NEW YORK, May 26, 2026 (GLOBE NEWSWIRE) -- Mercer International Inc. ("Mercer" or the "Company") (NASDAQ:MERC), a global forest products company, today released its 2025 Sustainability Report, themed "Resilience in Action." The report outlines, among other things, the Company's progress towards its 2030 sustainability goals.

Juan Carlos Bueno, President and CEO, stated:

"The global economy is being rebuilt around renewable and lower-carbon systems, and forest products play an important role in that shift. Responsibly managed forests sequester carbon, and the products we make store carbon during their lifecycle while displacing fossil-based alternatives across the industries we supply. Sustainability is not a cost center; it is the most reliable investment we can make in our long-term competitiveness and resilience."

Bill Adams, Chief Sustainability Officer and Senior Vice President, Canadian Pulp Operations, added:

"At Mercer, our sustainability focus going forward is on the execution of our 2030 sustainability goals. In doing so, we will strive for measurable progress and operational results that enhance value for our company. We believe that the combination of operational discipline, science-based analysis, and regulatory readiness is what can turn commitments into a meaningful competitive advantage."

2025 sustainability highlights include:

Climate & Emissions

85% of energy used across global operations was generated from renewable sources, advancing toward our 90% target by 2030.
Achieved an 11% reduction company-wide in Scope 1 GHG emissions intensity through operational efficiency and reliability improvements.

Advanced Mercer's e-mobility strategy by commissioning two electric chip trucks at Mercer Holz and an electric forklift at Mercer Timber Products to reduce fossil fuel reliance in daily logistics.
