日本語
本書章は、エネルギー部門を中心に排出削減機会・緩和コスト・主要な緩和政策を整理する。炭素税と排出量取引制度（ETS）の根拠、サプライチェーン上の適用点やコスト不確実性の含意、価格設定・歳入活用・価格安定化・無償割当などの設計論を論じる。さらにフェーベートや取引可能な性能基準といった部門別補完手段、低炭素技術への補助金・義務化の限界と設計上の改善点を解説する。
English
This chapter reviews mitigation opportunities, costs, and policies, mainly in the energy sector. It examines the rationale and design of carbon pricing (carbon taxes and ETSs), including supply-chain application points, cost uncertainty, revenue use, price stability, and allowance allocation. It also assesses sectoral instruments like feebates and tradable performance standards, plus the limits and design fixes for subsidies and mandates.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではGXリーグ・GX-ETSや炭素賦課金（2028年度）導入を控え、価格帯設計・部門別措置・歳入使途の論点はSSBJ開示と投資家対応に直結する。政策当局・企業の制度設計担当者にとって実務的参照価値が高い。
In the global GX context
As ISSB/CSRD disclosure expands and jurisdictions debate carbon border adjustments and ETS linkage, this chapter offers a structured framework for instrument choice and design—useful for comparing tax-based versus trading-based approaches and for evaluating supplementary sectoral policies.
👥 読者別の含意
🔬研究者:炭素価格と部門別政策の設計比較に関する整理された枠組みを提供する。
🏢実務担当者:自社の炭素コスト・Scope排出への価格制度影響と、補助金・義務化の活用可能性を検討する際の基礎となる。
🏛政策担当者:炭素税・ETS・フェーベート・性能基準の設計選択と、歳入・価格安定化・割当の実務論点を整理する。
📄 Abstract（原文）
This chapter begins with some basics on emissions reduction opportunities, mitigation costs and their minimization, and commonly used mitigation policies, mostly focusing on the energy sector. It then discusses the rationale for carbon pricing schemes, including carbon taxes and emissions trading system (ETSs), and the implications of applying them at different points in supply chains and of mitigation cost uncertainty. Design issues are also discussed, including administration, setting prices, and (for taxes) use of revenues or (for ETSs) price stability mechanisms and allowance allocation. This chapter then discusses the rationale for supplementary, sectoral level mitigation instruments. Feebates and tradable performance standards are the most promising instruments and their attributes, along with implementation issues for different energy sectors, are explained. Low-carbon technology subsidies and mandates are then discussed, emphasizing limits on their effectiveness as well as (in the former case) fiscal costs and (in the latter case) lack of cost-effectiveness, but also noting design features to improve their effectiveness, cost-effectiveness, and limit fiscal burdens.
