Reducing our Carbon Footprint

Our serious commitment to environmental sustainability and carbon footprint reduction is demonstrated by the many initiatives featured on this page.
We have been taking part of A1 group yearly ESG report since 2021, and are tracking our energy use, waste and travel impacts. However, we believe that sustainability is not just a matter of corporate responsibility, but a critical aspect of our business strategy. While we are proud of the progress we have made so far, we recognize that there is always room for improvement and have made several strong commitments for the near future.
