An approach to acquiring knowledge of the personal carbon footprint in Cartagena, in the Colombian Caribbean region

CO₂ is the main greenhouse gas due to the large volumes emitted by anthropogenic activities, which is why it is necessary to implement strategies that allow the identification of potential sources of CO₂ emissions in order to design and implement strategies to reduce them. The aim of this research was to estimate the personal carbon footprint in the city of Cartagena. Through the use of a calculator available on the web and the use of social networks, the personal carbon footprint was estimated and its relationship with some sociodemographic and spatial aspects was characterized. The carbon footprint of the inhabitants of Cartagena varies between 0.4 and 17.6 TonEquivCO₂ per year, in addition, there were no differences in terms of sex and age groups. On the other hand, the personal carbon footprint at the spatial level is relatively homogeneous, with a slight distribution of values greater than 9 TonEquivCO₂ in the area where people with a lower socioeconomic status live. The results suggest the need to prioritize strategies to reduce the carbon footprint in these places.
