The fight against climate change is one of the most challenging missions of our time. Climate change is a global phenomenon and the way in which energy is used has a strong impact on the environment. For this scope, all industries must address energy consumption and greenhouse gas emissions, especially in terms of CO2. This thesis, in collaboration with Iveco Group, aims to assist in identifying energy efficiency projects in the industrial sector, in order to reduce energy consumption and determine a reduction in CO2 emissions. The first step is to become aware of the current situation to develop the optimal strategy.
