In 2021, Klabin emitted 155 kg CO2eq per ton produced, a reduction of 6% compared to 2020 and the equivalent of 10.3% of the target agreed with the SBTi, having 2019 as base year.
-
Total emissions (direct and indirect) reached 1.3 million tons of CO2eq, 7% above 2020, mainly due to the units acquired from IP and the start-up of Puma II.
-
Even so, considering the 17% increase in production in the period, the energy intensity decreased by 8%.
-
This result is mainly due to the 44% reduction in the intensity of scope 2 emissions as a result of the issuance of renewable energy certificates (I-RECs) from the surplus power generated by the Puma Unit.
-
4.9 millions tons of CO2eq was the net capture from the atmosphere in the period.
Klabin's carbon balance is positive, which means the Company captures more carbon dioxide from the atmosphere than it emits in its operations.

SEE GLOSSARYIncreasingly renewable matrix
Klabin has been working to increase its energy production capacity from biomass and black liquor, progressively increasing its renewable energy matrix.
Today, 89.5% of the Company's energy matrix comes from renewable fuels, and the goal is to reach 92% by 2030, in addition to attaining 100% purchase of certified energy from renewable sources.
In search of solutions for increasingly sustainable production, the Company's researchers study the implementation of low-carbon technologies, such as tall oil, generated from soap (byproduct of the paper making process), and bio-oil obtained from residues of wood, branches and leaves (post-harvest). Both can significantly contribute to the company achieving its goals related to the control of pollutant emissions and the use of clean energy.
Klabin also uses other renewable fuels, obtained within its production processes, such as methanol, turpentine, tar from tall oil and hydrogen. The latter is obtained directly from a satellite chemical production unit in the Puma Unit, in volumes of about 2,000 tons/year, which equates to the replacement of 4,000 tons of fuel oil.
An example of a project already implemented is the case of the biomass gasification plant at the Puma Unit, which has the potential to reduce more than 65,000 tons of CO2eq from the reduction of 20,000 tons of fuel oil. This project came online in March 2022, marking the beginning of a new cycle to achieve science-based targets.
Self-sufficiency at the Puma Unit
The Puma Unit, in Paraná, uses biomass for energy generation and sells the surplus. An Internal Energy Conservation Committee seeks opportunities to reduce energy, steam and compressed air consumption at the plant, in addition to eliminating waste.
In 2021, a third turbogenerator in the unit came online, integrated with two others already in operation. Together, they now produce enough power to supply the plant's electricity demand for two pulp machines, one kraftliner machine and, in the future, one paperboard machine (MP28), including a high-yield pulp mill. Energy is also used by partners in the production of Oxygen and Sodium Chlorate, used in bleaching plants. The generation surplus is transmitted to the National Interconnected System, which operationalizes the country's production and distribution of electricity.
With this new turbogenerator in operation, Klabin is contributing even more to the production of clean and sustainable electricity, which is fundamental especially when the reservoir levels of the hydroelectric plants are low, which has been occurring.
In the Puma II project, the highest level of technology available is applied to ensure the continuity of self-sufficiency in energy, which is done through the processes of optimization, automation and total use of biomass and byproducts. The installation of a gasification plant allows wood to be transformed into synthesis gas for use as the main fuel in one of the lime ovens in place of fuel oil.
820.490 MWh*
were delivered to the Brazilian Electric System by the Puma Unit in 2021.
90 MWh/h
is the estimated power that will be made available with the third turbogenerator.
250,000
homes can be supplied with this amount of surplus energy.
- *1,074,564 MWh if the settlement of the Electric Energy Commercialization Chamber (CCEE) is considered.
