日本語

本論文は、1993～2021年のBRICS諸国を対象に、植林、エネルギー生産性、再生可能エネルギー発電、原子力発電がCO2排出に与える短期的・長期的影響を、ブートストラップ共和分・因果性検定を用いて分析した。結果、長期的には植林、エネルギー生産性、再生可能エネルギーはほとんどの国で排出削減に寄与するが、原子力は中国とロシアのみで効果があることが示された。短期的効果は限定的であり、これらの施策の長期的推進が重要と結論づけている。

English

This paper analyzes the short- and long-term effects of afforestation, energy productivity, renewable electricity generation, and nuclear electricity generation on CO2 emissions in BRICS countries from 1993 to 2021 using bootstrap cointegration and causality tests. Findings show that in the long run, afforestation, energy productivity, and renewables reduce emissions in most BRICS countries, while nuclear only benefits China and Russia. Short-term effects are weaker, suggesting that promoting these factors is crucial for long-term decarbonization.

日本のGX文脈において

日本はBRICS諸国ではないが、本分析は森林再生、エネルギー生産性向上、再生可能エネルギー導入といった施策がCO2削減に有効であることを示唆している。日本の森林経営やエネルギー効率政策への間接的な示唆を与えるとともに、新興国との国際協力においても参考となる実証的根拠を提供する。

In the global GX context

This study provides robust empirical evidence on the effectiveness of afforestation, energy productivity, renewables, and nuclear power for reducing CO2 emissions in major emerging economies. The findings support the global push for integrated decarbonization strategies and are relevant to international climate policy discussions, especially for countries balancing multiple mitigation options.

👥 読者別の含意

🔬研究者:This paper offers rigorous econometric evidence on the long-term emission reduction effects of afforestation, energy productivity, and low-carbon electricity sources, useful for researchers in energy-environment economics and climate policy.

🏢実務担当者:Corporate sustainability teams can draw insights on the importance of energy productivity improvements and renewable/nuclear sourcing as long-term strategies for emission reduction, and consider afforestation as a nature-based solution.

🏛政策担当者:Policymakers in emerging economies can use these findings to prioritize afforestation, energy productivity, and clean electricity generation in their NDCs and long-term decarbonization plans.

📄 Abstract（原文）

Global warming and climate change have considerably enhanced worldwide environmental concerns since the 1970s. Therefore, researchers have extensively researched the nexus between renewable energy utilization and CO2 emissions in the literature. However, the influence of afforestation and energy productivity along with renewable and nuclear electricity generation on CO2 emissions has not been explored sufficiently in the associated literature regarding the multiple effects of these actors on the decarbonization process. Thus, this article analyzes the short- and long-term effects of afforestation, energy productivity, renewable and nuclear electricity production on CO2 emissions in the BRICS states over the 1993–2021 term via robust bootstrap cointegration and causality tests. The findings confirm a cointegration interplay among CO2 emissions, afforestation, energy productivity, renewable and nuclear electricity generation. Further, the cointegration coefficients demonstrate a negative influence of afforestation, energy productivity, renewable electricity generation on CO2 emissions in most of the BRICS states in the long term, but a negative effect of nuclear electricity production only in China and the Russian Federation. The findings of causality examination also uncover that afforestation, energy productivity, and generation of renewable and nuclear electricity are effective tools in reducing CO2 emissions, but their long-term effects are found to be relatively higher than short-term effects. These findings indicate that promotion of afforestation, along with energy productivity and electricity from renewables and nuclear sources is highly useful for curbing CO2 emissions in the short and long term.
