Discussion Paper
Our lifestyles, through the impacts of our day-to-day activities such as eating, moving and commuting, heating and cooling our homes, caring, working, and so on, have become major threats to the sustainability of the environment. While continued economic growth and urbanisation in many countries are expected, it is imperative to consider how we...

Analysing sustainable pathways and carbon reduction trajectories based on SSPs in Los Angeles to achieve a carbon neutral andsustainable city (Phase 1: SSP narratives)

Author:
Under the Paris Agreement, which was adopted in 2015, Los Angeles has been strongly motivated to be a global leader by creating an achievable climate action plan and sustainable solutions. To meet its goals, the city has developed L.A.’ s Green New Deal, which is an expanded version of the first Sustainable City pLAn developed in 2015. This Green...

With the advent of high-spatial resolution (HSR) satellite imagery, urban land use/land cover (LULC) mapping has become one of the most popular applications in remote sensing. Due to the importance of context information (e.g., size/shape/texture) for classifying urban LULC features, Geographic Object-Based Image Analysis (GEOBIA) techniques are...

平成29年度パリ協定の実施に向けた 詳細ルールの検討・情報整理等業務

本報告書は、環境省委託事業「平成29年度パリ協定の実施に向けた詳細ルールの検討・情報整理等業務」に関する成果をまとめたものである。
Commissioned Report
途上国の森林減少・劣化に由来する温室効果ガス排出の削減等(以下「REDD+」という。)は重要な気候変動対策であり、気候変動に関する国際連合枠組条約の第21回締約国会議(COP21)で合意された「パリ協定」にもその実施と支援を奨励することが明記されたところである。 REDD+の推進には、途上国に対する資金と技術の提供が必要とされているが、公的資金には限界があることから、今後、REDD+の取組みを拡大していくには、民間セクターからの資金や技術の提供が鍵となる。しかしながら、民間セクターがREDD+に対して投資するには、排出削減クレジットが獲得できる等のインセンティブが必要(①)とされる。また、途上国がREDD+を実施するには、COP決定を踏まえつつ、各々の国情に応じた排出削減量の算定...

Discussion Paper
2014年11月12日、米中首脳会談後の共同声明において、米国と中国が、以下のような温室効果ガス(GHG)の排出削減目標を発表した。 o 米国:2025年までにGHG排出量を2005年比で26~28%削減 o 中国:2030年頃までに、なるべく早い時期にCO2排出量を頭打ち(ピークアウト); 一次エネルギー消費における非化石燃料の割合を2030年までに約20%  本稿では、米中の2020年以降の温暖化対策目標について、既存文献で示される両国の排出経路シナリオと比較することにより、目標の野心度についての評価を行った。評価するに当たり、気温上昇2℃未満抑制に向けた排出経路との整合性、及び目標達成のための追加的な努力の必要性、という二つの評価軸を用いた。前者は環境十全性の視点から評価であり...
