The Mexican Ministry of Environment and Natural Resources is the government’s central authority for the entire environmental regulatory system in Mexico.
For any international corporation planning to establish a manufacturing or industrial presence in Mexico, navigating the nation’s regulatory landscape extends far beyond tax and labor law. A third, equally critical pillar of compliance is environmental regulation, an area overseen by the powerful federal ministry, the Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT), or the Ministry of Environment and Natural Resources.
SEMARNAT is the cabinet-level entity responsible for the protection, restoration, and conservation of Mexico’s ecosystems, natural resources, and environmental assets. Its mandate is vast. It covers everything from air and water quality to hazardous waste management and the sustainable use of natural resources. Consequently, for any industrial project—from building a new factory to operating an existing one—securing the proper permits and maintaining strict compliance with SEMARNAT’s regulations is a fundamental legal requirement. Failure to do so can result in significant project delays, substantial fines, and even the shutdown of operations.
This guide provides a comprehensive overview of SEMARNAT, designed specifically for business owners, general managers, and operations directors. We will explore the Ministry’s core functions and provide a detailed breakdown of its most important sub-agencies like PROFEPA and CONAGUA. Also, we will explain the critical permitting processes that impact industrial activities. Ultimately, this document will provide the clarity you need to navigate Mexico’s environmental regulatory framework. This ensures your operation is not only productive but also sustainable and fully compliant.
The Ministry of Environment and Natural Resources is Mexico’s environment ministry. Its head, the Secretary of the Environment and Natural Resources, is a member of the federal executive cabinet and is appointed by the President of Mexico.

The primary mission of SEMARNAT is to create and enforce a national policy of environmental protection that allows for the sustainable development of the country. It seeks to balance the needs of economic growth with the legal imperative to protect the environment and preserve the nation’s rich biodiversity.
Article 4 of the Mexican Constituton, establishes the right of every person to a healthy environment for their development and well-being. The foundational law that gives Mexico’s Ministry of Environment its specific authority is the Ley General del Equilibrio Ecológico y la Protección al Ambiente (LGEEPA), or the General Law of Ecological Equilibrium and Environmental Protection. This comprehensive federal law serves as the primary legal framework for all environmental matters in the country.
To fulfill its mission, SEMARNAT carries out several key functions:
First and foremost, the SE is Mexico’s lead negotiator and administrator for all international trade matters. It is the ministry responsible for pursuing, negotiating, and implementing the country’s vast network of free trade agreements (FTAs).
Mexico’s Ministry of Economy actively works to attract and retain foreign investment. It promotes Mexico’s advantages on the world stage and works to create a secure and predictable environment for international corporations.
This is one of its most critical functions for manufacturers. The SE manages key federal programs, such as IMMEX and PROSEC. These provide significant tax and tariff benefits to companies that manufacture for export.
Through its sub-agencies, the SE is responsible for the national system of patents, trademarks, and industrial designs, which is a critical function for any innovative compan
The Mexican Ministry of Economy also works to improve the competitiveness of domestic companies and foster the development of local supply chains that can integrate with large multinational corporations.
In short, SEMARNAT is the central authority for the entire environmental regulatory system in Mexico. This makes it a key stakeholder for any industrial operation.
Mexico’s Ministry of Environent’s broad mandate is executed through several powerful and specialized sub-agencies. For a business, understanding the specific jurisdiction of each of these bodies is crucial, as you will likely interact with more than one during the permitting and operational phases.
The Procuraduría Federal de Protección al Ambiente (PROFEPA), or the Federal Attorney for Environmental Protection, is the primary enforcement arm of SEMARNAT. Think of PROFEPA as the “environmental police.”
PROFEPA’s main mission is to monitor, inspect, and enforce Mexico’s environmental laws. Its agents have the authority to conduct inspection visits to any industrial facility to verify compliance with the terms of their environmental permits and with all applicable regulations.
If PROFEPA inspectors find violations, they have a wide range of powers. They can issue official warnings and recommendations. Furthermore, they can levy significant fines. In cases of serious or repeated non-compliance, they have the authority to order the temporary or even permanent shutdown of a facility. PROFEPA also prosecutes environmental crimes.
Your company’s primary interaction with PROFEPA will likely be during a facility inspection. Maintaining a state of “inspection readiness” with all environmental permits, waste manifests, and compliance records in order is a critical operational discipline.
The Comisión Nacional del Agua (CONAGUA), or the National Water Commission, is the sole federal authority responsible for the management and administration of all national water resources in Mexico.
Core Function: CONAGUA manages water basins, oversees water infrastructure, and, most importantly for industry, grants the rights for water usage.
Key Permits for Business: Any company that needs to draw water from a federal source (like a river or an underground aquifer) must obtain a water use concession title (Título de Concesión) from CONAGUA. Additionally, any facility that will be discharging wastewater into a national body of water must obtain a wastewater discharge permit (Permiso de Descarga de Aguas Residuales). This permit establishes strict limits on the pollutants the discharged water is allowed to contain. Regular testing and reporting are required to maintain this permit. For many large-scale manufacturing operations, securing these CONAGUA permits is an essential part of the initial setup process.
The Agencia de Seguridad, Energía y Ambiente (ASEA), or the Agency for Safety, Energy, and Environment, is a specialized agency created as part of Mexico’s energy reforms. It is responsible for regulating all environmental and industrial safety aspects of the hydrocarbons sector. Any company operating in the oil and gas value chain—from exploration and production to refining and distribution—falls under the exclusive jurisdiction of ASEA, not the broader SEMARNAT.
For any new industrial project in Mexico, the environmental permitting process managed by Mexico’s Ministry of Environment is one of the most critical and time-consuming steps in the startup phase. The specific permits required will depend on the nature and scale of the operation, but nearly all significant industrial facilities will need to obtain one or both of the following.
The MIA is the foundational environmental permit for any new project that could potentially cause an ecological imbalance or violate environmental laws. This includes the construction of new factories, industrial parks, major infrastructure, and projects in sensitive ecosystems.
The goal of the MIA is to identify, predict, and evaluate the potential environmental impacts of a proposed project before it is built. It is a comprehensive scientific and technical study that forces a company to plan for environmental mitigation from the earliest stages of project design.
The company must hire an authorized environmental consultant to prepare the detailed MIA study. The study must include a description of the project, a baseline analysis of the existing environmental conditions at the proposed site, a detailed identification of all potential impacts (on air, water, soil, flora, and fauna), and a comprehensive plan of preventative and mitigation measures.
The completed MIA is submitted to Mexico’s Ministry of Environment for review. The Ministry’s technical experts will analyze the study and can either:
Authorize the project, often with specific conditions and mitigation measures that the company must legally adhere to.
Deny the project if it is deemed to have unacceptable environmental impacts.
Request additional information if the initial study is incomplete.
The MIA process is complex and can take a significant amount of time, often ranging from 6 to 12 months or more from the start of the study to receiving a final resolution from SEMARNAT. It is a critical path item for any new construction project.
Once a facility is constructed, it often needs a comprehensive license to operate. For many industries that are under federal jurisdiction due to their potential for air emissions, this is the Licencia Ambiental Única (LAU).
The LAU is an integrated operating permit that consolidates several different environmental obligations into a single instrument. It primarily serves as the federal license for air emissions, but it also integrates reporting requirements for water usage, wastewater discharge, and hazardous waste generation.
The LAU is mandatory for specific industries listed in the LGEEPA, including the chemical, automotive, petroleum, paint, and metallurgical industries, among others.
A company must submit a detailed application to SEMARNAT that describes all of its production processes, identifies all points of air emission, and details the equipment and control measures that will be used to comply with legal emissions limits.
Once the LAU is granted, the company must operate in strict accordance with its terms. This includes regularly monitoring and reporting its air emissions through an Annual Emissions and Pollutant Transfer Report (Cédula de Operación Anual – COA).
Beyond the major MIA and LAU permits, businesses must also comply with a range of other specific environmental regulations.
Hazardous Waste Management: Any company that generates hazardous waste (residuos peligrosos) must register with SEMARNAT as a generator. They are legally required to handle, store, transport, and dispose of this waste according to the strict guidelines established in the relevant NOMs. This includes using only authorized transportation and disposal companies and maintaining a detailed manifest (logbook) tracking all hazardous waste from cradle to grave.
Water Usage and Discharge: As mentioned, companies must have the proper concessions and permits from CONAGUA for their water usage and discharge, and must comply with the quality limits established in their permits.
Risk Studies (Estudio de Riesgo): Facilities that handle highly hazardous substances may also be required to prepare a detailed Risk Study, analyzing the potential for accidents and outlining their emergency response plans.
The Secretaría de Medio Ambiente y Recursos Naturales and its powerful sub-agencies are fundamental institutions in the Mexican regulatory landscape. For any industrial company, environmental compliance is not a secondary concern. It is a core operational requirement that directly impacts project timelines, capital costs, and the legal right to operate.
Successfully navigating the complex environmental permitting process—from the initial Environmental Impact Assessment for a new facility to securing the necessary operating licenses and water permits—requires deep technical expertise and a proactive approach. The process is rigorous, the documentation requirements are extensive, and the consequences of non-compliance can be severe.
