Up to now it was not possible to obtain EUAs from the registers in Germany. It would have been possible to purchase EUAs in Austria, though, but then we would have not been able to delete them by ourselves. This is why we decided to wait until a purchase in Germany will be possible. Our broker said this would approximately be from July on.
Thus, we will soon get in touch with him to see whether a purchase is possible. In case this is so, we will use 90% our savings to purchase a lot of EUAs which will be retired as soon as we obtain them. As of today we have saved up to € 4 670.55.
