Replication Data for: "How Peace Treaties Can Influence Countries’ Climate Policies"

Peace agreements increasingly contain environmental provisions, yet we know little about the impact these clauses might have. This study is the first to systematically assess whether and how environmental terms in in peace treaties can influence states’ climate policies. I argue that peace accords help establish the foundations for legalization and the rule of law in post-conflict societies, which facilitates that environmental terms lead to actual legislation. I analyze over 2,000 peace agreements and thousands of climate mitigation policies from 1990 to 2024, using multiple estimation strategies. The findings show that peace agreements’ environmental provisions are associated with the adoption of climate policies in post-conflict periods. This relationship holds even when exploring environmental outcomes, accounting for countries’ self-selection into environmental terms, or considering moderating factors like institutional capacity. The study contributes to the literature on peacebuilding and environmental politics, offering new insights into how peace agreements can shape post-conflict settings.
