27.1 Disclosures of disbursements related to the environment

The Company is currently operating under an Environmental Management System (EMS) that has allowed it to strengthen its environmental performance through the effective application of the Company’s Sustainable Development Policy. In 2020, the company announced an ambitious Sustainable Development Plan, which establishes specific aspirations internal goals that seek to make SQM a leader in sustainability around the world. The main goals proposed are:

i) A 65% reduction in the use of fresh water by the year 2040 and 40% by 2030, with respect to BAU (Business as usual).

ii) A 50% reduction in brine extraction from the Salar de Atacama by 2030, starting with 20% by November 2020, compared to the environmental permit.

iii) Ensure that all our products are carbon neutral by 2040 and in the case of lithium and potassium chloride, this goal is for 2030.

iv) Stimulate more and better instances for dialog with the communities near the operations.

During the year 2025 we have been making progress with each of these aspirations, starting with quarterly management of sustainability indicators and monitoring them on a quarterly basis. This has helped us to identify initiatives that help us to achieve these aspirations.

The Company carries out environmental follow-up and monitoring plans based on specialized scientific studies. Follow-up on relevant variables defined for each project enables the Company to verify the status, for example, of vegetation, flora, fauna and aquatic life in the ecosystems to protect. Follow-up plans are supported by a broad control network that includes monitoring points such as meteorological stations and wells, satellite images, plots for recording the status of vegetation and fauna, etc. The activities comprised in these plans are reported regularly to authorities based on the Company’s commitments made through resolutions that approve different SQM projects. For the specific case of the Salar de Atacama, the Company has implemented an online platform (www.sqmsenlinea.com), which enables any person to access all the environmental information compiled by the Company in keeping with its commitments
