The key aspects of Sika’s sustainability strategy and reporting were defined through the following activities:

In 2015, Sika has reviewed the materiality analysis which was conducted for the first time in 2013. The analysis focused on potential material topics, reflecting the sustainability impacts of Sika’s operations, products, and services along the entire value chain, considering:

  • GRI standards
  • relevant topics for peers, customers and suppliers
  • expert knowledge


The relative importance of the topics was rated according to the two criteria “influence on stakeholder assessments and decisions” (importance to stakeholders) and “significance of economic, environmental and social impacts” (importance to Sika).

The prioritization from a stakeholder perspective was reviewed in an online survey, whereas the prioritization regarding “significance of economic, environmental and social impacts” was assessed in a series of workshops. The identified material aspects and findings were compared with the results of the first analysis in 2013 and validated by Sika’s Group Management and Board of Directors.

Furthermore, Sika has installed a Sika Sustainability Advisory Board (SAB) which became operational in 2016. The SAB consists of 5 members of academia, advisory and NGO background and has been established to further reduce the company’s environmental footprint along the whole supply chain, and to support a business model based on sustainability. An independent expert opinion aims to provide Sika management with further impulses regarding the direction and implementation of Sika’s sustainability strategy.

The SAB analysed the Sika sustainability practices step by step and has issued a number of recommendations during 2017, which were reviewed by management. This will lead to an adaptation of the measuring and reporting structure. As a consequence, Sika will refine the training and education structure as well as the target setting principles for sustainability for line managers. In addition, a more detailed monitoring of the many social projects will be initiated, so that the company will have an insight into the benefits delivered.

  • Potential reputational impacts
  • Potential of Sika to influence/impact the topic
  • Relevant laws and regulations, Compliance
  • Sika’s risk management
