The Environmental Agency's climate protection team and the NEST nature exploration station are once again inviting people to take part in the environmental challenge. This year, everything revolves around ideas for heat protection. What can you do to keep a cool head? Anyone interested can send a picture or write how they cool down or protect themselves or their home from the heat.

The organizers are looking forward to receiving contributions by 1 September to the e-mail address klimaschutz@stadt.wolfsburg.de with the subject "Environmental Challenge". The author must be named in order for the photos to be published. The first person to submit a photo or written tip will receive a small thank you for their efforts. In addition, three submissions will be published at random on the city of Wolfsburg's website.

All information on how to take part and tips for hot days can be found at www.wolfsburg.de/nest
