Creation of sustainability reports or CSR/ESG reports

On January 1, 2022, new provisions in the Code of Obligations and corresponding implementing provisions came into force. These determine the extent to which Swiss companies must be accountable for their responsibilities. With the Corporate Sustainability Reporting Directive (CSRD) in 2021, EU legislation on non-financial reporting was also significantly expanded.

int/ext supports you in presenting your progress in the area of sustainability/CSR/ESG in a comprehensible and attractive way - from conception and editing to layout. This includes writing meaningful and technically correct content for your sustainability reports based on recognized standards such as the Global Reporting Initiative (GRI). For quantitative reporting, we work closely with your internal specialists and specialized partner companies.​

Internal transformation for sustainability and social responsibility

Coherent internal programs and change communication anchor your CSR or sustainability strategy throughout the organization. They increase employees' awareness and win them over as supporters and ambassadors of the desired change.

We support you in the design and implementation of change processes, for example by advising your company's "Green Team". In addition, we work with you to develop concepts for social commitment or corporate volunteering in order to promote awareness and participation of your employees in sustainability initiatives.
