National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas
Sustainable Development, EarlyView.ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...
