오늘날 지구온난화현상이 심각한 환경문제로 대두되어, 1988년 IPCC 발족, 1994년 '기후변화협약' 발효를 통해 온실가스 배출을 저감하고 기후변화에 공동 대응을 모색하기 위한 범지구적 노력을 기울이고 있다. 우리나라도 2020년까지 온실가스 배출량을 감축목표를 BAU(business as usual:온실가스 감축을 위한 행동을 하지 않았을 때의 자연적인 배출변화량) 대비 30%로 결정한 바 있으며, 농업부문도 온실가스 감축기술을 개발하여 농업 현장에 널리 보급할 필요가 있다. 농업부분 온실가스 배출량은 1,840만 $CO_2$톤(2007)으로 산정되어 국가 전체 발생량의 2.9%에 해당한다. 이 중 경종부분이 65%, 축산부분이 35%인데, 경종부분 온실가스의 대부분은 벼농사가 차지하므로 벼농사에 있어서 온실가스 감축이 시급한 것으로 나타났다.

Cap-and-trade policies that allow firms to trade emission allowances are designed to reduce emissions at least cost and are shown to be efficient when there is no uncertainty over emissions. This paper examines how uncertainty in emissions affects firms' decisions about permit purchase and abatement. The results show that whether firms abate more under uncertainty compared to a case with no uncertainty depends on the expected penalty cost and marginal abatement cost. If the expected marginal penalty cost is greater than the marginal abatement cost, the firm will choose to reduce emissions and abate more under uncertainty. When the expected marginal penalty is greater than the marginal cost of abatement, increases in uncertainty result in reduced emissions. This paper also examines whether the order of abatement and permit trading and the realization of uncertainty affect firms' decisions. The results show that total expected emissions are the same regardless of the order of moves.

Reducing emissions across all sectors requires a well-designed policies tailored to fit specific national circumstances. And every climate policymaker would like to have an accurate method of assessing the quantitative impacts of future policies to address GHG-related problems. Estimates of future changes in a nation's GHG emissions, the expected environmental impacts of future energy sector developments, and the potential costs and benefits of different climate technology and mitigation policy options are desirable inputs to policy making. Various mitigation analysis and modeling approaches helped to fill the needs for these kinds of information, and as such has been an important part of national mitigation policy making in many countries for most of two decades. This paper provides a overview of GHG mitigation policies and mitigation analysis, and sectoral mitigation circumstances and potentials.

The objective of this study was to assess the feasibility of a landfill project aimed at reducing greenhouse gas (GHG) from Puerto Cortes Landfill in Honduras ("Project"). The feasibility study involved surveying the status, composition and amount of waste entering the landfill, and projecting GHG emissions from the landfill. A projection of the GHG emissions with the IPCC model and based on the survey results indicated that the period 2027 to 2041 would see a total GHG emission reduction of 506,835 ton-CO₂/year, with a mean yearly GHG emission reduction of 33,789 ton-CO₂, assuming landfill gas collection is implemented, The findings of the study are expected to serve as basic data for deciding about whether and how to proceed with the Project.

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.

교토의정서(Kyoto Protocol) 기후변화협약에 따른 온실가스 감축에 관한 의정서. 1997년 교토에서 열린 유엔기후변화협약 당사국 총회에서 채택. 선진국은 2008~2012년 사이에 온실가스 배출량을 1990년 배출량 대비 평균 5.2% 감축토록 규정. 한국은 의무감축 대상국이 아니며 미국은 교토의정서를 비준하지 않았음.

Although market stabilization measures have been triggered in the K-ETS, carbon price is still under uncertainty. Considering Korea's 2030 enhanced reduction target announced in October 2021, it is crucial to have practical stabilization measures to appropriately deal with price uncertainty. This study examines the quantitative effects of a price collar, which is considered as a means of alleviating price uncertainty, on expected cumulative emissions and abatement costs. There are three main scenarios: carbon tax, emissions trading system, and emissions trading system with a price collar. Monte Carlo simulation was conducted to reflect uncertainty in emission. There are several results as follows: 1) In a price collar, domestic emission target is likely to be achieved with a lower expected abatement cost than other scenarios. In addition, there is a small amount of excess emissions in this research and it would be not critical(0.1% excess than target); 2) Prohibiting banking increases the expected abatement cost. This is because firms can not intertemporally reallocate allowances to match the firm's optimal emissions path; 3) With the adoption of a price collar, government's net revenue can be positive even if the government's purchase volume of emissions allowances is more than sales volume. This is because the government sells them at price ceiling and purchases them at price floor.

A bottom-up approach has been conducted to estimate greenhouse gas (GHG) emission and to analyze the marginal abatement cost for the Korean horticulture energy sector. With the systematically derived activity and energy balance data, the BAUs have been estimated, along with the marginal abatement cost over the period 2010 through 2030. The result from the marginal abatement cost analysis may provide general guidelines and procedures for the establishment of GHG abatement polices.
