OECD36カ国・1980〜2018年のパネルデータを用い、観光需要・再エネ消費・環境税が炭素排出に与える影響をベイズモデル平均化とWALSで分析。観光拡大は排出を増やす一方、環境税単独では効果が不安定だが、観光と環境税の交互作用は排出抑制に寄与する。環境税は高所得国で有効、高中所得国では非有意。再エネは一貫して排出削減に貢献する。
English
Using 1980–2018 panel data for 36 OECD countries, this study applies Bayesian Model Averaging and Weighted-Average Least Squares to assess how tourism demand, renewable energy, and environmental taxes affect carbon emissions. Tourism raises emissions, environmental taxes alone are inconsistent, but tourism–tax interaction mitigates emissions. Taxes work in high-income economies but not upper-middle-income ones; renewables consistently cut emissions.

日本のGX文脈において
炭素税・環境税の実効性と所得水準依存性を示す知見は、日本でのカーボンプライシング設計やGX推進における税制・排出量取引の議論に示唆を与える。観光立国政策と脱炭素の両立という論点も日本文脈に接続する。
In the global GX context
The finding that environmental taxes reduce emissions mainly in high-income economies and only when paired with tourism activity speaks to global carbon-pricing design debates under TCFD/ISSB transition planning and the EU's evolving carbon policy mix.

📄 Abstract（原文）
The effectiveness of environmental taxation and renewable energy deployment in mitigating carbon emissions remains a central concern in energy and sustainability policy. This study examines how tourism-driven energy demand interacts with green energy consumption and environmental taxation to influence carbon emissions across 36 OECD countries from 1980 to 2018. Using Bayesian Model Averaging and Weighted-Average Least Squares, the analysis explicitly addresses model uncertainty in long-run energy–environment relationships. The results indicate that tourism expansion significantly increases carbon emissions, reflecting its energy-intensive nature. Environmental taxes, when considered in isolation, do not consistently reduce emissions across OECD countries, largely because of tax exemptions and uneven enforcement. However, the interaction between tourism activity and environmental taxation reveals that well-designed fiscal instruments can mitigate tourism-induced emissions. Moreover, environmental taxes are found to be effective in reducing emissions in high-income OECD economies, while their impact remains insignificant in upper-middle-income countries. Renewable energy consumption consistently contributes to emission reductions. These findings underscore the importance of integrating environmental taxation with energy-transition policies and renewable energy investment. The study provides policy-relevant insights for designing effective carbon mitigation strategies that align fiscal instruments with long-term sustainability and energy-transition objectives.
