Outline of Research at the Start

世界各国今後温室効果ガス(GHG)排出量の大幅な削減が求められる。本研究は2℃目標へ向かう低炭素社会と貧困の関係を定量的に明らかにすることを目的とする。それを実現するために、個別家計を対象にした調査データであるミクロデータから所得階層ごとの家計行動、具体的には家計所得、財・サービス別の家計消費を記述するモデルの開発を行い、所得階層別の低炭素政策の影響を解明し、低所得層向け政策を提案する。

Outline of Final Research Achievements

GHG emission reduction measures can have a significant impact on low-income and poor populations. Therefore, this study quantifies the relationship between a low-carbon society and poverty as we move toward the 2°C target. In this assignment, we show changes in the population and consumption and income of the poorest people who live on less than $1.90 a day. To achieve this, we developed a model that describes household behavior by income group, specifically household income and household consumption by goods and services, and elucidated the impact of low-carbon policies by income group, and proposed policies for low-income groups. Specifically, we examined the use of carbon tax revenue as a poverty measure, and showed that the potential for carbon tax revenue is large compared to the poverty gap.

Academic Significance and Societal Importance of the Research Achievements

本研究は脱炭素化という喫緊の環境問題の課題と途上国の貧困・開発という社会的な課題がどのように相互作用をもちうるのか、またその間でトレードオフがあれば、それに対してどのように対応するべきかという政策的な含意を得たもので、社会的な意義は非常に高い。また、学術的にも複数の社会経済属性を考慮した家計モデルを全世界180か国に渡って開発したという点で大きな意義があり、今後このモデルを拡張することで、貧困だけでなく、格差、エネルギー貧困、食料飢餓等をより現実性を持ってシミュレーションできるようになることが予想される。
