Carbon offsetting Green Mail (Correio Verde)

Green Mail is both sustainable and practical, focussing on convenience combined with environmental protection. All the packaging is produced using eco-design options and the delivery service includes compensation for carbon emissions resulting from its own transport and delivery activities.


For this purpose, CTT supports carbon offset projects that have environmental benefits, namely in the fight against climate change and the promotion of biodiversity, as well as social benefits, such as generating employment and improving the quality of life of local communities.
This year, we're inviting people to take part in the selection of two projects that suit them best (one national and one international) and the ones with the most votes will be supported by CTT both this year and the following year.
