Yes and no. All of our paper comes from forests that are managed correctly and responsibly. But it's not all (fully) FSC® certified. This is because it's very expensive for small (private) forest managers, like we have in Belgium, to apply for the certificate. Because of this high cost, they often don't apply for the certificate and consequently are not certified. Of course this doesn't mean that the forests are not managed properly.
Do you want to be 100% certain that the paper is FSC® certified? Request a quote of the product you'd like. Keep in mind that this can be (a lot) more expensive. The question is whether the certificate is really a requirement, like for some government assignments, or whether you want to do something for nature.
If the latter is the case, you are better off ordering the standard version of the product and donating the difference in money to a nature fund or other charity. This will benefit nature more than ordering FSC® certified paper. If you are not sure, you can always contact us so we can take a look at it together.
