The impact of carbon emissions trading scheme on residents’ medical expenses: a test based on multi-period difference-in-differences method

日本語

本研究は、炭素排出権取引制度（ETS）が住民の医療費に与える影響を、複数時点差分の差法（多期間DID）を用いて実証分析した。ETS導入地域では医療費が統計的に有意に減少することを示唆し、炭素価格政策が環境改善を通じて公衆衛生面でも便益をもたらす可能性を提示している。

English

This study empirically examines the impact of carbon emissions trading schemes (ETS) on residents' medical expenses using a multi-period difference-in-differences approach. The findings suggest that ETS implementation significantly reduces medical expenses, indicating potential public health co-benefits of carbon pricing policies through improved environmental quality.

日本のGX文脈において

日本でもGXリーグによるカーボンプライシング導入が進む中、本論文は炭素価格が医療費削減という副次的便益をもたらす可能性を示す。日本の健康政策と気候政策の連携を検討する際のエビデンスとなり得る。

In the global GX context

As carbon pricing gains traction globally (e.g., EU ETS, China's national ETS), this study adds evidence on health co-benefits, which is often overlooked in cost-benefit analyses. It supports integrating health impact assessments into carbon pricing design, relevant for policymakers considering climate and health synergies.
