OTHER ATMOSPHERIC EMISSIONS
Our industrial processes generate different atmospheric emissions, which can adversely affect the environment and people. For this reason, we focus on measuring the atmospheric emissions produced by our operations, comply with the regulations applied to each of our plants, and have abatement systems. At the same time, we are transparent about our most relevant emissions, such as Particulate Matter (PM), Nitrous Oxide (NOx), and Sulfur Dioxide (SO2).

There is a green tax on emissions from fixed sources, which is part of the regulations established in Chile’s tax reform in 2014 and began to be applied in 2017, and in Mexico since 2023. The above establishes a charge to organizations that emit Particulate Matter (PM), Nitrogen Oxide (NOx), Sulfur Dioxide (SO2), and Carbon Dioxide (CO2) into the air, produced by operations of companies whose fixed sources, consisting of boilers or turbines, individually or as a whole add up to a power greater than or equal to 50 MWt.

In 2025, CMPC paid USD 4.79 million in environmental "green" taxes in Chile and Mexico, representing a 12.7% reduction compared with 2024. The decrease was primarily driven by lower green tax payments in the Cellulose and Biopackaging businesses. The company continued to strengthen its tax governance framework through its Tax Compliance Strategy, aligned with OECD principles, and was recognized for a second consecutive year by the Pontificia Universidad Católica de Valparaíso (PUCV) in its “Tax Sustainability Indicators” study of IPSA-listed companies, highlighting its practices in tax transparency, governance, and responsible tax compliance. Nearly all green taxes were associated with operations in Chile, which remains the company's primary jurisdiction for environmental taxation.
