KODS 2030

Lead the reintroduction of at least two species proven to be locally extinct and promote population reinforcement of four other threatened species
 

Black-fronted Piping-Guan  (Aburria jacutinga)
The Black-fronted Piping-Guan  (Aburria jacutinga), which was proven extinct in Paraná, provides the ecosystem service of seed dispersal, contributing to the restoration of natural forests. In 2025, monitoring campaigns were conducted for the Black-fronted Piping-Guan (Aburria jacutinga), using linear transect methods, direct observation, playback, camera traps, and citizen science, assessing its capacity for survival, dispersal, and formation of reproductive pairs. The initiative continues the work of reintroducing the species that began in 2022, when 30 individuals were released.

Klabin is part of the technical advisory group for the Jacutinga Population Management Plan. This is one of the actions of the National Action Plan for the Conservation of Galliform Birds, whose main premise is to maintain a safe population of the species under human care, which will enable the continuity of reintroduction projects such as this one.

Vinaceous-breasted Parrot (Amazona vinacea)
The Vinaceous-breasted Parro(Amazona vinacea) is a species endemic to the Atlantic Forest with great ecological relevance for the region, providing the ecosystem service of seed dispersal. In February 2025, three individuals of the species were released after completing all the stages of the adaptation process. Since their release, the animals have remained in the vicinity of the Klabin Ecological Park.

KODS 2030
 

Have 100% of wildlife–vehicle collision hotspots mapped and with initiatives to reduce accidents.
 

In 2025, Klabin made progress in systematizing the monitoring of collisions with wildlife on roads in Paraná. From 2021 to December 2025, 46 monitoring campaigns were conducted. The main actions were:

• Cumulative sampling of 8,000 km since the beginning of the project;
• Forwarding of biological material for scientific research;
• Consultative participation in road projects under study, with data and recommendations.

Operational units in environmental protection areas and areas of high biodiversity value outside environmental protection areas 

Klabin is a forest-based Company with responsible management and a commitment to biodiversity. Accordingly, five of the 23 targets of Klabin’s Sustainable Development Goals are focused on the preservation and conservation of flora and fauna (https://klabin.com.br/sustentabilidade/agenda-klabin-2030). 

The quality of its business is directly linked to conserving biodiversity and the ecosystem services it provides. Consequently, Klabin employs mosaic planting, interspersing pine and eucalyptus forests with expanses of native trees, which account for almost half of its forestlands. This practice creates ecological corridors and protects habitats. The Company also monitors roadkill on 8,000 km of roads near its operations and develops technologies aimed at controlling invasive species that can affect local biodiversity balance. In addition, it has a zero-deforestation policy and a policy of zero conversion of native forests into tree plantations. 

The Company maintains more than 18,000 hectares of High Conservation Value Areas and Private Nature Reserves on its properties. For example, Fazenda das Nascentes, a property that forms part of the Serra da Farofa Private Nature Reserve in Santa Catarina, has FSC® certifications for three ecosystem services: biodiversity conservation (ES1), carbon sequestration and storage (ES2), and watershed services (ES3). 

This set of actions is linked to Klabin’s sustainable finance strategy, based on an approach to debt that is tied to environmental commitments and biodiversity targets. 

All the Company’s forests are certified under the FSC® and PEFC standards. 

External commitments 

Klabin is a signatory to commitments such as CDP, the Brazilian initiative “Empresas pelo Clima” (“Companies for Climate”), the GHG Protocol, The Forests Dialogue and several international agreements renewed annually through forest management certifications. The CDP Forests Program has recognized the Company as an “A-level” leader, reflecting its commitment to zero deforestation.

Nature Interpretation Center

Opened in March 2019, the Nature Interpretation Center, located in the Serra da Farofa Private Nature Reserve in Santa Catarina, reflects Klabin’s commitment to scientific research and biodiversity conservation. The facility, built in alignment with sustainability principles to minimize its impact on the local ecosystem, can house up to 40 researchers and offers heated dormitories, a cafeteria and study areas. [1][3] 

In 2024, as it celebrated its fifth anniversary, the center reaffirmed its strategic role in supporting applied science in the areas of conservation, forestry and forest management. The Private Nature Reserve is home to around 1,000 native species in 5,000 hectares of Atlantic Forest and high-altitude grasslands. 

Klabin conducts research to assess and control pests and diseases, focusing on biological solutions. Since 2020, it has been developing a biological-based product to control leafcutter ants. 

Forest innovation and technology transfer in forest management are priorities. Klabin evaluates biotic and abiotic factors to determine the allocation of pine and eucalyptus, seeking productivity gains in its plantations in the regions where it has forest expansion projects. The Company also has specialists dedicated to the areas of genetic improvement of eucalyptus and pine, biotechnology and cloning, nutrition and silviculture, ecophysiology, forest protection and wood quality. Additionally, Klabin monitors research on genetically modified species and new biotechnological processes, although it does not use them, maintaining compliance with forest certifications.
