Transparency International published its Corruption global rankings. 2015 showed that people working together can succeed in fighting corruption with Greece improving its score.

Specifically, the report notes: “Some countries have improved in recent years – Greece, Senegal and the UK are among those that have seen a significant increase in scores since 2012.Others, including Australia, Brazil, Libya, Spain and Turkey, have deteriorated.”

Based on expert opinion, the Corruption Perceptions Index measures the perceived levels of public sector corruption worldwide.

Dark red indicates a highly corrupt public sector. Lighter red and orange countries fare a bit better, but corruption among public institutions and employees is still common. Yellow countries are perceived as cleaner, but not perfect.

The scale of the issue is huge. Sixty-eight per cent of countries worldwide have a serious corruption problem. Half of the G20 are among them.

Not one single country, anywhere in the world, is corruption-free.
