This paper discusses a comprehensive strategy for implementing Mexico’s climate mitigation commitments. Progressively increasing carbon prices from current levels of US$3 per ton to US$75 per ton by 2030 would achieve Mexico’s mitigation pledges, while raising annual revenues of 1.8 percent of GDP and cumulatively averting 11,600 deaths from local air pollution. The carbon price would raise fossil fuel and electricity prices, imposing burdens of 2.7 percent of consumption on the average Mexican household. However, recycling carbon pricing revenues would offset most of this burden, and targeted transfers could make the reform pro-poor and pro-equity. Additionally, the economic efficiency costs of carbon pricing (0.3 percent of GDP in 2030) are more than offset by local air pollution and other domestic environmental benefits (before even counting climate benefits). Mexico would need a more ambitious 2030 target if it were to follow many other countries in adopting a midcentury ‘net-zero’ emissions target. To enhance the effectiveness of the mitigation strategy, carbon pricing can be reinforced with sectoral instruments, such as feebates in the transport, power, industry, building, forestry, extractive, and agricultural sectors. Complementary policies are also needed to support public investment in the clean energy transition.
