system are classified into the following four aspects. Firstly, from an economic aspect, the research indicates that agricultural policy needs to be integrated with environmental policy and that the function of market making based on the value chain needs to be revitalized. Secondly, from an environmental aspect, there is a need for an optimal resource management system to be established in the agricultural sector. In addition, sustainable agriculture practice will need to be extended with attendant environmentally-friendly and sustainable intensive technology also requiring further development. Thirdly, from a social aspect, green agriculture management needs to be fostered, technology and education extended, and social conflict mediated. Lastly, from a governance aspect, it will be necessary to strengthen good governance, assign and share suitable roles and responsibilities, build a cooperation system and utilize community supported agriculture.

Globally, agriculture is one of the largest consumers and polluters of water resources, contributing to the unsustainable use of limited water resources. To reduce the resource use and environmental footprints associated with current and future food systems, researchers and policy makers have recommended the transition to sustainable and healthier diets and the reduction of food loss and waste along the food supply chain. However, there is limited information on the synergistic effects and trade-offs of adopting the two measures. In this study, we assessed the water-saving potential of the two measures in South Korea using environmentally extended input-output relying on the EXIOBASE database for the reference year 2020, along with scenario analysis to model the potential outcomes. Specifically, we analyzed scenarios where meat consumption was reduced by 30% and 50% and in combination with a 50% reduction in food waste at the consumption stage for each scenario. According to our findings, by considering individual measures of dietary change and food waste reduction, shifting to a diet with 30% and 50% less meat consumption could lead to reduction in water footprint by 6.9% and 7.5%, respectively, while 50% reduction in food waste at the consumption stage could save about 14% of water footprint. However, the synergistic effects of the two measures such as 30% less meat consumption and 50% food waste reduction, and 50% less meat consumption and 50% food waste reduction result to 20% and 24% reductions in water footprint, respectively. Moreover, our findings also showed that increasing food consumption with high environmental impacts could promote resources use inefficiency when waste occurs. Thus, policy strategies that address synergistic effects of both dietary change and food waste reduction should be strengthened to achieve sustainable food system. International and national policies can increase resource efficiency by utilizing all available reduction potentials while considering strategies interactions.
