This article assesses Japan’s carbon budgets up to 2100 in the global efforts to achieve the 2 8C target under different effortsharing approaches based on long-term GHG mitigation scenarios published in 13 studies. The article also presents exemplary emission trajectories for Japan to stay within the calculated budget. The literature data allow for...

This study conducted a comparative assessment of 48 greenhouse gas (GHG) emissions reduction scenarios for 2030 reported in seven studies published since 2011 and based on bottom-up energy system analyses. This study conducted two sets of analyses. First, the scenarios were categorized into four mitigation effort levels and assessed the value...

＜要旨＞ 本稿では、現在公表されている18 GWにおよぶ石炭火力発電の新規建設及び更新（以下、設備追加）計画が日本の温暖化対策に関する中期目標（2030年目標）及び長期目標（2050年目標）に与える影響について分析した。加えて、これらの目標の達成に向けて電力業界全体の実効性のある取組が講じられた際の、石炭火力発電設備に対する経済的リスクについて考察した。 中期目標（2030年目標）の国際的評価と石炭火力発電の設備追加計画が与える影響 2015年4月30日に、日本政府は「2030年度に2013年度比26%削減（2005年度比25.4％削減）」とする約束草案要綱を発表し、長期エネルギー需給見通し骨子を了承した。本骨子では、「2030年の時点での電源構成として原子力発電を20～22%...

An up-to-date techno-economic assessment was conducted on CO2 emissions reduction potential in the Japanese iron and steel industry for 2030. The following mitigation measures were investigated: (i) maximized installation of best available technologies (BAT scenario), (ii) increased use of coke substitutes in blast furnaces, and (iii) increased use...

This research report has been prepared to provide an overview of the Japan 2050 Low Carbon Navigator (Low Carbon Navigator), how it works, and what its assumptions are. Section I introduces the Low Carbon Navigator to the audience, providing the background of the initiative as well as a description of the model. Section II explains the fundamental...
