Management of environmental issues

Our performance focuses on a renewable future. That is why we have been following the path of sustainability for years, with clear and significant objectives for the planet.

The management of environmental issues considers water resources, energy sources, atmospheric emissions, and solid waste. We operate in compliance with laws and regulations and with parameters for the control of indicators, some of which are more stringent than those stipulated by legislation.

Our role in the climate change agenda

Climate change is a material theme in the Klabin 2030 Agenda. The constant reduction of greenhouse gas (GHG) emissions is one of the items of Klabin’s Sustainability Policy, which guides the company’s actions and ensures it adheres to important external initiatives, reinforcing its commitment to the theme.

Since 2019, we have participated in the UN’s global campaign ‘Business Ambition for -1.50 C – Our Only Future,’ helping to restrict the rise in temperature on the planet to 1.50 C. The initiative requires commitment through actions based on scientific factors, which led us to submit our greenhouse gas emission reduction targets to the Science Based Target (SBT).

In 2020, we became a TCFD Supporter, in public support for the Financial Stability Board’s recommendations on climate risk and opportunity management, thereby improving the company’s transparency and communications on the subject.

In addition to being the first Brazilian company to commit to drawing up targets for the reduction of emissions based on science, in alignment with the Science Based Targets initiative (SBTi), and being the first company in the pulp and paper sector in Latin America to have its goals approved by the SBTi, in 2021 we structured a campaign in partnership with the Brazil Network – UN Global Compact – to engage companies and society in projects to reduce and neutralize carbon emissions by 2050. In addition to making this commitment, we contribute to mobilizing other companies and people to join the movement.

Initiatives that reinforce our commitment

How we manage the theme

Since 1993, we have carried out a GHG inventory, verified by a third party. The material is available for consultation in the Public Emissions Registry, which is a transparent, fast, and simple dissemination platform for corporate emission inventories by organizations participating in the Brazilian GHG Protocol Program. We have a detailed matrix of climate opportunities and risks, which includes the internal mapping of impacts already occurring due to climate events, as well as notes from the Climate Conference (COP) and the Intergovernmental Panel on Climate Change (IPCC).

We have two researchers who specialize in ecophysiology and climatology, focused on analyzing climate change that can influence our forest planning.

In 2020, we developed the Marginal Abatement Cost Curve (MACC) tool, which prioritizes what technologies Klabin has in its strategic climate change roadmap aimed at reducing the use of fossil fuels, taking into account a market with carbon pricing.

What we have done

In 2020, we installed 32 weather forecast and climate monitoring stations in our operational area in Parana state. We also did a study to integrate our information and actions in the climate risk and opportunity agenda to communicate how we implement the TCFD recommendations. 

We also began development of an app to indicate to forestry operations drivers in Parana the best route to take in the forest, saving fuel or preventing nuisance for communities.

Since 2019, we have used the Salvador device in trucks, which helps reduce diesel consumption and gas emissions. 

See the ESG Panel indicators 305-1, 305-2, 305-3 and 305-4 and other indicators related to Climate Change.

Greenhouse gas (GHG) management)

Technology has become an ally for the company in reducing GHG emissions. In forestry operations in Parana, for example, truck drivers use the Salvador device in vehicles, which helps reduce diesel consumption and gas emissions. We also began development of an app to indicate the best route for forestry operations drivers in Parana to take, saving fuel or preventing nuisance for communities.

Even with a 2% increase in production from 2019 to 2020, Klabin reduced the specific emissions of scopes 1 and 2 from 185 kg CO2eq/t to 165 kg CO2eq/t*. Absolute emissions of scope 1 decreased by 1%, and absolute emissions of scope 2 decreased by 19% based on location, and 23% based on choice of purchase for the same period.

*Since 2020, Klabin started to consider Scope 2 emissions based on the purchase choice methodology.

In 2021, our target was approved by the Science Based Target initiative (SBTi): we committed to reducing GHG emissions (scopes 1 and 2) per ton of pulp, paper and packaging by 25% by 2025 and by 49% by 2035, taking 2019 as the base year. The limit of the targets includes biogenic emissions and removals of bioenergy raw materials.

Since 2003, we have reduced more than 60% of specific scope 1 and 2 emissions in our operations.

See the ESG Panel GRI indicators and others related to emissions.

For a renewable energy matrix

Energy efficiency is one of our guidelines for climate change management. We strive to progressively increase the renewable energy matrix produced from biomass and black liquor.

 Currently, 90%of our energy matrix is composed of renewable sources: 57% black liquor, 32% biomass and 1% other sources.

The showcase is the Puma Unit, which uses biomass for power generation, and all surplus energy is sold. In 2020, 1,007,411.83 MWh were sold to the Brazilian grid. Our professionals look for opportunities to reduce energy, steam and compressed air consumption, and to eliminate waste.

With ISO 50001:2018 certification (attesting to good practices in energy management), the Puma Unit is regularly subject to internal and external audits of its Energy Management system.


Among our goals for energy use for 2030 are the reduction of the share of fossil fuels to ensure an energy matrix that is at least 92% renewable, and the purchase of 100% certified energy from renewable sources.

Renewable energy

The Puma Unit has the capacity to generate 270 MW of clean energy from the steam produced by black liquor and biomass boilers, making the unit self-sufficient in energy and supplying up to 120 MW to the national grid, cleaning the Brazilian energy matrix.

In the Puma II Project, we apply the highest level of technology to ensure the continuity of self-sufficiency in energy, through the processes of optimization, automation, and total use of biomass. The installation of a gasification plant will allow wood to be transformed into gas for use as the main fuel in one of the lime ovens, replacing fuel oil.

Focus on reducing water consumption

Water is one of the most important inputs for our processes, especially in pulp and paper production. All of our units operate in accordance with the environmental laws and regulations in force, at municipal, state, and federal levels. In addition, we focus on reducing consumption and seeking continuous improvement in all processes, valuing the conservation of natural resources and increasing water reuse.

We are part of the Tibagi River Basin Committee in Parana, and the Canoas River Basin Committee in Santa Catarina. We also participate in other committees where we have mills. Representatives of the company actively participate in discussions on the use of water, in which water collection mechanisms and resources are planned.

Through the WRI Aqueduct tool, we measure the ratio between total annual water withdrawals and the available annual renewable supply. Indexes higher than 20% indicate that there is competition among users – that is, they are areas of water stress. In 2020, four Klabin units were in areas considered to be under water stress: two in Jundiai (Sao Paulo state) – the Industrial District and Tijuco Preto – the Goiana Unit (Pernambuco state) and the Horizonte Unit (Ceara state). Together, they captured 928.86 megaliters of water in the year, representing 0.9% of the total water withdrawn by Klabin, a reduction of 23% on 2019.


Among the Klabin 2030 Agenda goals for water use are the following: to reduce the specific consumption of industrial water by 20%; to carry out 100% of forest operations under our management using hydro-solidarity management; to have initiatives to increase territorial water security in 100% of the places we operate in. 

Hydro-solidarity management is a pioneering initiative by Klabin to identify the best forest management practices to extinguish or minimize impacts in micro basins. Based on scientific studies, it considers, among other factors, the planting of pine or eucalyptus with local water supply and the availability of the resource on small properties.

We capture 23.7 m³ of water per ton product (surface water, groundwater, and third-party water).

Management of impacts related to water disposal

Effluent disposal standards are based on municipal, state, and federal laws for each unit. In addition, we compare our results with the IFC/IPPC indicators, which are a reference in the pulp and paper sector. To determine the maximum release limits, the responsible environmental agency requests a study of water dispersion and self-purification of the water body to evaluate and determine the limits that do not generate changes in the quality and volume of the water body.

 Effluent disposal

The plants follow the limits established by the laws in force in each state and country for reference and monitoring of effluents. Parameters such as Biochemical Oxygen Demand (BOD5) and BOD5 removal efficiency are priorities. In pulp and paper mills, the concentrations of Chemical Oxygen Demand (COD) and phosphorus in effluents are also of great importance. Indices are often compared to global benchmarks, such as IPPC and IFC.

In 2020, we reduced the volume of treated effluent released by 3%. In the units in areas under water stress, the treated effluent released was reduced by 43%.

Treated effluent

One hundred percent of effluent is treated at Effluent Treatment Plants before returning to water bodies. The treatment is monitored internally and by a third party, evidencing compliance with all the legal requirements. Periodically, the units undergo internal and external audits for evaluation of the Management System, including the water and effluent system. In several Klabin units, goals related to water issues are linked to the Profit-Sharing Program.

Inclusion of a third stage in treatment at the Puma Unit ensures emissions that are easily absorbable by the water body. In addition, the discharge point is before the capture point.

See the ESG Panel indicators GRI 303-1, 303-3, 303-5 and others related to the material theme Water use.

Waste management

Our Sustainability Policy includes pollution prevention by reducing the impacts of solid waste generation; the search for the most efficient technologies and solutions; the guidance of the SDGs; and compliance with legislation and standards applicable to the product, the environment, health and safety. Environmental management is also based on ISO 14001, which most of our units are certified by. The KSDGs target for waste is to eliminate the disposal of industrial waste in landfills.

In 2020, Klabin took an important step in pursuit of the KSDGs target to eliminate industrial waste sent to landfills by 2030. We reused 98.3% of our solid waste.
