This report synthesizes the results of studies conducted under an ADB technical assistance on the Regional Economics of Climate Change in South Asia Phase 1 (RECCSA 1) in five countries (Bangladesh, Bhutan, Maldives, Nepal, and Sri Lanka). The studies estimated the likely growth of GHG emissions to 2030 under a scenario of expected energy-use mixes, including penetration of some clean technologies, and the impact of a climate policy in the form of a carbon tax to stabilize GHG production at an acceptable level. Overall, technology access, policy and financing issues will continue to influence the development of clean technologies and move toward low-carbon growth in South Asia. Large-scale development of clean energy resources to significantly reduce carbon intensity and GHG emissions will be crucial. This can be achieved by South Asian countries by prioritizing investments in technologies across sectors with low incremental abatement costs and other co-benefits, such as reducing emissions of other locally-damaging pollutants and providing economic opportunities for communities.
