Mexico's Yearly Greenhouse Gas Emissions in CO₂ Equivalent

✨ Key Insights

Early Industrialization and Oil Nationalization

Mexico's greenhouse gas emissions have evolved significantly since the mid-19th century. The early 20th century saw a modest increase in emissions, largely due to industrialization and the nationalization of the oil industry in 1938. The creation of PEMEX marked a pivotal moment, as domestic oil production surged, leading to increased CO₂ emissions from fossil fuels. This trend continued with the discovery of the Cantarell oil field in 1974, further boosting Mexico's oil output and associated emissions.

Agricultural Advances and Trade Agreements

The Green Revolution in the 1960s introduced modern agricultural techniques, increasing productivity but also raising N₂O emissions due to synthetic fertilizer use. The implementation of NAFTA in 1994 spurred industrial growth and trade, contributing to higher CO₂ emissions from manufacturing and transportation. Concurrently, the expansion of the livestock industry around 2000 led to a rise in CH₄ emissions, driven by increased cattle production.

Recent Developments and Challenges

In recent years, Mexico's energy reforms have aimed to balance fossil fuel reliance with renewable energy development. However, the 2013 energy reform, while opening the sector to private investment, primarily increased CO₂ emissions from fossil fuel extraction. The COVID-19 pandemic in 2020 temporarily reduced emissions due to decreased industrial activity, but this was a short-lived reprieve as economic activities resumed. The ongoing challenge for Mexico remains in managing emissions while pursuing economic growth and energy security.

Background

Greenhouse gas emissions from human activities are the main drivers of human-induced warming. In the scientific literature, human-induced emissions are often referred to as anthropogenic emissions.

CO₂ Fossil Fuels and Industry (CO₂ FFI)
CO₂ Land-Use, Land-Use Change and Forestry (CO₂ LULUCF)
Methane (CH₄)
Moderate: above 2.5 tonnes
Nitrous oxide (N₂O)
Fluorinated gases (F-gases)

Emissions from all different gases are expressed in CO₂-equivalent units to make it possible to compare the relative emissions from these different gases. CO₂-equivalents are calculated using the global warming potentials of the respective gases, in this case using a 100-year time horizon.

CO₂ From Fossil Fuels and Industry

The sources are mostly fossil-fuel combustion emissions from coal, oil, and gas, as well as emissions from industrial processes such as cement production. Cement also absorbs CO₂ out of the atmosphere through carbonation, which reduces emissions by about 0.8 Gt per year and is included here.

CO₂ From Land-Use, Land-Use Change, and Forestry

The main driver of these emissions is deforestation, which includes logging and forest degradation, as well as other land-use change activities. The emissions also take into account the absorption of CO₂ by processes that remove CO₂ from the atmosphere, such as afforestation and reforestation. It is the net effect that is indicated here.

Methane (CH₄)

Methane emissions are caused by human activities such as rearing livestock, agricultural practices, and fugitive fossil fuel emissions.

Nitrous Oxide (N₂O)

Common sources of these emissions are fossil fuel emissions and the agricultural use of synthetic fertilizer and manure.

Fluorinated Gases (F-gases)

Fluorinated gases are a group of gases defined by UNFCCC: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). Fluorinated gases are also known as halogenated gases.

Units and Measures

CO₂-equivalent emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

About the Data

The last available year in all the emission datasets is 2023. CO₂ emissions data is from the Global Carbon Project. It contains national CO₂ emissions from fossil sources and land-use change. Emissions from CH₄, N₂O and F-gases come from the PRIMAP-Hist dataset. It is a rich dataset that combines several published sources to create a historical emissions time series for various greenhouse gases.

The Key Insights paragraph was generated using a large language model (LLM) using a structured approach to improve the accuracy. This included separating the context generation from the interpretation and narrative.
