앞으로 10년간 세계의 생물다양성 보전을 위한 유엔 생물다양성협약 당사국 총회가 2022년 12월 캐나다 몬트리올에서 열린다. 전 세계 전문가와 정책입안자들이 여러 내용을 다루지만 그중에서도 염기서열 정보에 관한 내용을 집중적으로 소개한다. 우선 생물다양성협약에서의 이익공유에 관한 내용은 북아시아 원산인 콩을 현재 대량으로 재배하고 수확하고 있는 미국, 브라질 등의 사례를 선별하여 소개한다. 이어서 생물다양성협약 체결 전후의 생물자원에 대한 인식 변화로 인해 국제적으로 합의한 나고야 의정서의 주요 핵심 내용을 발표한다. 그러나, 최근의 합성생물학은 유전정보만을 가지고 설계자의 의도대로 실물 생물자원 없이 새로운 생물과 원하는 물질을 합성할 수 있기에 국제적으로 마찰이 발생하고 있다. 유전공학과 합성생물학에서 가장 기본적으로 이용하고 있는 유전정보를 생물다양성협약에서는 어떻게 정의하고 있는지, 그리고 이익을 어떻게 공유하는지 알아본다. 생물자원 이용 국가들은 유전정보는 물리적인 실체가 없기에 이익공유대상이 아님을 주장하면서 유전정보는 원하는 누구에게나 이용되어야 한다고 보고 있다. 반면 생물자원 풍부국 입장은 생명과학기술 발전으로 인해 원산지 국가의 허가 없이 생물 유전정보를 활용하는 것은 생물 주권의 침해로 보고 있으며, 유전정보를 실물 생물자원과 동일하게 취급하여 나고야 의정서상의 이익공유를 요구하고 있다. 유전정보에 대한 대한민국의 공식적인 입장과 제 14차 협약 총회에서 합의한 결정문을 소개한다. 또한, 2019년 생물다양성과학기구(IPBES)에서 지구의 생물다양성과 생태계를 평가한 보고서에서 생물 멸종의 위협요인으로 제시된 토지이용 변화, 남획, 기후변화, 오염, 외래종에 대한 문제점을 기반으로 작성된 post-2020 생물다양성협약 10개년 실행 목표를 알아보고 2022년 12월 개최하는 제15차 당사국총회의 주요 의제에 대한 전망과 최근 문제가 되고 있는 '공동의 그러나 차별적인 책임(CBDR, Common But Differentiated Responsibility)'의 개념을 소개한다.

최근 이산화탄소(Carbon Dioxode, CO₂) 배출량 증가로 인하여 지구온난화와 같은 기후변화 문제가 심각한 사회 문제로 대두되고 있다. 이에 따라 2015년 12월 12일 프랑스 파리에서 열린 제21차 유엔기후변화협약에서 교토의정서를 대체하는 파리협정(Paris Agreement)을 채택하였으며, 국내에서는 이러한 국제사회의 기후변화 대응에 동참하고 온실가스 감축을 이행하기 위한 2050 탄소중립 정책을 추진하였다. 이산화탄소를 다량으로 발생시키는 철강·산업·건설·에너지 분야 중건설 분야에서 배출되는 이산화탄소는 전체 배출량의 19.9%로 특히 시멘트를 제조하는 과정에서 많은 양의 이산화탄소가 배출되고 있다. 기존의 건설 분야 에서는 이산화탄소를 저감하기 위해 콘크리트 배합 또는 양생과정에서 챔버 내 이산화탄소를 가스 형태로 주입하여 탄산화 반응을 통해 콘크리트 내부에 이산화탄소를 영구히 저장시키고자 하였다. 그러나 이는 챔버 사용, 양생조건 등 적용 조건이 제한적이며, 콘크리트 내 이산화탄소 흡수 효율이 높지 않아 이를 개선할 수 있는 기술이 필요하다. 이를 개선하기 위해 최근에는 콘크리트 배합수 내 이산화탄소를 용해시켜 배합과정에서 콘크리트 내부로 이산화탄소를 강제로 인입시키는 연구들이 진행되고 있다. 그러나 콘크리트 배합수로 사용되고 있는 일반물이나 지하수의 경우 가압을 하여도 약 1,400mg/L의 이산화탄소를 용해시키며, 가압을 통해 용해된 이산화탄소는 쉽게 대기 중으로 방출되는 한계점을 지니고 있어 현장에서 사용하기 어려운 문제가 있다. 이러한 한계점을 극복하기 위해서 본 연구에서는 200nm 이하의 크기를 가지는 나노버블기술을 이용해 압력을 가하지 않은 상태에서 수중에 이산화탄소를 용해시킬 수 있는 시스템을 개발하고자 한다. 나노버블기술을 이용한 수중 이산화탄소용해 시스템을 통해 수중에 이산화탄소를 용해시켜 콘크리트 배합수로 활용하기 위한 기초 연구가 될 것으로 판단된다.

To cope with various issues in the aspect of climate change adaptation of UNFCCC, Korea began preparing a Five-year National Climate Change Adaptation Plan in 2010 to be implemented from 2011~2015, for the purposes of securing a concrete system to adapt to climate change. Compared with the policies and measurement tools of developed countries, Korea's climate change adaptation capabilities suffers from a number of limitations including insufficiencies of basic information, human resources for research on climate change, and technology in risk and vulnerability assessment. At the same time, Korea maintains superior information technology systems, and comparatively strong climate change adaptation technologies. Recently, with the establishment of the Korea Adaptation Center for Climate Change as a specialized research organization in climate change adaptation, Korea has upgraded its ability to adapt to climate change and to provide support to other Asian countries which are vulnerable to climate change. In consideration of the close relation between climate change adaptation policy and technology development with the environmental industry, Korea's pursuit of cooperation and technical support for developing countries in the Asia region can be seen as the commencement of a long term investment for the nation's future. International cooperation on climate change adaptation between countries in the region can build a mutually complementary and integrated partnership in business, research, education, and other areas. Furthermore, Korea can also participate in the exploration of common issues as landmark projects that can attract global interest with developing countries.

As greenhouse gas (hereinafter GHGs) emissions have been increasing, the world's climate is also rapidly changed. $CO_2$ is the most important artificial GHGs and the annual emissions amount was increased approximately 80% between 1970 and 2004. After suggesting Kyoto Protocol, EU is the second largest emissions embodiment in the world, set the emissions trading scheme (hereinafter EU-ETS) and is trying to reduce $CO_2$ emissions aggressively. This study focuses on the EU-ETS and EU-ETS market to examine their emissions reduction policy and review the result of their efforts. EU-ETS which is composed of 2-step phases had already completed the first phase and is running on the second phase in 2008. Up to now EU-ETS has been proceeding successfully and the amount of $CO_2$ emissions has been decreased. To prepare for their coming events, countries excluded from Kyoto Protocol fulfillment need to have some implication from EU and have to make up their own plans.

Rapid accumulation of carbon dioxide in the atmosphere for the past century leads to acidify the surface ocean and contributes to the global warming as it forms acid in the ocean and it is a green house gas. In order to curb the green house gas emissions, in particular carbon dioxide, various multilateral agreements and programs have been established including UN Convention of Climate Change and its Kyoto Protocol for the last decades. Also a number of geo-engineering projects to manipulate the radiation balance of the earth have been proposed both from the science and industrial community worldwide. One of them is ocean fertilization to sequester carbon dioxide from the atmosphere through the photosynthesis of phytoplankton in the sea. Deliberate fertilization of the ocean with iron or nitrogen to large areas of the ocean has been proposed by commercial sector recently. Unfortunately the environmental consequences of the large scale ocean iron fertilization are not known and the current scientific information is still not sufcient to predict. In 2007, the joint meeting of parties of the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, 1972 and 1996 Protocol (London Convention/Protocol) has started considering the purposes and circumstances of proposed large-scale ocean iron fertilization operations and examined whether these activities are compatible with the aims of the Convention and Protocol and explore the need, and the potential mechanisms for regulation of such operations. The aim of this paper is to review the current development on the commercial ocean fertilization activities and management regimes in the potential ocean fertilization activities in the territorial sea, exclusive economic zone, and high seas, respectively, and further to have a view on the emerging international management regime to be London Convention/Protocol in conjunction with a support from the United Nations General Assembly through The United Nations Open-ended Informal Consultative Process on Oceans and the Law of the Sea.

In Climate change is a global issue that requires global responses. As a key factor in climate change, greenhouse gas (GHG) emissions have attracted increasing attention the international community. One of the crucial global efforts to alleviate climate change is the establishment of an international climate change regime, comprising rules, norms, principles, procedures that are applicable to a wide range of activities. The International Maritime Organization (IMO) received a mandate from the Kyoto Protocol to regulate shipping GHG emissions. However, the IMO Convention and the UN Convention on the Law of the Sea also provide regulations on regarding GHG emissions. To execute its mandate, the IMO has developed various regulatory initiatives. In addition, the Chinese government has declared new regulations which designate parts of its coastal waters as emission control areas (ECA). Owing to the growing recognition of the benefits of ECA, ships, including ocean-going vessels that operate in areas near the Pearl River Delta, Yangtze River Delta, and the Bohai Sea will be obliged to use fuel containing less than 0.5% sulfur. China's shipping industry is playing a growing role in the international shipping market, and its response to these initiatives will have a substantial effect on the future application of these regulations. This study analyzed the GHG mandates of the IMO and the Chinese government, and then examines the main outcomes that have been achieved.

With the worldwide trend of controlling the utilization fossil fuels inducing global climate change, many efforts will have to be made on securing stable supply of the energy due to UNFCCC. Tidal currents are a concentrated form of gravitational energy. Tidal current resource is significant, but limited locations. Technical and economic feasibility demonstration is the next needed step in the technology development process. So, we investigated overview of tidal in-stream energy in the sea near Wando, and then analytically estimated tidal energy resources and annual energy output of TECS arrays.

Climate change is one of the biggest dangers facing all living creatures in the earth. It has been understood that emissions of greenhouse gases from human activity is the cause of climate change. Cars are responsible for around 12% of total EU emissions of CO2, the main greenhouse gas. The United Nations Framework Convention on Climate Change (UNFCCC or FCCC) is an international environmental treaty adopted at the United Nations Conference on Environment and Development (UNCED) on 9 May, 1992, which entered into force on 21 March 1994. The European Commission first adopted a Community Strategy to reduce CO2 emissions from cars in 1995. On 19 December 2007, the European Commission proposed "Proposal for Setting emission performance standards for new passenger cars to reduce CO2 emissions", which was adopted on 23 April 2009 as "Regulation (EC) No 443/2009". Prior to submitting the Proposal, the European Commission performed impact assessment and prepared impact assessment report which was reviewed by the Impact Assessment Board. The objective of this Regulation is to set emission performance standards for new passenger cars registered in the Community, which forms part of the Community's integrated approach to reducing CO2 emissions from light-duty vehicles while ensuring the proper functioning of the internal market. In the event that a manufacturer fails to meet its target, it will be required to pay an excess emissions premium in respect of each calendar year from 2012 onwards. On 11 March 2014, Regulation (EC) No 333/2014 amending Regulation (EC) No 443/2009 was adopted. Regulation (EC) No 333/2014 amends Regulation (EC) No 443/2009 to implement the modalities of meeting the 95g CO2/km target for new passenger cars to be reached in 2020. As industry benefits from indications of the regulatory regime that would apply beyond 2020, the Regulation includes a further review to take place by, at the latest, 31 December 2014.

South Korea is the 8th biggest greenhouse gas emitter in the world due to its phenomenal economic growth based on manufacturing, and it is ranked first among OECD members for the rate of increase in emissions. Thus, the Korea government has voluntarily presented a reduction target and demonstrated global leadership. For the reduction of nation's GHG emission, importance of CCU(Carbon Capture and Utilization) along with CCS(Carbon Capture and Storage) technology development is increased. CCU technology is $CO_2$ utilization technology for the usage of $CO_2$ from flue gas and it can create a new economic value while reducing $CO_2$ emission. Therefore, with continued technology development, the number of application of CCU technology is increasing globally.
