Net Emissions
Reduction

Climate change is one of the main environmental challenges today, associated with the increasing frequency of extreme weather events that can pose risk to health and well-being.

One of the main causes of this phenomenon is related to the emission of gases used in industrial processes and refrigeration systems, which contribute to global warming and reduce the atmosphere’s ability to protect the Earth from solar radiation (greenhouse effect).

At CYDSA, the priority and objective related to the reduction of net emissions of these greenhouse gases is presented below:

Objectives and Metrics

Reduce the Intensity of Scope 1 and 2 Emissions of the CYDSA Group to a range between 0.65 and 0.85 tCO2e/t produced by 2030, which is equivalent to a reduction in the indicator of between 50% and 62% compared to the level of 1.7 tCO2e/t produced in 2018.


The performance of the objective, measured in Scope 1 and Scope 2 greenhouse gas emissions (CO₂ equivalent), is presented below.

GHG emissions intensity (thousand tons CO2e / thousand tons produced) 2018 2023 2024 2025 Variation % 2024 vs 2025
Direct GHG emissions intensity (Scope 1) 1.47 0.33 0.30 0.20 -33.3%
Indirect GHG emissions intensity from energy generation (Scope 2) 0.23 0.29 0.31 0.29 -6.6%
Total GHG emissions intensity (Scopes 1 and 2) 1.69 0.62 0.61 0.49 -19.7%
Reduction in GHG emissions intensity (vs. base year 2018) N/A -63.6% -63.9% -71.% -7.1pp

To achieve this, CYDSA has implemented actions to reduce greenhouse gas emissions, including:

  • The adoption of cleaner technologies for chlor-alkali production.
  • The incorporation of argon plasma arc technology for the control and destruction of fluorinated gases.

These measures contribute to strengthening the long-term sustainability of the business.

Circular Economy

The circular economy is a model that seeks to maximize the use of resources and reduce waste, promoting a more sustainable economic system.

For CYDSA, water is a critical resource for production; therefore, two objectives have been established for its efficient use, related to:

  1. Water recirculation.
  2. Extraction of wastewater or treated water.

In the case of water recirculation, the objective is presented below:

Objectives and Metrics

Increase the Volume of Recirculated Water of the CYDSA Group to a range between 2.40 and 2.80 million m3 by 2030, which corresponds to an increase in the indicator of between 98% and 131% compared to the level of 1.21 million m3 in 2018.

The performance of the objective, measured in thousands of cubic meters, is presented below:

Volumen iof Recirculated Water

2018 (base year) 2023 2024 2025 Variation % 2024-2025 Variation % 2018-2025
1,208 1,920 2,239 2,663 +19% +121%

The performance above has been achieved due to initiatives implemented at several plants related to water recovery for production processes.

Regarding the volume of wastewater extraction, the objective is presented below:

Objectives and Metrics

Increase the Volume of Wastewater Extracted by the CYDSA Group to a range of between 0.85 and 1.40 million m3 by 2030, which corresponds to an increase in the indicator of between 46% and 139% compared to the level of 0.58 million m3 in 2018.


The performance of the objective, measured in thousands of cubic meters, is presented below: 

Extraction volume of blackwater or treated water

2018 (base year) 2023 2024 2025 Variation % 2024-2025 Variation % 2018-2025
585 772 519 525 1% -10%

The above has been achieved using wastewater or treated water for production processes in plants where there is high water stress.
