Mexico Unveils Ambitious New Climate Commitment at COP30 with 2035 Emissions Cap

Mexico Presents Landmark Climate Plan at COP30

Belém, Brazil – Mexico has officially unveiled its ambitious new Nationally Determined Contribution (NDC 3.0) at the 30th United Nations Climate Change Conference (COP30), currently underway in Belém, Brazil, from November 10 to 21, 2025. The updated climate plan marks a significant step in the country's environmental policy, introducing for the first time an absolute emissions cap for 2035 that encompasses all greenhouse gases and economic sectors.

Alicia Bárcena, Mexico's Minister of Environment and Natural Resources, presented the NDC 3.0, emphasizing its role as a comprehensive roadmap for accelerated decarbonization and sustainable development. The plan was developed through a participatory process, guided by the Escazú Agreement, and draws on scientific evidence.

Absolute Emissions Cap and Reduction Targets

A cornerstone of Mexico's NDC 3.0 is the commitment to absolute emissions targets. By 2035, the country aims to cap its emissions between 364 and 404 million metric tons of CO₂ equivalent (MtCO₂e) under an unconditional scenario, financed with domestic resources. With international support, this target could be further reduced to between 332 and 363 MtCO₂e. These figures represent a substantial reduction of more than 50% compared to current trajectories or a business-as-usual scenario, positioning Mexico among a select group of developing nations to establish fixed carbon ceilings within defined timeframes.

The new commitment also reaffirms Mexico's long-term objective of achieving net-zero emissions by mid-century.

Comprehensive Sectoral Coverage and Strategic Pillars

Mexico's NDC 3.0 integrates climate goals into a new economic strategy, 'Plan México,' targeting key sectors for decarbonization. These include:

• Transport
• Electricity generation
• Industry
• Agriculture and livestock
• Waste management
• Oil and gas
• Construction

The plan is structured around five interconnected components: mitigation, adaptation, loss and damage, means of implementation, and enabling conditions and cross-cutting themes. Notably, the NDC 3.0 introduces a new national security component, acknowledging climate change as a potential driver of social and environmental conflict.

Minister Bárcena highlighted that the initiative aims to drive technological innovation, promote circular economy principles, and curb methane emissions, recognized as one of the most potent greenhouse gases. On adaptation, Mexico plans to publish its first National Adaptation Policy in 2026, focusing on critical areas such as food and energy security, biodiversity conservation, water management, and the protection of infrastructure.
