The purpose of this study is to establish a methodology for evaluating quantitative effects of transportation GHG (greenhouse gas) reduction-related policies that were implemented based on the reduction goals of transportation GHG and effective implementation plans. This study uses a modal utility function and demand estimation models as well as a GHG emission basic unit estimation model by each transportation mode based on actual traffic and emission data. The results showed that the effects of GHG reduction policies such as electric vary from region to region, and from vehicle to vehicle. It is also confirmed that an eco-drive promotion policy, one of the lowest budget policies, is expected to contribute to high reduction in GHG. In addition, not only automobile emission improvement policies but also the promotion policies of public transportation are expected to highly reduce GHG as confirmed quantitatively in this study. The results of this study are expected to be useful for national and local governments' evaluation of GHG reduction policies to cope with the post 2020.

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.

Korean Government announced 'The Roadmap to realize a low carbon green society on year 2020' on July 12, 2011 in order to mitigate greenhouse gas (GHG) emissions. Non-energy category of Food, Agriculture, Forestry and Fishery (FAFF) should mitigate 1,349 kilo $CO_2$-equivalent ($CO_2$-eq.) tonnes which is 7.1% of Business-As-Usual on year 2020. The mitigation from animal manure treatment system (AMTS) comprises ca. 45% of the total mitigated amount of Non-energy category of FAFF. Hence, the precise evaluation of GHG emissions from AMTS is important to find effective mitigation measures. Life cycle assessment was used to evaluate GHG emissions from AMTS. The most GHG emitter was a composting/liquid fertilizer/activated sludge system (1,649.45 kg $CO_2$-eq./head/year) and the least GHG emitter was a activated liquid fertilizer system (1,024.46 kg $CO_2$-eq./head/year). Thermophilic oxic process showed the highest ratio (34.9%) of GHG emissions by the use of electricity to total GHG emissions from systems. Energy efficiency should be considered to mitigate GHG emissions from AMTS.

Greenhouse gases (GHGs) emissions from Kangwon National University was estimated to be 21,054 ton $CO_2$-eq in 2009, which was approximately 7% higher than that in 2005. Emissions from electricity usage in Scope 2 contributed to the upward annual trend of GHG emissions, comprising about 54.3% of the total GHG emissions. On the other hand, GHG emissions from Scope 1 and Scope 3 contributed approximately 25.3% and 20.4%, respectively. Various GHG reduction plans were also introduced and evaluated in this study. Among three reduction plans including LED substitution, improvement of transportation efficiency, and green campus action plan, the green campus action plan derived the most significant GHG reduction of 5.3% of total emissions. Estimated total reduced GHG emission was $1,570ton\;CO_2-eq\;yr^{-1}$ with all three reduction plans.

This study was conducted to estimate the greenhouse gas emissions on local government levels from 1990 to 2010 using 2006 IPCC guideline methodology. To calculate greenhouse gas emissions based on the 16 local governments, emission factor and scaling factor were used with default value and activity data came from the food, agricultural, forestry and fisheries statistical yearbook of MIFAFF (Ministry for Food, Agriculture, Forestry, and Fisheries). The total emissions in crop sector gradually decreased from 1990 to 2010 due to a decline in agricultural land and nitrogen fertilizer usage. The annual average emission of greenhouse gas was the highest in Jeonnam (JN) with 1,698 Gg $CO_2$-eq and following Chungnam (CN), Gyungbuk (GB), Jeonbuk (JB) and Gyunggi (GG). The sum of top-six locals emission had occupied 83.4% of the total emission in cropland sector. The annual average emissions in 1990 by applying 2006 IPCC guideline were approximately 43% less than the national greenhouse gas inventory by 1996 IPCC guideline. Jeonnam (JN) province occupied also the highest results of greenhouse gas emission estimated by gas types (methane, nitrous oxide and carbon dioxide) and emission sources such as rice cultivation, agricultural soil, field burning of crop residue and urea fertilizer.

Recently the number of motorcycles has increased in urban area, and it is believed that motorcycle is one of the air pollution and greenhouse gas emission sources. But the greenhouse gas emission from motorcycle has been high uncertainty due investigation of a lack of activity data and emission factors in Korea. So in this study, the greenhouse gas emission from motorcycle is estimated by considering the population of moped and VKT(vehicle kilometers travelled) of motorcycle by recent other studies. And the emissions by IPCC Tier 2 and Tier 3 methodology are calculated and compared. As the results, the nationwide $CO_2$ equivalent emissions from motorcycles by Tier 2 and Tier 3 method are calculated as 2,758 kton/yr and 2,739 kton/yr in 2008. The contribution ratio of this emission is estimated as 2.7% in on-road transport sector.

This study aims to introduce greenhouse gas emission trading in Korea as a highly cost-effective mechanism for controlling emissions. The Basic Act on Low-Carbon Green Growth will cover methods of emissions allocation, national inventory, and trading systems (i.e. emissions trading platforms, national registry,and clearing and settlement platforms). The Korean emission scheme will be based on the Korean Climate Change Act proposed by the National Assembly and Government with a cap-and-trade scheme. The national allowances will be allocated by the hybrid system. To establish the national inventory, TRADEMARKS (Telemetering System) and emissions factors are effective for greenhouse gas emissions measurement. It will likewise be effective for the national registry to be implemented via a Korean Integrated Registry, the emissions trading platform via the KRX (Korean Exchange), and the clearing and settlement platform via the KSD (Korean Securities Depository). In other words, the KRX will manage product development and marketing for Korean Carbon Financial Instruments (including commodities, futures, and options contracts) listed and admitted to trading on the KRX. All emissions trades will be standardized and cleared by the KSD.

In this study, the anthracite coal being used as fuel in Korea were classified into different types. These types include the domestically produced anthracite, imported anthracite used as raw material, and imported anthracite used as fuel. Each of the calorific values and greenhouse gas emission factors were calculated. The calculation of greenhouse gas emission factors resulted in the domestically produced anthracite as $111,477{\pm}4,508kg\;CO_2/TJ$, the imported anthracite used as raw material as $108,358{\pm}4,033kg\;CO_2/TJ$, and anthracite used as fuel was displayed as $103,927{\pm}8,367kg\;CO_2/TJ$. Additionally, the amount of greenhouse gas emission based on these calculated emission factors was displayed as $6,216,942ton\;CO_2$, which resulted as 12.7% lower than the green house gas emission amount which was calculated without distinguishing anthracite coal in details. Therefore, collecting activity data through a detailed classification of anthracites facilitate a more accurate calculation of greenhouse gas emission amount compared to collecting activity data through combination. Furthermore, since the anthracite coal used domestically possesses characteristics differing from the anthracite coal proposed by the IPCC, anthracite coal should be classified for each purpose and calculated for the improvement of the national greenhouse gas inventory.

온실가스 감축 의무를 규정한 쿄토의정서의 발효 여부를 결정지을 기후변화협약 제9차 당사국회의(cop9)가 12월 1일부터 12일까지 이탈리아 밀라노에서 개최되고 있다. 기후변화협약은 지구온난화 현상과 기상이변을 일으키는 온실가스를 지난 1990년 수준에서 더 이상 늘리지 않기로 한 국제협약이다. 기후변화협약은 지난 1992년 6월 '리우환경회의'에서 채택돼 각국 비준을 거쳐 1994년부터 발효됐다. 하지만 기후변화협약은 강제성이 없어서 어느 나라도 이산화탄소를 줄이는 조치를 적극적으로 취하지 않았다. 이러한 문제점을 해결하기 위하여 1997년에 마련된 '쿄토의정서'가 채택되었다. 이에 의하면 선진 38개국들은 2008~2012년 사이에 1990년 발생량보다 평균 5.2%를 더 줄이기로 합의하고 세계 온실가스 배출량의 55%의 비준을 의정서 발효조건으로 규정하였다. 그러나 이산화탄소 최대 배출국인 미국이 2001년에 탈퇴를 선언하고, 배출량의 17.4%를 차지하는 러시아도 최근 비준 거부의사를 밝히고 있어 쿄토의정서의 발효는 사실상 어려워진 상태이다. 쿄토의정서가 발효되지 않고 폐기되더라도 기후변화 협약은 유효하기 때문에 새로운 의정서 논의가 제기될 전망이며, 세계 9위의 온실가스 배출국인 우리나라에 대한 온실가스 감축의무 부담요구는 가중될 전망이다. 다시 관심의 초점으로 떠오르는 기후변화협약에 대한 이해를 돕기 위해 산업자원부가 발표한 자료를 게재 하였다.<편집자 주>

정부는 2013년부터 온실가스 배출권거래제도를 시행하기로 하였다가 일부 산업계의 반대에 부딪쳐서 2015년으로 그 시행시기를 늦춘 바가 있다. 그나마 2015년에 시행하기로 한 배출권거래제도도 국회에서 처리가 지연되어 법률화되지 못하고 있다. 배출권거래제도와 관련하여서 여러 논란이 있으나, 이러한 논의들 중에는 부정확한 개념과 지식에 기반을 두고 있는 경우가 많다. 이제는 배출권거래제도에 대해 올바르게 이해하여 정부 정책이 잘 수행될 수 있도록 노력하여야 할 시기가 되었다.
