The environmental impact of indirect operation is determined, which primarily includes the provision of energy. For example, direct emissions at the exhaust pipe, abrasion emissions from brake linings, wheels, road and overhead lines (for railways). The environmental impact caused by the direct operation of the vehicle is recorded. Last but not least, below you find additional context for the categories we applied for breaking down total CO2 emissions into its major components. However, the benefits outweigh the drawbacks as we hope this overview initiates more discussion and joint efforts among the most relevant travel and mobility providers to further slash CO2 emissions.įor exploring the data in more detail, here is the graphic in interactive Tableau format.įor full transparency, we listed all the studies and articles we referenced as well as the assumptions we applied in a separate Airtable: We combined the data for a direct comparison but realize that it’s not a clean apples-to-apples comparison.
To bring more clarity to the ongoing sustainability debate, we collected as many available data points as possible from reputable sources to rank the various urban mobility modes-including the growing number of New Transportation services, such as e-scooters and shared bikes-based on their average carbon-emission output per passenger-kilometer.ĭisclaimer: Our ranking is not illustrating scientifically proven results as the carbon emissions data per transport type is based on existing third-party research with varying methodologies and assumptions.
The transport sector accounts for about 25% of global CO2 emissions, most of them coming from road traffic. The environmental impact of being transported from A to B is significant because transport is a major user of energy, and burns most of the world’s petroleum.
