About us

Sustainability as competence

In order to be at the forefront, Amstein + Walthert is committed to the three dimensions of sustainability - society, economy, environment - and is constantly implementing new measures in this area. For the long-term and sustainable planning of our commitment, we have developed sustainability goals for the entire Group and have adopted binding targets.
Since 2014, we have been taking a closer look at our environmental impact and publishing a sustainability report every year. This summary provides an overview of our activities in the 2019 financial year. For more information you can click through the detailed report or read the executive summary with the key sustainability figures.


Our company is established throughout Switzerland and in Lyon and Paris (F). In 2019, we employed an average of 1,109 people at 15 locations, with a female share of around 20%. One of our main concerns is the continuous training and development of our specialists and apprentices. In 2019, our employees* completed over 5,500 hours of further training at the internal A+W University.

With our pension fund, managed by employee and employer representatives, we provide for a secure pension plan. In the 2019 financial year, the interest rate on retirement assets was an encouraging 3% (minimum interest rate according to BVG 2019: 1%).

Energy and greenhouse gas emissions

As a company, we need energy in a variety of forms: for heating our buildings, for operating electrical systems or for occupational mobility. In 2019, our total demand amounted to 2,935 MWh (primary energy). While electricity and heat consumption has fallen, the primary energy requirement for occupational mobility has continued to rise (public transport +8.8%, motorised transport +17.5%).
Total greenhouse gas emissions in 2019 amounted to 439 tonnes CO2eq. The increase compared to the previous year is due not only to occupational mobility by car (+20%) but also to the heating of buildings (+15%); the corresponding final energy demand has risen at various locations. Business air travel, which will be surveyed for the first time in 2019, is responsible for 1% of primary energy demand and 2% of greenhouse gas emissions.

In 2019, our employees travelled around 51% of the distances covered by public transport (1% less than in 2018), with the remaining 49% using their own vehicle, the company fleet or Mobility vehicles.

The survey on commuter mobility carried out at the beginning of 2020 showed that the employees of Amstein + Walthert AG cover around 66% of their working distances (in km) by public transport and 8% by muscle power. The remaining 26% are covered by motorised private transport (car, motorbike, etc.). This means that the modal split has hardly changed compared to 2017. The share of public transport has decreased by 2 percentage points in favour of motorised and non-motorised transport in equal measure.


The reduction of resource consumption is also an important concern of Amstein + Walthert AG. Waste volumes have been reduced in practically all divisions. In 2019, almost 20 kg of industrial waste per full-time employee was generated, almost 7 kg less than in 2017. We recycle about 48% of our waste. Water consumption also fell in 2019 to 194 litres per square metre of energy reference area, or 19 litres per employee* full-time equivalent and working day.

«With our know-how, our passion for innovation combined with tradition and values, we make smart contributions to sustainable sites, civil engineering and building construction projects.»
