For decades, our products have helped to reduce greenhouse gas emissions. We offer CO₂-optimised products and, as a company, are constantly improving our environmental performance. Our aim: to continuously reduce our carbon footprint and prevent the demolition of buildings through long-lasting concrete repair.
At Sto, we communicate actively and openly about our commitment and our contributions to climate protection at the level of individual products and the company as a whole. This helps us to increase awareness of greenhouse gas emissions and to make a contribution to reducing them. We also strive to raise awareness in dialogue with politicians and the public, for example through our participation in associations and collectives, and at conferences, seminars, and other events.

Our experience shows: Building with conscience is possible. For example, our products help to significantly extend the service life of reinforced concrete structures. Every tonne of cement saved avoids the emission of one tonne of carbon dioxide. In addition, the use of natural resources is reduced to a minimum. This is how we bring honest sustainability to the construction industry. To preserve our planet - for this and future generations.

Maintaining health and creating a feel-good atmosphere - in all areas of life. This goal has driven us for more than 25 years. With a great deal of passion and experience, we develop functional coatings for a positive, unpolluted indoor climate. Our StoCryl BF 700 floor paint meets the high standards required for building with conscience.

Singapore Green Building Council: StoPox WL 113 achieves best possible rating (Leader)
StoPox WL 113 was tested by the Green Building Council in Singapore according to the criteria of the "Singapore Green Building Product Certification Scheme" and received the best possible rating.
In this test, the VOC emissions and the content of heavy metals are tested in order to be able to make a statement on the ecology of the product, similar to LEEDS and DGNB. Green Building is categorised as "Good", "Very Good", "Excellent" and "Leader".
StoPox WL 113 has been categorised as a Leader, and it is a Leader in the truest sense of the word.

For Sto, climate protection also means considering alternative raw materials in order to reduce CO₂ emissions. We optimise our products wherever it makes sense to do so. We achieve this by using renewable raw materials or avoiding energy-intensive raw materials such as cement. This enables us to offer our customers CO₂-optimised products.

What retains its protective function for longer also protects construction works for longer, extends their service life and reduces the need for renewal. Better resistance to climatic influences in turn protects buildings more effectively against the consequences of climate change.
Example: Buildings made of old concrete are particularly challenging. The repair concretes StoCrete TS 126 and StoCrete TS 136 have been specially formulated for this challenge. They have a lower strength and a lower modulus of elasticity. As a rule, these old concretes have higher capillary water absorption and higher weathering in the event of frost attack. With an intelligent air void technology developed for these concretes, the explosive forces of the ice are conducted away in a controlled manner. This technology therefore offers top marks in terms of durability. Maintenance intervals and downtimes are significantly reduced for the construction works. This protects our environment and saves costs.

We offer comprehensive environmental product declarations (EPDs) for many of our products. These document, for example, the carbon dioxide footprint of each product. This makes it possible to compare products with the same intended use. This makes it easier for the consumer to decide in favour of the more environmentally friendly product.

As a supplier of energy-efficient products and systems, Sto makes an important contribution to climate protection. We are also required to constantly optimise our ecological footprint ourselves. We achieve this through certified energy management systems such as ISO 50001 and through many other measures at different levels:
