Ghana made an improvement in the 2013 corruption index with a score of 46 out of 100 and ranked 63 out the 177 in the latest ranking by Transparency international (TI). The score is an improvement in last year's ranking of 64 with a scoring 45 out of 100
A country or territory's CPI score indicates the degree of public sector corruption as perceived by business.
Transparency International's Corruption Perceptions Index 2013 offers a warning that the abuse of power, secret dealings and bribery continue to ravage societies around the world.
More than two thirds of the 177 countries in the 2013 index score below 50, on a scale from 0 (perceived to be highly corrupt) to 100 (perceived to be very clean).
"The Corruption Perceptions Index 2013 demonstrates that all countries still face the threat of corruption at all levels of government, from the issuing of local permits to the enforcement of laws and regulations," said Huguette Labelle, Chair of Transparency International.
In the Corruption Perceptions Index 2013, Denmark and New Zealand tie for first place with scores of 91. Afghanistan, North Korea and Somalia this year make up the worst performers, scoring just 8 points each.
"The top performers clearly reveal how transparency supports accountability and can stop corruption," said Labelle. "Still, the better performers face issues like state capture, campaign finance and the oversight of big public contracts which remain major corruption risks."
The Corruption Perceptions Index is based on experts' opinions of public sector corruption. Countries' scores can be helped by strong access to information systems and rules governing the behaviour of those in public positions, while a lack of accountability across the public sector coupled with ineffective public institutions hurt these perceptions.
The report indicates that corruption within the public sector remains one of the world's biggest challenges, Transparency International said, particularly in areas such as political parties, police, and justice systems. Public institutions need to be more open about their work and officials must be more transparent in their decision-making. Corruption remains notoriously difficult to investigate and prosecute.
Future efforts to respond to climate change, economic crisis and extreme poverty will face a massive roadblock in the shape of corruption, Transparency International warned. International bodies like the G20 must crack down on money laundering, make corporations more transparent and pursue the return of stolen assets.
"It is time to stop those who get away with acts of corruption. The legal loopholes and lack of political will in government facilitate both domestic and cross-border corruption, and call for our intensified efforts to combat the impunity of the corrupt," said Labelle.
