DHL is completely free to decide whether activities count as charitable causes or not. However certain rules will always apply. They MUST NOT be for profit, fraudulent or involved in illegal activities. They must not harm DHL's reputation, or represent a breach of DHL’s policies or values.
A cause cannot be an individual person.
An entry cannot glorify the use of alcohol, drugs, weapons or pornography, or support political groups/parties. Nor can an entry discriminate against race, age, sex, disability, sexual orientation, ethnicity, religion, political orientation or national origin.
If DHL is prevented for any reason from being able to make a donation to the charitable cause chosen by the winner, then another charitable cause may be mutually agreed with the winner.
