In this study, the concentrations of offensive odorous compounds seasonally emitted from the chemical plant at Chongju industrial complex in Korea were determined by the analytical methods of gas chromatography, high performance liquid chromatography and uv/vis spectroscopy. The kinds of offensive odorous compounds examined are formaldehyde, acetaldehyde, butyl aldehyde, propion aldehyde, n-valeric aldehyde, iso-valeric aldehyde, hydrogen sulfide, methyl mercaptan, dimethyl sulfide, dimethyl disulfide, trimethyl amine and ammonia. The seasonally emission levels of all odorous compounds except dimethyl sulfide at 13 sampling points of plant were lower than those of the regulation standard levels of the industrial complex in Korea. The levels were the highest in June, and lowest in December. The propion aldehyde and iso-valeric aldehyde in June and December, butyl aldehyde in December, and n-valeric aldehyde were not detected in all the three seasons at any sampling points of the plant examined. But in June, dimethyl sulfide was emitted up to 16 times than that of the regulation level.

California's heartland, the Great Central Valley, is one of the most productive agricultural regions in the world. However for many years the valley has been struggling with a broad range of social, economic, and environmental challenges. Some significant concerns include water resources, air pollution, poverty rates, housing issues, etc. Another strike against the valley is the relative reluctance to embrace widespread sustainable building practices. This paper discusses the long-term and profound impact of the built environment has on the aforementioned socioeconomic and environmental issues facing the valley. It reviews exemplary practices in other states and regions regarding policy-making and regulation in the building industry as well as sustainable community development. The paper further explores viable options specifically for the Fresno metropolitan area (the largest in the Central Valley) to combat its unique multifaceted challenges.

Objectives Despite the great contribution made by chemical substances to the development of modern civilization, their indiscriminate use has caused various kinds of damage to the global environment and human beings. Accordingly, the major developed countries and international society have tried to ensure the safe use of chemicals and a reduction in the use of hazardous chemicals through the establishment of the United Nations Environment Programme and various international agreements. In this reason, we tried to introduce about Green Chemistry progress at the present in worldwide and Korea. Methods We checked and analyzed relative journals, reports using keyword as like Green Chemistry, alternative chemicals, eco-friendly etc. and major country's government homepage search. Results Green Chemistry theory, which argues for the reduction or removal of harmfulness in chemicals throughout their entire life-cycle, has been spreading, and major developed countries, such as the US and Denmark, have developed and operate programs to provide reliable chemical information to help replace hazardous chemicals. Korea has also been conducting studies as like eco-innovation project. Through this project the "Alternative Chemical Search program," has been developed, distributed, and operated since 2011 to provide reliable information to small and medium-sized businesses that have difficulties collecting information to ensure conformity to international regulations. The program provides information that includes the regulations of major countries and Korea, information on 340 alternative chemicals, 70 application cases, and 1:1 consulting. Conclusions The Alternative Chemical Search program is expected to contribute to the establishment of response systems for regulation of Korean small and medium-sized businesses, and it also will be used to provide basic data for Korean hazardous chemical regulation, together with the Act on the Registration and Evaluation, etc. of Chemical Substances and the Chemical Control act, making it possible to establish an infrastructure for Green Chemistry in Korea and to increase national competitiveness.

본 연구는 FTA의 효과를 극대화하는 데 있어, 무역자유화의 이익을 침해하지 않으며, 동시에 환경보호를 달성하기 위한 환경규정의 제정방향에 대하여 연구하였다. 본 연구를 통하여 FTA체제하에서의 무역자유화와 환경보호 달성을 위한 환경규정의 제정방향은 크게 세 가지로 요약해 볼 수 있다. 첫째는 FTA협정문상의 환경기준을 적용하는 데 있어서는 새로운 환경기준을 적용하기 보다는 기존의 있는 환경기준을 적용하여 환경협상력을 강화하고 교묘하게 운영되는 환경보호조치를 축소하기 위한 노력을 기울여야 한다. 둘째로 FTA 체결국간에 논란의 여지가 많은 것에 대해서는 보다 엄격한 환경관련 규정을 적용하거나 현행 WTO규정 및 다자간환경협약을 그대로 적용하는 것이 타당할 것으로 보여진다. 셋째는 FTA를 통한 환경기술이나 제품에 대한 적극적인 교류를 확대할 수 있는 규범 제정이 필요하다. 마지막으로 환경과 관련한 실체적 규범과 절차적 규범에 대한 명확한 제정이 이루어져서 오염행위나 환경마찰에 대하여 신속하고 객관적인 이행이 보장되도록 해야 한다.

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.

세계적으로 기후변화에 대응하기 위한 탄소배출 규제가 강화됨에 따라 한국도 기후변화협약의 당사국으로서 강력한 이행을 권고 받고 있다. 특히 한국은 환경규제 강화에 대한 정부와 산업계, 국민의 이해관계가 복잡한 만큼 환경규제가 경제성장과 전력소비량, 이산화탄소 배출량 감축에 어떠한 영향을 미치는지에 관한 연구는 매우 중요하다. 이에 본 논문은 한국에 있어 환경규제와 경제성장, 전력소비량, 이산화탄소 배출량에 관한 인과관계를 실증분석하였다. 이를 위해 1987 ~ 2014년 동안의 시계열 자료를 바탕으로 단위근 검정, 공적분 검정, 벡터오차수정모형(VECM)을 통한 인과성 검정을 실시하였다. 분석의 결과, 환경규제는 전력소비량과 이산화탄소 배출량 간 양방향의 장기 및 강인과관계를 가지며, 전력소비량과 단기적으로 영향을 받는 반면, 경제성장에는 영향을 미치지 못하면서 일방적으로 장기 및 강인과관계로 영향을 받는 것으로 분석되었다. 경제성장은 장기적으로 전력소비량, 이산화탄소 배출량, 환경규제에 영향을 미치면서 단기적으로 전력소비량에 단방향의 인과관계를 보였고, 이산화탄소 배출량은 양방향의 인과관계를 갖는 것으로 나타났다. 이러한 분석결과에 대응할 수 있는 정책적 시사점으로는, 환경규제가 이산화탄소 배출량 감축을 위한 기술혁신과 생산성 향상을 유발하여 경제성장에 기여할 수 있도록 하는 정책개발이 필요하다. 또한 국제 탄소배출 규제가 본격적으로 실행될 경우, 환경규제가 혁신을 통한 경제성장, 전력소비량에 따른 전원구성의 변화와 이산화탄소 배출량의 감축 등에 관련된 정책 간에 충돌을 일으키지 않고 시너지 효과를 창출하도록 하는 세심한 정책구상이 필요하다.

The ship recycling or scrap is a phenomenon in the process of vessels life cycle has ended in the shipping industry. Scrap are greatly affected by freight rates due to ship demands. Not only that, environmental regulation and economic scale vessel demand are processes that must exist in the shipping industry as they obtain management for existing vessels. In the past, shipbreaking yard had tried to work without protection for poverty, without poor working conditions and facilities to prevent the emission of harmful substances. However, the issue of environmental pollution has been raised the Basel and Hong Kong Convention have been adopted, and a new replacement of the ship scrap that induces serious pollution is required. In this study, 165 countries were analyzed to confirm the importance of determining the ship solution. As a result of the analysis, it was found that the Environmental Performance Index, which is a measure of environmental regulation, is the most influential factor of ship scrapped volume. The determinant of whether lower labor cost can be secured is more correlated with population than GDP per capita. The implications of the results of the regression analysis mean that if environmental regulations for ship scrap of the future are strengthened, the status of Bangladesh and Pakistan, which currently account for half of the world's ship recycling, may change.

Recently IPCC (International Panel on Climate Change, 2007) pointed out that global warming is a certain ongoing process on the earth, due to which water resources management is becoming one of the most difficult tasks with the frequent occurrences of extreme floods and droughts. In this study we made runoff predictions for several control points in the Geum River by using the watershed runoff model, SSARR (Streamflow Synthesis and Reservoir Regulation Model), with daily RCP 4.5 and RCP 8.5 scenarios for 100 year from 1st Jan 2006 to 31st Dec 2100 at the resolution of 1 km given by Climate Change Information Center. As a result of, the Geum River Basin is predicted to be a constant flow increases, and it showed a variation in the water circulation system. Thus, it was found that the different seasonality occurred.
