We recognize the importance of defining a strategic response to mitigate or offset the risks and impacts that climate change may have on our operations, value chain and our neighbor communities; therefore, we are contributing to national and international climate goals, including the Paris Agreement and United Nations Sustainable Development Goal 13: Climate Action.
We also expect that in the coming years, there will be an increase in the demand for products used in manufacturing clean technologies, products like copper.
Our response to climate change is built on four pillars:
Deliver products and services that support the transition to low carbon economies

At Grupo México, we work in sectors that are essential in the fight against climate change and in driving overall sustainable development.
Our Mining Division primarily produces copper, which is essential in the manufacturing of technological solutions that, collectively, have the potential to significantly reduce greenhouse gas emissions around the world. For example, electrically powered vehicles contain almost four times more copper than vehicles with internal combustion engines. Also, as a 100% recyclable metal that does not lose its properties when recycled. Copper facilitates the circular economy and helps preserve the environment.
Our Transportation and Infrastructure divisions provide rail freight transportation solutions that generate nearly four times less emissions than trucking, and we are developing clean and renewable energy, engineering and construction projects.
The transition to a sustainable economy demands solutions that drive decarbonization and resource efficiency. Sustainable revenue reflects a company’s commitment to inclusive growth and strengthens its competitive position in a resource-constrained world. Here are some illustrative examples about our Sustainable Revenues.
Reduce our carbon footprint

To transition to a low-carbon operation, we need to make substantial and sustained reductions in the greenhouse gas emissions produced by our various operations.
In this area, in 2022, we prepared a roadmap comprising the following areas:
Also in 2022, our renewable energy projects and energy efficiency prevented the emission of approximately 758,000 tons CO2e, projects like our El Retiro Wind Farm, and cogeneration projects and purchase hydroelectric power.
Additionally, our reforestation programs have contributed to reducing our carbon footprint, reforesting approximately 4,084 acres (1,653 hectares) with native plants.
Energy Management Program
In the Infrastructure Division, we established the Energy Efficiency department pursuing the optimization of our site’s consumption patterns. Our commitment to shaping a sustainable business environment nourishes the importance of the projects evaluated by this team in the consolidation of Grupo México’s Decarbonization Strategy.
We have developed and implemented an energy efficiency tool across several segments of our businesses. This tool aims to establish baselines on which we measure, verify, and report the progress of energy, cost, and emissions savings projects.
During 2024 and 2025, we expanded the use of our energy efficiency tool, which is now implemented across various segments of the Group like Charcas, Buenavista del Cobre and METCO operations. During the first half of 2025 this tool was implemented and started collecting information in Santa Bárbara, and in the second half of 2025 we will be identifying in which other operations the tool can be implemented.
We also improved the accuracy of our electricity consumption measurements by installing more advanced monitoring systems. These new systems allow us to track energy usage in each of the previous business units in greater detail, which is essential for measuring, verifying, and reporting progress in energy savings, cost reduction, and emissions mitigation. Thanks to this tool, we are also able to more clearly detect discrepancies between sites, and focus our efforts on areas with the greatest opportunities for improvement. Analyzing these measured values also allows us to standardize energy consumption KPIs, while information repositories are created within the tool to facilitate consultation from any interested area.
The Energy Efficiency team evaluates, proposes, and ensures the execution of projects in coordination with Maintenance, Operation, and Climate Change departments. As part of this work, we conducted energy audits at several facilities to identify areas for improvement. These audits provide us with clear roadmaps to implement concrete actions in the short, medium, and long term. Currently, we have begun prospecting initiatives in Real Estate, Electricity Generation, O&G Platforms, Highways, and Mining operations.
Energy efficiency solutions proposed for these lines of business include options for correcting low Power Factor, foster on-site renewable generation, reduce thermal load inefficiencies, equipment start-stop optimization, and awareness campaigns for the responsible use of our resources.
In addition, we actively participated in international forums on renewable energy, energy efficiency, and hydrogen. These engagements have allowed us to continue learning, share experiences, and stay current with global best practices. For example, in collaboration with the Mining Division, we developed a project to replace diesel with solar energy in our electro-winning (SX-EW) operations at La Caridad mine.
As a next step, we will incorporate the management of other energy resources, such as fossil fuels, to further contribute to our decarbonization goals. This approach will allow us to extend our Energy Management System across all Grupo México operations.
Increase the resilience of our operations and neighbor communities to the effects of climate change

One of the key actions to strengthen the resilience of the Grupo México business model is to identify and manage the risks and opportunities related to climate change by analyzing climate scenarios, which we have been doing since 2020. As a result, we are incorporating factors related to climate change into our business decisions involving either risks (e.g., carbon taxes, increased costs related to climate management, physical impacts on operations) or opportunities (e.g., increased demand for copper, substitution of fossil fuels, implementation of low or zero emission technologies).
The scenarios were selected based on the 2017 guidelines of the Task Force on Climate-Related Financial Disclosures (TCFD).
We have also been building on recent efforts to understand, prevent and better address the risks associated with water management, both at our facilities and in the watersheds where we operate. In this regard, we regularly review and update our inventory of water-related risks, and also our plans to prevent and address these issues.
As a result, we have invested US$193.00 million in water management projects and others to mitigate incidents that could result from extreme rainfall. For example, we have been working on upgrading the water distribution network in cities near our operations, and we have designed, built and put into operation water treatment plants to optimize this resource. Additionally, our Buenavista del Cobre mine has designed a tailings storage facility that will support an extreme storm that would produce 20 million cubic meters (over 5 billion gallons) of water, which will prevent flooding and impacts downstream.
In 2023, we will be revising our analysis to consider the most recent scenarios recommended by the Intergovernmental Panel on Climate Change (IPCC) in their report (AR6).
The results of this new analysis will inform the calculations of potential financial impacts on our operations and our value chain in the medium and long term, and will also ensure we are meeting the increased market demand and, particularly, the new requirements expected from the Securities and Exchange Commission (SEC) on climate disclosures.

This Department regularly reports to the Audit and Company Practices Committee and also to the Executive Vice-President. In addition, Grupo Mexico has a Sustainable Development Committee at the Board Level of Southern Copper Corporation (SCC), which is made up of independent board members. The SCC Executive Vice-President, who is also the Executive Vice-President of Grupo México participates in this Committee. The Committee supervises the implementation of our climate change strategy, including the management of risks and opportunities associated with climate change and the transition progress.
During the first half of 2024, Chapter Zero held an information session aimed at the Directors of Grupo México and Southern Copper Corporation, to introduce the main concepts of climate governance based on the World Economic Forum´s eight principles for the effective implementation of climate governance. Additionally, climate risks and opportunities of mining, infrastructure and transportation industries were presented, as well as the fundamental role that copper represents for the energy transition.
Chapter Zero is a section of the Climate Governance Initiative and the World Economic Forum, which contributes to generating, facilitating and disseminating information, tools and good practices that will exclusively allow company directors to develop skills and capabilities necessary to manage climate risks, and at the same time, develop strategies that will contribute to moving towards a sustainable and carbon-neutral economy by 2050.
