Since 1993 Transparency International has been hugely successful in overcoming the taboo of corruption by engaging decision makers and media around the world. International organisations such as the European Union, the African Union, the World Bank, the United Nations and the OECD have adopted many of TI's ideas and principles. These organisations now tackle corruption as a key priority while they address issues such as poverty and international security. The following list is not exhaustive but provides an overview of many of TI's achievements:
- TI and Social Accountability International have worked with some of the world's largest companies in developing a set of Business Principles for Countering Bribery. The principles are already being used by companies around the world.
- TI launched an initiative with Citibank in 2000, known as the Wolfsberg Group of banks, which formulated a set of anti-money laundering principles for private banking. The principles pay attention in particular to issues related to the laundering of funds gained through corruption.
- TI national chapters promote greater transparency in election campaigning via the Visible Candidates project. Candidates are publicly called to issue statements about their financial history, campaign financing, their political record and their policies, and a database of candidates is compiled and disseminated to the media on the basis of their submissions.
- TI has worked with businesses and governments on the introduction of Integrity Pacts to help governments, businesses and civil society groups prepared to fight corruption in the field of public contracting. Integrity Pacts have now been used in Argentina, Columbia, Ecuador, Italy, Mexico, South Korea and Pakistan, and the concept has been used in other applications in Nepal and Panama. For example, the tender for the technological turnaround of the Banco Agrario in Colombia in 2002 resulted in a 30 per cent saving on the budgeted price.
- TI has been actively involved in the drafting process and monitoring of the OECD, OAS, African Union and the United Nations conventions against corruption.
- TI was recently successful in placing the fight against corruption as the tenth principle in the UN Global Compact (an agreement which has been signed by over 1700 business and NGO organisations). Based on advice from TI, The World Bank Institute, now regularly and publicly reports on the prevalence and economic effects of corruption.
