Sustainability

Our meaningful contribution – considered and consistent

We make our biggest contribution to sustainable development through our projects. Yet that alone is not enough. We consciously address, in depth, all aspects of sustainability and take far-reaching measures to achieve our goals. 

About

Sustainability Report 2023

Every two years, we provide information on the status of sustainability in our company. This report is based on data from 2023. We report on how our company is developing in terms of sustainability based on aspects that are important to us in the economic, environmental and social areas. We also provide portraits of projects as examples of how our work has a positive impact - on natural habitats, aquatic ecosystems and air and water quality.

Our RESPONSIBILITY

Holistic sustainability

We take responsibility for society and the environment – both in-company and in projects. Taking a holistic view, we strive for social, environmental and economic sustainability.

Our commitment

A better tomorrow and day after

In projects, we take all stakeholders into account and balance environmental and social benefits and economic viability. Internally, we focus on what we can influence most effectively – the energy we use for our offices, IT infrastructure and transport needs. Our actions are thoughtful and far-sighted and we are committed to constantly optimising.

Our goal

Net zero by 2030

We are pursuing the goal of achieving net zero greenhouse gas emissions by 2030. That means we are consistently reducing avoidable emissions and offsetting unavoidable residual emissions by reducing CO2 accordingly.

37% ladies

Compared to other professions, the proportion of women in engineering professions is low, at around 16% in 2015. At HOLINGER, the proportion of women in 2023 is 37%, which is higher than at other engineering companies.

Ecologically produced

Our electricity mix is made up of around 80% hydropower, 11% renewable energies and 9% non-renewable energies (incl. nuclear energy).

Heat from wastewater

Our project to expand the wastewater treatment plant in Collombey-Muraz (Switzerland), is contributing to sustainable development. By using a heat pump, we extract heat from the treated wastewater to heat the digestion tower and the buildings.
