ジガワ州が2026年1月に公表した初の気候変動政策（JSCCP）が、ナイジェリア国家気候変動政策およびNDC 3.0と整合するかを文書比較で検証。制度設計は完全整合だが、適応・農業は部分整合、再生可能エネルギー目標は2021年版NDCの数値を流用し不整合。カツィナ州との比較から、サブナショナルGHGインベントリとMRV基盤の欠如という共通課題を指摘する。
English
This study assesses whether Jigawa State's 2026 Climate Change Policy aligns with Nigeria's National Climate Change Policy and NDC 3.0 via criterion-based document analysis. Institutional architecture is fully aligned, adaptation and agriculture partially aligned, but renewable energy targets are misaligned, reproducing 2021 NDC figures. Comparison with Katsina reveals shared gaps: absent subnational GHG inventories and public MRV platforms.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ基準や自治体の気候計画と国NDCの整合が議論されており、サブナショナル政策の整合性評価枠組みは自治体GX計画の検証手法として参考になる。MRV基盤の欠如という指摘は、日本の地方自治体における排出量算定・開示体制の整備課題とも通底する。
In the global GX context
As ISSB/SSBJ adoption pushes disclosure down to subnational and corporate levels, this paper offers a replicable alignment framework for testing whether local climate plans genuinely track national NDCs. Its finding that financing ambitions outrun subnational MRV capacity echoes global concerns about the credibility of transition plans beyond national borders.

📄 Abstract（原文）
Jigawa State published its first dedicated Climate Change Policy (JSCCP) in January 2026, presenting it as aligned with Nigeria’s National Climate Change Policy (NCCP, 2021–2030) and Third Nationally Determined Contribution (NDC 3.0), transmitted to the UNFCCC in September 2025. This study evaluates that claim through a criterion-based comparative document analysis. The vertical comparison assesses JSCCP against the NCCP and NDC 3.0, while the horizontal comparison examines the Katsina State Green Growth Agenda (KAGGA), drawing on contemporaneous secondary evidence because its primary text was not publicly accessible. Using a three-category alignment framework full, partial, and misalignment—the analysis finds that JSCCP’s institutional architecture is fully aligned with the national model established under the Climate Change Act, 2021. Its adaptation and agriculture provisions are partially aligned, while its most quantifiable mitigation commitment renewable energy is misaligned, as it reproduces targets from Nigeria’s 2021 Updated NDC rather than the updated figures in NDC 3.0. The Katsina comparison suggests that its governance model, earmarked financing mechanism, and externally validated ranking provide more visible accountability mechanisms than JSCCP currently offers, although causal links between the ranking and reported funding increases cannot be established. Both policies share a structural challenge identified in NDC 3.0: financing ambitions exceed documented subnational institutional capacity, alongside the absence of operational subnational greenhouse gas inventories and public MRV platforms. The study recommends reconciling JSCCP targets with NDC 3.0, strengthening subnational MRV capacity, and institutionalising independent climate-governance assessment.
