We, not only as the brand Doppelherz but also as the company Queisser Pharma GmbH & Co. KG, have a social responsibility to limit global warming and to reduce human-caused CO2e emissions, as well as to avoid the use of plastic in our product packaging wherever possible.
Looking to the Future
Products from Queisser Pharma GmbH & Co. KG are made with the aim of minimizing unnecessary waste and climate damage. In the long term, we are setting clear goals for even greater reductions in packaging material and the use of sustainable materials for product packaging. With the savings achieved so far and the long-term reduction in packaging material, we are already making an active contribution to environmental and climate protection. More information can be found here.
Carbon dioxide is emitted during packaging production, and we aim to further reduce this amount in the future. Unfortunately, CO2e emissions from production cannot be completely avoided.

We continuously work on solutions to offer more environmentally friendly packaging materials for our products.
Ingredients and Sustainability
High-quality of ingredients are the top criterion for our products. Various quality seals and standards confirm the purity and sustainability of the raw and active ingredients.
Ecological Responsibility
We have a significant interest in the conservation of resources. As early as 1997, we were certified according to the environmental standard DIN EN ISO 14001*. The aim of the standard is to combine continuous improvement of environmental performance with the compliance with environmental laws. We also became certified according to DIN EN 50001* in 2016, as one of the first companies, in accordance with legal requirements. As such, we introduced an energy management system based on capturing energy flows within our company as well as an assessment of energy efficiency. These evaluations served as the basis for technical measures that helped improve energy efficiency. Thus, we are able to promote a sustainable use of water and energy resources. Currently, certification according to DIN EN 16247-1* is underway – energy efficiency remains an important topic for Queisser Pharma GmbH & Co. KG.
*The certifications mentioned in this section refer to the scope of the German area Flensburg/Handewitt where our headquarters is based.
The product manufacturing process is also taken into consideration in accordance with legal requirements. The quality of raw materials as well as the continuous auditing of contract manufacturers are assessed with regard to their environmental relevance.
Queisser Pharma uses electricity from 100% environmentally friendly green energy. This way, we support environmental protection and climate conservation in a sustainable way. We receive our green energy from hydropower, a renewable energy source. The corresponding certificate from our local energy supplier can be found HERE .
