Mexico’s GHG Inventory Reports Are Good But Dated

Rating: C 

This Post 68 reports on the status of Mexico’s greenhouse gas emissions inventory and describes the organizations responsible for organizing its data. Mexico releases a national inventory of greenhouse gas emissions every four years. The last Mexico Greenhouse Gas (GHG) Inventory Report was released in 2018. The inventory is a public document and can be downloaded from the website of the Instituto Nacional de Ecología y Cambio Climático (INECC), the Mexican government agency responsible for compiling and releasing the inventory, and the government agency responsible for climate change and environmental matters.

With this GHG inventory, Mexico compiles its inventory based on data collected from various national sources such as government agencies, research institutions, and other relevant stakeholders. Mexico also uses data from external sources, such as the International Energy Agency (IEA) and the United Nations Emissions Database for Latin America and the Caribbean (UNEP-RLA). The inventory is prepared following international guidelines and standards, such as those provided by the Intergovernmental Panel on Climate Change (IPCC).

The primary organization responsible for compiling and releasing Mexico’s greenhouse gas inventory reports is the Mexican Ministry of Environment and Natural Resources (SEMARNAT, for its letters in Spanish) and its INECC. The information is collected through a collaborative effort involving various government departments, agencies, research institutions, and data providers. The INECC has developed a set of guidelines for data submission, which can be found on its website.

The key personnel responsible for managing the INECC’s GHG Inventory Report is Dr. Agustín Ávila Romero, Head in charge of the Office of the General Directorate of INECC; Other critical contact information is available on the INECC’s website.

Mexico’s GHG Inventory Report released in 2018 covered emissions from 1990 to 2016. The following inventory is scheduled to be released in 2022 and will cover emissions from 1990 to 2020.

Mexico’s GHG Inventory Report provides information on the total amount of greenhouse gases released during the reporting period, different types of emissions (e.g., CO2, methane, nitrous oxide), and the leading sources of emissions (e.g., energy, transportation, agriculture). The highlights of Mexico’s latest GHG inventory report are:

  • Total GHG emissions were 784 million metric tons of CO2 equivalent (MtCO2e), an increase of 44% from 1990.
  • The energy sector appeared as the largest source of GHG emissions, accounting for 72% of total emissions.
  • Other significant sources of GHG emissions include agriculture (16%), industry (7%), and waste (5%).

Mexico’s GHG Inventory Report provides insights into trends and issues in emissions that include changes in emissions from specific sectors, progress toward emissions reduction targets, and the effectiveness of mitigation measures. Mexico’s GHG Inventory Report shows that GHG emissions have increased steadily in recent years. This is due to several factors, including economic growth, population growth, and increased energy consumption.

Mexico’s GHG Inventory Report also highlights several key trends in emissions that need to be addressed by policymakers. These include:

  • The use of natural gas as well as coal drives the growing share of emissions from the power sector.
  • The rising share of emissions from agriculture is driven by the expansion of livestock production and the use of fertilizers and pesticides.
  • The increasing share of emissions from industry is driven by the growth of manufacturing and the use of heavy machinery.

Using the Climate Scorecard rating system, Mexico’s ability to produce timely, reliable, informative greenhouse gas emission reports is C.
