Our CO2 offsetting for 2021/22

After our compensation payment to atmosfair on 27 December 2021, we have now also compensated our CO2 emissions for the first half of 2022. As usual, we calculated our CO2 emissions from May 2021 to May 2022 with the help of a CO2 calculator (35,000 kg) and determined the total amount required for compensation (EUR 800). We then rounded up this amount to a total of EUR 1,000 and donated the money to atmosfair. You can find the donation certificates here.
We are happy to continue to be a climate-neutral law firm. However, since this should not be the end of our efforts for a better future, for 2021/2022 we have, for the first time, paid more than would have been necessary to offset our carbon footprint. We have thus taken the first step towards becoming a "climate positive company". However, we do not intend to stop there. In the future, we will do everything in our power to help other companies and individuals to reduce their carbon footprint. As soon as there is something to report in this regard, you will find out here.

Heiner Kahlert appointed as CAS arbitrator

A few days ago, Heiner Kahlert was admitted to the list of arbitrators of the Court of Arbitration for Sport (CAS) in Lausanne. In addition to his experience in commercial and investment arbitration, Heiner also has more than a decade of experience from numerous CAS arbitrations, first as an ad-hoc clerk to CAS tribunals and then as counsel representing parties before the CAS. In moving into the arbitrator role, Heiner follows the example set by the founder of our law firm, the late Dr Dirk-Reiner Martens, who was already on the CAS arbitrator list when the CAS was founded and who was subsequently appointed in nearly 200 CAS proceedings, including at four Olympic Games.
The CAS acts, on the one hand, as a “supreme court” for appeals against decisions of sports federations from around the globe. On the other hand, the CAS also decides as a regular court of arbitration on a wide variety of contractual disputes related to sport. Arbitrators in CAS proceedings can only be those persons who have been admitted to the list of arbitrators. Heiner Kahlert is now one of 15 CAS arbitrators with German nationality.
