Abstract:-
Climate change mitigation is often assumed to be cheaper in developing countries than in developed countries. Yet, existing analyses frequently ignore the cost-effectiveness of price-based climate policies in the presence of other externalities such as indoor air pollution. Using detailed household data for six representatively selected countries, we examine the demand responses of biomass consumption to higher prices of electricity, liquefied petroleum gas (LPG) and kerosene. We show that for these fuels, carbon pricing can generate substantial domestic health costs resulting from increasing indoor air pollution that exceed the global benefits of climate mitigation in four out of six countries. Our results challenge the notion that climate change mitigation is cheaper in low-income countries relative to high-income countries. The design of climate policies needs to take contextual factors into account, in particular with respect to the fuels used by the poorest.
