The industrial sector is one of the main emitters of greenhouse gasses (GHGs) in Mexico, accounting for around 8% of the country’s total emissions. The industries that emit the most GHGs in Mexico are:

• Oil and gas: This industry is responsible for the majority of industrial emissions in Mexico, accounting for around 50% of the total. Emissions from this sector mainly occur in the extraction, processing, and transportation of oil and gas.
• Cement: The cement industry is responsible for around 15% of industrial emissions in Mexico. Emissions from this sector mainly occur in cement production, which requires large amounts of energy.
• Steel: The steel industry is responsible for around 10% of industrial emissions in Mexico. Emissions from this sector mainly occur in steel production, which requires large amounts of energy and raw materials.
• Chemicals: The chemical industry is responsible for around 5% of industrial emissions in Mexico. Emissions from this sector mainly occur in the production of chemicals, which require large amounts of energy and raw materials.

The GHG emissions from Mexican industries contribute to climate change, which is one of the main environmental threats facing the planet. To reduce GHG emissions, it is necessary to implement mitigation measures such as energy efficiency, the use of renewable energies, and carbon capture and storage.

Some actions that can be taken to reduce GHG emissions from Mexican industries include:

• Incorporating energy efficiency technologies into industrial processes. This can help reduce energy consumption and, therefore, GHG emissions.
  
• Using renewable energies, such as solar and wind power, to generate electricity. This can help reduce dependence on fossil fuels, which are a significant source of GHG emissions.
  
• Purchasing carbon credits. This system allows companies to offset their emissions by purchasing carbon credits, which are used for conservation in forests, jungles, and mangroves.

Industries play a fundamental role in the Mexican economy. However, they are also significant emitters of greenhouse gasses. 

To reduce the environmental impact of industries, measures such as energy efficiency, reduced use of fossil fuels, and carbon capture and storage must be implemented.
