Copenhagen rewards eco-friendly tourists

COPENHAGEN — Tourists visiting Copenhagen this summer are encouraged to participate in unusual kinds of vacation fun, including plucking floating trash from the Danish capital's waterways, cycling to museums instead of going by car, or volunteering at an urban garden.

All these activities are part of a new, four-week pilot project called CopenPay that rewards tourists for "climate-friendly actions".

"We must turn tourism from being an environmental burden into a force for positive change," said Mikkel Aaro-Hansen, CEO of tourist board Wonderful Copenhagen, which runs the program.
