6. Show that you understand the safety and environmental aspects of geocaching, such as the Highway Code, Countryside Code, and the Geocaching Association of Great Britain (GAGB) guidelines.

For the Highway Code part of the badge, I believe the spirit of this is Road Safety for young people when they are out caching in an urban environment. I Like Tales of the Road but there is plenty of available material on road safety.

The Countryside Code offers advice on how you can enjoy your visit to the countryside and how to protect it by acting responsibly. The code explains that is important to plan ahead, stay safe and respect our involvement, what could be more scouting.

Geocaching Association of Great Britain (GAGB) promotes and advises best practices in hiding or finding geocaches in the UK, the leading UK Geocaching body, recognized by and acting on behalf of cachers. They provide very explant support for the hobby for the badge you need to look at (GAGB) guidelines I would also highly recommend Geocaching with Scouts and Guides.
