Through the CopenPay scheme, tourists visiting the city will be rewarded for "green actions" – such as using public transportation or cycling – with access to "cultural experiences", free meals etc.

For example, arriving at the CopenHill dry ski slope by foot or on a bike will get you 20 free minutes of ski time, while anyone who volunteers at an organic urban farm will get a free lunch (vegetarian, naturally).

The official CopenPay website describes the purpose of the system as follows:

…to encourage sustainable behaviour and enrich the cultural experience of visitors and residents in Copenhagen by transforming green actions into currency for cultural experiences.

WonderfulCopenhagen.com adds:

There is a need to change the mindset of tourists and encourage green choices […]Through CopenPay we therefore aim to incentivize tourists' sustainable behaviour while enriching their cultural experience of our destination. It is an experimental and a small step towards creating a new mindset […] The hope is not only to continue the pilot project, but also to inspire other cities around the world to introduce similar initiatives.

Now, complimentary organic meals and free windsurfing lessons might seem benign enough, but any talk of "changing mindset" and/or "encouraging behaviour" makes my brain itch.

It's pretty easy to see through the happy-clappy tone of the promotion to the heart of the issue, it's right there in their own words: Transforming green actions into currency.

This is climate change based behavioral modification. This is a social credit system. Small scale and optional, sure, but there's no denying that's what it is.

For now it's optional and only for tourists. They are testing the waters. Barring a catastrophic failure it won't stay that way for long. They likely won't ever make it mandatory to take part, rather – like bank accounts and cellphones – opting out will simply be too difficult for most people to bother with.
