このレビューは、気候緩和・適応ポートフォリオの初期設計段階で活用できる「気候環境品質（CEQ）」スクリーニング枠組みを提案する。炭素指標だけでなく、大気・水・土壌・生態系・公衆衛生への影響を考慮し、介入策を「後悔しない」「条件付き」「日和見」「回避/優先度低」に分類する。高信頼の選択肢としてクリーン電力、エネルギー効率、メタン削減などを挙げる一方、BECCSや土壌炭素クレジット、CCS/CCUSなどは文脈依存と位置づける。意思決定者が低炭素だけでなく環境品質と社会的耐久性を備えたポートフォリオを構築するための透明なスクリーニングツールとして機能する。
English
This Review proposes a Climate-Environmental Quality (CEQ) screening framework for early-stage design of climate mitigation and adaptation portfolios. It goes beyond carbon metrics to consider impacts on air, water, soil, ecosystems, public health, and communities, classifying interventions as no-regrets, conditional, opportunistic, or avoid/deprioritize based on confidence, co-benefits, trade-offs, equity, and safeguards. High-confidence options include clean power, energy efficiency, and methane abatement, while BECCS, soil carbon crediting, and CCS/CCUS are context-dependent. CEQ serves as a transparent screening tool for decision-makers to design portfolios that are low-carbon, environmentally protective, and socially durable.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は、日本企業がGXポートフォリオを策定する際に、炭素削減だけでなく環境品質（大気・水・生態系）への影響を評価する枠組みを提供する。SSBJや有報における気候関連開示では、気候リスクと機会の評価が求められており、CEQフレームワークは多面的な影響評価の考え方として参考になる。特に、日本での自然解ベースの解決策（例：森林管理、湿地再生）やCCSの導入判断に際し、条件付きリスクを明確化する手法として有用。
In the global GX context
This paper offers a decision-support framework that complements TCFD/ISSB-aligned climate disclosures by moving beyond carbon-only metrics to include environmental quality co-benefits and trade-offs. It is particularly relevant for transition finance and climate portfolio design, helping investors and corporates assess not only decarbonization potential but also broader sustainability impacts. The CEQ framework's classification of interventions (no-regrets vs. context-dependent) can inform ISSB's guidance on scenario analysis and resilience assessment.
👥 読者別の含意
🔬研究者:Provides a structured heuristic for integrating environmental quality into climate portfolio evaluation, useful for researchers developing multi-criteria decision-support tools.
🏢実務担当者:Corporate sustainability teams can use the CEQ framework to screen and prioritize climate interventions beyond carbon metrics, informing ESG reporting and transition planning.
🏛政策担当者:Policymakers can adopt the CEQ approach to evaluate climate portfolios for environmental and social co-benefits, aligning with sustainable finance taxonomies.
📄 Abstract（原文）
Climate mitigation and adaptation are often evaluated through carbon metrics, but climate actions also redistribute effects across air, water, soils, ecosystems, public health, and communities. This Review narrows its contribution to a Climate-Environmental Quality (CEQ) screening framework for early-stage climate portfolio design. CEQ is presented as a heuristic decision-support protocol, not as a substitute for life-cycle assessment, environmental impact assessment, integrated assessment modeling, legal consultation, or a validated quantitative index. We synthesize recent evidence on technological decarbonization, nature-based and land-management solutions, governance and finance, and community implementation, while distinguishing high-confidence consensus claims from context-dependent evidence and illustrative examples. The framework classifies interventions as no-regrets, conditional, opportunistic, or avoid/deprioritize by combining climate-benefit confidence, environmental-quality co-benefits or trade-off risk, equity and acceptance sensitivity, and safeguards/MRV readiness. We add explicit calibration guidance, uncertainty rules, and a worked farm-watershed example to show how CEQ can convert broad climate claims into transparent screening judgments. The synthesis supports high confidence for options such as clean power, energy efficiency, and methane abatement when safeguards are credible, while treating BECCS, soil carbon crediting, nitrification inhibitors, wetland restoration, CCS/CCUS, and carbon markets as context-dependent options requiring conservative accounting and local calibration. CEQ is therefore best used as a transparent screening and learning tool that helps decision makers ask whether climate portfolios are not only low-carbon, but also protective of environmental quality and socially durable.
