Environmental regulations have emerged as a critical policy tool for promoting environmental sustainability worldwide. However, there is a dearth of literature that investigates the impact of environmental regulations on load capacity factor in Asia-Pacific Economic Cooperation (APEC) economies. This study aims to address this gap by examining the role of renewable energy consumption, human capital, and environmental regulations in improving load capacity factor. In doing so, the paper covers 14 APEC economies; applies second generations panel data models (i.e., CUP-FM (continuously updated fully modified) as the base model and CUP-BC (continuously-updated and bias-corrected) for the robustness); and runs data between 1992 and 2018. The empirical findings present that: i) renewable energy consumption and human capital contribute to improving load capacity factor; ii) environmental regulations are not at a level to increase load capacity factor; iii) economic growth and trade openness significantly reduce load capacity factor. Considering empirical outcomes, this study suggests that APEC should tighten environmental regulations to achieve sustainable environment. In addition, this study offers important sustainable environmental policies for APEC within the framework of empirical findings.

环境法规已成为促进全球环境可持续性的重要政策工具。然而，缺乏研究环境法规对亚太经济合作组织（APEC）经济体负荷能力系数影响的文献。本研究旨在通过研究可再生能源消耗、人力资本和环境法规在提高负载能力系数方面的作用来解决这一差距。在此过程中，本文涵盖了 14 个 APEC 经济体；应用第二代面板数据模型（即，CUP-FM（持续更新完全修改）作为基础模型，CUP-BC（持续更新和偏差校正）作为稳健性）；并运行 1992 年至 2018 年间的数据。实证结果表明：i）可再生能源消耗和人力资本有助于提高负荷能力系数；ii) 环境法规未达到提高负载能力系数的水平；iii) 经济增长和贸易开放显着降低了载客能力系数。考虑到实证结果，本研究建议APEC应加强环境法规以实现可持续环境。此外，本研究在实证研究框架内为 APEC 提供了重要的可持续环境政策。
