Paving the way for True Cost
Accounting
The "True Cost - From costs to benefits in food & farming" initiative was originated by Soil & More Impacts and the "TMG Think Tank for Sustainability". The aim is to make the true costs of food production visible in company balance sheets, thus accelerating agricultural transformation. Companies such as EY, GLS Bank, the Hipp Group, Martin Bauer, Lebensbaum and Misereor all participate in the initiative.
2007
Foundation of Soil & More
by Tobias Bandel and partners
The initial focus was on building composting systems to sensibly utilise harvest waste, build humus and store CO₂.
Very soon after this, we also applied our know-how to sustainability consulting. In doing so, we place a constant emphasis on observing the entire agricultural supply chain, collect primary data from farms, classify it and use it to develop strategies for sustainable agricultural practices.

Anne Bandel
Project Manager

Anne grew up in Northern Germany where she spend a lot of time at the farms of both her grandparents. Running over the green fields and feeding the pigs was always her favorite.

Anne studied communications and engaged herself in a student initiative for ethics in education and practices (sneep). Her working life started in a consultancy for corporate responsibility Schlange & Co., Hamburg, Germany. The team mainly develops sustainability strategies and reports for larger sized companies in Europe and conducts studies for German ministries and industries. With this experience Anne went to Egypt to work at SEKEM, a company that started 1977 to harvest herbs in the middle of the desert. Since then, the company has grown to a group of seven companies covering various supply chain steps of agriculture and its products. Anne was responsible for the sustainability management framework – the Sustainability Flower – and reporting on its basis. Here she found again her roots in agriculture.

Since 2012 the work on the Sustainability Flower, which is originally an initiative of various companies from the organic sector, has been continued within the Soil & More Foundation. Relocating back to Hamburg, Anne focused on using the Sustainability Flower as basis for farm and company analysis and reporting. She developed expertise in IT solutions and data processing. Today, she brings in this knowledge to Soil & More Impacts.

Tanja Doucet
Junior Consultant Impact Assessment

Tanja joined Soil & More Impacts in 2019. She supports the team with impact assessments, reporting and general project management.

She completed a bachelor’s degree in Food Science and Nutrition and gained experience in product development. As she was interested in more than only the nutritional value of food, she started studying her master’s in Sustainability Science to learn about the origin of the raw materials and their cultivation.

The fact that our agriculture has a major impact on biodiversity and our climate, motivates Tanja to foster a more sustainable industry and to contribute in creating fertile soil for future generations.

Clara Larissa Wriessnegger
Impact Assessment Specialist

Clara joined the team in the beginning of 2022 and supports our clients mainly in the areas of GHG accounting and climate strategy consulting. She completed her bachelor’s and master’s degree in environmental science and modelling with a focus on climate and oceans.

She approached the topics of “agriculture and food” early on through a personal interest in alternative farming methods and sustainable nutrition. After her studies, she gained first professional experience in this field through life cycle assessments of different crops and processed foods. To bridge the gap from just accounting to visible “impact”, she joined Soil & More Impacts.

Additionally, Clara is also an avid wilderness educator. In her opinion, in addition to scientific knowledge and strategic implementations, it takes a personal connection to nature to be able to protect it holistically.
