本稿は、在来型ガスを一律の「橋渡し燃料」とも「本質的に非整合な化石燃料」とも見なさず、その移行期の役割は条件付き・システム固有・地域差・時間限定的だと論じる。資源の成熟度、インフラ接続、市場接続性、商業条件によって移行価値が異なるとし、石炭からガスへの転換には実際の石炭代替、ライフサイクル排出削減、検証されたメタン管理、長期的なインフラ固定化の回避が必要と指摘する。既存インフラを活用し明確なシステム需要に応える場合に最も正当化されると結論づける。
English
This chapter argues conventional gas is neither a universal bridge fuel nor inherently incompatible with decarbonization; its transitional role is conditional, system-specific, regionally differentiated, and time-bound. Transitional value varies with resource maturity, infrastructure access, market connectivity, and commercial conditions. Coal-to-gas substitution requires actual coal displacement, lower life-cycle emissions, verified methane control, and limited long-term lock-in. Gas is most defensible where it meets defined system needs using existing infrastructure without reinforcing long-term fossil dependence.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はLNG依存度が高く、GX推進法・第7次エネルギー基本計画でガスの移行期活用と脱炭素化の両立が焦点。本稿の「条件付き橋渡し」論は、電力・産業の脱炭素ロードマップやLNG調達戦略、メタン管理規制の議論に直接示唆を与える。
In the global GX context
As global disclosure frameworks (ISSB, CSRD) push Scope 1/2/3 and methane reporting, this chapter reframes gas transition claims as conditional and verifiable. It informs transition-finance taxonomies and gas-investment eligibility debates, emphasizing methane control and lock-in avoidance as disclosure-relevant criteria.

📄 Abstract（原文）
The global energy system is undergoing a transition to reduce greenhouse gas emissions while maintaining a secure, affordable, and reliable energy supply. Conventional gas remains in use for power generation, industry, buildings, and chemical production, and it continues to shape regional and international gas trade. However, its role in the energy transition is not fixed. As a heterogeneous resource category, its transitional value varies with recoverability, production maturity, infrastructure access, market connectivity, and commercial conditions. The analysis shows that mature resources connected to existing infrastructure have different transition implications compared to frontier projects that require new infrastructure. This chapter examines how uneven resource distribution, production maturity, infrastructure legacy, and domestic or export-oriented development pathways shape the market accessibility, lock-in exposure, and demand uncertainty of conventional gas. It also evaluates the functions that gas may perform in power systems, industry, energy security, and fuel substitution. In particular, coal-to-gas substitution requires actual coal displacement, lower life-cycle emissions, verified methane-emissions control, and limited long-term infrastructure lock-in. The chapter concludes that conventional gas should not be treated as either a universal bridge fuel or an inherently incompatible fossil fuel. Instead, its transitional role is conditional, system-specific, regionally differentiated, and time-bound. Conventional gas is most defensible where it addresses clearly defined system needs, uses existing infrastructure where possible, and does not reinforce long-term dependence on unabated fossil fuels.
