our sustainability goals 

Gender equality

Equality is something that the industry needs to improve on. We have ambitions to make a difference. We will work for greater equality and for everyone to be treated equally irrespective of their gender: to have the same opportunity to increase their expertise and develop their career, and to receive equal pay for equal work.

Clean energy

As far as possible, we will use clean energy in our day-to-day operations and in our projects. For instance, through our choice of suppliers, we will choose sustainable and environmentally friendly products. 

Less inequality

We will work to reduce social, political and economic inequality – regardless of gender, ethnicity, religion or origin. We will be an inclusive company where no one is excluded. 

Responsible consumption and production

It is of great importance to us that our deliveries and our consumption are sustainable. We achieve this by means of our delivery concept, focusing on installation technology, material selection, packaging, transport and correct waste management.
