Metsä Board Publishes Sustainability Review 2025 and Green Debt Report 2025, Highlighting Strong Progress in Climate Action

Metsä Board Oyj, a leading European producer of premium fresh fibre paperboards, today announced the publication of its Sustainability Review 2025 and Green Debt Report 2025, underscoring the company’s continued commitment to sustainability and measurable climate progress.

The Sustainability Review 2025 provides a concise overview of Metsä Board’s key sustainability priorities and its progress toward 2030 targets. The report emphasizes the integration of environmental and social considerations into the company’s operations, value creation, and customer solutions.

Metsä Board’s sustainability strategy focuses on four key areas:

• Climate action

• Environmental impacts of products

• Biodiversity enhancement

• Safety across operations and the value chain

Over recent years, Metsä Board has made significant investments in its mills to enhance product quality, improve resource efficiency, and reduce emissions. As a result, the company has achieved a 79% reduction in fossil-based Scope 1 and 2 CO₂ emissions from 2018 to 2025, surpassing the Paris Agreement-aligned 1.5°C target ahead of schedule.

Additionally, 93% of the energy used in production is now fossil-free, reinforcing the company’s position as a sustainability leader in the paperboard industry. Combined with lightweight product design, these advancements enable customers to reduce packaging-related carbon footprints and meet their own sustainability goals.

“Our sustained investments and focused actions have enabled us to significantly cut emissions while improving efficiency and product performance,” said Esa Kaikkonen, CEO of Metsä Board. “We are proud to have exceeded our 2030 climate ambition early and remain committed to driving further positive impact across our value chain.”

The Sustainability Review complements the company’s Sustainability Statement, published as part of the Annual Review 2025, which provides detailed disclosures in line with the Corporate Sustainability Reporting Directive (CSRD) and European Sustainability Reporting Standards (ESRS).

In addition, Metsä Board released its Green Debt Report 2025, detailing the allocation and impact of its EUR 200 million green bond issued in 2025. The full proceeds were allocated to refinancing renewal investments at the Husum pulp mill in Sweden, supporting key areas within Metsä Group’s Green Finance Framework:

• Renewable and fossil-free energy

• Waste and side stream management

• Pollution control

The report has undergone a post-issuance review by KPMG Oy Ab, with allocation and impact indicators subject to limited assurance.
