Mexico - Home

The Mexican government has announced a sweeping ban on the production, import, distribution, and use of more than 30 highly hazardous pesticides across the country. Many of these substances are classified as highly toxic, carcinogenic, or persistent organic pollutants (POPs) under international conventions.

The measure represents one of Mexico's most ambitious regulatory steps  in recent years to combat environmental contamination and reduce chemical exposure in agriculture. 

Scientific Backing and International Compliance

The decree cites mounting international and domestic scientific research documenting the adverse effects of chronic pesticide exposure on human health and the environment. According to Mexican health authorities, long-term exposure is associated with:

• Increased risks of cancer, including leukemia, lymphoma, and various organ-specific cancers

• Neurological disorders such as Parkinson’s disease

• Endocrine disruption and reproductive health issues

• Soil and water contamination, affecting biodiversity and food safety

The government also noted the alignment of this decree with international obligations under:

• The Rotterdam Convention (prior informed consent on hazardous chemical trade)

• The Stockholm Convention (elimination of persistent organic pollutants)

• The Montreal Protocol (where applicable to ozone-depleting substances)

Transition Period and Enforcement Measures

While the decree takes effect immediately, authorities have introduced a six-month transition period to allow for safe disposal of existing stocks of the banned substances.

Key provisions include:

• Immediate cessation of all new authorisations, registrations, and permits for the banned substances.

• Revocation or cancellation of existing licenses and registrations by relevant federal agencies.

• Mandatory final disposal of stored pesticides in accordance with hazardous waste regulations.

• Strict exceptions only for scientific research or analytical purposes, subject to federal approval and oversight.

Federal agencies, including the Comisión Federal para la Protección contra Riesgos Sanitarios (COFEPRIS), the Ministry of Environment (SEMARNAT), and the Ministry of Agriculture (SADER), are charged with implementing and interpreting the decree. Any pending applications or permits will now be evaluated under the new legal framework.

A New Direction for Mexican Agriculture

The measure is also part of a broader government strategy outlined in the National Development Plan 2025–2030, which emphasises food sovereignty, agroecological transition, and sustainable resource use. Under this vision, Mexico seeks to reduce dependence on chemical-intensive agriculture and promote safer alternatives through education, technical support, and the promotion of organic and regenerative farming practices.

What Happens Next?

The decree mandates that within 180 days, the relevant ministries must revise existing regulatory frameworks to reflect the new prohibitions. Any further guidance on permitted substances, acceptable alternatives, or exceptions for critical use will be developed and published in the Diario Oficial de la Federación (DOF).

Additional Reporting

The Mexican government has introduced a federal programme, published in the Diario Oficial de la Federación (DOF), setting out a framework for coordinated action across priority sectors.

Background

Unlike decrees, which establish binding rules, a government programme serves as a strategic plan. It defines objectives, guiding principles, and institutional responsibilities. By publishing it in the DOF, authorities give the initiative official status and ensure transparency. The new programme reflects the administration’s commitment to strengthening governance and the protection of he environment through long-term planning, but lacks the authority that regulations or decrees have. Officials said it was designed to modernise public administration and improve accountability at both the federal and regional levels.

Key Measures

The programme outlines five major objectives for 2025–2030:

1. Biodiversity and ecosystems – conserve, protect, and use ecosystems sustainably, treating them as pillars for poverty reduction, social equality, and human rights, with special focus on indigenous and Afro-Mexican communities.

2. Restoration – restore priority ecosystems with interdisciplinary, cross-sector participation, ensuring justice and inclusion in environmental recovery.

3. Water security – guarantee the human right to water through sustainable management of rivers, aquifers, and watersheds, while protecting ecosystems.

4. Climate action – strengthen adaptation and low-carbon strategies, integrating pollution control to protect public health, ecosystems, and critical infrastructure.

5. Human-centred ecology – promote an ecological, humanistic policy with citizen participation, environmental culture, and access to justice supported by reliable information and a territorial perspective.

By combining these elements, the government seeks to build a coherent framework that avoids duplication of efforts and strengthens institutional efficiency.

Reactions

Businesses and civil society groups are expected to review the programme’s provisions closely. For some sectors, particularly those under strict regulatory oversight, the programme may open new opportunities while also imposing additional responsibilities.

Next Steps

The federal government will now focus on implementation. Agencies are expected to issue complementary guidelines, and funding mechanisms may be clarified in the months ahead. Officials stressed that the programme should be seen as a “living framework” one that may evolve as conditions change, but which provides a structured path toward Mexico’s development priorities.
