再生可能エネルギーの拡大が廃棄物部門のメタン排出強度低下と関連するかを、世界の国年パネルデータで分析。収入レベルや統治の質によって関連性が異なり、持続可能なメタン削減には再生可能エネルギー転換と廃棄物システム近代化の連携したガバナンスが必要であることを示す。
English
This global panel study examines whether renewable electricity expansion is associated with lower waste sector methane intensity. It finds a consistent negative association that strengthens with income and governance quality, suggesting that sustainable methane mitigation requires coordinated governance linking renewable transition and waste system modernization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策では、再生可能エネルギー導入と廃棄物管理の連携はまだ十分に議論されていない。本稿は、廃棄物部門のメタン排出削減には、エネルギー転換単独ではなく、ガバナンス条件付きの政策連携が重要であることを示唆。
In the global GX context
This paper provides global evidence that renewable electricity expansion alone is insufficient for methane mitigation; governance quality and waste system modernization are critical. It informs global discussions on integrated climate policies beyond power sector decarbonization.
👥 読者別の含意
🔬研究者:Empirical evidence on cross-sectoral co-benefits of renewable transition for researchers studying climate policy integration.
🏢実務担当者:Corporate sustainability teams can consider cross-sectoral impacts of renewable energy procurement on waste-related emissions.
🏛政策担当者:Regulators should design coordinated policies linking renewable energy and waste management governance structures.
📄 Abstract（原文）
Achieving sustainability requires that energy transition generates measurable environmental benefits beyond the power sector, yet it remains unclear whether renewable electricity expansion is associated with lower waste sector methane intensity, a major source of short-lived climate forcing. Using a global country–year panel and two-way fixed effects, we examine whether this relationship, and its sustainability implications, varies with development stage, institutional quality, and waste system characteristics. We find no robust inverted-U Environmental Kuznets Curve once country and year fixed effects are included. Instead, higher renewable electricity shares are consistently associated with lower waste sector methane intensity, and this association strengthens with income. A 10-percentage-point increase in renewable share corresponds to about 2.7%, 4.2%, and 6.0% lower intensity at the 25th, 50th, and 75th income percentiles. The negative association is stronger in countries with higher governance quality, while waste management capacity and organic waste composition reveal additional heterogeneity in the observed association. Overall, electricity decarbonization alone is not a uniform instrument for reducing diffuse biological emissions; sustainable methane mitigation likely requires coordinated governance linking renewable transition with waste system modernization.
