This project is about CO2 emissions in the 33 London boroughs and how they evolved from 2005 until 2015. In this visual my focus was to show that central London was the most polluted and that is caused by commercial and industrial activities, whereas it is very clear that the outer boroughs have less pollution. In these boroughs, the major source of CO2 emissions is domestic consumption. This might be the cause of a geographic but also an economic aspect. In this project, I tried to represent the data taken from the London Datastore website and represent it visually through a timeline. The data was huge and contained a lot of details and categories. I started filtering the latter and create a sequence to my visual.
