Quantification of carbon dioxide emitted at trade fairs in the Southwest of Paraná

Abstract

Population growth and economic development have intensified greenhouse gas (GHG) emissions into the environment. On the other hand, science and technology have shown ways to mitigate this impact. The present study aimed to quantify the carbon dioxide (CO2) emitted by the activities of Expofeira Mulher 2019 held in the city of Francisco Beltrão PR, seeking to estimate the number of trees needed for planting in order to offset these emissions. The event took place between April 3rd and 7th, 2019 and had an audience of approximately 60,000 participants, being a very important business fair for the city's economy and moving the southwest region of the state every two years. Using the methodology adapted from the booklet developed by SENAI – Inventory of Greenhouse Gas Emissions – which uses the GHG Protocol program as a basis, it was possible to quantify the carbon dioxide (CO2) generated by solid organic waste and by the transport of participants. From the analyzes carried out, it was observed that transport to the event generated the most CO2, around 94.04 t, corresponding to 98.4% of emissions. To offset the carbon generated at the event, it will be necessary to plant 7345 trees, of which 9 will be related to waste and 7336 to compensate for transport.
