A Research on the Policies for reducing greenhouse gasses-----Incentive Measures for Construction Sector

本研究考察了减少建筑行业温室气体排放的政策工具。虽然政府有多种减少温室气体排放的政策选择，但每种政策手段都有自己的优缺点。重要的是，政府在制定政策计划之前应该做出最好的选择。经济学文献包含了对减少温室气体排放的成本或收益的估计。决策者应该整合来自许多来源的信息，并在一系列研究和方法的基础上形成一种综合，每一种研究和方法都提供了对问题某些方面的见解，而忽略了其他方面。建筑行业在日本经济上占有重要地位，在工业活动和就业中占很大比例。建筑行业对环境也有很大影响。在日本，经营性建筑能耗约占最终能耗的25%-40%。例如，建筑法规长期以来一直在提高能源效率方面发挥着核心作用。如果经济手段和信息工具在建筑部门得到适当的结合，它们可以相互提高效率。

This research examined policy instruments for reducing greenhouse gasses form building sector. Though government has various policy options for reducing green house gases, each policy means has its own merits and demerits. It is important that government makes should do the best choice before the policy plan.The economics literature contains estimates of the costs or benefits reducing greenhouse gases. Policymakers should integrate information from many sources and develop a synthesis based on a range of studies and approaches, each of which provides insight into some aspects of the problem while ignoring others.The building sector is economically important in Japan, accounting for a significant proportion of industrial activites and jobs The building sector also has a great impact on the environment. The energy consumed in operating buildings accounts for about 25%-40% of final energy consumption in Japan. Building regulations, for example, have long played a central role in improving energy efficiency. Economic instrument and information tools could enhance each other's effectiveness if they were appropriately combined for building sectors.
