Mexico is committed to reduce its emissions from its projected Business as Usual (BAU) baseline by the year 2030 (Mexico NDC, 2020). NDC’s implementation timeframe spans from 2020 to 2030. In this scenario, 991 MtCO2e were quantified in 2030. They posited an unconditional contribution to reduce 22% of GHG emissions and a conditional contribution of up to 36% reduction below BAU, 774 MtCO2 and 638 MtCO2, respectively (Climate Action Tracker, 2020).

Mexico plans to cover all sectors. In a cross sectoral approach, the main measures outlined are Emission Trade System; Climate Finance Strategy, Circular Economy, Efficient Use of Energy. In the transport sector, Mexico aims the strengthening of regulations applicable to motor vehicles, the encouragement of alternative transportation systems, the promotion of clean transportation programs, the development and implementation of the National Electric Mobility Strategy and urban planning. In the electricity sector, it aims to increase participation of renewables, storage and smarter grids. Additionally, in the building sector the focus is on projects that optimize energy consumption in buildings and reduce the impacts of new constructions; to promote mechanisms and regulations that encourage the inclusion of best practices in constructions. Energy efficiency and circular economy are the kernel for the industrial sector.

According to Climate Action Tracker (2020), although both conditional and unconditional remained unchanged from Mexico’s 2016 NDC, its emission projections under BAU has been revised upwards. Therefore, the mitigation ambition has decreased.
