Scale, Depth and Duration: Examples of Transformational Change in the Energy and Public Health Sectors

The study analyses robust, causal evidence of transformational change. We approach this topic by systematically reviewing literature that has the potential to document causal evidence for transformational change across a broad set of interventions and outcomes. Our focus is on evidence found in developing countries to inform climate interventions. We approach this learning exercise directly by looking at the energy sector and indirectly by reviewing the evidence on behavioural change in the public health sector. Both sectors show examples of transformational change with scale, depth and duration. We identify lessons on transformational change from these two sectors relevant to policymakers.
