In the EPD (Environmental Product Declaration) issued and recalculated on 28.03.2024, we now also make visible the improved energy supply for the production of KIELSTEG timber construction elements through a PV system since 2022.  The EPD is certified in accordance with the European regulations ISO 14025 and EN 15805+A2 and is also used by our sales partners inside and outside the EU. Building with wood has the potential to significantly support the reduction of CO2 emissions. We therefore see it as our responsibility to improve the CO2 footprint of our KIELSTEG elements and to disclose the CO2 balance over the entire life cycle from cradle to grave for architects and planners. With the EPD, we also support experts in verifying CO2 indicators as part of the planning of sustainable, subsidized buildings.

We are convinced that:

1. only the long-term use of wood, for example as a building material, is able to keep the stored CO2 in stock for longer than the natural tree would have been able to in its late life cycle.
2. among other things, this gives us time in which a young tree can grow into a relevant CO2 store. Although wood is a natural and renewable resource, its benefits can only be justified if it comes from sustainable forest management. FSC and PEFC certificates confirm this sustainability!
3. In addition to the positive effects of sustainable forest management, the innovative strength of manufacturers is required to optimize the use of wood in products. This goes hand in hand with the need to focus on the durability of products. 
4. architecture and building planning also have a responsibility to create buildings with the greatest possible flexibility of use, which can increase the useful life of the building. This is because a long service life together with a justifiable recycling option with a view to substituting fossil fuels as late as possible are relevant factors that counteract rapid consumption with high resource consumption.
