On 31.10.2018, the project partner Pro-Akademia sent out a newsletter to a broad circle of Polish and German courier service providers. The aim was to communicate the project results relevant to these service providers. In particular, the measures for the conversion to a CO2-neutral company developed in WP 2 were presented. In addition, background information on the relationship between emissions caused by the transporation sector and climate change as well as possible compensation measures was given to the more than 1,300 addressees.
