Partner to the dena pilot study "Towards Climate Neutrality"

Together with more than ten scientific institutes, over 70 business representatives and a 45-member advisory board with experts from science, politics and society, the German Energy Agency (dena) defined decisive fields of action and approaches to solutions to achieve climate neutrality in Germany by 2045. In total, 84 tasks were identified in central fields of action. The energy industry, the construction industry and transport were thereby considered.

terranets bw took part as a partner in this study, in particular in the energy module, and agrees with the core concerns set out in the study.

Our projects 
for sustainability in the region

Restoration of moors in the Reinhardwald Nature Park in Hesse

Together with Bergwaldprojekt e.V., terranets bw implemented the rewetting of the Lempenmoor in the Rheinhardswald Nature Park in Hesse in October and November 2023. The focus was on raising the water level and redistributing the water so that the slope water is diffused and spread over the area. The project thus makes an important contribution to climate protection, biodiversity and improving the water balance in the landscape.
