Travelling "green" can now earn you free stuff, like beer, ice creams or cinema tickets.
So how does it work?
In the Italian city of Bologna, an anti-pollution scheme is rewarding people who get out of their cars and cycle, walk or take public transport instead.
It’s called Bella Mossa or "Good Job!".
Urban planner Macro Amadori set it up in 2017 to make sustainable travel more appealing.
So first you download the "Better Points" app, log your green journeys, and finally swap your points for rewards.
For the first time we have been able to involve all people.
Everybody will have the possibility to change a car trip into a bike trip or into a bus trip and be able to get some discount for his good behavior.
Over 100 local businesses have signed up to give away discount vouchers,
and people compete against each other, to see who can earn the most points.
We decided to try it out, travelling green around the city over a few days.
I got 200 points for that journey.
I still need quite a few more to be able to get a cinema ticket.
The system of point collection is based not on the distance you travel, but on the single trip,
because it’s important that even for short trips of 1km, you do it in a sustainable way.
A GPS tracker makes sure people don’t cheat and are using the form of transport they say they are.
The app also shows how much CO2 you saved on each journey.
You can only log four journeys each day.
So people have to keep using it over time to win rewards.
So that costs me about 3,000 point.
Bella Mossa only runs for six months of the year and has been funded by the EU and Bologna’s local government.
So is it making a difference?
Last year Bella Mossa recorded 3.7 million kms of sustainable journeys just here in Bologna.
Over 16,000 reward vouchers were claimed.
And so far, in the first three months of this year 10,000 people have already used it.
It encourages people to get moving.
Loads of physical activity is always good for people’s wellbeing.
It’s very fun, but we also do it for the rewards,
so I think more and more discounts woud be better.
