| The global warming potential of production and consumption of Kenyan tea | The functional unit is defined as 1 kg of dry tea and the tea is assumed to be consumed in the UK. The results suggest that the total impact of tea is equal to 12.45 kg CO2 eq./kg of dry tea for the large-scale and 12.08 kg CO2 eq./kg for the small-scale production, indicating that the scale of production does not influence the impact. The main contributor is tea consumption which is responsible for 85% of the impact because of the electricity used to boil water. Tea cultivation and processing contribute around 10% to the total. The contribution of transport is relatively small (4%). | 12.45 |
