• Priorities


Sustainability is a broad concept. To really achieve something, it's important to make clear choices and focus on a limited number of goals. The model that A.Hak uses to make these choices is named 'materiality determaniation'.

What's important?
Using the materiality determination, a top 3 of primary objectives was determined, being:

  • health & safety
  • energy & transport
  • education & training

When it comes to safety it goes without saying that zero accidents is our goal. Yet at the same time we realize that this number is extremely difficult to attain. Our carbon footprint is one of the key indicators to measure our performance regarding energy & transport.
