As nations fail to meet their climate emission mitigation goals, the ambition gap is widening between international climate policy (enacted by the United Nations) and domestic climate policy (what nations propose and enact). A widely held but little verified conventional wisdom exists that nations over-promise internationally and under-deliver domestically. While little data exist to directly test this hypothesis, we documented this gap by constructing heuristic indexes of domestic and international climate policy performance, showing that nations tend to &ldquo:lead with the international&rdquo:. We found that nations&rsquo: domestic policies are not significant in explaining emissions, although their international policies are significant. We concluded that beyond identifying this gap, analysts must devise metrics to assess domestic climate policy across a range of issue areas, as domestic policies are the foundation of any global effort to manage climate change.
