パリ協定の排出削減公約は国内選好の表現とされるが、政府は他国の行動を左右する戦略的意図を持つ。40人の政策担当者へのインタビューから、気候資金の誘致、基準設定、地位向上、信頼性維持、国内行動促進、将来政府への事前コミットの6つの戦略的目的を特定。国際的アクターが主な標的であり、信頼性への懸念が野心を制約する場合もある。高排出国や民主化度の低い国は長期的信頼性を重視し、気候資金適格国は所得に関わらず資金誘致を目指す。

English

This study empirically examines strategic motives behind national climate pledges under the Paris Agreement. Based on interviews with 40 policymakers, it identifies six strategic objectives, including attracting climate finance, setting standards, and preserving credibility. International actors are the primary audience. Higher emitters and less democratic states emphasize long-term credibility, while climate-finance-eligible countries seek funding regardless of income. Findings have implications for ratcheting up global climate commitments.

📄 Abstract(原文)

Abstract Emissions-reduction pledges under the Paris Agreement are commonly understood as expressions of domestic preferences. Recent scholarship, however, suggests that governments may also use climate pledges strategically to shape the behavior of other political actors. Here, we provide an empirical account of these strategic objectives based on in-depth interviews with 40 policymakers and experts. We identify six key strategic objectives: attracting international climate finance, setting standards for others, enhancing status, preserving credibility, facilitating domestic action, and pre-committing future governments. International actors emerge as the primary target audience. These objectives have distinct implications for ambition. While most encourage stronger pledges, concerns about credibility can constrain ambition. In an exploratory analysis, we also examine how strategic objectives vary across countries. The findings suggest that higher emitters and states with lower levels of democratic institutionalization place greater emphasis on long-term credibility, while countries eligible for climate finance seek to attract it regardless of income or vulnerability. Our findings have implications for ratcheting up international climate commitments.
