The sustainability report

«We stand for technology and sustainability in construction. Together, we have committed ourselves to energy efficiency, decarbonisation and the sustainability of buildings throughout their entire life cycle.
In doing so, we are assuming social responsibility and making an important contribution to the conservation, utilisation, protection and promotion of our resources.»

Christian Appert
Group CEO

For us, sustainability means operating the company in a socially and ecologically responsible as well as economically successful manner. We fulfil our corporate responsibility by engaging in all three dimensions. Many of our disciplines provide the necessary impetus, show efficiency potentials and lead to environmentally compatible solutions. We have compiled our commitment in a sustainability report in accordance with the guidelines of the Global Reporting Initiative (GRI). The reporting includes all companies of the Amstein + Walthert Group with their locations in Switzerland and France and their employees.

Our highlights

Due to our commitment for sustainable development, we can look back on many highlights in 2023:

  • We further improved our environmentally friendly mobility offering with additional (electric) bicycles and electric company vehicles.
  • The development of our Code of Conduct was completed at the end of 2023 and widely communicated at the beginning of 2024 as part of the  #amsteinwalthertconnects #sustainabilityinaction campaign.
  • All A+W companies were certified with the esg2go sustainability certificate for the first time.
  • Two interesting customer events on the topic of sustainability took place:  «How ESG is changing the property sector» and «Correctly accounting for greenhouse gases».
  • A+W joined the  «Women in Power» women's network in the Swiss energy sector.

Sustainability targets

The sustainability goals of Amstein + Walthert are based on the Agenda 2030 for sustainable development of the Federal Government and the 17 Sustainable Development Goals (SDG) defined therein. The SDG were adopted by all UN member states in 2015. For each of the 17 goals, the scope of A+W was analysed. Our goals should contribute to achieving the overarching SDG.

Our targets formulated for the 2018 Sustainability Report for the first time are designed for different time horizons. Immediate targets were already addressed in 2018. Short-term targets were set by 2020, medium-term targets by 2025 and long-term targets by 2035.

The targets are structured according to the three dimensions of sustainability: Society

a) Occupational safety will be further increased so that we will continuously reduce the number of occupational accidents from 2018.

b) From 2018, A+W will be a member of the Suva Safety Charter.

c) A+W participates in the external professional training of employees by granting paid training time or financial contributions to course costs.

d) We are constantly expanding our own «A+W University» training and continuing education programme.

e) The transfer of know-how between employees in all areas is promoted with suitable structures.

f) We support flexible, family-friendly working conditions, for example by enabling flexitime and part-time models.


g-i) Amstein + Walthert exclusively purchases energy from renewable and domestic sources at all sites: from 2018 for electricity (g) and subsequently for heat (h) and for the company fleet until 2035 (i).

j) The technical requirements will be implemented to enable employees to work at all A+W sites from 2020.

k) We consistently separate our waste and recycle it wherever possible.


l) We will proactively develop our close cooperation with the scientific community and various research institutes until 2025.

m) The A+W innovation culture introduced in 2018 is implemented. Innovation structures are known and are supported and lived out internally.
