The research examined what causes CO2 emissions and energy use changes in Colombia over 40 years. They found that more CO2 emissions came from a richer population and more people, but this was partly balanced by factors like energy use efficiency. Energy use reduced mainly in specific sectors like transport due to better efficiency. Overall, the data suggests that improvements in how energy is used in different sectors, like in transport and industry, played a big role in cutting energy intensity and emissions in Colombia. The study helps give insight for making better energy and environmental policies.
