Caustic soda is an important base chemical, of which more than nine million tons are needed per year in Europe alone. Westlake Vinnolit offers certified climate-friendly caustic soda utilizing renewable energy Guarantees of Origin (GOs). The CO2 footprint of this low-carbon caustic soda from the Gendorf and Knapsack (Hürth) sites – which is introduced to the market under the brand name GreenVin® – is reduced by more than 50% compared to conventional Westlake Vinnolit caustic soda. The CO2 footprint taken as a basis was calculated by sustainable AG in accordance with the ISO 14067 standard. Review and certification are carried out by TÜV Rheinland.

We pay special attention to the quality of the renewable energy certificates through recognized additional labels. These guarantee the purchase of 100% renewable energy, excluding publicly subsidized plants, as well as the application of additional ecological criteria, such as the promotion of new green power plants as well as innovative energy transition projects.
