This paper investigates a novel methodology for measuring greenhouse gas emissions by re-evaluating the packaging and transport systems of local communities at a time when concerns about environmental sustainability and the fight against climate change are increasingly heightened. The research first presents CO2 emissions data associated with each logistical sub-process and the methodology used to calculate the CO2 emissions associated with the products. Then, the analysis of a local community-owned asset exchange is presented. Based on the packaging size and weight of the items, calculations are made of the CO2 impact of transporting a product from different distances. The results are also analyzed by investigating the activity of the local community with four different modes of transport and then comparing the amount of CO2 emitted to the population of a city. The study demonstrates that freight transport operations are a significant source of greenhouse gas emissions and seeks to identify opportunities that could lead to significant carbon footprint reductions through community initiatives. The paper points out that even a local community exchange of goods could make a significant contribution to reducing global CO2 emissions. Therefore, in addition to measures to tackle greenhouse gas emissions, implementing a "Think globally, act locally" policy would contribute significantly to CO2 emissions reductions.
