Abstract

The objective of this work is to evaluate carbon footprint reduction from vegetables of Bangkok Urban Home Vegetable Garden model (BUG) compared with commercial vegetables.  The BUG model was developed based on appropriate home gardens in Bangkok and applied the concept of pesticide-free agriculture. The information on Bangkok home gardens were obtained from questionnaires by accidental sampling in Bangkok urban area, who are customer of pesticide-free vegetable stores, and who are interested in home gardening. Life cycle analysis was used to evaluate the environmental impact of CO2 emissions of Chinese kale, Chinese cabbage, bird pepper, holy basil and sweet basil for the Bangkok area.  The results revealed that vegetables from the BUG model emit 0.0753 kgCO2eq/kg of vegetable (37.8%) less than commercial vegetables. Total GHG emission of vegetable cultivation and raw material transportation in Bangkok is 6,542,700 kgCO2eq. Total GHG emission reduction for Bangkok is approximately 2,446,655 kgCO2eq in changing from commercial vegetables cultivation and raw material transportation into BUG model for 5 types of vegetables. One of the main GHG emission reduction is vegetables transportation from the other provincial production source to the selling points in Bangkok which account for 992,020 kgCO2eq.
