When app and website users are given quantifiable data that makes them celebrate the choices they have made, they feel good and are more likely to return to those platforms. This is especially true when it comes to seeing how they have made a positive environmental impact.

Passenger apps include a feature which shows users how much C02 they have saved by choosing to take the bus over a car. Now, to match the apps, CO2 savings estimates have now been added to journey plans on websites. 

Savings estimates are also communicated with a randomly selected relatable CO2 usage comparison:

• Cups of tea made
• Mobile phone charges
• Fridge running time
• Lightbulb hours
• TV hours
