국내의 탄소중립 정책은 다분히 온실가스 감축정책 위주로 구성되어 있는 것에 반해 미국, 영국, 중국 등 탄소중립을 선언한 국가는 경제성장과 기후변화를 동시에 달성하겠다는 목표를 갖고 있다. 본 논문은 온실가스 배출의 넷제로를 의미하는 탄소중립 개념을 램지의 경제성장 모형에 포함함으로써 탄소중립 정책이 자본축적의 장기적 동태적 과정에 미치는 효과를 분석하였다. 아울러 지속가능한 경제성장을 달성하기 위한 이른바 하트윅 규칙을 내포하였다. 넷제로의 탄소중립이 자본과 소비 경로의 정상상태와 더불어 나타날 때의 정상상태 균형을 분석하였다. 분석 결과를 보면, 램지 모형에 탄소중립과 하트윅 규칙을 포함할 경우 자본의 축적이 저규모 수준에서 정상상태에 도달하는 것으로 나타났다. 또한 재생에너지 확대가 다수의 이해집단에 의해 지대추구 대상이 될 때에는 자본축적 규모가 보다 더 악화될 수 있기 때문에, 에너지 전환과정에 공정한 시장제도 설계가 중요함을 알 수 있다.

Carbon Neutral is one of the magnifying pan-governmental tasks which aim for stabilizing pan-global ecosystem. The purpose of this study is to estimates carbon neutral degree in cities by using capacity of carbon storage, which is carbon sinks, on forest and to develop an indicator that could be utilized in establishing policy related to climate change respond. When the carbon emitted from city has been absorbed or stored, the value of the indicator aiming to achieve carbon neutral could be drawn. The result and implication are as follows. First, while the annual amount of carbon emission in Gyeonggi S city was 18,787 thousand (tons), which was the highest, that of Gyeongbuk U city indicated the lowest with approximately 112 thousand (tons). Second, Gyeongbuk U city represented the largest capacity of annual carbon storage with about 16,748 thousand (tons), whereas the smallest figure was shown in Gyeonggi B city with 151 thousand (tons). Third, as result of the estimation of carbon neutral degree, the value of the indicator in Gyeonggi B city was 3% referring the lowest point, while that of other cities demonstrated over 100%. Forth, it has the possibility to suggest the fixed quantity when the plan for achieving carbon neutral of city is being processed. In the near future, after the completion of the construction projects of greenhouse gas inventory in all local governments, by utilizing the relative dates, the value of the indicator can be calculated and a more general conclusion could be drawn. Moreover, as expanding case studies to all domestic cities, generalness is in need.

Climate action is at the top of the agenda in the international community, as demonstrated at the 2021 G7 Summit and the 2021 UN Climate Summit. Major developed countries are scrambling to make a transition to a green economy and create a new growth momentum. Following the Paris Climate Agreement in 2016, they focus on "carbon neutrality" as an effective means of tackling climate change. The Republic of Korea, a high-carbon economy, submitted its second Nationally Determined Contribution and announced carbon neutrality as a top policy priority. Accordingly, the country increases government budget in research and development (R&D) and science and technology (S&T) policies. Against this backdrop, this study analyzed policies on carbon-neutral S&T and R&D in major advanced countries. The analysis was made by identifying globally pending issues in carbon-neutral policies and climate technology. In addition, focus group interviews were conducted six times with 10 experts to come up with three R&D strategies and action plans for government-funded research institutes to achieve carbon neutrality. To be specific, the following measures were suggested. First, creative and innovative R&D programs are required to solve the problem of carbon emissions. Second, it is necessary to establish carbon neutrality policies and infrastructure which are sustainable to run and manage. Third, it is crucial to promote cooperation in climate technology based on excellence. In conclusion, the strategies proposed in this study are expected to provide directions and implications for policymakers, researchers, and scholars in science and technology to develop effective strategies to achieve national carbon neutrality.

Gwangju Metropolitan Government & Ministry of Environment have signed a model city in response to Climate Change agreement. The agreement calls for Gwangju to cut greenhouse gas emissions 10% below 2005 levels by 2015. Gwangju has seen this agreement as an opportunity to cut pollution and conserve the environment as well as to reinvigorate local economy. According to policy of Gwangju, Gwangju held design competition for Gwangju City Arboretum on march, 2009. The purpose of design competition was to give a wide publicity to Gwangju as Hub City of Asian Culture and construct carbon-neutral arboretum in accordance with the policy of 'Low-Carbon and Green Growth'. First of all, a design concept of arboretum is 'winding, round, overlay 'to reflect the landscape of Nam-do which is surrounded by mountains and river flows through the village. Second, the arboretum has five different places with these themes - Forest of Festivals, Health, Nature, Nostalgia, Education and Future. Each place has a symbolic theme park and different flow planning respectively. Third, the most critical point is that the arboretum is a carbon-neutral park. Gwangju arboretum will soon be developed in metropolitan sanitary landfill and constructed as the O2 arboretum based on low carbon strategy. Fourth, the O2 arboretum suggests specialized issue : 'Energy Saving', 'Recycling System', 'Green Network', 'Water System(rainwater maintenance and wetland development)'. Besides, main buildings(greenhouse, visitor center, Nam-do experience exhibition hall, and forest museum) is designed in consideration of harmony with topography character, surroundings. Also, planting will be a multilayer plant based on native landscape trees in consideration of function and the growth characteristics.

This paper investigates the interaction among the paradigm of Low-Carbon Society (LCS) and the megatrends in field of population, environment, geopolitics, and energy. The paradigm of LCS is regarded as a 'social will' trend, distinguished from other 'phenomenal' trends. The qualitative analysis shows that the megatrends and the LCS paradigm have positive/neutral/negative impacts on one another, while some impacts can be reversed to other types of impact with the conditions having ripened. In quantitative analysis, the correlation between the LCS paradigm and the economy is traced with our Integrated Assessment Model, looking into such response options as population control, increase in labor force participation, and productivity enhancement to maintain utility level despite the pursuit of LCS paradigm. The future challenges in national strategy and S&T policy are suggested, based on the interaction analyses.

Climate change has recently become a serious global issue, and carbon emissions and energy consumption are increasing, particularly in cities where economic activities and populations are concentrated. Accordingly, various countries worldwide are promoting the Green New Deal and promoting urban-centered climate change response policies with the aim of carbon neutrality. In Korea, following the "smart green city" project that creates a city where humans and the environment coexist, a similar "carbon neutral green city" policy is set to be introduced. Therefore, in this study, implications and directions for the sustainable introduction of the carbon neutral green city policy will be derived by comparing and analyzing the State and Tribal Assistance Grants of the U.S. bipartisan infrastructure law and the smart green city of the Korean new deal.

Carbon neutrality has been suggested to overcome the global climate crisis caused by global climate change. Hydrogen energy is a major way to achieve carbon neutrality, and the developments and policies of hydrogen technology have been proposed to achieve this goal. To commercialize hydrogen energy resources, it is necessary to understand the overall value chain composed of hydrogen production, storage, and utilization and to present the direction of technological developments. In this paper the hydrogen strategies of major countries, including Europe, the United States, Japan, China, and South Korea will be analyzed, and hydrogen technologies by value chain will also be explain. This paper will contribute to understanding the overall hydrogen policy and technology, as both policy and technology are summarized.

기후변화에 대응한 국제사회의 실천과제인 탄소중립이 각국의 국가 미래 발전을 좌우하는 핵심 산업전략으로 옮겨가고 있다. G2의 경제 대국으로 성장한 중국이지만 고탄소 배출의 산업구조로 인해 이 같은 기후변화 글로벌 이슈를 선도하기 어려울 것이라는 일부 관측이 무색하게도, 중국은 탄소중립을 자국 산업경쟁력 강화를 위한 수단으로 활용하고 있다. 중국정부는 탄소중립 달성을 위한 국정 방침과 이를 이행하기 위한 분야별 세부 계획을 수립, 특히 탄소중립 산업전략을 통해 외부로부터의 기후대응 국제규범 외압을 자국 산업구조의 조정과 신산업 육성을 위한 지렛대로 삼고자 한다. 그러나 이 같은 탄소중립 산업전략은 지역별 경제·산업 수준 등 여건에 따라 중점분야 및 집행력에서 차이가 있을 것으로 예상된다. 이 글에서는 중국 지역별 탄소중립 이행여건과 주요 산업정책의 내용 및 특징을 분석한다. 상이한 경제발전 수준과 산업구조 등에 따라 지역별 탄소배출 규모, 배출원, 효율성에 상당한 차이가 있을 수밖에 없다. 이는 중앙으로부터 주어진 탄소중립 목표를 이행하는 데 있어 상이한 초기 조건과 내생적 요소를 부여하게 되며, 이 같은 주어진 구조적 요인들은 각 지역에 유리한 탄소중립 산업전략의 방향과 중점정책의 조성 및 추진을 제약하게 된다. 특히 탄소중립 이행 관련 지방정부의 정책 자율성 정도를 제약함으로써, 중앙-지방 환경거버넌스의 지역별 특징이 나타날 것이다. 이 같은 점은 보다 정확한 중국 탄소중립 향방을 탐색하기 위해서 국가를 단위로 한 총괄적 연구와 더불어 지역별 모니터링이 긴요함을 시사한다.

The aim of this dissertation is establishing internal indicator list for achieving policy goal of Carbon Neutrality Green City. First of all, it started to construct the basic system of planning indicator based on through comprehension of current studies such as advanced researches, government guidelines and green building certifications. And then it was set up final indicator list through inspecting FGI (Focus Group Interview), Verification of suitability, and Analysis of importance). As a result of this research, the planning indicator divided three steps and there were classified four fields in the top-level; Green Land and Ecology, Green Energy, Green Resource and Transportation, Green Living and Institution. According to the data, it deducted four items (ratio of green land, site plan, heat island and management of climate, base of nature ecology) and twelve index in the field of green land and ecology, three item(energy conservation and self-supporting, energy efficiency, new regeneration energy) and twelve index in the field of green energy and regeneration, five items(water resources utilize and circulation, other resource reduction and circulation, public transportation, green transportation plan) and fifteen index. Totally, Planning Indicators of forty nine were deducted. Therefore, there was the result of importance analysis that the indicators of plan and maintain management as the side of space for carbon neutrality were more appreciated than carbon reduction of individual building.
