This paper presents the results of the first energetic and carbon footprint analysis in the manufacturing process of bamboo boards in Colombia. The energetic analysis was performed using energetic management tools, with the objective of estimating the energy consumption and the Consumption Index that characterizes the process. Life Cycle Assessment was used for carbon footprint analysis, taking into account the impact category of global warming following IPCC 2007, 100 years and having defined one bamboo board as the functional unit. The energetic analysis indicates an electricity value of 3456.6 kWh non-associated to the boards manufacturing, and a Consumption Index that recommends a minimum monthly production of 400 boards. The environmental analysis considered the avoided emissions due to prevention of remaining waste decomposition on the farming fields. The sum of generated and avoided emissions yields a negative value of – 117 kg of CO 2-eq . This result is due to the use of bamboo waste as a fuel for the boilers. We evaluated an alternative scenario of using natural gas as fuel. This alternative scenario also showed a high sensibility to the variation of critical supplies such as the fuel for the boilers. Which validates the environmental model. [ABSTRACT FROM AUTHOR]

The global contribution of all kinds of organizations to greenhouse gas (GHG) emissions is noteworthy. Calculating, reporting, reducing, and compensating for carbon footprints are the appropriate steps to take to guide companies toward a path that is compatible with their country's objectives for the fulfillment of the Paris Agreement. In Latin American countries, carbon footprint reporting is limited and incipient. This paper aims to start closing this gap by assessing the carbon footprint of a university operating in the city of Bogotá, Colombia. Based on a city input-output table (IOT) nested in a multiregional input-output (MRIO) table framework, we estimate the three categories of the carbon footprint (scopes 1, 2, and 3) identified by the Greenhouse Gas Protocol using an improved multiregional tiered hybrid analysis of the university's energy and other input expenditures. Our results show that 94% of the entire institution's footprint is attributed to scope 3, which represents indirect emissions linked to the upstream value chain. The results allow us to identify emission hotspots and their impact on the supply chain, which can be helpful for reducing costs and encouraging organizations, users, and suppliers to make more sustainable decisions.
