Hannover Re is not only active as a corporate organisation, its employees also get involved. This is exemplified by the "Christmas tree campaign" for St. Joseph Kinder- und Jugendhilfe, a charitable institution that assists children and adolescents in Hannover between the ages of two and twenty who no longer live with their parents. Hannover Re employees regularly help to realise their Christmas dreams in order to make the holiday season more special. Each member of staff who wishes to join in the campaign chooses a present that a child would like to receive. The gifts, wrapped and individually labelled, are jointly handed over to St. Joseph Kinder- und Jugendhilfe.

At Hannover Re's subsidiary in Florida the workforce supports the "New Hope for Kids" campaign: children and their families who find themselves in difficult life situations are assisted with cash donations or through the personal efforts of employees.

The company's branch in South Africa assists students in the discipline of actuarial science and those taking a Bachelor of Commerce degree with a concentration in accounting. Hannover Re also supports needy pupils at a local high school.
