Mexico | Greenhouse Gas Emissions and mitigation and adaptation actions

We are just days away from COP26. According to its Nationally Determined Contribution (NDC), it is estimated that Mexico emitted 804 million metric tons of CO2e in 2020. As a signatory to the Paris Agreement, Mexico commits to reduce its Greenhouse Gases by 22% by 2030, in the unconditional case.

Key points

  • Key points:
  • Mexico has a General Law on Climate Change, created in 2012 and amended in 2018 to establish the figure of the "Nationally Determined Contributions (NDC)" and its commitment to the set of objectives and goals, assumed by Mexico, in the framework of the Paris Agreement, in terms of mitigation and adaptation to climate change.
  • In the NDC update, it was estimated that Mexico emitted 804 million metric tons of carbon dioxide equivalent (MtCO2e) from Greenhouse Gases in 2020, which represented about 1.3% of global emissions. We would have to wait for the final estimate that fully considers the effects of the COVID-19 pandemic.
  • Mexico established two goals in the mitigation component in its NDC updated to 2020: 1) reduce national emissions of Greenhouse Gases by 22% by 2030 in the “unconditional” case and by 36% in the “conditioned” case, and 2) reduce black carbon emissions by 52% by 2030 in the “unconditional” case and by 70% in the “conditioned” case.
  • In 2020, and for the next 10 years, transportation activity is, and will continue to be, the sector that produces the most Greenhouse Gases in Mexico, with around a quarter of the total.
  • Currently, a constitutional reform proposal is being discussed in Congress that could lead to privileging more polluting means of electricity production, such as thermoelectric plants, and that would affect cleaner and more sustainable sources such as solar and wind, which makes it even less likely the achievement of the NDC of Mexico.
