  • Reduction of GHG emissions compared to the base year 2017 by 71% (scopes 1 and 2) in line with the science-based target, but scope 3 emissions increased by 6%.
  • 100% CAPEX aligned with sustainable activities according to the European taxonomy.
  • Voluntary planting of 74,947 trees.
  • Recovery of 96.5% non-hazardous waste.
  • Approval of a new circular economy policy.


  • Reducing GHG emissions in line with the SBT target 2030 of 1.5°C reduction and offset GHG emissions in its direct operations.
  • Investing at least 95% of the CAPEX in sustainable activities according to the European taxonomy.
  • Voluntary planting of 117,500 trees.
  • Reducing the amount of waste sent to landfill in line with the 2025 target of reducing it by half.
  • Increasing the percentage of renewable resources in line with the 2025 target to double the consumption of recycled materials.
  • Reducing the use of surface water, groundwater, and municipal water in water-stressed areas by 11% compared to 2020.


The 44% reduction in the company’s scope 1 and 2 emissions in 2021 was due to the implementation of several decarbonisation projects. In addition, the waste to landfill has decreased thanks to a greater sludge recovery followed by the reuse of 100% of the legally recoverable slag and ashes generated in biomass plants.
