DELTA Fiber´s positive impact on people, the environment and society

With our ESG policy (Environmental, Social & Governance), DELTA Fiber aims to ensure a positive impact on people, the environment and society. We also support the Sustainable Development Goals (SDGs) as drawn up by the United Nations. Diversity and inclusion are part of our company philosophy, we contribute to responsible production and consumption, and we limit the impact on the environment with 100% green energy, offsetting our own CO2 emissions.

Our contribution

We make a distinctive contribution to seven of the United Nations SDGs by developing and expanding our fiber network, and by making conscious choices in our business operations. At DELTA Fiber, we do this through four focus areas to ensure our sustainability-improvement initiatives are targeted.

Coastal Marathon Zeeland

The most beautiful but also the toughest marathon to run in the Netherlands. This coastal marathon goes from Burgh-Haamstede to Zoutelande. It’s 42195 meters of climbing and descending along the coast of Zeeland with the wind in your hair, salt on your lips and fantastic views. DELTA is Gold Sponsor of this event and the main sponsor of the Light Coastal Run.

DELTA Dikke Banden Races

DELTA Dikke Banden Races

The DELTA Dikke Banden Races (Fat Tires) introduce little children with cycling as a sport. This way we also keep the youngest generation moving. During a DELTA Fat Tire Race, children aged 3 to 13 can participate in a race in their own village or neighbourhood. The fastest kids get a medal. The DELTA Dikke Banden Races are organised together with SportZeeland.
