GIZ’s whistleblowing system

Any violation of a law, internal rule or personal commitment can cause harm – to people outside the company, to an individual GIZ employee or to GIZ as a company. 

GIZ's whistleblowing system is a vital early warning system for identifying potential grievances and initiating effective countermeasures. The objective is to avert or minimise possible damage within or outside the company as early as possible, which may result from the misconduct of individuals or from errors in the system. 


We encourage all of you to report any legal violations or rule-breaking that is relevant to the work of GIZ. To make this possible, GIZ has set up an extensive whistleblowing system, which you can use to submit reports, especially on the following:

  • Corruption and bribery
  • Misappropriation, fraud and embezzlement
  • Conflicts of interest 
  • Sexual misconduct and sexual exploitation
  • Violations of human rights

GIZ always follows up on all grievances reported and ensures they are investigated resolutely and fairly. For this purpose, a standardised and transparent processing procedure with deadlines was developed. GIZ also does all it can to ensure there are no negative repercussions for the whistleblower, provided there was no wrongdoing on the part of the informant.

How to blow the whistle

The whistleblowing system offers the following options for reporting information and can also be used anonymously:  

  • Online whistleblowing portal: The whistleblowing portal is available for use worldwide 24/7 in several languages. Information can be communicated anonymously in keeping with the highest security standards, without having to leave an email address or telephone number. 

    Access to the online whistleblowing portal: https://www.giz.de/tell-us

Please be assured that your impartial and independent personal contacts at GIZ will practise objectivity and confidentiality at all times. 

An external ombudsperson is available to contact outside the company. By virtue of their role as a legal professional, the ombudsperson is subject to a confidentiality obligation in all dealings with GIZ and maintains the utmost secrecy when receiving information on economic criminal activity. The ombudsperson only contacts GIZ and forwards the reported information with the whistleblower’s consent. Where necessary, this can also be done anonymously.

Tips for whistleblowing 

Information can be processed most effectively if the matter at hand is described as conclusively as possible. Informants can use the following questions to help them describe the matter they wish to report on: 

  • What kind of violation/breach has taken place? 
  • How was it perpetrated?
  • Who did it (person(s), name of company/ies)
  • Where did the incident take place (project name, place, country)?
  • When did the incidence take place (time, date)?
  • What proof/indication is there to support your assertion?
