This study by Ecologic Institute examines the current landscape of lighting efforts and initiatives, as well as market growth and development for modern, sustainable off-grid lighting alternatives. The study considers the benefits and costs of upgrades in target regions, particularly Sub-Saharan Africa and South Asia. Policy recommendations are given for action from the Climate and Clean Air Coalition (CCAC) that would enhance existing efforts and achieve more rapid black carbon reductions and climate benefits.
