Explore the latest research commissioned by UNIKA and DKHV shedding light on the carbon footprint of potato production and processing. Delve into how fresh potatoes contribute to a greener future in agriculture, emphasizing sustainability practices for farmers and stakeholders.
In the quest for sustainable food production, potatoes play a vital role not only in Germany but also globally. As one of the primary staple crops, potatoes rank fourth in worldwide production, following maize, rice, and wheat. Amidst the growing concerns over sustainable food production, the carbon footprint of agricultural products, including potatoes, has become a focal point of discussion.
To address these concerns, the Union of German Potato Economy (UNIKA) and the German Potato Trade Association (DKHV) commissioned a literature review on the CO2 footprint in potato production and processing. Conducted by the team of Prof. Dr. Elke Pawelzik and Dr. Marcel Naumann from the Georg-August University of Göttingen, the study aimed to assess current practices and identify potential areas for improvement.

The study, which analyzed a multitude of publications, predominantly relied on results from life cycle assessments (LCAs) following the cradle-to-gate approach. Despite the challenges posed by varying research methodologies, the findings revealed that the cultivation of fresh potatoes generates approximately 50% fewer greenhouse gas emissions compared to studied cereal crops. This disparity persists even when comparing fresh potatoes to processed potato products, as additional processing stages impact the CO2 balance.
Furthermore, the literature review identified potential measures to further reduce CO2 emissions during potato cultivation, such as optimizing and minimizing the use of nitrogen fertilizers. However, the researchers emphasized that the CO2 footprint is influenced by numerous variables, including growing conditions, necessitating tailored strategies for emission reduction.
This research contributes to a deeper understanding of the intricate relationship between potato production and environmental impact, paving the way for more sustainable agricultural practices.
Conclusion: The findings from this literature review underscore the positive environmental impact of fresh potato cultivation and highlight the importance of sustainable practices in agriculture. By recognizing the lower carbon footprint of fresh potatoes compared to other crops, farmers and stakeholders can embrace strategies that promote environmental stewardship while meeting the demands of a growing population.
