本論文は、1999年から2023年までのカナダ州別データを用いて、所得不平等と炭素排出の関係を分析。上位20%の所得シェア増加は排出を増加させるが、その効果は非対称で、減少時の排出削減効果が大きい。下位80%の所得シェア増加は排出を減少させる。不平等是正が気候対策と両立することを示唆。
English
This paper analyzes the relationship between income inequality and carbon emissions using Canadian provincial data from 1999-2023. It finds that a higher income share for the top quintile increases emissions, with an asymmetric effect where decreases in share reduce emissions more than increases raise them. Higher shares for lower quintiles reduce emissions. Results suggest reducing inequality can aid climate mitigation.

日本のGX文脈において
日本のGX政策では、炭素税や排出量取引の公平性が議論されるが、本論文は所得分配と排出の因果関係を実証。日本の所得格差と排出構造の分析に応用可能な手法を提供する。
In the global GX context
This paper contributes to the global debate on climate justice and just transition by providing empirical evidence that reducing inequality can support emissions reduction. It challenges the notion of a trade-off between equity and climate action, relevant for international policy frameworks like the Paris Agreement.
👥 読者別の含意
🔬研究者:Provides empirical methodology for analyzing income distribution and emissions, with asymmetric effects that merit further study.
🏢実務担当者:Offers evidence that corporate sustainability strategies addressing inequality (e.g., fair wages) can also reduce carbon footprint.
🏛政策担当者:Supports policies that reduce top income shares (e.g., progressive taxation) as part of climate mitigation strategy.
📄 Abstract（原文）
The authors conduct a comprehensive analysis of the relationship between carbon emissions and multiple characteristics of income inequality for the Canadian provinces for the 1999 to 2023 period. Particular attention is given to how disposable income shares for different groups affect province-level emissions. The analysis yields multiple findings of substantive relevance. First, the income share of the top quintile has a nontrivial positive effect on emissions in both the short-run and the long-run. This effect is found to be statistically asymmetrical, where a unit decrease in the income share has a proportionally larger effect on decreasing emissions than a unit increase does in increasing carbon emissions. Second, greater shares of disposable income going towards groups below the top quintile have negative short-run and long-run effects on carbon emissions, and these effects are statistically symmetrical. Finally, the effects of all income share measures are statistically equivalent for emissions from different sectors, robust to various model specifications, and not sensitive to the inclusion of different economic and demographic controls. Overall, the results highlight the climate mitigation potential of reducing income inequality in particular ways, and calls into question analytical arguments suggesting that addressing inequality is antithetical to solving the climate crisis. • Effects of income inequality characteristics on CO2 emissions are modeled • Focus is on CO2 emissions and inequality for Canada's provinces • Disposable income share of top quintile positively affects emissions • Disposable income shares of bottom four quintiles negatively affect emissions
