Nowadays, the label is given by an independent auditor who declares that the internal tests (ISO yield and DIN) meet the requirements of Nordic Swan. In other words, you cannot declare yourself Nordic Swan certified. This is probably the reason that currently only 7 companies offer certified toner cartridges according to the new Nordic Swan regulations.
Safe choice for ecology, quality and health
Using laser cartridges several times reduces the total consumption and accordingly the environmental impact of the product throughout its service life. The label guarantees among other things that climate requirements are taken into account, and that CO2 emissions (and other harmful gasses) are limited. This is not only important for the environment in general, but for the personal health of end users as well.
