Business Intelligence Homework
The focus of this work is to understand the impact of the air pollution both in the environment and in the people themselves. The data used has historical information about the controlled substances (such as CFGs) usage, CO2 emissions and air pollution level in different countries, and information about the deaths related to it, the earth temperature and ozone hole size. The goal is to assess if CO2 emissions have direct impact on those other things, through different types of data visualization.
Results
The resulting report can be seen in the following link, with all conclusions taken from the data: PowerBI Report.
