Heller supports reforestation projects in Germany

Forest fires, droughts, floods and hurricanes: the consequences of climate change are visible all over the world and are becoming increasingly clear. Accordingly, the topic of sustainability is more relevant than ever before - also for Heller. To contribute to climate protection, we support the PLANT-MY-TREE organisation with tree donations. Trees not only serve as erosion protection and as a habitat for various animals and plants, but they also reduce the amount of CO2 in our air. That is why they are particularly valuable in counteracting climate change and bringing the ecosystem back into balance. The organisation PLANT-MY-TREE takes care of the reforestation of forests all over Germany. Our team planted the donated trees themselves and sowed the Tree of the Year, the copper beech, as well as many oaks.

The Serafin Group donates to humanitarian aid in Ukraine

Our shareholder, the Serafin Group, is deeply shocked by the current situation in Ukraine. The suffering for the civilian population due to the war is immense.

The company would like to contribute to the support of the Ukrainian population and has therefore decided to provide emergency aid. Serafin wants to support humanitarian aid on the ground with a donation of 500,000 euros and at the same time express solidarity with Ukraine.

The emergency aid will be used to support the civilian population in need. For this purpose, Serafin supports several organisations in providing donations in kind and in transporting aid to the region.

Heller supports moorland protection with a moorland sponsorship

Moors make an important contribution to climate protection. They extract carbon dioxide from the atmosphere and store it in their peat soils. And although they only cover a small part of the land area, they bind twice as much CO2 as all the forests on earth put together. Moreover, moors are a habitat for numerous animal and plant species, many of which are very rare and endangered.

Unfortunately, 95% of the world's moorland have already been destroyed or drained, releasing CO2. This massively promotes global warming. In addition, all animal and plant species are losing their habitat and are thus threatened with extinction.

The WE WANT MOOR association is committed to protecting the moors on a voluntary basis and works with its members to educate the population about the problem. With a donation or a sponsorship, you can contribute to the active implementation of projects for environmental and climate protection. In several steps, the moorland is then renaturalised and thus regenerated through appropriate irrigation processes.

Heller has decided to support the work of WE WANT MOOR within the framework of a sponsorship.
