CMIP6モデルデータを用い、SSP1-1.9（炭素中立経路）と高排出シナリオ下での世界の風力エネルギー変化を比較した。SSP1-1.9は北半球の風力減少を緩和し南半球の増加を抑制することで、風力資源の安定性維持に有利であることが示された。累積CO2排出量の差が拡大するほど、この効果は顕著になる。炭素中立政策の便益評価と将来の風力発電計画に科学的根拠を提供する。
English
Using CMIP6 model data, this study compares global wind energy changes under the carbon-neutral SSP1-1.9 pathway versus higher-emission scenarios. SSP1-1.9 better preserves wind energy stability by reducing Northern Hemisphere declines and constraining Southern Hemisphere increases, with benefits growing as cumulative CO2 emissions diverge. It provides scientific evidence for evaluating carbon neutrality policy benefits and planning future wind power.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策（第7次エネルギー基本計画、再エネ主力電源化）において、長期的な風力資源の安定性評価は洋上風力導入計画や電源構成の不確実性評価に直結する。炭素中立経路が再エネ資源そのものを安定化させるという知見は、政策立案・事業計画の根拠として有用。
In the global GX context
This study adds to global transition finance and energy planning literature by quantifying how decarbonization pathways themselves stabilize renewable resources, informing ISSB/TCFD-aligned physical risk assessments and long-term renewable investment strategies under net-zero scenarios.

📄 Abstract（原文）
Projection and evaluation of wind energy changes toward carbon neutrality are important for energy planning. However, the benefits of wind energy changes along carbon neutrality or low-carbon development pathways remain understood insufficiently. Based on models’ datasets from the Coupled Model Intercomparison Project Phase 6 (CMIP6), this study explores wind energy changes during the pre-net-zero (2025–2035), net-zero (2050–2060) and net-negative (2090–2100) CO2 emission periods relative to a baseline period (1995–2014) over the global land under SSP1-1.9, which can be regarded as a reference for the carbon neutrality pathway. SSP2-4.5 and SSP5-8.5 are also selected for comparison. The results demonstrate that SSP1-1.9 is more favorable for maintaining the stability of wind energy resources, which will reduce the decline in wind energy over the Northern Hemisphere and constrain the increase over the Southern Hemisphere compared with higher-emission scenarios of SSP2-4.5 and SSP5-8.5. These characteristics become increasingly pronounced as the divergence in cumulative CO2 emissions widens. The reduction in wind energy over the Northern Hemisphere is primarily governed by changes in the frequency of wind speeds below 3 m/s and between 3 and 11 m/s, while the increase in the Southern Hemisphere is dominated by the increased frequency of 3–11 m/s. The divergent changes in wind speed frequency between the two hemispheres are closely associated with their distinct temperature gradient responses to different scenarios. This study highlights the benefit of carbon mitigation measures in maintaining wind energy stability compared with higher-emission pathways. As cumulative CO2 emissions continue to decrease, this benefit becomes increasingly pronounced. The research provides scientific evidence for evaluating the benefits of carbon neutrality policies and planning future wind power resources.
