2017〜2024年に新たに建設された大規模風力・太陽光発電を全球で特定し、生態学的完全性に基づいて加重した曝露指標を開発。高完全性地域での再生可能エネルギー拡大が特に生態学的負荷が大きいことを定量的に示し、統合的環境管理への応用可能性を提示する。
English
This study develops a globally reproducible framework to assess ecological exposure from utility-scale wind and solar expansion, using satellite data and ecological integrity metrics. It finds that while only about one-quarter to one-third of regional expansion occurs in high-integrity landscapes, these areas account for 88–93% of integrity-weighted exposure, highlighting the need for biodiversity-sensitive siting.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも再生可能エネルギー導入拡大に伴い、自然環境との調和が課題。本フレームワークは、日本の限られた国土での適地選定や環境アセスメントに応用可能であり、SSBJやESG情報開示における「自然関連財務情報開示タスクフォース（TNFD）」の実践にも貢献しうる。
In the global GX context
As global renewable energy capacity surges, the ecological implications of siting decisions become critical. This paper provides a data-driven, reproducible method to evaluate where expansion poses the highest ecological risk, directly supporting frameworks like TNFD and ISSB’s biodiversity-related disclosures, and informing spatial planning for a nature-positive energy transition.
👥 読者別の含意
🔬研究者:Researchers in spatial ecology and energy systems can use the proposed indicators to quantify trade-offs between renewable deployment and ecological integrity.
🏢実務担当者:Corporate sustainability teams and environmental consultants can adopt this framework for cumulative-effects screening and site selection in renewable energy projects.
🏛政策担当者:Regulators and spatial planners can leverage the integrity-conditioned approach to guide permitting and zoning policies that balance clean energy goals with biodiversity conservation.
📄 Abstract（原文）
<title>Abstract</title> <p>The rapid expansion of utility-scale wind and solar energy creates a growing environmental management challenge: how to assess not only deployment magnitude, but also the ecological context of siting. This study develops a globally reproducible, integrity-conditioned indicator framework for assessing ecological exposure from renewable energy expansion using publicly available geospatial data. New renewable build-out first observed between 2017 and 2024 is identified from successive Global Renewables Watch snapshots and linked to administrative boundaries, the Global Human Modification dataset, and the Human Footprint index. Two complementary indicators are proposed: the Renewable Infrastructure Ecological Pressure Index, which weights newly observed renewable area by baseline ecological integrity, and the Renewable Land-use High-Integrity Pressure Index, which measures the share of expansion located in the highest-integrity fraction of landscapes within each jurisdiction. Results show that footprint growth and integrity-conditioned exposure are related but not equivalent. High-scale, high-integrity regional units account for only about one-quarter to one-third of observations but for roughly 88–93% of integrity-weighted exposure. Upper-tail exposure in the most intact landscapes is selective rather than universal. Sensitivity analyses indicate that the main monitoring signal is robust under moderate specification changes. The framework captures exposure-weighted pressure rather than realized biodiversity impact and provides an updateable basis for environmental assessment, cumulative-effects screening, spatial planning, and biodiversity-sensitive renewable deployment.</p>
