      The Carbon Footprint of Tea

      26 MAY 2025

      The Carbon Footprint of Tea

      Prof. Dr. Üçtuğ, from IUE Department of Mechanical Engineering, collaborated with academics from Izmir Institute of Technology, Dokuz Eylül University, and Adana Alparslan Türkeş Science and Technology University as part of a TUBITAK project led by Prof. Dr. Volkan Ediger from Kadir Has University.

      PUBLISHED IN AN INTERNATIONAL JOURNAL

      Prof. Dr. Üçtuğ stated that they used the life cycle assessment method in their research, which focused on Turkey, and shared details of their study, which was published in an international scientific journal. Prof. Dr. Üçtuğ said, “We obtained data from a tea-producing company in Adana. In our analysis, we considered all aspects, including tea cultivation, transportation, packaging in factories, delivery to customers, brewing, and disposal of tea waste. There were previous research on the assessment of the carbon footprint of coffee and carbonated beverages, but ours was the first study focusing on tea. The results clearly showed that tea has a significantly lower environmental impact than coffee and carbonated beverages in Turkey. For example, a 330 ml can of a carbonated beverage has an approximate carbon footprint of 0.17 kg CO₂ equivalent. For tea, this figure is around 0.014, which is about 12 times lower. For coffee, the number rises to 0.40, meaning tea’s footprint is nearly 30 times lower than coffee. Since carbonated drinks are industrially processed, they undergo extensive manufacturing steps. Meanwhile, coffee is imported and has drying methods that contribute to its higher carbon footprint. By scientifically measuring the carbon footprint of tea in Turkey, we have proven its environmental advantages.”

      “USE ELECTRIC APPLIANCES AND USE THE TEA WASTE”

      Emphasizing the importance of the brewing method, Prof. Dr. Üçtuğ said, “Using electric appliances to brew tea is much more eco-friendly than brewing it on a gas stove. I recommend using electric devices whenever possible. Additionally, tea waste can be composted and used as fertilizer for vegetable and fruit production. Tea waste is valuable, yet we often discard it. These may seem like small steps, but they significantly impact the environment. If we pay attention to these factors, we can further reduce tea’s carbon footprint and minimize its environmental impact.”
