In by far the most countries, you no longer need to bring along the Green Card. The Green Card is proof that you have liability insurance on your car, but nowadays it is enough to just have a licence plate on the car, when you are driving within the EU, including the EEA countries Norway, Croatia, Switzerland, Iceland and Andorra.
Exceptions: You must bring the Green card along to the countries below:
Bosnia and Herzegovina
*Be aware that the Kosovo part of Albania does not accept the Green Card. Here, you will need to take out liability insurance at the border.

The red card is just the SOS telephone number: +45 7010 5052, which provides assistance if you have comprehensive coverage. We recommend downloading the SOS app to your smartphone. The app includes, among other things, a GPS function, which enables SOS to find your geographical location in case of a breakdown abroad.
