While a carbon tax is widely acknowledged as an efficient policy to mitigate climate change, adoption has lagged. Part of the challenge resides in the distributional implications of a carbon tax and a belief that it tends to be regressive. Even when not regressive, poor households could be hurt by a carbon tax, particularly in countries that rely heavily on carbon-intensive energy sources. Using household surveys, the study how a carbon tax may affect households in the Asia Pacific region, the main source of CO2 emissions. It document a wide range of country-specific policies that could be implemented to compensate households, reduce inequality, and build support for adoption.
