Although Mexico only contributes 1.3 percent of global carbon emissions, the Government of Claudia Sheinbaum presented the Nationally Determined Contribution (NDC 3.0).
Mexico City, November 19, (However).- The Government of Mexico pledged on Tuesday to contribute to the mitigation of between 364 and 404 million tons of carbon equivalent in net emissions for 2035 unconditional. Within the framework of the United Nations Conference on Climate Change in Brazil (COP30), a commitment was also made to mitigate between 332 and 363 million tons of this chemical element on a conditional basis.
The new Nationally Determined Contribution (NDC 3.0) was presented by the Secretary of the Environment and Natural Resources (Semarnat), Alicia Barcenawho reaffirmed the commitment of the Government of the President Claudia Sheinbaumas well as subsequent administrations, despite the fact that Mexico only contributes 1.3 percent of global carbon emissions.
“In this COP of truth, what we technically call loss and damage here are, in real life, girls, boys and families who lose everything in a matter of minutes, the product of a climate exacerbated by a predatory development model. These are not figures, they are absences, which is why our NDC incorporates loss and damage as a component because mitigating and adapting is no longer enough when vulnerability grows faster than our capacity to respond,” said Bárcena.

In this sense, the head of Semarnat explained that NDC 3.0 is aligned with the President’s Plan Mexico, which is why it contemplates a fair, energetic and social transition that includes new generation projects to decarbonize the economy, promote the circular economy and meet the goal of conserving 30 percent of the territory by 2030, as well as reforesting and protecting jungles, forests and mangroves.
In this list of ideas, Alicia Bárcena pointed out that the new climate goal incorporates the gender and human rights perspective, since it was the result of a participatory process in which communities, youth, women, academia, the productive sector and indigenous peoples were consulted.
The official also announced the creation of the Great Mayan Forest Biocultural Corridor, whose project seeks to unite Mexico, Guatemala and Belize, in order to protect 5.7 million hectares of the second largest tropical forest in America, which also contains the most important freshwater reserve in Mesoamerica.
For its part, the National Commission of Protected Natural Areas (Conanp), presented the initiatives MEx30x30, to guarantee the conservation of 30% of the Mexican territory in 2030, and ACCION (Sustainable Communities for Climate Action in the Yucatan Peninsula), which seek to close Mexico’s financial gap towards 2030 in terms of biodiversity.
Both measures will be executed in alliance with the Mexican Fund for Nature Conservation (FMCN), and have the support of the Global Environment Fund (GEF) and the Green Climate Fund (GCF), as explained by the head of Conanp, Pedro Álvarez-Icaza.
