CO2 emissions in cities by Reuters, but submitting personal projects not done for / at work

Interactive visualisation that can be used to view average CO2 emissions of cities worldwide at a glance, as well as to dive into the data for a specific city – both its emissions and trends over time.

My aim with this visualisation was to represent all the available data on one graph, such that the emissions of cities around the world can be compared. At the same time, it doubles as a dashboard whereby clicking on each city gives specific emissions information about it over time.
The visual elements were chosen to represent the notion of 'globe' and 'gas'.

Data by the Carbon Disclosure Project. Includes municipal greenhouse gas emissions data submitted to the CDP between 2016 and 2020 and covering years ranging from 1990-2019. The project was completed over one weekend as part of a hackathon.
